H.26L/JVT coding network abstraction layer and IP-based transport
Thomas Stockhammer, Miska M. Hannuksela, Stephan Wenger · Proceedings - International Conference on Image Processing · 2003
The JVT/H.26L video coding scheme conceptually consists of a video coding layer (VCL) responsible mainly for coding efficiency and a network abstraction layer (NAL) that supports video specific transport features for a variety of networks. This paper describes the H.26L/JVT NAL in general, including the parameter set concept and the transport over packet-based and bit-stream oriented networks. Encapsulation of coded video data to RTP/UDP/IP transport is discussed, and applications of H.26L in fixed and wireless IP-based transmission environments are presented.
