Abstract: In case continuous reproduction is commanded from a first AV stream to a second AV stream, a third AV stream, made up of a preset portion of the first AV stream and a preset portion of the second AV stream, is generated. The third AV stream is reproduced when reproduction is switched from the first AV stream to the second AV stream. As information pertinent to the third AV stream, the address information of a source packet of the first AV stream at a time of switching from the first AV stream to the third AV stream and the address information of a source packet of the second AV stream at a time of switching from the third AV stream to the second AV stream, are generated. This enables reproduction such as to maintain continuity between separately recorded AV streams.

Abstract: 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.

Abstract: There is provided an apparatus and a method determining a data arrangement that guarantees seamless reproduction even in a case of occurrence of a jump in a browsable slide show. An allowable jump range between an image data clip and an audio data clip required for data reading in the browsable slide show in which a consecutive reproduction processing of a still image and an audio reproduction processing are performed in parallel is determined so as to determine arrangement conditions of data to be stored in an information recording medium on the basis of the determined allowable jump range. This configuration enables the browsable slide show to be carried out as a seamless reproduction processing without any data discontinuity. Furthermore, it becomes possible to provide a plurality of combinations of readout rates of the audio data and image data.

Abstract: The present invention displays subtitles in a language desired by a user in a desired format. A text data decoder 121 decodes text subtitle data, supplies a character object to a character object buffer 122, and supplies attribute data to an attribute data buffer 123. The attribute data stored in the attribute data buffer 123 is changed on the basis of an operation input from the user. A font rasterizer 124 converts the character object into raster data on the basis of attribute specification read from the attribute data buffer 123 and acquired font data, and outputs the raster data. By detecting each character object bearing a bookmark on the basis of the attribute and using a bookmark buffer 125, character objects bearing the same bookmark ID are prevented from being repeatedly rasterized. The present invention is applicable to a playback apparatus.

Abstract: An information recording and/or reproducing method for supervising the information, such as an input source, in a stream recorded on a recording medium. If, in a reproduction processing of reproducing an AV stream from the recording medium, the source_security_info, which is the copy control information recorded on the recording medium, is read out, the AV stream is read out, and analog video, for example, is output (step 203), it is verified, from the information contained in the source_security_info, whether or not the input source is DTCP-concordant. If the input source is DTCP-concordant, reproduction restricting processing for a video output, conforming to the DTCP rule, is executed to issue the video output.

Abstract: A playback apparatus includes an obtaining unit obtaining playback management information including a main playback path of a main stream set, a first sub playback path of a first sub-stream set, and a second sub playback path of a second sub-stream set. The first and second sub playback paths are allowed for a predetermined category. A selection-receiver receives a selection of streams as a first combination or a second combination. A reading unit reads the corresponding stream sets according to whether the first or second combination is selected. A playback unit plays back the main stream set and the first or second sub-stream set. The number of files that are readable at one time is predetermined. The sub playback paths are determined so that the number of the files that are readable at one time does not exceed the predetermined number.

Abstract: With a reproduction-only disc having a large recording capacity, an interactive function having a higher degree of freedom than the related art can be easily accomplished. A virtual player model corresponding to a function of a player is created and described in Java. BDBasicPlayer 210 detects a user input and the status change of the player and generates an event. An object 211 that implements a listener interface registers an event listener corresponding to an event that the object 211 is caused to receive to BDBasicPlayer 210 before the event takes place. When the event becomes unnecessary, it is unregistered. BDBasicPlayer 210 transmits the event to the object 211 in which the event listener has been registered. The object 211 executes a method corresponding to the received event. The relationships between events and methods can be flexibly set. Thus, a complicated interactive function can be easily accomplished.

Abstract: 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.

Abstract: An information recording apparatus and method and an information reproduction apparatus and method enable security information of AV data to be managed appropriately. A copy control information detection section acquires copy control information (CCI_i) of a video signal supplied from a terminal and outputs it to a controller. The controller determines the values of is_not_free and is_encrypted based on the copy control information supplied from the copy control information detection section and outputs the values to a source packetization section. Is_not_free and is_encrypted represent a limitation to copying and an encryption mode of data recorded on a recording medium, respectively, and are described in the header of a source packet produced by a source packetization section. The source packet produced by the source packetization section is encrypted in accordance with the value of is_encrypted, undergoes a predetermined process by an encryption section, and is then recorded onto the recording medium.
