ABSTRACT
Distributed Video Coding (DVC) is a coding paradigm
that gives the decoder the task to exploit the source
statistics to achieve efficient compression. Current
approaches to DVC rely on motion-compensated
interpolation to generate at the decoder an estimation of
the frame being decoded. This paper presents an iterative
motion-compensated interpolation technique that takes
advantage of all available information about the frame
being estimated, not only the previous and posterior
frames as is common practice. Simulation results show
that the addition of this estimation technique to an
