Abstract: To enable copy control according to original copy control information at a data output destination by converting copy control information defined in MMT format data into copy control information defined by DTCP and transmitting the converted copy control information to a network-connected device. The copy control information defined in the MMT format data is converted into the copy control information defined by DTCP and transmitted to the network-connected device. In the case where the transmission data is any of a 4K image, an 8K image, or an HDR image, and in a case where the copy control information defined by DTCP2 and the transmission data are images are 2K images or SDR images, the copy control information defined by DTCP1 is generated and recorded in a control information storage packet or a program map table (PMT) to be transmitted to a network-connected device, and transmitted.

Abstract: A virtual file system (VFS) is constructed by reliably acquiring subsequent data corresponding to an information recording medium from a local storage unit, and thus, data reproduction is executed. A data processing unit configured to read out and reproduce data recorded in the information recording medium, and data stored in the local storage unit which is different from the information recording medium, is provided. The data processing unit executes processing of selecting data associated with the information recording medium from the local storage unit, as reproduction target data, executes directory name calculation processing in which a conversion function corresponding to a version of the information recording medium is applied to configuration data of a root certificate recorded in the information recording medium, at the time of performing the processing of selecting the reproduction target data, and selects data which is recorded in a directory having a calculated directory name from the local storage unit, as the reproduction target data.

Abstract: 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.
