摘要:
A configuration of performing reliable source analysis of the illegally copied content by using content for which a playback path can be configured is realized. Content is used which has a segment region configured with a plurality of pieces of variation data which can be respectively decrypted by different keys, and for which a playback path can be configured according to selected variation data. In each piece of variation data, a variation data identifier can be analyzed from the decrypted data. The playback device selects variation data according to the playback path information received from the server, and plays content. The server generates management data in which the playback path information notified to the playback device and the playback device identification information are associated with each other, and performs the source tracing of illegal copy, based on the variation data included in the illegally copied content.

A camera event logger device coupled to a motion picture camera, including: a data port configured to receive control signals to manage the logger device including a particular receive frequency; a radio-frequency receiver configured to receive time signal of the particular receive frequency to enable fine adjustment of a timecode; a timecode manager including a plurality of timecode readers and at least one timecode generator, a first timecode reader of the plurality of timecode readers configured to receive the time signal from the radio-frequency receiver and make the time signal available to the at least one timecode generator, wherein the at least one timecode generator is configured to generate the timecode by conditioning the time signal, the timecode manager configured to receive camera timecode from the motion picture camera, and to send back adjusted camera timecode adjusted in accordance with the conditioned timecode; a processor configured to receive camera status information from the motion picture camera and the conditioned timecode from the timecode manager, wherein the camera status information is tagged with the conditioned timecode and processed to generate metadata files; and a storage unit configured to store the metadata files. Keywords include logger, timecode, and slate.

According to the present invention, a data reproduction process and a disc manufacturing process are carried out on the basis of disc type information as disc-recorded data configuration information. A reproduction apparatus executing data reproduction from a disc reads disc type information recorded on the disc, grasps the disc-recorded data configuration on the basis of the disc type information, and executes the data readout and reproduction processes at a transfer rate according to the grasped recorded data configuration. The disc type information includes zone setting information indicating whether the disc is a single-zone disc composed of a single transfer rate zone or a plural-zone disc composed of a plurality of different transfer rate zones. The reproduction apparatus performs data readout and reproduction by the use of algorithms corresponding to the zones.

To enable conversion of the MPEG-2 TS format data including the variation data into the MP4 format data and, the setting of the reproduction path or the source tracking even in the converted MP4 data. A data processing unit is included which converts MPEG-2 TS format data, which includes segment regions including a plurality of pieces of variation data decryptable with different keys and in which a reproduction path can be set according to the selected variation data, into the MP4 format data. The data processing unit selects the encrypted MP4 variation data from the segment regions of the MPEG-2 TS format and stores the MP4 variation data in an MP4 file while the selected MP4 variation data remains as encrypted data.
