摘要:
A multimedia exchange server adapted to communicate multimedia information includes a multimedia gateway adapted to receive a first media from a first network and transmit a second media to a second network. The multimedia exchange server also includes a processor coupled to the multimedia gateway and adapted to provide the second media. The multimedia exchange server further includes a memory coupled to the processor and adapted to store the first media. The first media is stored in the memory for a predetermined period of time, which is greater than a buffering period.

A method of transmitting media to a client by an infrastructure device in a packet-switched network includes receiving a media stream at the infrastructure device. The method also includes determining an adaptation strategy according to at least one of one or more pieces of network information associated with the packet-switched network, one or more pieces of client information associated with the client, or one or more policies. The method further includes adapting the media stream according to the adaptation strategy to produce an output media stream.

A method of establishing a reduced setup time session through a gateway includes receiving a first capability message transmitted from the first terminal to the gateway and receiving a second capability message transmitted from the second terminal to the gateway. The method also includes processing the first capability message and the second capability message to form a third capability message and a fourth capability message. The method further includes transmitting a third capability message from the gateway to the first terminal and transmitting a fourth capability message from the gateway to the second terminal. Moreover, the method includes receiving a first request message transmitted from the second terminal to the gateway and transmitting a second request message from the gateway to the first terminal. Transmitting the second request message is performed independent of receiving the first request message. Additionally, the method includes receiving a first response message transmitted from the second terminal to the gateway and transmitting a second response message from the gateway to the first terminal. Transmitting the second response message is performed in response to receiving the first response message.

A method of providing video ringback services includes receiving, at a VRBT server, a setup message from a terminal originating a call and providing providing a first message from the VRBT server to an MSC. The method also includes establishing a communication session between the terminal originating the call and the VRBT server through the bidirectional bearer, thereafter, providing a video ringback stream from the VRBT server to the terminal originating the call, and receiving a first message from a terminal terminating the call indicating that the terminal terminating the call has answered. The method further includes providing a second message from the VRBT server to the MSC, wherein the second message is interpreted at the MSC as an indication to begin charging for a session and providing a communication path between the terminal originating the call and the terminal terminating the call.
摘要:
A method of managing media on a multimedia exchange server using a multimedia terminal includes receiving, at a multimedia exchange server, a request to establish a communication link between the multimedia terminal and the multimedia exchange server and establishing the communication link between the multimedia terminal and the multimedia exchange server. The method also includes transmitting a content management menu from the multimedia exchange server to the multimedia terminal. The content management menu includes one or more options for managing content on the multimedia exchange server. Additionally, the multimedia exchange server is adapted to respond to a receipt of an input indicating a selection of the one or more options for managing content.
摘要:
A method of providing an interactive multimedia game to a multimedia terminal in a telecommunication network includes receiving, at a multimedia exchange server, a request to establish a communication link between the multimedia terminal and the multimedia exchange server and establishing the communication link between the multimedia terminal and the multimedia exchange server. The method also includes providing, at the multimedia exchange server, a first media stream to the multimedia terminal. The first media stream is associated with the interactive multimedia game. The method further includes receiving, at the multimedia exchange server, one or more user inputs from the multimedia terminal. The one or more user inputs either control the interactive multimedia game or define a participation in the interactive multimedia game.

A method of transmitting a coded media frame comprises determining a plurality of media frame sizes including a media frame size, transmitting an element comprising the plurality of media frame sizes, and thereafter receiving an input media frame. The method also includes processing the input media frame according to the media frame size to provide a coded media frame, and transmitting the coded media frame.
摘要:
A method of removing a motion vector from a group of motion vectors used in an encoding process includes providing a list of motion vectors, selecting an initial motion vector from the list of motion vectors, and providing an intermediate motion vector using a motion vector refinement process. The motion vector refinement process uses, in part, the initial motion vector. The method also includes forming a region defined by one or more parameters associated with the initial motion vector and one or more parameters associated with the intermediate motion vector, selecting an additional motion vector from the list of motion vectors, determining that the additional motion vector points into the region, and modifying a state of the additional motion vector.
摘要:
A method for providing a multimedia service to a multimedia terminal includes establishing an audio link between the multimedia terminal and a server over an audio channel, and detecting one or more media capabilities of the multimedia terminal. The method also includes providing an application logic for the multimedia service, establishing a visual link between the multimedia terminal and the server over a video channel, providing an audio stream for the multimedia service over the audio link, and providing a visual stream for the multimedia service over the video link. The method further includes combining the video link and the audio link, and adjusting a transmission time of one or more packets in the visual stream to synchronize the visual stream with the audio stream.
摘要:
A method of reducing a call set-up time for a call between a pair of H.324-like terminals includes providing a first capability for the call, processing the first capability to form a first message, establishing a bearer channel, and transmitting the first message from the first terminal to the second terminal through the telecommunications network using the bearer channel. The first capability is associated with an initial mode of operation for the call. The method also includes receiving a second message transmitted from the second terminal to the first terminal. The second message includes a second capability associated with the initial mode of operation for the call. The method further includes determining that a conflict exists between the first capability and the second capability, resolving the conflict by modifying at least one of the first capability or the second capability, and transmitting information from the first terminal to the second terminal.
