Method and apparatus for digital video reconstruction

摘要

A method and apparatus for reconstructing digital video is provided. In one embodiment, a method for transmitting an original video stream including at least one frame includes segmenting the frame into a plurality of regions, encoding each region in accordance with one of a plurality of available interpolation algorithms that provides minimal distortion the region, and providing a signal containing information that enables a decoder to identify the interpolation algorithms corresponding to each of the regions. This information enables a decoder to enhance a base layer video stream while minimizing the amount of information that must be provided to the decoder in order to perform the enhancement.
