CSP1HT based scalable video codec for layered video streaming

Abstract

A layered scalable video codec based on the 3-D Color Set Partitioning in Hierarchical Trees (3D-CSPIHT) coder is presented in this thesis. The layered codec introduces layering of encoded bit streams to support layered scalable video streaming. It restricts the significance criteria of the original 3D-CSPIHT coder to generate separate bit streams comprised of cumulative layers. Layers are defined according to resolution subbands. The layered codec incorporates a new sorting algorithm to produce (spatial) resolution/frame rate scalable bit streams, and a specially designed layer ID to identify the layer that a particular data packet belongs to. By doing so, decoding of lossy data is achieved.
