Development and optimization of coding algorithms for mobile 3DTV

Error resilience tools for H.264/AVC are presented. Slice encoding has been implemented in the H.264/MVC reference software JMVC 5.0.5. An evaluation of the new encoder shows that the additional bit rate needed for the error resilience can be neglected for error free channels. In case of error-prone channel the new slice mode provides sufficient error resilience. The Mixed Resolution Stereo Coding (MRSC) approach has been evaluated. The optimal bit rate distribution between left and down sample right view has been examined. The Advanced Mixed Resolution Stereo Coding (AMRSC) approach has been developed. The three main features of AMRSC are optimized down sampling, interview prediction and view enhancement using unsharp masking. The suitability of sub sampling and low pass filtering together with interview prediction has objectively been evaluated. Further improvements of coding efficiency have been achieved by optimizing the bit rate distribution between the full view and the predicted down-sampled view. AMRSC is compliant with the overall MVC coding strategy in Mobile3DTV. For subjective evaluation of coding methods 96 test stimuli have been generated from the six sequences of the coding test set using Simulcast, Multi View, Mixed Resolution and Video + Depth coding. Two codec profile and a low and a high quality level have been used. 24 test stimuli have been generated for subjective evaluation of transmission approaches using Simulcast, Multi View and Video + Depth coding. Half of the 24 sequences have been coded using the new encoder supporting error resilience methods.
