statistical multiplexing

[stə‚tis·ti·kəl ′məl·tə‚pleks·iŋ]
(communications)
Time-division multiplexing in which time on a communications channel is assigned to multiple users on a demand basis, rather than periodically to each user.

statistical multiplexor

In communications and networking, a device that merges several low-speed channels into a single high-speed channel and vice versa. A standard multiplexor is set up to interleave a fixed number of incoming channels at the same rate onto the outgoing channel regardless of whether every incoming channel contains data. A statistical multiplexor analyzes the incoming traffic and dynamically changes the interleaving in order to use all the available capacity of the outgoing channel.
