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.
Claims20
A system for bit-rate constrained stream playout at preset speeds including a regular playout speed and other than the regular playout speed, comprising:
- multiple streams encoded at a same bit-rate (R) but at a plurality of playout speeds;
- and
- a selection mechanism responsive to requests for playout speeds, the selection mechanism selecting from among the plurality of streams to service a request.
A method for bit-rate constrained stream playout at preset speeds including a regular playout speed and other than the regular playout speed, comprising:
- encoding multiple streams at a same bit-rate (R) but at a plurality of playout speeds;
- and
- selecting, responsive to a request for a playout speed, from among the plurality of streams to service the request.
A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program when executed on a computer causes the computer to perform bit-rate stream playout at preset speeds including a regular playout speed and other than the regular playout speed, comprising:
- encoding multiple streams at a same bit-rate (R) but at a plurality of playout speeds;
- and
- selecting, responsive to a request for a playout speed, from among the plurality of streams to service the request.
