Statistical multiplexing is a proven technique used to dynamically assign compression bitrates based upon video complexity and motion requirements of individual channels. The principle of statistical multiplexing is that a group or "Pool" of encoders shares a fixed quantity of bandwidth. The bandwidth is allocated on a frame by frame basis by a centralized controller (multiplexer) so the encoder with the most complex video is allowed to borrow more bandwidth from the pool of encoders with less difficult video.
