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