Abstract
In nowadays distributed video coding systems, side information is generated at the decoder using motion estimation. Therefore, the high computational complexity is swaped from the encoder to the decoder. In order to reduce the computational complexity at the decoder, generating the side information using extrapolation may be a compromise, but it brings a drawback of rate-distortion performance. To compensate this drawback, we proposed an Adaptive Distributed Video Codec (ADVC) based on multilevel coset codes. In our implementation, the temporal similarities among successive frames can be exploited substantially, and the side information is available at the encoder that achieves more accurate correlation. The simulation results show the proposed ADVC has a better rate-distortion performance than non-adaptive distributed video codec (DVC), especially in low-rate scenarios . ...
