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. The 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 an ATM network where propagation delay is significant
