Abstract
This paper presents a general and comprehensive analysis of major issues and difficulties in real-time DSP implementation of hybrid video coding. Methodologies for MOPS reduction of motion estimation and DCT, code optimization, task division in parallel processing, and codec adaptation are addressed. Performance of realtime H.263 and MPEG-4 video system with these techniques are demonstrated. Video object segmentation and its implementation in an MPEG-4 system are also discussed
