The invention provides a recording/reproduction apparatus and method as well as a recording medium wherein, when nondestructive editing is executed for an AV signal, the AV signal can be reproduced seamlessly without suffering from any interruption. Information representative of states (an A type, a C type, a D type, or an E type) of an IN point and an OUT point on a Clip, designated by a Playitem, of a Playlist in which at least more than one Playitems are arranged in the order of reproduction is described in a block Playitem( ).

When recording data on a medium where a certain data rate is required, an allocation manager in the player must allocate sections of the logical space in such a way that the recording medium is efficiently filled and that an adequate data rate can be guaranteed even in the presence of defective ECC blocks. The allocation rules for the allocation manager are complex. The rules can be simplified by placing a lower limit on the size of an extent and by increasing the size of the extent depending on the number of defect ECC blocks in the extent.

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.

A multiplexed stream is inputted, and a video stream is separated therefrom. A predetermined conversion process is performed on the separated video stream. Whether multimedia coding data is contained in the multiplexed stream is determined. Coding control information for instructing the predetermined conversion process to not change a display format of the video stream is generated when the multimedia coding data is contained in the multiplexed stream. A multiplexed stream is generated which includes the converted video stream.

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.

A computer-readable medium has data stored thereon for processing by an image decoding apparatus so that multimedia content is presented in an intended manner by a display. A data recording area contains data representing a converted video stream, at least another stream, and multimedia coding data for controlling display of the video stream and the at least another stream on a common display device. The converted video stream is generated by performing a predetermined conversion process on an original video stream. The predetermined conversion process is controlled by additional information such that a display mismatch between the converted video stream and the at least another stream is avoided. The additional information is based on the multimedia coding data.

A configuration is provided which improves scrambling processing of content and eliminates unauthorized use of content. Scramble rules which differ for each content are used for content scrambling processing. For example, in the event of using shuffling processing, various shuffle states are specified as scramble rules. In the event of using Exclusive-OR processing, a value applicable to EXOR is specified as the scramble rule. Also, in the event of using rotation processing, a shift amount is specified as the scramble rule. In the event of using 32 shuffle elements in shuffling processing, 32! different shuffle states, that is to say, 32! different scramble rules can be specified. Also, the values for EXOR or the rotation shift amount can be set as various values, and many scramble rules can be set.

An image coding apparatus is provided. A selector receives a multiplexed transport stream that includes multimedia coding data. A demultiplexer separates a video stream from the multiplexed transport stream. A decoder reproduces the video stream as decoded video data. A coding generator receives multimedia information associated with the multimedia coding data and generates display control information. The display control information includes a mismatch flag which indicates whether a display mismatch condition exists between the video data and multimedia coding data. An output unit outputs the decoded video data, the multimedia coding data and the mismatch flag.

A transmit device and method, a record/play device and method, a record system as well as a media allowing selection of the ideal record media by the receiver. The EPG data generator of a transmit device generates an EPG (Electronic Program Guide) showing the scheduled transmission of the program to be broadcast. An editor generates supplemental information containing information indicating the program data quantity, adds the supplemental information to the EPG and a multiplexer transmits the EPG added with the supplemental information.

A transport stream recording device, method thereof, transport stream reproduction device, method thereof, and recording medium for efficiently recording and reproducing transport streams. A source packet having a four byte TP_extra_Header attached to a 188 byte transport packet is generated, 32 source packets of 192 bytes each are collected, and aligned units generated equivalent to a three sector portion of data (6144 bytes) are recorded or reproduced on the recording medium.
