Abstract

Video conversion technology, in which a first stream of video content is accessed and multiple, different layers are extracted from the first stream of the video content. Each of the multiple, different layers are separately processed to convert the multiple, different layers into modified layers that each have a higher resolution. The modified layers are reassembled into a second stream of the video content that has a higher resolution than the first stream of the video content.
