Frame compatible formats for 3D video distribution

Stereoscopic video will soon be delivered to the home through various channels. To make this feasible for some channels, the representation of the stereo video is modified to accommodate certain constraints on legacy systems. Among the various constraints that must be considered include the capabilities of production equipment and transmission infrastructure, as well as existing receivers and uncompressed digital interfaces between devices within the home. This paper outlines the typical constraints that are encountered in these domains and provides an overview of the various frame-compatible formats that are being considered for distribution of 3D video through such legacy systems. The benefits and drawbacks of these formats are discussed and the current status in various industry forums is reviewed.
