The appearing of heterogeneous network scenarios, where mobile communications play a significant role, has introduced the need of dealing with a higher percentage of losses and errors with respect to the traditional wired communications. The increased amount of losses occurring during video transmissions makes the traditional video coding techniques inadequate and requires the design of robust schemes that provide a high Quality-of-Service (QoS) to the end user.
A recently proposed class of coders apply the principles of Distributed Source Coding (DSC) to video coding. The designed encoders enable a robust coding of visual information requiring a limited complexity.
However, these DSC-based video encoders have been unable to reach a compression efficiency comparable to that of motion-compensated predictive coding based video codecs, such as H.264/AVC. This motivates us to focus on the investigation of efficient models for video data in order to improve the compression gain.
Such a DSC-based, compression-centric encoder is an important block towards building a robust DSC-based video coding framework.
