本发明之实例技术描述用以判定在视频编码及视频译码期间使用的转变。一视频编码器及一视频译码器可选择各自识别一或多个候选转变之转变子集。该视频编码器及该视频译码器可自该等经选择的转变子集判定转变。

Example techniques are described to determine transforms to be used during video encoding and video decoding. A video encoder and a video decoder may select transform subsets that each identify one or more candidate transforms. The video encoder and the video decoder may determine transforms from the selected transform subsets.
