Abstract: Executes a re-encoding after decoding data of a connection section A of a first MPEG picture data. This re-encoding is executed based on a control such that a transition of a VBV buffer occupation value starts from a VBV buffer occupation value at a position a and ends with a VBV buffer occupation value at a position d. Up to the position a of the first MPEG picture data, the first MPEG picture data is reproduced. Next, re-encoded MPEG picture data of the connection section A is reproduced. Thereafter, the data is connected to the position d of a second MPEG picture data, and the second MPEG picture data of the position d and after is reproduced.

Abstract: An audio signal is compressively encoded into encoding-resultant audio data. A video signal is compressively encoded into encoding-resultant video data. An audio time stamp for audio-vide synchronous reproduction is added to every unit of the encoding-resultant audio data. A video time stamp for audio-video synchronous reproduction is added to every unit of the encoding-resultant video data. The time-stamp-added audio data and the time-stamp-added video data are multiplexed into main data. To a plurality of first after-recording-purpose data for at least one of (1) the encoding-resultant audio data and (2) the encoding-resultant video data which form the main data, time stamps for reproduction synchronous with a portion of the main data and identification information for identifying the plurality of first after-recording-purpose data are added to convert the first after-recording-purpose data into second after-recording-purpose data.

The playlists and the playlist management tables are recorded on the recording medium.

Abstract: A once-recordable optical disk has a data recorded area in which application software for creating an information group and a first file system are prerecorded. The application software is readable with the first file system and is used to select desired ones from among information pieces stored in a personal computer and form the information group. According to instructions from the application software, a second file system and the information group readable with the second file system are written in a blank area of the optical disk. After the creation of the information group, the application software and first file system in the optical disk are disabled so that they are unreadable with the second file system.

Abstract: An input unit receives an information sequence. A first encoding unit performs at least a portion of a block encoding process on the information sequence to generate a first code sequence. A second encoding unit performs the block encoding process on a first check symbol sequence in the generated first code sequence to generate a second code sequence. A generating unit combines a second check symbol sequence in the generated second code sequence with the input information sequence to generate a third code sequence.

Abstract: An audio disk has a first audio zone and a second audio zone. In the first audio zone, both of a plurality of tracks each including a single piece of music and a first management information including first control information for allowing each track to be reproduced are recorded. The music is composed of audio data produced from either a linear PCM signal or a signal produced by applying lossless compression to the linear PCM signal. In the second audio zone, music composed of audio signal produced under lossy compression, a plurality of files each storing a signal of a single piece of music subjected to the lossy compression, and second management information including second control information for allowing each file to be reproduced are recorded. Each piece of music stored in each file corresponds to the music included in any one of the tracks in the first audio zone.

Abstract: Each record of a file recording management table has three fields: Type, Contents, and Next Record Number. The Type field indicates whether the record is a “file name record” that has file name information in the Contents field or a “consecutive recording area record” that has position information on a consecutive recording area (position information on a positionally consecutive recording area) of file data in the Contents field. The records are linked and are recorded in one physical recording area as one file recording management table.

Abstract: A writable storage medium has a first storage area divided into a plurality of sectors having the same data capacity and a second storage area. The first storage area stores at least encoded moving picture data and encoded audio data. The second storage area stores at least first information indicating whether the audio data is silence data, second information indicating an encoding method by which the audio data has been encoded at a constant bit rate and third information indicating the number of audio channels related to the audio data. The first and second storage areas may further store encoded bitmap video data and data identification information indicating whether the bitmap video data is invisible data, respectively. The first information is detected to determine whether the first audio data is silence data.

Abstract: An optical disc has a laminate of recording layers. The recording layers have tracks respectively. The tracks wobble in accordance with wobbling signals respectively, and thereby indicate the wobbling signals respectively. The wobbling signals result from modulation of bit streams formed by sequences of concatenated fixed-length words of a predetermined self-synchronizable code. Each of the words is composed of check point bits and information bits. The check point bits in each word represent a sync position and a layer identification information piece selected from different layer identification information pieces assigned to the recording layers respectively for indicating which of the recording layers the related word is assigned to. The information bits represent address information. A drive apparatus for a multi-layer optical disc, and a method of making a decision on a currently-accessed recording layer in a multi-layer optical disc are also disclosed.
