Coding transform coefficients in image/video encoder and/or decoders |
摘要 |
The invention relates to a method for encoding a set of data symbols comprising zero-valued data symbols and non-zero-valued data symbols that comprises assigning a codeword to represent a non-zero-valued data symbol and an associated number of preceding or following zero-valued data symbols by performing a mapping operation. According to the invention, the mapping operation by which a codeword is assigned to a non-zero-valued data symbol and its associated number of preceding or following zero-valued data symbols is dependent on a maximum possible number of zero-valued data symbols in said set of data symbols. A corresponding decoding method, as well as encoding and decoding devices are also described. |
