MULTIPLEXED VIDEO STREAMING

摘要

A plurality of video streams are transmitted over a transmission link. At intervals, one chooses for each stream an encoder setting (e.g. so that each stream is sent at the same picture quality) such that the sum of the bit rates generated by encoding the streams shall not exceed the capacity of the link. One determines for each stream, having regard to the amount of data buffered at a receiver for that stream and to the minimum bit rate needed to transmit the remainder of that stream at the chosen encoder setting, the time at which that bit rate ceases to be needed. Any surplus capacity of the transmission link is allocated to that stream that has the earliest such time.
