| 主权项 | 1. 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. | ||
