Abstract

Distributed video coding (DVC) has been featured by exploiting the video statistics, partially or totally at the decoder. Wireless sensor networks are supposed to have lesser complexity encoders at the expense of higher decoder complexity. Therefore DVC is more suitable to video transmission over wireless sensor networks compared to conventional video coding. Current research work on DVC is conducted for lossless channel, i.e, parity bit stream is not influenced by noise or distortion and further correlation noise due to the residual between input video frame and side information is not estimated effectively. In other words , noisy environment is not analyzed with DVC codec in recent research works. In this paper, DVC codec is enabled with the effect of AWGN noise and further a single wireless fading channel (SISO) is considered. The correlation noise is analyzed for Foreman and Carphone video sequences and relationship of correlation of adjacent key frames are discussed.
