A METHOD OF REDUCING BANDWIDTH BY SELECTIVELY SENDING MEDIA INFORMATION OVER A COMMUNICATIONS NETWORK

Abstract A system and method for managing communication in an integrated services network ensures that media information is displayed on at least one of two terminals during a call without using any transmission bandwidth. This is achieved by haying at least one of the terminals pre-store the media information in a memory and then controlling the terminal to recall and display this information when certain events occur during the call. The media information may include animated information, images, and short-time video scripts. This information and broader band media such as streaming video may be displayed on the same terminal. The display of media information may also be controlled based on the past knowledge and experience callers have about one another and/or their communications equipment.

SYSTEM AND METHOD FOR MULTIPLEXING MEDIA INFORMATION OVER
A NETWORK USING REDUCED COMMUNICATIONS RESOURCES AND
PRIOR KNOWLEDGE/EXPERIENCE OF A CALLED OR CALLING PARTY
5 TECHNICAL FIELD
This invention generally relates to managing network communications,
and more particularly to a system and method for controlling the communication
of media information over an integrated services network.

BACKROUND ART
In recent years, remarkable technical advances have been made in the
areas of wireless- and Internet-related communications. One application of this
technology focuses on providing bi-directional video conferencing (e.g., video
phone) services over wired and wireless networks. In order to provide real-time
15 streaming video of reasonable quality, a transmission bandwidth of at least 64 K
bits per second is required. This is approximately eight times the bandwidth
required for voice communications, even if a highly efficient compression
scheme is implemented.
One of the most significant stumbling blocks to providing high-quality
20 multimedia video-conferencing services is insufficient transmission bandwidth.

WO 2004/030381 PCT/KR2003/001893

Also, there is great doubt as to whether two-way video phone services will be of
interest to the public, even if these services can be provided at a reasonably
affordable price, to elicit public Interest and therefore to build a strong market
for the video conferencing industry, the inventor of the present invention has
5 realized that social interactions between callers must be encouraged
sacrificing valuable transmission bandwidth. Taking this approach
increase minutes of usage and thus generate revenue sufficient to ensure the
continued advancement of the telecommunications industry.
The inventor of the present invention has also recognized that next-
10 generation communications systems must provide a variety of multimedia
services including real-time streaming video and video-clip swapping, while
simultaneously conserving or reducing transmission bandwidth requirements
and other network resources. Present communications systems do note
adequately provide these services, and the services they do provide are
15 implemented in an efficient manner. A need therefore exists for a system and
method for providing enhanced multimedia services to the public which at the
same time conserves or reduces network resources.
Further, it is noted that currently existing telecommunications systems
cannot deal with abstractions and emotions of callers that are natural to every
20 day interaction. For example, the majority of callers know one another. They

WO 2004/030381 PCT/KR2003/001893
3
know their characters, physical appearances, and other attributes through
past shared experiences and knowledge. Parties also often have knowledge
of other parties' mobile terminals, including the manner in which they are
equipped and their ability to support multimedia and other services. Existing
5 communications systems do not use the prior knowledge and experience of
callers as a basis for reducing transmission bandwidth in providing
multimedia services in a communications system. These systems also do not
use prior knowledge and experience as a basis for reducing the costs
associated with providing multimedia communications.
10 Further, it is noted that conventional communications systems are
required to transmit multimedia information over a network every time these
services are desired to be displayed on a receiving terminal. This frustrates
attempts to conserve transmission bandwidth and adversely affects the
quality of communications of other users.
15 There is, therefore, an additional need for a system and method that
manages communication of multimedia services more efficiently than
conventional systems, by ensuring that transmission bandwidth and other
network resources are not used every time one terminal desires another
terminal to display media information. There is also a need to provide a
20 system and method of this type in a cost- effective manner.
DISCLOSURE OF THE INVENTION
An object of the invention is to solve at least the above problems

