Statistical Multiplexing (Associated with Time Division Multiplexed (TDM), Frequency Division Multiplexing, Statistical Multiplexing Gain, Scheduling Discipline for Fair Queuing, Orthogonal Frequency Division Multiple Access, RFH-OFDMA, Code-division multiple access, CDMA.) - Ideally this increases the efficiency of a multiplex transmission by using less channeling space. It can be done by varying the bit-rate of the transmission as well as the size of the channel.  https://en.wikipedia.org/wiki/Statistical_multiplexing
