Method for packet type classification to svc coded video bitstream, and rtp packetization apparatus and method

A method for efficient packet type classification to SVC(Scalable Video Coding) coded video bit streams, and an apparatus and a method for performing RTP(Real time Transport Protocol) packetization are provided to transmit the SVC coded video bit streams more efficiently through an IP(Internet Protocol) network such as Internet or the like. A method for packet type classification comprises: inducing temporal/spatial hierarchy relation information between respective NAL(Network Abstract Layer) units from field information defined in an NAL unit header of a scalable layer; grasping an encoding information type by applying complex scalability encoding to a hierarchy structure of SVC(Scalable Video Coding); and deciding an RTP(Real time Transport Protocol) packet type for a corresponding SVC coded video bit stream by using the grasped encoding information type and the temporal/spatial hierarchy relation information between the induced NAL units.