WO 2004/030381 PCT/KR2003/001893
4
and/or disadvantages and to provide at least the advantages described
hereinafter.
It is one object of the present invention to provide a system and
method for managing communication of media Information in a network more
5 efficiently than conventional systems of this type.
It is another object of the present invention to achieve the
aforementioned object by ensuring that transmission bandwidth and other
network resources are not used every time one terminal desired another
terminal to display media information.
10 It is another object of the present invention to achieve the
aforementioned objects in a cost-effective manner.
It is another object of the present invention to provide a system and
method for managing communication of media information in a network using
fewer network resources (including transmission bandwidth) than
15 conventional systems, while simultaneously providing an equal or greater
array of multimedia services to customers.
It is another object of the present invention to provide a system and
method which allows a user at one terminal to control the display of
multimedia information based on an identity of a party at another terminal.
20 It is an object of the present invention to provide a system and method
which manages the communication of media information in a network based
on prior knowledge and experience callers have with one another, and more
specifically to use this prior knowledge and experience as a basis for

WO 2004/030381 PCT/KR2003/001893
5
reducing transmission bandwidth in providing multimedia services within a
network without sacrificing the quality of those services.
The foregoing and other objects of the invention are achieved by
providing, in one respect, a highly compressed pseudo-video system which
5 manages the transmission and display of media information in an integrated
services network using fewer network resources than conventional systems.
The network may be a wireless network or the Internet, and the media
information may include real-time video streams, short-time video scripts,
images (e.g., snapshots), live animations, and still animations.
10 In accordance with one embodiment, the invention reduces
transmission bandwidth by having animation, image, and/or short-time video
script information pre-stored in memories located within or attached to the
communicating terminals, instead of transmitting this media information over
the network, the receiving terminal may therefore automatically retrieve and
15 display the pre-stored media information in response to receiving a call from
another user or other events that may transpire during a call.
In accordance with another embodiment, the invention reduces
transmission bandwidth by combining and transmitting high-bandwidth media
such as streaming video and short-time video scripts to a receiving terminal,
20 and then coordinating the display of that high-bandwidth media with lower-
bandwidth media. Since the lower-bandwidth media is pre-stored in the
receiving terminal, no transmission bandwidth is expended in order to be
display the lower-bandwidth media on the receiving terminal.

WO 2004/030381 PCT/KR2003/001893

The present invention also allows for a shifting in the
telecommunication paradigm. In conventional systems, every communication
link relies on the following assumption: communications links are established
is independently from prior knowledge and experience of the communicating
5 parties. Conventional systems, thus, strictly allocate network resources
based on communication protocols. The abstractions, imaginations, and
emotions of callers are never taken into consideration
The present invention takes the abstractions, imaginations, and
emotions of the callers as well as their past knowledge and experience with
10 one another into consideration when managing the communication and
display of media information on user terminals. For example, using prior
knowledge and experience, the communicating parties can control the
amount of information they want to transmit based on how much they are
wiling to pay for various communication services.
15 Additional advantages, objects, and features of the invention will be
set forth in part in the description which follows and in part will become
apparent to those having ordinary skill in the art upon examination of the
following or may be learned from practice of the invention. The objects and
advantages of the invention may be realized and attained as particularly
20 pointed out in the appended claims.

MODES FOR CARRYING OUT THE PREFERRED EMBODIMENTS
The present invention is a system and method for controlling
10 communication of media information between two terminals in a network. In
one respect, the invention controls the manner in which different types of
media information are multiplexed and transmitted between the terminals. In
another respect, the invention controls the manner in which media
information is displayed or otherwise output on the terminals. This control
15 may be performed based on past experience/knowledge one user may have
about the other, or based on a service option selected by one or both of the
users. The invention thus may be customized to meet the specific desires of
each user. Advantageously, the invention may also be implemented to
reduce network resources (Including the transmission bandwidth) that
20 conventional methods would require in order to send media information
between terminals.
Fig. 1 shows an example of a communications system in which the
present invention may be implemented. The communications system

