Title
4-Psk Ttcm For Wyner-Ziv Frame Coding In Dvc
Abstract
This paper proposes a novel approach for the implementation of Distributed Video coding (DVC) using 4-PSK turbo trellis coded modulation (TTCM). We have adapted the TTCM concept for source coding by generating parity at the encoder and transferring the symbol mapping to the decoder. The parity bits are sent to the decoder with puncturing as in a turbo based DVC codecs and combined with side information to form the symbols used in the TTCM decoder. The side information is generated by basic frame interpolation. The proposed codec was tested with different test video sequences and the results obtained show up to 6 dB improvement in PSNR with less memory for the same bit rate when compared with the turbo coding based DVC codecs.
