Optimization and comparision of coding algorithms for mobile 3DTV
Different methods for coding of stereo video content for mobile 3DTV are examined and compared. These methods are H.264/MPEG-4 AVC simulcast transmission, H.264/MPEG-4 AVC Stereo SEI message, mixed resolution coding, and video plus depth coding using MPEG-C Part 3. The first two methods are based on a full left and right video (V+V) representation, the third method uses a full and a subsampled view and the fourth method is based on a one video plus associated depth (V+D) representation. Each method was optimized and tested using professional 3D video content. Subjective tests were carried out on a small size autostereoscopic display that is used in mobile devices. A comparison of the four methods at two different bitrates is presented. Results are provided in average subjective scoring, PSNR and VSSIM (Video Structure Similarity).