WO 2004/030381 PCT/KR2003/001893
9
includes a network 1 for receiving and transmitting calls within a
predetermined geographic area. The network may be a wired or wireless
network operating in accordance with any one of a variety of communications
standards. To maximize customer subscriptions, a wired-version of the
5 network may be implemented as a wide-area such as the internet. Preferably,
the network is integrated to include a plurality of access points or gateways 2
for connecting terminals through different networks. These terminals include
mobile terminals 3 such as mobile telephones, so-called web phones,
personal digital assistants (PDAs), and pocket computers to name a few. The
10 network may also connect desktop or notebook personal computers 4 either
to each other or to the mobile terminals. Wireless content providers 5 and/or
network content providers 6 may be included as desired.
Fig. 2 shows a mobile terminal 10 which may be configured to operate
in accordance with the present invention. This terminal includes a speaker 11,
15 a microphone 12, a keypad 13, and a display 14 for displaying media
information which has either been pre-stored in a memory of the terminal or
transmitted to the terminal through antenna 15, or both. The mobile terminal
also includes as an optional feature a camera 16 which has the ability of
capturing still images and/or acquiring real-time streaming video in a manner
20 similar to a video phone or video-conferencing terminal. An external data port
17 such as a USB port may also be included for receiving and/or
downloading information including media information from another system 18
such as a personal computer. While the mobile terminal shown in Fig. 2 is

WO 2004/030381 PCT/KR2003/001893
10
preferable for use with the present invention, those skilled in the art can
appreciate that other type of terminals may be used provided they have the
ability to output media information in a manner which will now be described.
Fig. 3 shows an example of a control circuit which may be used to
5 display media information on a wireless terminal configured in accordance
with the present invention. This control circuit includes a processor 20
connected to the antenna (not shown), an optional caller ID unit 21, a
memory 22, a keyboard 23, a camera 24, and a data port 25. The caller ID
unit extracts identification information from a call indicating an identity of a
10 caller. This information may include the caller's telephone number, name,
address, etc.
The memory may include an area for storing media information which
may either be displayed on the terminal itself or transmitted for display on
another terminal. The media information may be pre-stored In the terminal
15 memory or received from another terminal for display. To control the display
of media information, the memory may include an on-board personal
information management (PIM) database. This database may operate based
on information derived from the caller ID unit, control information Input by a
user, information downloaded to the terminal from an external computing
20 system, or any combination thereof. If desired, the P1M database may be
located in a personal computer or other external computing device which
interfaces to the terminal through the data port. The data port may also be

WO 2004/030381 PCT/KR2003/001893
11
used to load media information into the memory of the terminal for
subsequent transmission or display.
The processor of the terminal may also be used to combine, or
multiplex, media data for transmission through its antenna. This media
5 information may be stored in the on board memory, imported from the
external computing system, or both.
Prior to receiving a call, a user may set the parameters of operating
software 26 in the processor for controlling, inter alia, the manner media
information is to be displayed on the terminal. The user may also designate
10 one or more media service options he or she would like to receive. These
options may control the type of media information to be received in order to
reduce service charges or, if cost is not an issue, enhance terminal operation
to receive and display broadband media. Service options may be negotiated
with the carrier directly or set by inputting information using the keyboard
15 terminal.
When a call connection is established, the processor displays media
information based, for example, on the control parameters and/or service
options designated by the user. This media information may be stored in
memory 22, received from a transmitting terminal on display 28, or both. The
20 manner in which media information is communicated between terminals for
display will now be discussed.
Fig. 4 is a flow diagram showing steps included in a method for
controlling communication of media information in accordance with a first

WO 2004/030381 PCT/KR2003/001893
12
embodiment of the present invention. This embodiment combines, or
multiplexes, different types of media information in one terminal for
transmission to a receiving terminal within a same transmission period. The
method begins when the transmitting terminal initiates a call with the
5 receiving terminal. (Block 30). As previously discussed, the call may be
initiated through a wireless network, the internet, or any other type of wired
network.
Once a call connection is established, the transmitting terminal
combines, or multiplexes, first media information and second media
10 information in an output transmission stream. (Block 31). This media
information may be selected by a user, for example, through operation of a
terminal keypad in conjunction with a displayed menu. The media information
may take any one of a variety of forms, including the following:
• streaming video (either pre-stored or real-time)
15 • short-time video script (e.g., a MPEG file)
• image (e.g., a JPEG file)
• still animation (e.g., a graphical interchange format - GIF)
• live animation (e.g., a moving GIF)
The types of media information listed above may be combined, or
20 multiplexed, in any order, or this information may be combined based on the
transmitting terminal user's knowledge of media information that is pre-stored
in the receiving terminal. These features of the invention will be described in
greater detail below.

