Abstract
Adapting characteristics of a video stream. A source video stream is received comprising instructions to employ at least one reference frame at a video adaptation device, wherein the source video stream is encoded. The source video stream is adapted, at the video adaptation device, such that the instructions are adapted to store a different number of reference frames. A video stream is produced with the different number of the reference frames.
Claims19
A method for adapting characteristics of a video stream, the method comprising:
- receiving, at a video adaptation device, a source video stream comprising instructions to employ at least one reference frame, wherein said source video stream is encoded;
- adapting said source video stream, at said video adaptation device, such that said instructions are adapted to employ a different number of reference frames, wherein said source video stream is only partially decoded before said adapting;
- and
- producing an output video stream, at a video adaptation device, with said adapted instructions to employ said different number of said reference frames, wherein said producing does not require complete re-encoding.
A system for adapting a video stream, said system comprising:
- a receiver configured to receive a source video stream comprising instructions to employ at least one reference frame wherein said source video stream is encoded;
- a video adaptation device configured to adapt said source video stream such that said instructions are adapted to employ a different number of reference frames, wherein said source video stream is only partially decoded before being adapted;
- and
- a producer configured to produce an output video stream with said different number of said reference frames, wherein said producer is not required to perform complete re-encoding to produce said output video stream.
A non-transitory computer-usable storage medium having instructions embodied therein that when executed cause a computer system to perform a method for adapting a video stream, said method comprising:
- receiving a source video stream comprising instructions to employ at least one reference frame, wherein said source video stream is encoded;
- adapting said source video stream such that said instructions are adapted to employ a different number of reference frames, wherein said source video stream is only partially decoded before said adapting;
- and
- producing an output video stream with said adapted instructions to employ said different number of said reference frames, wherein said producing does not require complete re-encoding.
