摘要： Contents data that have been enciphered and transmitted are recorded as they are on a recording medium, and the contents key used to encipher these data is enciphered in a way used in this recording system and is recorded on the medium. Moreover, a step is taken to ensure that fine trick plays can be performed. In recording contents data that have been enciphered and transmitted, the contents data themselves are recorded in the enciphered state on the recording medium. However, the contents data are decoded by a contents data decoding circuit 46, and a map file containing necessary management information for reproduction is created by a map file creating circuit 47 and this file is recorded together with the contents data.

摘要： A configuration is provided wherein usage restrictions of an application are determined in accordance with timestamps. A certificate revocation list (CRL) in which the revocation information of a content owner who is a providing entity of an application program recorded in a disc is recorded is referred to verify whether or not a content owner identifier recorded in an application certificate is included in the CRL, and in the case that the content owner identifier is included in the CRL, comparison between a timestamp stored in a content certificate and a CRL timestamp is executed, and in the case that the content certificate timestamp has date data equal to or later than the CRL timestamp, utilization processing of the application program is prohibited or restricted. According to the present configuration, a configuration is realized wherein an unrevoked application is not subjected to utilization restriction, and only a revoked application is subjected to utilization restriction.

摘要： To realize a configuration to output content to a medium and to use the content stored in the medium under control of the use of content.A content-output-device outputs an encrypted content and an encryption key to be applied to the using process to the medium, and a management server generates a media ID verification value based on a media ID that is an identifier of the medium and transmits the value to the medium. The medium stores the encrypted content, the encryption key, and the media ID verification value in a storage unit. A reproduction device loads the medium and calculates a verification value based on the media ID acquired from the medium, and executes a reproducing process of the encrypted content stored in the medium by data processing to which the encryption key is applied on condition that a matching process performed between the verification value and the media ID verification value stored in the medium is established.

摘要： For a large capacity recording medium, a user interface having high flexibility and enriched representation is accomplished. A flag that represents whether a play item has a multiple angle structure of which the play item is reproduced with a plurality of angles is described. In addition, a flag that represents whether the beginning of each decode unit is an angle switchable point is described. In a seamless multiple angle structure, the current angle can be switched without need to increase the number of interleave units. In a nonseamless multiple angle structure, with the flag, in a predetermined region on the rear end side of each angle, the current angle is prohibited from being switched. Thus, when a play item exits from the multiple angle, discontinuity in the reproduction can be prevented. In addition, with a flag that represents whether a sub play item should be reproduced not in synchronization with a main path, the sub play item of only audio data can be used as a BGM.
摘要翻译：对于大容量记录介质，实现了具有高灵活性和富集表示的用户界面。描述表示播放项目是否具有以多个角度再现播放项目的多角度结构的标志。此外，描述表示每个解码单元的开始是否是角度切换点的标志。在无缝多角度结构中，可以切换当前角度，而不需要增加交织单元的数量。在非缝合多角度结构中，通过标志，在每个角度的后端侧的预定区域中，禁止当前角度切换。因此，当播放项目从多个角度退出时，可以防止再现中的不连续性。此外，通过表示子播放项目是否应与主路径不同步再现的标志，只有音频数据的子播放项目可以用作BGM。
