Abstract:
1. A method for determining a packet type for a Scalable Video Coded (SVC) video bitstream, comprising the steps of: a) deriving temporal and spatial hierarchy information of Network Abstraction Layer (NAL) units from field information defined in the NAL unit headers of scalable layers; b) detecting the type of encoding information by applying combined scalability encoding to the hierarchical structure of the Scalable Video Coding (SVC); c) determining a Real-time Transport Protocol (RTP) packet type for the corresponding SVC video bitstream by using the derived temporal and spatial hierarchy information of the NAL units and the detected type of encoding information; and d) determining an encoding order for screens in the SVC video bitstream based on field information in the NAL unit headers, and wherein Single-Time Aggregation Packet-A (STAP-A) packet types are applied to several NAL units of scalable layers that are aggregated as one within a range that does not exceed a maximum transmission unit (MTU) size.
