Methods and devices for pipelining within binary arithmetic coding and decoding |
摘要 |
Methods of encoding and decoding for video data are described for encoding or decoding multi-level significance maps whilst enabling pipelining of the BAC engine. In one example, coefficient groups are redefined to remove the significant-coefficient flags of the first and last position of a block and replace them with significant-coefficient flags of the last position in the previous block and the first position in the next block. A modified scan order is applied to each coefficient group. In another example, the coefficient groups remain block-based, but the scan order is modified to interleave the encoding and decoding sequential coefficient groups. |
