Patent ID: 8582644

Claim:
A method for transmitting a video signal comprising: selecting a first scalable layer of a scalable video coded signal as a channel change layer; the first scalable layer having an associated dependency_id value that is less than an associated dependency_id value of a second scalable layer of the scalable video coded signal; and transmitting the scalable video coded signal in packet form using a Real-time Transport Protocol such that non-random access point slices are conveyed in Simple Time Aggregation Packets, each Simple Time Aggregation Packet comprising a Payload Content Scalability Information Network Abstraction Layer Unit, wherein the transmitting step includes: setting a DID field of the Payload Content Scalability Information Network Abstraction Layer Unit to a lowest value of the dependency_id value of the remaining Network Abstraction Layer Units in the respective Simple Time Aggregation Packet; and setting an RR field of the Payload Content Scalability Information Network Abstraction Layer Unit to a highest value of the dependency_id value of the remaining Network Abstraction Layer Units in the respective Simple Time Aggregation Packet.
