A low cost wireless video transmission network with padding-based distributed video coding

Study for Distributed Video Coding Architectures

“…The proposed DVC architecture, which is referred to as PB Based DVC [8]- [10], implements a codec that is quite different from current DVC architectures. The proposed solution does not use the traditional DVC frame based design and error correction coding as the WZ frame coding, but uses a block based design and the padding algorithm.…”

“…It is very suitable for some emerging applications where computational power is sparse at encoder, such as wireless low power video surveillance, visual sensor networks, disposable camera, and mobile camera phone. Currently, there are five major groups for the development of conventional DVC architectures, viz., the Stanford Wyner-Ziv (WZ) video coding [3], Europe DISCOVER (DIStributed COding for Video sERvices) [4,5] architecture, Taiwan University's hybrid DVC(hybrid distributed video coding with frame level coding mode selection) architecture [6], the Berkeley PRISM (Powerefficient, Robust, hIgh-compression, Syndrome-based Multimedia coding) [7] architecture, and the proposed Padding Block Based Distributed Video Coding (PB Based DVC) [8]- [10]. In this paper we would have a complete description for these architectures.…”

An H.264/AVC Based Distributed Video Coding Paradigm with Mode Decision at Decoder

“…That is why the proposed transferring the heavy complexity algorithm, mode decision (MD), from encoder to decoder, thus, the computational complexity and hardware cost of the DVC encoder can be reduced greatly but maintain performance. Therefore, in this paper we propose a new DVC paradigm, improving the early proposed Padding Block Based Distributed Video Coding (PB Based DVC) [8]- [11], which has been transferred motion estimation form the encoder to the decoder, and now furthering improved MD algorithm also be transferred to the decoder. This paper is organized as follows.…”