WO 2004/030381 PCT/KR2003/001893
15
the invention is particularly desirable for purposes of customizing operation of
the terminal to each specific user.
While the invention has been described as storing media information
in a terminal memory, those skilled in the art can appreciate that the terminal
5 may also be Interfaced to an external memory which stores and retrieves
media information in accordance with the present invention.
In accordance with another embodiment, the method of the present
invention controls the manner in which media information is displayed based
on the person who sent the information, Referring to Fig. 6, this method
10 begins by receiving a call in a first terminal. (Block 40). Once a call
connection has been established, a second step of the method includes
extracting and processing caller identification information in the receiving
terminal to determine the identity of the transmitting terminal and therefore of
a user who likely placed the call. (Block 41). The extracted information may
15 include any one or more of the telephone number of the second terminal, the
name of the owner of the terminal, his or her address, etc. If the terminal is
connected to the internet, this caller ID information may be comparable
information such as a website address.
A third step includes comparing the caller ID information (e.g., caller's
20 telephone number) with information stored in a memory of the first terminal.
(Block 42). The stored information may include media information which
has been pre-stored in association with the telephone number of the
transmitting terminal. The media Information may be any of the types

WO 2004/030381 PCT/KR2003/001893
16
previously mentioned, and may even correspond to a characteristic of a user
of the transmitting terminal. Alternatively, the media information may be
transmitted to the receiving terminal and stored in memory in association with
the transmitting terminal's caller ID information for later retrieval.
5 In accordance with one particularly advantageous feature of the
invention, the pre-stored media information may be an avatar which is related
to a characteristic of the user of the transmitting terminal. In the graphics
world, an avatar is understood to be an animated icon, symbol, or character
which may be used, for example, to represent some characteristic or trait of a
10 person. This characteristic may be a physical attribute of the person or may
relate to some non-physical feature. Examples of non-physical features
include a relationship one user may have with another and a user's
occupation. The avatar may also be based on one user's opinion of the other
formulated, for example, based on prior knowledge and experience.
15 A fourth step of the method includes outputting the stored media
information on the receiving terminal based on the identity of the transmitting
terminal. (Block 43). This involves retrieving the stored media information and
the displaying it for a predetermined period of time. If the media information is
a video script, for example, the script may be played until its conclusion.
20 Alternatively, if the media information is an avatar, it may be displayed
intermittently or even constantly throughout the call.
In an optional but desirable step, an avatar representing a
characteristic of the user of the transmitting terminal is displayed before the

WO 2004/030381 PCT/KR2003/001893
17
call is answered by a user of the receiving terminal. This may be
accomplished as follows.
When a call is received, an audible tone may sound to inform a user of
the receiving terminal of the incoming call. As previously discussed, the call
5 may include information which identifies the transmitting party or his terminal,
for example, based on a telephone number or website address. When this
information received, a processor of the first terminal may search a memory
to locate an avatar which corresponds to the telephone number. This avatar
may then be automatically displayed (in lieu of, for example, the transmitting
10 terminal's telephone number). The receiving terminal user may then instantly
recognize who the calling party is. For example, if the wife of a receiving
terminal user is calling, an avatar in the shape of a heart with her image may
be displayed. In another case, if an avatar indicative of an undesirable
person is displayed, the receiving terminal user has the option of not
15 answering the call.
Another optional step is to allow the user to answer the call, but then
continue to display the avatar identifying the transmitting terminal user either
intermittently or continuously throughout the call. For example, if the only
media information to be displayed during the call is a heart-shaped avatar
20 with her image, then this avatar may be displayed until conclusion of the call.
On the other hand, if streaming video or image information is to be displayed,
then the avatar may be replaced by this additional media information. If

