Source and channel coding recipes for mobile 3D television
The paper overviews the transmission chain of 3D television for mobile services with special emphasis on stereoscopic video transmission. Specifically, methods for source and channel coding are overviewed for their suitability for such applications. They are analyzed in terms of performance and complexity as well as in terms of user acceptance and satisfaction. Furthermore, viewing conditions involving mobile auto-stereoscopic displays are analyzed emphasizing the limitations of those displays, such as accommodation-convergence rivalry and inter-view cross-talk along with corrective measures such as anti-aliasing filtering and comfort zone maintenance. Extensive subjective tests studying the importance of visual 3D cues on portable displays and visibility of artifacts are presented. Thus, the visualization conditions are put against the processing methods in order to prescribe practical optimal selection of source-channel coding methods.
