Sep 13 '21 at 22:35 comment added Brad @awidgery Yes! It turns out this has been a thing all along. The keyword here is, "scalability". See also: en.wikipedia.org/wiki/Scalable_Video_Coding Also, it's my understanding that SHVC is to be used for Next Gen/ATSC 3.0 TV where some layers will be broadcast, with enhancement layers via internet, to save on the broadcast bandwidth will still providing the higher quality video.

Apr 27 '16 at 23:06 comment added Brad @stib I think that would require me to actually make such a codec. Math is hard. :-) Although, I could probably actually implement it in MJPEG since MJPEG already does the heavy lifting...

Apr 27 '16 at 16:39 comment added Brad @stib Segmentation would be used, similar to how it is used in HLS, so that a few seconds of video would be encoded in each chunk. You're right, each chunk of each quality stream would have to be downloaded to decode the desired quality for that chunk of time. And, the client would automatically adjust between downloading 1, 2, or 3 chunks per segment as it has bandwidth to do so. For HLS, the client decides which bitrate chunk to download, somewhat dynamically. This would be the same, except that there's 3 requests for the high quality stream instead of one.
Apr 27 '16 at 14:10 comment added stib Wouldn't the problem be that the player would have to download each stream entirely before it could play? Though I guess you could download GOPs so that you download GOP1-low, GOP1-mid, GOP1-hi, then GOP2-low, GOP2-mid etc., only downloading what you can in the time available.