WO 2004/030381 PCT/KR2003/001893
17
call is answered by a user of the receiving terminal. This may be
accomplished as follows.
When a call is received, an audible tone may sound to inform a user of
the receiving terminal of the incoming call. As previously discussed, the call
5 may include information which identifies the transmitting party or his terminal,
for example, based on a telephone number or website address. When this
information received, a processor of the first terminal may search a memory
to locate an avatar which corresponds to the telephone number. This avatar
may then be automatically displayed (in lieu of, for example, the transmitting
10 terminal's telephone number). The receiving terminal user may then instantly
recognize who the calling party is. For example, if the wife of a receiving
terminal user is calling, an avatar in the shape of a heart with her image may
be displayed. In another case, if an avatar indicative of an undesirable
person is displayed, the receiving terminal user has the option of not
15 answering the call.
Another optional step is to allow the user to answer the call, but then
continue to display the avatar identifying the transmitting terminal user either
intermittently or continuously throughout the call. For example, if the only
media information to be displayed during the call is a heart-shaped avatar
20 with her image, then this avatar may be displayed until conclusion of the call.
On the other hand, if streaming video or image information is to be displayed,
then the avatar may be replaced by this additional media Information. If

WO 2004/030381 PCT/KR2003/001893
18
desired, the avatar may then be redisplayed after the additional media
information concludes to provide continuous visual communication effects.
Fig. 7 is a timing diagram showing how this optional step of the
invention may be performed. In this timing diagram, the receiving terminal
5 receives 20 seconds of video streaming data. After this data concludes, an
avatar representing a characteristic of the transmitting terminal user may be
displayed. As previously discussed, this avatar may be pre-stored in a
memory of the receiving terminal, or it may have been transmitted from the
transmitting terminal and then stored in the receiving terminal memory for
10 subsequent display. Whenever the receiving terminal displays the stored
avatar image, it is not necessary to allocate communication resources.
Fig. 8 shows an example of a table entry which may be stored in a
memory of the receiving terminal for controlling the display of media
information in accordance with the present invention. This table entry may be15 a data structure derived from a personal information management (PIM)
database located within or interfaced to the receiving terminal. The data
structure preferably includes a user identification field 50 and media
information identification field 60. The user identification field may include
information identifying a user (and/or his terminal) who either has called or
20 may be expected to call the receiving terminal. The information includes the
name of a transmitting terminal user, his or her telephone number, and the
type of terminal (e.g., mobile phone, home phone, or office phone)
corresponding to the telephone number. If the user has an internet phone,

WO 2004/030381 PCT/KR2003/001893
19
the phone number field may be replaced by a website address, otherwise
known as a Universal Resource Locator (URL).
The media information identification field is stored in association with
the user identification information and may include, for example, an address
5 in either the same or an external memory in which the media information is
stored. This situation may arise, for example, when the media information is
an image file or video clip. Alternatively, or additionally, the media information
identification field may contain information defining one or more attributes of
an avatar which corresponds to the transmitting terminal user. If the avatar
10 resembles a physical likeness of this user, the following sub-fields may be
included: hair style, face model, eye glasses, body, jacket, pants, shoes,
accessories, etc. A processor of the receiving terminal may use graphics
generation software to generate the avatar for display based on the
information in these fields.
15 The media information identification field may also include an animator
indicator sub-field (AIF) which includes a plurality of bits describing the avatar.
For example, a two-bit AIF field may indicate the following:
0 0 - No avatar exists for the particular telephone number
0 1 - Composite avatar
20 10 - Composite avatar with gestures and body movement
11 - Non-composite avatar which can be accessed by the
special address field.

