Abstract :
Distributed Video Coding (DVC) is a relatively new video coding paradigm evolved for catering to emerging applications such as wireless video surveillance and streaming. DVC is not yet commercially deployed due to various challenges including necessity of feedback channel, unavailability of standardized complete coding method including chroma components handling, lower Rate Distortion (RD) performance and flicker. The DVC architectures developed so far assumed availability of feedback channel and dealt with luma component only. In this paper colour components (chroma) coding method of feedback-free DVC is proposed and results are presented.
