Abstract
Methods, systems, mediums, and devices use video processing with low latency bitstream distribution.
Claims17
An apparatus comprising:
- memory;
- computer readable instructions;
- and
- at least one processor circuit to be programmed based on the computer readable instructions to:
- access a first bitstream of a video sequence of encoded frames provided in a base layer and at least one enhancement layer of the first bitstream, the at least one enhancement layer having a higher resolution than the base layer, the encoded frames corresponding to groups of pictures, an individual group of pictures (GOP) of the groups of pictures (GOPs) to have no inter-prediction frame dependencies to other GOPs, and the individual GOP to have at least one sub-GOP that (i) has no inter-prediction dependencies to frames of another sub-GOP in the individual GOP, (ii) depends from a first I-frame of the GOP, and (iii) begins with an anchor frame that is not an I-frame;
- and
- select the encoded frames of a current GOP to be packed into a second bitstream to be transmitted to a remote device, the second bitstream having frames provided in a base layer and at least one enhancement layer of the second bitstream, the selection to omit the encoded frames from the first bitstream between the first I-frame of the current GOP and a selected sub-GOP of the current GOP, the base layer of the first I-frame in the second bitstream.
4 more elements
A computer-implemented method comprising:
- accessing a first bitstream of a video sequence of encoded frames, the encoded frames based on groups of pictures, an individual group of pictures (GOP) of the groups of pictures (GOPs) having no inter-prediction frame dependencies to other GOPs, and the individual GOP having at least one sub-GOP that has (i) no inter-prediction dependencies to frames of another sub-GOP in the individual GOP, (ii) depends from a first I-frame of the GOP, and (iii) begins with an anchor frame that is not an I-frame;
- and
- selecting the encoded frames of a current GOP to be packed into a second bitstream to be transmitted to a remote device, the selecting to omit the encoded frames from the first bitstream between the first I-frame of the current GOP and a selected sub-GOP of the current GOP, the first I-frame and an anchor frame of the selected sub-GOP to be a first two frames of the second bitstream, and the first I-frame (i) is to be used as a reference frame of the anchor frame and (ii) is not to be displayed at the remote device.
At least one non-transitory computer-readable medium comprising instructions to cause a computing device to at least:
- access a first bitstream of a video sequence of encoded frames provided in a base layer and at least one enhancement layer of the first bitstream, the at least one enhancement layer having a higher resolution than the base layer, the encoded frames based on groups of pictures, an individual group of pictures (GOP) of the groups of pictures (GOPs) to have no inter-prediction frame dependencies to other GOPs, and the individual GOP to have at least one sub-GOP that (i) has no inter-prediction dependencies to frames of another sub-GOP in the individual GOP, (ii) depends from a first I-frame of the GOP, and (iii) begins with an anchor frame that is not an I-frame;
- and
- select the encoded frames of a current GOP to be packed into a second bitstream to be transmitted to a remote device, the second bitstream having frames provided in a base layer and at least one enhancement layer of the second bitstream, the selection to omit the encoded frames from the first bitstream between the first I-frame of the current GOP and a selected sub-GOP of the current GOP, the base layer of the first I-frame in the second bitstream.