WO 2004/030381 PCT/KR2003/001893
20
In operation, the receiving terminal processor may access the AIF field and
generate the avatar accordingly.
The media information identification field may also include a code for
instructing the receiving terminal processor to activate audio (e.g., a bell) or
5 other visual effects. Currently existing mobile terminals typically have more
than 1 megabits of memory space which can be used to store this code along
with a plurality of table entries for controlling the display of media information
on the receiving terminal.
The table entries of the present invention may be updated, modified,
10 or otherwise maintained by connecting the receiving terminal to an external
computing system (e.g., a personal computer) via a data port, which, for
example, may be a universal serial bus (USB) port. This external system
may be loaded with software which allows it to generate custom-designed
avatars for each transmitting terminal user identified in the table. The avatars
15 may be two- or three-dimensional representations of these users, if desired.
The memory storing the table entries of the present invention may also
store a plurality of default or factory-preset avatars which may be selected to
correspond to different users. The operating software of the receiving
terminal may be written to allow these avatars to be switched, modified, or
20 deleted either automatically or in response to a receiving terminal user's
command. Avatars may be switched for display based on the telephone
number from which the transmitting terminal user is calling. For example, as
shown in Fig. 8, one user may have multiple telephone numbers. In this case,

WO 2004/030381 PCT/KR2003/001893
21
a different avatar may be displayed based on the telephone number from
which the user is calling.
Fig. 9 shows one way in which communications may take place
between two mobile terminals 70 and 80 in accordance with the present
5 invention. In this figure, terminal 70 initiated a call to terminal 80 through a
wireless network 90. When the terminal 80 receives the call, its processor
determines the identity of caller and then displays an avatar 85 in the shape
of a man which bears the likeness of caller who's name is Christopher. This
avater may have been transmitted to terminal 80 through the network or may
10 have been created by the receiving terminal user based on his/her
experience and knowledge about the caller and pre-stored in a memory of
this terminal.
Terminal 70 also displays an avatar 75, representing his/her own
desired avatar image. This avatar may be created by the transmitter terminal
15 user to portray him/herself. It may display in his/her terminal as a default
image when the terminal is on or may be transmitted over the network to the
receiver terminal as one of optional visual communication. In the example
shown, avatar 75 corresponds to a panda bear which affectionately was
selected to correspond to caller, Christophers desired representative image.
20 At the receiver terminal, the avatar 85 corresponding to caller Christopher
may not be the same avatar 75 of the caller display. If desired, avatars 75
and 85 may be displayed throughout the call session.

WO 2004/030381 PCT/KR2003/001893
22
To make the conversation more animated, one terminal transmit a
control signal to the other terminal during the call to change an attribute of an
avatar, or to replace the avatar displayed on the receiving terminal with one
either transmitted from the transmitting terminal or pre-stored in the receiving
5 terminal. A control signal of this type may, for example, cause the avatar on
the receiving terminal to display an emotion (crying, laughing, etc.) to
coincide with a mood or feeling of the transmitting terminal user. This may be
implemented, for example, by including a mood sub-field in the table entry of
Fig. 8. This sub-field may be a two-bit field for controlling the emotion on the
10 face of the avatar. Updating this field will cause the processor to
automatically change the avatar in a corresponding manner.
As previously discussed, the table in a terminal memory may include
multiple entries for the same user. This may occur, for example, when the
user has multiple phone numbers. In this case, the same avatar may be
15 displayed for all phone numbers corresponding to that user or different
avatars may be displayed, for example, depending on the number where the
user is calling from. Also, the receiving terminal may be equipped with image-
capture software that will allow a single frame (or image) from a received
video stream to be stored and subsequently displayed.
20 The present invention outperforms conventional media
communications management systems in terms of performance and
convenience to the user. For example, the invention controls the
communication of media information between terminals using fewer network

