N2 - The arrangement of I-picture starting times of multiplexed VBR MPEG videos may significantly affect the cell loss characteristics of superposed traffic. This paper presents a starting time selection method of a new request so that the minimum and maximum cell loss ratios (CLRs) of superposed traffic including the new request are expected. For this purpose, both single and superposed VBR MPEG video traffic are modeled as a time-varying periodic picture-type dependent rate envelope sequence. Through experiments and observations, we show that the average power of superposed VBR MPEG video traffic is a good measure for the burstiness of the traffic. The proposed starting time selection method is derived from these properties. The efficiencies of the proposed method are tested by comparison with other scheduling methods for the smoothness of the peak rate and the CLRs of the scheduled-superposed stream, and, we also provide connection admission control (CAC) methods applicable to ATM multiplexers which can manipulate the starting times of sources and video on demand (VOD) servers which can do that.
