Determination Of Set Of Candidate Transforms For Video Encoding
Abstract: The present invention is concerned with transform coefficient coding, wherein predetermined sets of transforms may be used. Embodiments of the present invention provide an encoder (10) and a decoder (20) for encoding a picture (12) into/from a data stream (14) using block-based prediction and block-based residual coding, the encoder (10) and decoder (20) supporting a set (94) of transforms for the block-based residual coding. The encoder (10) and decoder (20) are configured to determine (122) a transform candidate list (98) of transforms for a current residual block (84) out of the set (94) of transforms based on a height and a width of the current residual block (84), and to encode/decode a prediction residual (100) within the residual block (84) using one selected transform (102) out of the selectable list (98) of transforms and selectively signal/derive the selected transform (102) in/from the data stream (14).
