Abstract
Ensuring a long-term average bitrate for channels of a statistical multiplexing meets or exceeds a specified limit. An arbitrary target average bitrate for each of a set of channels of the statistical multiplexer is received. The long-term average bit rate for each channel of the statistical multiplexer is tracked. For each allocation cycle of the statistical multiplexer, bitrates to each encoder are assigned by splitting a bit allocation pool of the statistical multiplexer into a first portion and a second portion. The first portion is allocated to maximize video quality and the second portion is allocated to minimize a gap between the set of channels that are below their arbitrary target average bitrate based on the long-term average bit rate for the set of channels. Thereafter, the bit rates allocated from the first and second portions are distributed to the encoders encoding/transcoding the set of channels.
