Abstract: In this article we provide a framework for controlling the bit rate of multiple prerecorded MPEG video sequences by choosing the quantization factors assigned to individual sources in a way that the total mean square error at the output of the encoder is minimized. We propose and test a knapsack model for the selection of the quantization factors. Our computations based on a set of relatively diverse video sequences reveal that the proposed model achieves a high utilization of the available bandwidth and acceptable distortion levels without any data loss.
