Abstract

From a layered DCT coding approach, this work introduces a two-dimensional Markov model that captures realistically the time-varying character of the video transmission process and develops a rate control mechanism that helps decisively either in increasing bandwidth utilization or improving the quality of transmitted video under the constraint of least available access rate. This property is not apparent in conventional systems that depend simply on reservation of extra capacity in order to cope with the time-varying nature of channel capacity requirements of video signals
