Scalable video coding (SVC) has been standardized as an extension of the H.264/AVC standard. This paper proposes a practical real-time transport protocol (RTP) packetization scheme to transport SVC vi deo over IP networks. In combined scalabilityof SVC, a coded picture of a base or scalable enhancement layer is produced as one or more vid eo layers consisting of network abstraction layer (NAL) units. The S VC NAL unit header contains a (DID, TID, QID) field to identify the association of each SVC NAL unit with its scalable enhanceme nt layer without parsing the payload part of the SVC NAL unit. In thi s paper, we utilize the (DID, TID, QID) information to derive hierarchic al spatio-temporal relationship of the SVC NAL units. Based on the derivation using the (DID, TID, QID) field, we propose a pr actical RTP packetization scheme for generatingsingle RTP sessions in unicast and multicast transport of SVC video. The experimental results indicate that the proposed packetization scheme can be efficiently applied to transport SVC video over IP networks with little induced delay, jitter, andcomputational load.
