- W2318693757 abstract "Coding control schemes are developed for store-and-forward video codecs which transmit high quality pictures through low bit rate digital lines. Video transmission through easily accessable digital networks, such as ISDN and INMARSAT-A HSD service is in demand. The current transmission rates, however, are around 64 kbit/s, and are not sufficient for real-time transmission of high quality video sequences. The store-and-forward video coding approach solves this problem by using rate conversion at the expense of transmission time. Here, new techniques are required for coding rate and quality control.This paper describes a coding rate control scheme that can be used to improve coding efficiency under variable bit rate conditions. It also describes an adaptive pre-filter that optimizes input picture resolutions as well as an edge-preserving post-filter that reduces block noise for subjective quality improvement. Each scheme is evaluated by computer simulation." @default.
