Abstract:
An apparatus encodes a video signal for providing a scalable video coded (SVC) signal comprising a base layer video coded signal and an enhancement layer video coded signal, wherein the base layer video coded signal has more random access points, e.g., Instantaneous Decoder Refresh (IDR) slices, than the enhancement layer and in those access units where the enhancement layer has an IDR slice, the base layer has a non-IDR slice. Transmission of the SVC occurs in packet form using the Real-time Transport Protocol (RTP) such that non-random access point slices are conveyed in Simple Time Aggregation Packets (STAP), each Simple Time Aggregation Packet comprising a Payload Content Scalability Information (PACSI) Network Abstraction Layer (NAL) Unit.
