UNBIASED ROUNDING FOR VIDEO COMPRESSION

摘要

Unbiased rounding of unsigned data is employed in the decoding or the encoding and decoding of digital bitstreams representing data-video when the video is encoded at a first bit depth and is decoded at a second bit depth, lower than the first bit depth. The unbiased rounding may be employed in processing that employs a prediction loop. When the data-compressed video is represented in frames, the unbiased rounding may be of inter-frame and/or intra-frame data.
