A system combining extrapolated and interpolated side information for single view multi-hypothesis distributed video coding

Single view distributed video coding (DVC) is a coding method that allows for the computational complexity of the system to be shifted from the encoder to the decoder. This property promotes the use of DVC in systems where processing power or energy use at the encoder is constrained. Examples include wireless devices and surveillance. This paper extends on a previously proposed multi-hypothesis non-binary LDPC coded system by introducing an additional motion extrapolated hypothesis at the decoder. By combining interpolation and extrapolation in the side information creation process, the decoder is given access to more information. The use of extrapolation specifically improves the performance of the system over larger GOP sizes.
