Multichannel joint rate control of VBR MPEG encoded video for DBS applications
Aloke Guha, Daniel J. Reininger · IEEE Transactions on Consumer Electronics · 1994
A method to transmit multiplexed digital video that potentially allows for video quality and capacity gains over conventional constant bit-rate (CBR) transmission is described. The method uses a joint rate control algorithm that regulates the encoders during buffer congestion periods using bandwidth re-allocation and source rate control. A multichannel joint rate control algorithm is described and its performance simulated for MPEG encoded video on broadcast satellite (DBS) application. Results indicate significant capacity and/or quality gains over conventional CBR transmission methods.>