WO 2004/030381 PCT/KR2003/001893
23
resources than are conventionally required. These resources (which include
transmission bandwidth) are reduced by allowing a memory of the receiving
terminal to store media information that conventional systems must
necessarily transmit over the network. This memory may be located within
5 the receiver or externally connected to it.
The present invention allows users to control the types of media
services that they would like to receive, thereby allowing the users to control
costs and the extent of media services to be received.
The present invention also allows users to combine, or multiplex,
10 different types of media information having different transmission bandwidth
requirements within a single transmission period, thereby enhancing the
content of conversations between users for both personal and business
applications.
With the foregoing in mind, the present invention may be used to
15 implement at least the following communications scenarios.
Visual Message Initiator (Transmitter) with Real-Time,
Two-Way Video Stream Phone Capability Including Voice Conversation
Despite of the fact that many terminals today including mobile
terminals have the capability to display streaming video, many customers
20 may not want to pay high rates carriers charge for these and other
broadband services. The present invention takes this into consideration by
giving users the option to control which media services they would like to
receive. For example, during a call set-up process, a user of the transmitting

terminal may negotiate options for a video stream service with the network.
This negotiation process may be performed using an intended visual
message transmitter. An appropriate service may then be selected from
various service options.
5 Exemplary service options include:
a) full-bandwidth streaming video service (e.g., MPEG format)
b) short-time streaming video service (e.g., MPEG format)
c) Images
d) Still animation
10 e) Live Animation
If full-bandwidth streaming video is selected, the transmitting terminal
may transmit continuous video output from the camera unit in the terminal.
This may continue until for the duration of the call or until the user switches
this function off.
15 If the short-time streaming video service is selected, the transmitting
terminal may transmit a short-time streaming video script for a predetermined
time period (e.g., 20 seconds) over a network. The receiving terminal may
capture and then display the video, and in the meantime may store the script
in an internal memory or external memory. A user of the receiving terminal
20 may display this script repeatedly from an internal memory without requiring
any additional allocation of network resources. In addition, the video script
may be refreshed periodically during the call, for example, every 2 minutes.

WO 2004/030381 PCT/KR2003/001893
25
If the user selects the option for receiving images, images may be
transmitted to the receiving terminal once every predetermined time period
(e.g., every two minutes).
If the user selects the option for receiving animation, animated
5 information such as, for example, an icon may be transmitted to the receiving
terminal, for example, in the manner shown in the timing diagrams of Figs. 5
or 7. As previously discussed, this icon may be an avatar created, for
example, by the transmitting party in the form of a character, symbol, or other
graphical representation of him or herself. The avatar may be created by
10 software stored inside the transmitting terminal, or may be downloaded from
external software tools allowing the user to create his own avatar. Those
skilled in the art can appreciate that a physical resemblance is not necessary,
as the avatar may correspond to any desired graphic of the transmitting
user's choosing. A system capable of generating an avatar of this type is
15 disclosed in U.S. Patent 6,384,829, the contents of which are incorporated
herein by reference.
In addition to still avatars, the animated information transmitted in
accordance with the present invention may be live animation or a moving
avatar, one type of which is known as an animated GIF. When the avatar
20 resembles a character of some sort, its movement may cause the avatar to
appear to be speaking, moving forward and backward, laughing, crying, eyes
closing and opening, hand pointing, and etc. While in this example the
transmitting party is identified as creating and transmitting the avatar to the

WO 2004/030381 PCTYKR2003/001893
26
receiving party, those skilled in the art can appreciate that the avatar may be
stored in and subsequently displayed on the receiving terminal. In this case,
the avatar may be automatically displayed based on recognition of caller ID
information by the receiving terminal, displayed in response to a control
5 signal transmitted from the transmitting terminal to the receiving terminal,
displayed based on control information input by the receiving party himself, or
at any other time during the call session.
When displayed in response to a control signal from the transmitting
terminal, the control signal may cause different avatars to be displayed on
10 the receiving terminal, for example, to commemorate an event (e.g., a happy
birthday GIF) or to resemble an emotion or mood the transmitting party is
feeling (e.g., a GIF resembling the transmitting part with a happy face).
When displayed based on control information input the user, the
avatar sent by the transmitting user may be ignored and replaced with an
15 avatar of the receiving user's choosing. For example, if the receiving terminal
user does not like the transmitting terminal user, the receiving terminal may,
based on previously stored settings, cause an avatar of a dog to be displayed
in response to the detection of caller ID information. If desired, this avatar
may be displayed even when the transmitting party transmits no avatar to the
20 receiving terminal.
If no media service is selected, no media information may be
displayed. In this case, no extra bandwidth is allocated for visual
communications between the transmitting and receiving terminals. All these

