Abstract
A system for bit-rate stream playout at preset speeds including a regular playout speed and other than the regular playout speed includes multiple streams encoded at a same bit-rate (R) but at a plurality of playout speeds. A selection mechanism is responsive to requests for playout speeds. The selection mechanism selects from among the plurality of streams to service a request.
