摘要： Context-based adapative binary arithmetic coding (CABAC), as used in video standards such as H.264/AVC, with a renormalization of the interval low value plus range that includes partitioning of the bits of the low value to provide output bits plus low value update without bit-level iterations or aggregation of output bits until a full byte can be output.
摘要翻译：基于上下文的自适应二进制算术编码（CABAC），如H.264 / AVC等视频标准中所使用的，具有区间低值加上范围的重新归一化，其包括低位值的分配以提供输出位加低值更新而不进行位级迭代或输出位的聚合，直到可以输出全字节。

摘要： Several methods and a system of multilayer encryption of a transport stream data and modification of a transport header are disclosed. An exemplary embodiment provides a method of a multilayer encryption. The method includes further encrypting an initially encrypted transport stream data to generate a multilayer encrypted data using a processor and a memory. The method also includes determining a further encryption flag data. The encryption method modifies a transport header of the multilayer encrypted data. In addition, the encryption method includes the further encryption flag data in an adapted component of a modified transport header.

摘要： Integrated circuits (290, 252, 254) and methods (500) for processing transport stream signals (2401, 2402, 2403, . . . , 240N) including broadcast program data packets (2261, 2262, 2263, . . . , 226N) containing broadcast program data and non-broadcast program data packets (318) containing non-broadcast program data. The methods involve (518) multiplexing a portion of the non-broadcast program data packets together to form a first signal (224). The methods also involve (522) processing the first signal to generate a second signal (228). This processing includes re-encrypting a portion of the non-broadcast program data to form re-encrypted non-broadcast program data. The methods further involve (524) demultiplexing the second signal to obtain at least one data packet (4221, 4222, 4223, . . . , 422N) therefrom including the re-encrypted non-broadcast program data. Thereafter, (528) the data packet and the broadcast program data packet(s) are multiplexed together to form multiplexed packet(s).
