(EN) DATA SCRAMBLING METHOD AND SCRAMBLING APPARATUS

(ZH) 一种数据加扰方法和加扰装置
Abstract
(EN) A data scrambling method and scrambling apparatus. In the data scrambling method, the scrambling apparatus can scramble a data stream containing a first data block and a second data block. The first data block and the second data block can belong to the same data sub-stream, and can also belong to different data sub-streams. When the first data block and the second data block belong to the same data sub-stream, a specification of the data stream is different from a specification of the data stream when the first data block and the second data block belong to different data sub-streams. Therefore, a scrambling apparatus can scramble data streams with different specifications.
(FR) L’invention concerne un procédé et un appareil d'embrouillage de données. Dans le procédé d'embrouillage de données, l'appareil d'embrouillage peut embrouiller un flux de données contenant un premier bloc de données et un second bloc de données. Le premier bloc de données et le second bloc de données peuvent appartenir au même sous-flux de données ou à différents sous-flux de données. Une spécification du flux de données est différente selon que le premier bloc de données et le second bloc de données appartiennent au même sous-flux de données ou à différents sous-flux de données. Par conséquent, un appareil d'embrouillage peut embrouiller des flux de données ayant différentes spécifications.
(ZH) 一种数据加扰方法和加扰装置。在数据加扰方法中,加扰装置可以对包含第一数据块和第二数据块的数据流进行加扰。第一数据块和第二数据块可以属于相同的子数据流,也可以属于不同的子数据流。当第一数据块和第二数据块属于相同的子数据流时数据流的规格不同于当第一数据块和第二数据块属于不同的子数据流时数据流的规格。因此,加扰装置可以对不同规格的数据流进行加扰。
