摘要： An audio stream is divided into a plurality of audio object (AOB) files that are recorded having each been encrypted using a different encryption key. At least one piece of track management information (TKI) is provided corresponding to each track. Playlist information (PLI) assigns a playback position in a playback order to each track when a plurality of tracks are to be played back one after the other.
摘要翻译：音频流被分成多个被记录的音频对象（AOB）文件，每一个都使用不同的加密密钥进行加密。对应于每个轨道提供至少一条轨道管理信息（TKI）。播放列表信息（PLI）在多个曲目要一个接一个地播放时，以播放顺序将播放位置分配给每个轨道。

摘要： A recording medium capable of executing menu calls based on the particular characteristics of different versions of the same movie work when these different versions are recorded on a single recording medium. An AV clip and a dynamic scenario are recorded on a BD-ROM 100 (recording medium). The dynamic scenario is a command string showing a playback control procedure relating to video data, and has attribute information attached thereto. Attribute information is information showing a control procedure for when a user requests a menu call during AV clip playback, and includes a resume_intension_flag. The resume_intension_flag shows whether playback resumption of video data after the menu call ends is intended.

摘要： To provide a content playback device capable of protecting content according to DRM, when decrypting encrypted content recorded on a recording medium and playing the decrypted content. If key generation information is “00”, a key control unit 104 concatenates a decrypted media key and content information in this order, and applies a one-way function to the concatenation result to generate a content key. If the key generation information is “10”, the key control unit 104 sets a rights key as the content key. If the key generation information is “01”, the key control unit 104 concatenates the decrypted media key and the rights key in this order, and applies a one-way function to the concatenation result to generate the content key.

摘要： A playback apparatus judges whether a region code assigned to a BD-ROM matches a region code assigned to the playback apparatus. When the judgment result is in the affirmative, the playback apparatus plays back the content recorded on the optical disc. When the judgment result is in the negative, the playback apparatus does not play back the content, except when an exceptional playback is authorized. The exceptional playback is authorized when a combination of the content identifier of the content to be played back and the apparatus region code satisfies a predetermined condition defined by an owner of the rights of the content.

摘要： A recording device performs recording on a recording medium such as a DVD, and playback compatibility of the recording medium is increased. In circumstances such as when a standard is established after the manufacture of a playback apparatus, there are playback devices that physically cannot read information for decrypting encrypted data from a predetermined area of the recording medium due to the specifications of the playback apparatus, and therefore the playback apparatus cannot use the recording medium. In order for the recording medium to be able to be used in such a playback apparatus, the recording device reads data recorded in the predetermined area of the recording medium, and records the read data in another area that is readable by the playback apparatus.
摘要翻译：记录装置在诸如DVD的记录介质上执行记录，并且记录介质的回放兼容性增加。在制作播放装置之后建立标准的情况下，由于播放装置的规格，存在物理上不能读取从记录介质的预定区域解密加密数据的信息的重放装置，因此，播放装置不能使用记录介质。为了能够在这种播放装置中使用记录介质，记录装置读取记录在记录介质的预定区域中的数据，并将读取的数据记录在再现装置可读的另一区域中。

摘要： An optical disk for recording stereoscopic videos and high-quality video signals and a system for reproducing the videos and signals from the optical disk are made compatible with the conventional video reproducing system. A reproducing device which is used for reproducing stereoscopic videos and high-quality videos obtains stereoscopic video or high-quality videos by reproducing both first and second interleaved blocks on the optical disk in which first and second video signals are alternately recorded on the left and right sides by dividing the first and second video signals into frame groups of one GOP or more and a reproducing device which is not used for reproducing the stereoscopic videos and high-quality videos obtains ordinary videos by only reproducing either the first or second interleaved block by jumping tracks.
