This paper proposes a unidirectional encoder rate control (ERC) scheme in the interpolation based distributed video coding. As the encoder is complexity constrained, accurate estimation of number of bits to decode each bit plane is indeed difficult at the encoder. In case of under-estimation of the bits, correction of the errors in the decoded bit planes, by utilizing the available information, is...
Iterative source-channel decoding (ISCD) exploits the residual redundancy of source codec parameters by using the Turbo principle. However, ISCD might require more computational complexity than available. The main reason is that the utilized soft decision source decoder (SDSD) can be computationally quite expensive. In this paper we propose a joint source-channel coding approach which reduces the...
Distributed video coding (DVC) technology is investigated and payed more and more attentions in wireless video applications because of characteristics of its encoder with low-complexity and decoder with high-complexity. Its coding types can be sorted the key and Wyner-Ziv frames, key frames are with conventional intra-coding mode, Wyner-Ziv frames are coded by an encoder that is composed of quantizer...
