METHOD AND SYSTEM FOR EXCHANGING INFORMATION BETWEEN MULTIMEDIA NETWORK NODES |
摘要 |
The present invention relates generally to the transmission of video, audio and/or data signals between nodes in multimedia networks, and in particular to the exchange of control information, in the form of capabilities information, between such nodes. The invention is suitable for use in the negotiation of the capabilities of nodes, notably in H.323 and SIP multimedia networks. The present invention provides a method and system of inband capability negotiation or signalling including logically mapping multimedia capabilities information to inband messages in order to establish the format for the passing of the multimedia information from the first network to the second network. The inband messages may be TFO (Tandem Free Operation) messages.
