摘要： A method of delivering a video ringback media stream to a first terminal includes transmitting a session signaling message from the first terminal to a ringback server, transmitting a session signaling response message from the ringback server to the first terminal, and establishing one or more channels between the ringback server and the first terminal. The method also includes establishing one or more media streams between a content device and the ringback server and processing the one or more media streams in the ringback server to form a video ringback media stream. The method further includes transmitting the video ringback media stream from the ringback server to the first terminal, transmitting a second session signaling message from the ringback server to a second terminal, and transmitting a second session signaling response message associated with answering a call from the second terminal to the ringback server. Transmitting the second session signaling response message is performed after transmitting a session signaling response message.

摘要： A method and apparatus for frame classification and rate determination in voice transcoders. The apparatus includes a classifier input parameter preparation module that unpacks the bitstream from the source codec and selects the codec parameters to be used for classification, parameter buffers that store previous input and output parameters of previous frames, and a frame classification and rate decision module that uses the source codec parameters from the current frame and zero or more frames to determine the frame class, rate, and classification feature parameters for the destination codec. The classifier input parameter preparation module separates the bitstream code and unquantizes the sub-codes into the codec parameters. The frame classification and rate decision module comprises M sub-classifiers and a final decision module. The characteristics of the sub-classifiers are obtained by a classifier construction module, which comprises a training set generation module, a learning module and an evaluation module.

摘要： A method of processing a call with reduced call set-up times using one or more telecommunication networks includes providing one or more preferences for a call associated with a first terminal and a second terminal. The one or more preferences are associated with an initial setup of one or more media channels for the call. The method also includes processing the one or more preferences as a preference message, processing the preference message by an FEA procedure to provide an FEA preference message, and transferring a first framing synchronization flag sequence, the FEA preference message, and a second framing synchronization flag sequence from the first terminal to the second terminal. The method further includes receiving one or more acknowledgement preference messages from the second terminal, completing the initial setup of the one or more media channels, and thereafter, exchanging information between the first and second terminals.

摘要： Methods of establishing multimedia telecommunication (a multimedia “call”) between equipment (“terminals”). More particularly, the invention provides methods for reducing the time required to establish calls between terminals that implement the ITU-T H.324 Recommendation and other Standards and Recommendations derived from or related to this such as the 3G-324M recommendation developed and adopted by the Third Generation Partnership Projects (3GPP and 3GPP2). More specifically, it relates to (i) a method and apparatus for concatenating the H.245 messages that are required to pass between the terminals at the start of the call to establish the capabilities of both terminals and agree on the type and format of media and data to be exchanged (ii) a method and apparatus for using non-standard H.245 messages or standard H.245 messages with non-standard fields to accelerate such establishment and (iii) a method and apparatus of informing each terminal of the capabilities of the other and proposing the type and format of media and data to be exchanged by means of any user-defined fields that are inserted in the call signaling protocol that is used for bearer establishment prior to the start of the H.324 stage of the call.

摘要： A method for handling video bitstream errors in a multimedia gateway device wherein a gateway device detects errors in the incoming video bitstream and sends a signal to the originating device to refresh the bitstream without need of error detection from an end terminating device. When the terminating device signals for the video bitstream to be refreshed, the gateway locally generates and transmits an appropriate refresh frame. The invention allows the gateway to handle errors for devices such as streaming and message servers that have no built-in error handling.
