Motion Compensated Post-processing For Low Bit Rate Videoconferencing On ISDN Lines

Abstract

This paper presents a post-processing algorithm for low bit rate videoconferencing on ISDN lines. The relatively few images per second that are transmitted during low bit rate multi-media communications are up-converted after decoding inside the terminal receiver to an increased frame rate of 25 Hz or 30 Hz, depending on the display. Applying advanced motion estimation and compensation techniques can achieve a significant improvement in motion portrayal of moving objects.
