Video signal encoding apparatus.

摘要

In digital video signals differing in the number of pixels, such as a standard video signal with the screen aspect ratio of 4:3 and a wide video signal with the aspect ratio of 16:9, the data quantity after encoding is equalized without increasing the compression ratio of the video signal greater in the number of pixels. An encoding apparatus performs intraframe encoding of the standard video signal so that the coded data quantity is constant in every frame, and interframe encoding of the wide video signal in each two frames so that the coded data quantity is constant in every two frames.
