Abstract
The current interpolation based distributed video codecs get excellent rate distortion performance at the cost of high decoder complexity and delay, which make them almost impractical. An efficient way to solve the problem is to use extrapolation instead of interpolation in side information generation. The proposed codec combines the state-of-the-art optical flow based extrapolation algorithm with modulo operation based low complexity pixel domain distributed video codec and gets high R-D performance. The proposed codec enables the successful encoding and decoding of the frames, thus reducing the delay of the whole system. Simulation results show that the proposed codec outperforms other interpolation and extrapolation based codecs in a series of video sequences. Additionally, the decoding complexity is as low as 1/50 of the traditional distributed video codec without increasing the complexity of the encoder.
