摘要： A data processing device for playing back a digital work reduces the processing load involved in verification by using only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on a DVD. In addition, the data processing device improves the accuracy of detecting unauthorized contents by randomly selecting a predetermined number of encrypted units every time the verification is performed.

摘要： A recording medium enables special playback processing although part of the AV stream recorded therein is transformed. An AV stream, a first EP map, and a second EP map are recorded on the recording medium. In the AV stream, a part of the multiplexed stream including a first video stream and a second video stream is transformed. The first EP map indicates one or more entry points of the first video stream and the second EP map indicates one or more entry points of the second video stream. TS packets constituting I-pictures of the first video stream are indicated by every 4N-th entry point in the first EP map, and TS packets constituting I-pictures of the second video stream are indicated by the entry points whose presentation time is closest to the presentation time of any one of the every 4N-th entry point in the first EP map.
摘要翻译：尽管其中记录的AV流的一部分被变换，但记录介质能够进行特殊的重放处理。 AV流，第一EP图和第二EP图记录在记录介质上。在AV流中，包括第一视频流和第二视频流的多路复用流的一部分被变换。第一EP映射表示第一视频流的一个或多个入口点，而第二EP映射表示第二视频流的一个或多个入口点。构成第一视频流的I图像的TS分组由第一EP图中的每第4N个入口点指示，构成第二视频流的I图像的TS分组由呈现时间最接近的入口点指示第一EP图中每4N入口点中的任何一个的呈现时间。

摘要： Provided is an information processing device including a data processing unit that executes reproduction processing of content recorded in an information recording medium. The content includes an individual segment region formed of a plurality of variation data in which identification information different from each other is embedded and each of which can be decrypted by a different key, and a common segment region formed of single data. The variation data is formed of a 6144 byte aligned unit. The data processing unit calculates a reproduction path by applying a device key held in a memory, and selects an aligned unit corresponding to one variation data that corresponds to the calculated reproduction path from a plurality of aligned units configuring the plurality of variation data in the individual segment region included in the data read from the information recording medium, and then, executes the decryption and reproduction processing.
