Independent temporally concurrent video stream coding

摘要

Implementations of independent temporally concurrent video stream coding may include generating a sequence of encoded frames by encoding a plurality of input frames, wherein encoding the plurality of input frames may include generating a first plurality of encoded frames based on the plurality of input frames, the first plurality of encoded frames including a first plurality of intra-coded frames and a first plurality of inter-coded frames, and independently generating a second plurality of encoded frames based on the plurality of input frames, wherein the second plurality of encoded frames includes a second plurality of intra-coded frames and a second plurality of inter-coded frames, such that the first plurality of encoded frames and the second plurality of encoded frames are temporally concurrent, and such that the intra-coded frames from the second plurality of intra-coded frames are temporally nonconcurrent with the intra-coded frames from the first plurality of intra-coded frame.

1. A method comprising:
encoding a plurality of input frames from an input video sequence, wherein encoding the plurality of input frames includes:
generating a first plurality of encoded frames based on the plurality of input frames, andindependently generating a second plurality of encoded frames based on the plurality of input frames, such that the first plurality of encoded frames and the second plurality of encoded frames are temporally concurrent, wherein encoding the plurality of input frames includes adjusting relative placement of sequential intra-coded frames among the first plurality of encoded frames and the second plurality of encoded frames such that an expected value of total distortion for the first plurality of encoded frames and the second plurality of encoded frames is minimized; and including the first plurality of encoded frames and the second plurality of encoded frames in an output.
