Spatial scalability in 3D sub-band decoding of SDMCTF-encoded video
Abstract:
Techniques and tools are described for scalable video coding and decoding. For example, a 3D sub-band decoder receives video encoded using spatial-domain motion-compensated temporal filtering at a first spatial resolution. The decoder decodes at least part of the video for output at a second spatial resolution lower than the first spatial resolution. The decoder uses any of several techniques to improve performance by devoting extra computational resources to the decoding, devoting extra buffer resources to storing reference picture information, and/or considering spatial high-pass sub-band information.
