The layers are formed into reference arrays that are used by a function, such as a weighted combination, to form a final prediction. The weights can be variable, chosen from among a number of number of sets of weights. The prediction is used in encoding or decoding a block of video data. The weights can be determined in a number of ways, and for a given prediction mode, the same weights, or different weights can be used for all pixels in a target block. If the weights are varied, they can depend on the distance of the target pixel from reference arrays. An index can be sent indicating which set of weights is to be used."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiple reference intra prediction using variable weights","description":"A method of performing intra prediction for encoding or decoding uses multiple layers of reference samples.
