Abstract
Distributed Video Coding (DVC) is a popular topic in the research community and the past years have seen several different implementations. DVC has been proposed as a solution for applications that have limited battery resources and low hardware complexity, thus necessitating a low complexity encoder. An ideal application would be in remote surveillance/monitoring or live video conferencing. However, current solutions use iteratively decodable channel codes like LDPCA or Turbo codes that have large latencies. In order to make real-time communication possible. The proposed architecture makes efficient use of Skip blocks to reduce the bitrate, eliminates the iterative decoding nature of the Wyner-Ziv (WZ) channel and uses a simple data-hiding based compression algorithm. This drastically cuts down on the time complexity of the decoding procedure while still maintaining an rate-distortion performance better than that of H.264/AVC Intra coding and other current DVC solutions.
