摘要： An information processing apparatus, an information processing method, a program storage medium, and a program for permitting the selection of a recording method maximizes the number of consecutive angle change units with priority given to an AV stream rate. A target AV stream rate is acquired, a jump distance is selected, and a jump time corresponding to the selected distance is acquired. A minimum angle change time is calculated from the jump time and a data read rate. The size of a minimum angle change unit is determined from the minimum angle change time and the AV stream rate. The number of minimum angle change units within the jump distance is calculated. The number of recordable angles is checked. The method is selected whereby the largest number of data items can be recorded consecutively on condition that the necessary number of angles is provided. This invention can be applied to recording/reproducing apparatuses.

摘要： This invention relates to an information processing apparatus, an information processing method, a program storage medium, and a program for permitting the selection of a recording method whereby the number of consecutive angle change units is maximized with priority given to an AV stream rate. In steps S91 through S93, a target AV stream rate is acquired, a jump distance is selected, and a jump time corresponding to the selected distance is acquired. In step S94, a minimum angle change time is calculated from the jump time and a data read rate. In step S95, the size of a minimum angle change unit is determined from the minimum angle change time and the AV stream rate. In step S96, the number of minimum angle change units within the jump distance is calculated. In step S97, the number of recordable angles is checked. In step S99, the method is selected whereby the largest number of data items can be recorded consecutively on condition that the necessary number of angles is provided. This invention can be applied to recording/reproducing apparatuses.

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： 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： There are provided an information providing system, a reproduction device and method, an information providing device and method, a recording medium, and a program capable of comparatively freely utilizing the content recorded on a disc according to the user preference. When download of an audio file of Japanese language is instructed, the update file of the content recorded on the optical disc (11) is downloaded. The Audio stream file as an audio file of Japanese language, the Clip Information file accompanying it, the Play List file controlling the reproduction of the Audio stream file, and the navigation program file which has been updated are recorded as the update file in a local storage (12). By the navigation program which has been updated, for example, the Audio stream file of Clip 3 as the Japanese language audio is reproduced. The present invention can be applied to a player to which a recording medium where the content has been recorded is detachably attached.

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.
