ABSTRACT:
In a RTP stream having a plurality of FEC frames containing source blocks of media packets, random access points are inserted in front of the source blocks so as to allow a media decoder to decode the media packets as soon as FEC decoding is finished. In particular, the media packets contain forward error correction (FEC) source blocks for a multimedia broadcast/multicast-based streaming service content. As the multimedia broadcast/multicast streaming service includes dynamic interactive multimedia scene content where the source RTP packets of different media along with the FEC RTP packets are transmitted as separate RTP streams, the inclusion of the random access point facilitates immediate rendering of the dynamic interactive multimedia scene content after FEC decoding, thus reducing the tune-in latency.
