Title:
ブロック統合およびスキップモードをサポートする画像符号化
Document Type and Number:
Japanese Patent JP6856554
Kind Code:
B2
Abstract:
A coding efficiency increase is achieved by using a common signalization within the bitstream with regard to both activation of merging and activation of the skip mode. That is, one of the possible states of one or more syntax elements within the bitstream may signalize for a current sample set of a picture that the respective sample set is to be merged and has no prediction residual encoded and inserted into the bitstream. Alternatively speaking, a common flag may commonly signalize whether the coding parameters associated with a current sample set are to be set according to a merge candidate or to be retrieved from the bitstream, and whether the current sample set of the picture is to be reconstructed merely based on a prediction signal depending on the coding parameters associated with the current sample set, without any residual data, or to be reconstructed by refining the prediction signal depending on the coding parameters associated with the current sample set by means of residual data within the bitstream.
