Method and device for processing prediction information for encoding or decoding at least part of an image

摘要

A method of processing prediction information for encoding or decoding at least part of an image of an enhancement layer of video data, the video data including the enhancement layer and a base layer, the enhancement layer being composed of processing blocks and the base layer being composed of elementary units each having associated prediction data, the method comprising for a processing block of the enhancement layer: obtaining prediction data of at least a co-located elementary unit of the reference data, the prediction data defining first predictors; and generating, from said prediction data obtained, further predictors for prediction of the current processing block.

1. A method of processing prediction information for encoding or decoding at least part of an image of an enhancement layer of video data, the video data including the enhancement layer and a base layer, the enhancement layer being composed of processing blocks and the base layer being composed of elementary units each having associated prediction data defining at least one predictor for prediction of the elementary unit, the method comprising for a processing block of the enhancement layer:
obtaining prediction data of at least a co-located elementary unit of the reference data, the prediction data defining first predictors; and generating, from said prediction data obtained, further predictors for prediction of the current processing block, wherein the prediction data comprises motion data indicative of the location of the corresponding predictor in the video data; and in the case where the motion data is bidirectional comprising two motion data sets, the method comprising generating at least one set of unidirectional motion data from the bidirectional motion data for the further predictors.
