摘要： In the current high efficiency video coding development, each LCU has its own quantization parameter (QP) and the difference between a current QP and a reference QP is transmitted instead of the QP value itself. Since the LCU is much larger than the macroblock of AVC/H.264, using one delta QP per LCU may cause rate control unable to adapt to the bitrate quickly enough. Consequently there is a need to adopt delta QP in units smaller than LCU to provide more granular rate control. Furthermore, it is desirable to develop a system that is capable of facilitating more flexible delta QP. Accordingly, adaptive quantization parameter processing is disclosed where a QP minimum CU size for incorporating or deriving a delta QP is indicated selectively in the slice level or in the sequence/picture level. In one variation, the delta QP is incorporated or derived only if nonzero quantized transform coefficients exist in a leaf CU that is larger than the QP minimum CU size. In another variation, quantization parameter information is only incorporated or derived when a leaf CU has any nonzero quantized transform coefficient. In yet another variation, a flag is used to indicate whether one delta QP per LCU is transmitted if the LCU has any nonzero quantized transform coefficient or one delta QP per leaf CU is transmitted if the leaf CU has any nonzero quantized transform coefficient.
摘要翻译：在当前的高效率视频编码开发中，每个LCU具有其自己的量化参数（QP），并且发送当前QP与参考QP之间的差异而不是QP值本身。由于LCU比AVC / H.264的宏块大得多，因此使用每个LCU的一个delta QP可能导致速率控制不能足够快地适应比特率。因此，需要采用小于LCU的单位的delta QP来提供更细粒度的速率控制。此外，期望开发能够促进更灵活的delta QP的系统。因此，公开了自适应量化参数处理，其中用于合并或导出增量QP的QP最小CU尺寸在片级或序列/画面级别中有选择地表示。在一个变型中，只有当非零量化变换系数存在于大于QP最小CU尺寸的叶CU中时，才加入或推导增量QP。在另一个变型中，当叶CU具有任何非零量化变换系数时，仅结合或导出量化参数信息。在又一个变型中，如果LCU具有任何非零量化变换系数，或者如果叶CU具有任何非零量化变换系数，则发送每个叶CU，则发送每个LCU一个ΔQP是否被发送的标志。

摘要： An encryption-enabled entropy coder for a multimedia codec is disclosed. The entropy coder implements a randomized Huffman coding scheme without storing multiple sets of Huffman tables in a ROM. The entropy coder includes a ROM storing a single set of code tables, a table lookup section coupled to the ROM which converts symbols to original codewords and vice versa by performing table lookup, and a table randomizer section for converting original Huffman codewords to randomized Huffman codewords and vice versa using an isomorphic code generator algorithm. The table randomizer section performs the conversion based on a key hopping sequence generated by a pseudorandom bit generator using an encryption/decryption key.
