Abstract: Multi-layered frame-compatible video delivery is described. Multi-layered encoding and decoding methods, comprising a base layer and at least one enhancement layer with reference processing, are provided. In addition, multi-layered encoding and decoding methods with inter-layer dependencies are described. Encoding and decoding methods that are capable of frame-compatible 3D video delivery are also described.

Abstract: Compression transforming video into a compressed representation (which typically can be delivered at a capped pixel rate compatible with conventional video systems), including by generating spatially blended pixels and temporally blended pixels (e.g., temporally and spatially blended pixels) of the video, and determining a subset of the blended pixels for inclusion in the compressed representation including by assessing quality of reconstructed video determined from candidate sets of the blended pixels. Trade-offs may be made between temporal resolution and spatial resolution of regions of reconstructed video determined by the compressed representation to optimize perceived video quality while reducing the data rate. The compressed data may be packed into frames. A reconstruction method generates video from a compressed representation using metadata indicative of at least one reconstruction parameter for spatial regions of the reconstructed video.
