Abstract

The variable bit rate concept has been converted in one of the mean topics in the study of coding algorithms for packet video. These algorithms are strongly dependent on the characteristics of the ATM network. In that sense, a quasi-variable bit rate coding scheme for packet video, based on some modifications of the codec in CCITT Rec.H.261 is presented in this paper. The proposed solution consists in giving the codec the possibility of switching the p value for each case, adequating it to the minimum value, with the condition that the quality of the coded sequence is maintained. After a full description of the introduced modifications, the results of the simulations obtained with the proposed model and several standard sequences will be done.
