TRANSMITTING MULTIMEDIA TICKER INFORMATION

摘要

Transmission parameters for the transmission of at least one ticker information (ti) are transmitted during signaling of the transmission parameters for at least one multimedia data stream (mmd) for a session (S), the parameters establishing an additional logical transmission channel for the transmission of ticker information (ti), specifying the transmission protocol (RTP) and the payload type (555,666, 777,888) and inserting a source information which shows the source of the ticker information (ti). A session description protocol (SDP) embedded in a session initiation protocol (SIP) is used to describe and administer the transmission parameters. The invention allows the signaling for the additional information or ticker information (ti) to be implemented into existing network protocols for packet-oriented networks with only minor additional signaling and transmission operations.
