摘要： A configuration is implemented that converts MMT format data to MPEG-2 TSV format data for recording onto medium, thereby permitting copy control in compliance with the initial copy control information. MMT format data with copy control information set therein is input and converted to MPEG-2 TS format data for re-cording onto information recording medium. The copy control information recorded in the service description table (MH-SDT) stipulated by the MMT format is acquired and, in accordance with predetermined conversion rules, used to generate the copy control information for recording to the program map table (PMT) stipulated by the MPEG-2 TS. For example, the EPN and CCI values to be recorded to the PMT are determined in accordance with the conversion rules.

摘要： A configuration is realized in which block encryption MMT format data is reproduced by applying a time stamp. An MMT format stream file and a reproduction control information file are generated and recorded in a medium. The stream file includes encryption block data to which an encryption key generated by using an additional header in which copy control information of a block unit is stored, as a seed, is applied, and the additional header. Position identification information capable of determining a position of reproduction data, a position of the seed to be applied to decoding of the reproduction data, a position of the time stamp, and a position of the seed to be applied to decoding of the time stamp is recorded in the reproduction control information file. Data decoding, and reproduction to which the time stamp is applied are performed by using recording information.

摘要： A configuration capable of recording MMT format data on a medium as BDAV format data and performing copy control according to the original copy control information is achieved. The MMT format data, for which copy control information is set, is input and recorded on an information recording medium as BDAV format data. As record data, (a) a stream file including a packet string in which the MMT format data is stored, and (b) copy control information corresponding to the stream file, in which the copy control information corresponding to the MMT format data is reflected, are generated and recorded as an additional header of a packet included in the stream file or as another file.

摘要： In a data processing apparatus and data processing method, each output system is controlled according to the contents of copy restriction based on control data so as to output digital data via one output system which is specified out of plural output systems. Therefore, when the control data show the copy restriction, digital data is previously prevented from being output via the plural output systems. As a result, a data processing apparatus and data processing method capable of conducting data control without fail are realized.

摘要翻译： 在数据处理装置和数据处理方法中，根据控制数据根据复制限制的内容来控制各输出系统，以便通过多个输出系统中指定的一个输出系统输出数字数据。 因此，当控制数据显示复制限制时，先前防止数字数据通过多个输出系统被输出。 结果，实现了能够无故障进行数据控制的数据处理装置和数据处理方法。
