VIDEO COMPRESSION DEVICE AND A METHOD FOR COMPRESSING VIDEO

摘要

A method of implementing a bit-rate reduction process for compressed digital video data (fig.5), to further reduce the video bit rate requirements without adversely affecting the visual quality is described. The bit rate reduction (fig.5) is achieved by adaptively modifying the effective frame rate. It is affected by dropping suitable frames, or parts thereof, an replacing them with duplicating frames (512). The selection of frames to replace can be based on motion analysis (505).
