Abstract

This paper describes some investigation made into multi-step ahead prediction on the traffic intensity of digital video sources coded with hybrid Motion Compensation/Differential Pulse Code Modulation/Discrete Cosine Transform (MC/DPCM/DCT) method. Although current coding standards recommend constant bit rate (CBR) output by means of a smoothing buffer, the method inherently produces variable bit rate (VBR) output, and VBR transmission is necessary for high quality delivery. Prediction results presented in this paper have been obtained using a fuzzy logic scheme, and linear autoregressive (AR) algorithm is also separately used as a comparison. The proposed fuzzy prediction methods can be applied to the development of usage parameter control (UPC) and congestion control algorithms in ATM network where propagation delay is significant.
