Title:
スケーラブルなマルチビュービデオコーディングにおける高度な残差予測
Document Type and Number:
Japanese Patent JP6545852
Kind Code:
B2
Abstract:
In an example, a method of coding video data includes determining, for a first block of video data in a first layer of video data, a temporal motion vector and associated temporal reference picture for predicting the first block, where the temporal reference picture has a picture order count value. The method also includes determining a disparity reference block in a disparity reference picture indicated by a disparity vector associated with the first block, and determining whether a decoded picture buffer contains a temporal-disparity reference picture in the second view and having the picture order count value of the temporal reference picture. When the decoded picture buffer does not contain a temporal-disparity reference picture in the second view and having the picture order count value of the temporal reference picture, the method includes modifying an inter-view residual prediction process for predicting residual data of the first block.
