Each of the layers for a given block is a rendition of that block, and each of the masks distinguishes pixels of the respective layer that are relevant in reconstructing the block from pixels that are not. The encoder applies lossy compression to each of the layers and transmits the lossily compressed layers and a set of the masks to a decoder, such that the decoder may reconstruct the respective block from the layers and the mask(s)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Layer-based video encoding","description":"A technique for encoding a video signal generates multiple layers and multiple corresponding masks for each of a set of blocks of the video signal.
