    摘要: A block key to encrypt block data is generated using an ATS (arrival time stamp) appended to each of TS (transport stream) packets included in a transport stream correspondingly to the arrival time of the TS packet. The ATS is a random data depending upon an arrival time, and so a block-unique key can be generated, which enhances the protection against data cryptanalysis. A block key is generated from a combination of an ATS with a key unique to a device, recording medium or the like such as a master key, disc-unique key, title-unique key or the like. Since an ATS is used to generate a block key, any area for storage of an encryption key for each block may not be provided in a recording medium.

    摘要: The present invention relates to an apparatus and a method for reproducing a recording medium that require input of a code number only once when the code number is required to be inputted to both a directory and a PlayList for reproduction. A plurality of directories such as DVR, DVR1, DVRn and the like are formed on a disk. One directory DVR has a flag DVR_protect_flag set therein for controlling reproduction of information belonging in the directory. Also, .rpls in PLAYLIST, which is one piece of information in the directory DVR, has a playback_control_flag set therein for controlling reproduction thereof. In a case where the DVR_protect_flag is 1, the reproduction is allowed only when a correct code number is inputted. In a case where the DVR_protect_flag and the playback_control_flag are both 1, input of the code number for the playback_control_flag is omitted when the correct code number has already been inputted for the DVR_protect_flag.

    摘要: Control data subsequent to an extension start code is stored in an encoding apparatus when transmitted after each header data of a video sequence layer, a GOP layer, a picture layer and a slice layer. And in transmission of the next header data, the content of the control data subsequent to the extension start code in the header data to be transmitted is compared with the content of the preceding header data of the same layer stored in the encoding apparatus. And if the result of such comparison signifies that the compared data are mutually the same, neither the extension start code nor the subsequent control data is transmitted. At the reception of each header data of the video sequence layer, the GOP layer, the picture layer and the slice layer, the control data decoded subsequently to the extension start code is stored in the decoding apparatus. And when the extension start code is not existent in the next header data to be decoded, the preceding header data of the same layer stored in the decoding apparatus is duplicated and used as the control data of the layer being currently encoded.

    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。
