Description: | For applications where hierarchically encoded streams are being sent to a unicast address, it may be necessary to specify multiple transport ports. This is done using a similar notation to that used for IP multicast addresses in the "c=" field: m=<media> <port>/<number of ports> <transport> <fmt list> In such a case, the ports used depend on the transport protocol. For RTP, only the even ports are used for data and the corresponding one-higher odd port is used for RTCP. For example: m=video 49170/2 RTP/AVP 31 would specify that ports 49170 and 49171 form one RTP/RTCP pair and 49172 and 49173 form the second RTP/RTCP pair. RTP/AVP is the transport protocol and 31 is the format (see below). | ||
