摘要： A traffic optimizer facilitates communication of data packets using a unicast protocol between a server and at least one of a plurality of clients through a multicast network. The traffic optimizer includes a communication processor and a packet processor. The communication processor receives both data including association data and the data packets using the unicast protocol from the server. The association data includes IP addresses of the server and IP addresses of at least one of a plurality of clients available for communication. The packet processor processes the data packets to optimize data transfer in response to an analysis of the data packets, and forwards the processed data packets to at least one of the plurality of clients at respective ones of the received IP addresses through a multicast network using the unicast protocol.

摘要： 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.