WO 2004/030381 PCT/KR2003/001893
27
options include a simultaneous and continuous two-way voice conversation.
At the receiving terminal, a default avatar stored in the receiving terminal or a
avatar which corresponds to the caller id may be displayed.
In this exemplary embodiment of the invention, the transmitting
5 terminal user (or call initiator) may select one of the aforementioned service
options or any combination of these options to control the display of media
information during a call session. This selection may be based on his or her
desire and willingness to pay for the service desired. Generally speaking, the
higher the bandwidth requirement, the more expensive the service option.
10 Thus, live streaming video may be expected to be the most expensive and
still animation the least expensive.
Fig. 7, which has been previously discussed, shows an exemplary
scenario. To reiterate, in this scenario the call initiator sends a 20-second
short-time stream video every 2 minutes. During the first 2- minute period,
is the call initiator sends his avatar just one time if the receiving party indicates
that he want to receive the call initiator's avatar or if the transmitting party is
not sure whether the receiving terminal user has the call initiator's avatar
stored in a memory of the receiving terminal.
After the receiving terminal receives the transmitted avatar, the
20 receiving terminal may store the avatar in a receiver-accessible memory,
which may be internal or external memory. The receiving terminal can then
subsequently display the avatar at the user's discretion.

WO 2004/030381 PCT/KR2003/001893
28
In another scenario, the call initiator does not transmit any media
information. In this case, the receiving terminal user may display an avatar
created and/or selected by this user to represent the caller. This avatar may
be stored in the receiving terminal's memory and re-called as previously
5 discussed. Because the avatar was pre-stored in the receiver terminal, no
extra bandwidth allocation is required to display this avatar and thus network
resources are conserved.
Real-Time, Two-Way Video Stream Phone Communications
Including Voice Conversation for the Call Receiver
10 During a call set-up process, the network may indicate that there is a
particular service option request from the call initiator. The service options
at the receiver side can be same as for the transmitter side. Alternatively, one
of the terminals may have a different service option setting than the other, to
reflect that user's preference for either cost savings or enhanced media
15 services. In this example, the service options are the same as in the first
example.
At the receiver, the service option request sent from the transmitting
terminal is checked against the receiver's parameter settings. These settings
may indicate the current software and hardware versions of the receiving
20 terminal, and the willingness of a receiving terminal user to share the cost
of communicating or receiving media services indicated in the service option
request. If the requested services are acceptable to the receiving terminal
user, the transmitting terminal user (or call initiator) transmits the media

WO 2004/030381 PCT/KR2003/001893
29
information to the receiving terminal in accordance with the service options
mentioned in the request.
For the avatar option, the receiving terminal does not need to receive
any information from the call initiator if the avatar of the call initiator has
5 already been generated and stored in the receiver terminal's memory or PIM
database. In this case, the receiving terminal fetches and then displays the
particular avatar from the memory or PIM database based on the caller
initiator's phone number (Caller ID). This feature of the invention is
advantageous because it allows media information to be displayed on the
10 receiver terminal without using any bandwidth resources of the network.
The system and method of the present invention may include a
number of additional features. For example, the invention may communicate
media information with voice communications (e.g., video teleconferencing,
video telephone applications, etc) or without voice communications (e.g.,
15 real-time, instant messaging system, etc.). This may be accomplished, for
example, by transmitting voice signals over a circuit-switched logical channel
and the media information over one or more packet-switched logical
channels. Those skilled in the art can appreciate that other known methods
may also be used.
20 Other modifications and variations to the invention will be apparent to
those skilled in the art from the foregoing disclosure. Thus, while only certain
embodiments of the invention have been specifically described herein, it will

WO 2004/030381 PCT/KR2003/001893
