For a content-prerecorded large capacity disc-shaped recording medium, a user interface having high flexibility is accomplished. Button image data, corresponding sound data as an effect sound, and control commands for the sound data and image data are multiplexed with a stream and recorded on the disc. A scenario reproduced from the disc is stored in a buffer 104. The image data and sound data are stored in a buffer 105. Image data is read from the buffer 105 in accordance with a scenario and expanded to a graphics plane 133. In addition, corresponding sound data is read from the buffer 105 and reproduced by a sound player 106D. When a button image is varied in accordance with a state change of the button, an effect sound is reproduced. As a result, a more effective user interface is accomplished.

A musical jukebox is disclosed which provides for: fast archiving of songs; a flexible user interface; easy and convenient entry of, access to and/or display of data relating to songs archived by the jukebox; easy and convenient search and locate capabilities for locating, reviewing, retrieving and/or playing songs stored in the jukebox; and low cost relative to the functionality, features, conveniences and user-friendliness provided by the jukebox. Fast of flush archiving of songs (as well as other data and signals) is accomplished by first saving sets of data without compression, which allows the data to be entered quickly, and then, compressing later at an appropriate time. A unique MP3 bit allocation encoding scheme is used to compress data. A unique memory allocation supports fast data archiving. The user interface employs two-way communication between a remote control and the jukebox. A searchable song database is structured to enable very fast searching by music category, and also by title and artist. The jukebox is provided with an on-board song track database to automatically identify new songs input to the jukebox.

An optical disc that is reproducible by a reproducing apparatus has a still picture data and an audio data which are reproduced simultaneously. The still picture data is stored in a video part stream (ST1) comprising a plurality of units, and the audio data is stored in a second system stream (ST2) comprising one or a plurality of units. The units store time stamp information so that the second system stream (ST2) follows immediately after the video part stream (ST1). By changing the data in the second system stream (ST2), the audio data presented with a still picture can be freely and easily changed even after recording the still picture data using an MPEG standard format.

A multimedia optical disk is provided. The multimedia optical disk includes a data area for storing objects which include moving picture data and at least one of audio data and sub-picture data. The multimedia optical disk also includes an index area for storing reproduction orders of the objects. Route information in the index area includes a sequence of addresses of objects whose alignment represents a reproduction order. Chain control information in the index area corresponds to the route information. The chain control information, being effective in reproducing objects specified by the alignment of the sequence of addresses (objects specified by the alignment of the sequence of addresses are called a chain), instructs the reproduction apparatus to have a navigation control of the chain. A piece of moving picture data having a certain time period is reproduced at the same timing as a piece of audio data and a piece of sub-picture data. A piece of sub-control information, being effective in reproducing moving picture data, sub-picture data, and audio data stored in a small unit instructs the reproduction apparatus to have a navigation control of the data stored in the same small unit.

An information editing apparatus for editing recording information already recorded on a write-once recording medium such as DVD-R is provided. In this apparatus, a remaining capacity in the DVD-R is detected. Then, it is determined whether the recording information can be edited or not on the basis of the detected remaining capacity and an amount of information to be recorded in the unrecorded area by editing the recording information. Further, a result of the determination is notified.

A digital television recording method comprising: broadcasting a television program associated with a broadcaster set of parameters enabling access to a first set of predetermined portions of the program; operating an agent for determining whether to record the program and for associating with the program, upon recording of the program, an agent set of parameters enabling access to a second set of predetermined portions of the program; storing the program together with the broadcaster set of parameters and the agent set of parameters to generate an addressable program; retrieving at least a portion of the addressable program; displaying the at least a portion of the addressable program to a user, receiving from the user a user set of parameters enabling access to a third set of predetermined portions of the addressable program; editing the addressable program to include the user set of parameters enabling access to the third set of predetermined portions of the addressable program thereby generating an edited addressable program; and storing the edited addressable program.

The erasion level appending range of a file is instructed. According to this instruction, the erasion level is set. When this setting range does not agree with the cell unit of the current cell, the current cell is divided to set a sequence of divided cells. Playback management information of each of the divided cells and current cell is re-created, and erasion level information is appended to playback management information of the divided cell that belongs to the appending range.

A controller makes a demultiplexer select a transport stream corresponding to user's operation, and supplies it to a VTR through an I/F circuit. The I/F circuit of the VTR gives the transport stream to a recording/reproducing unit for recording, and transmits EIT data to a TV to supply them to a program guide GUI generating part. The GUI generating part generates GUI data based on the inputted EIT data, and makes them stored in a cassette memory using a cassette memory unit of the VTR. At the time of reproduction, GUI data read by the cassette memory unit is supplied to the program guide GUI generating part, and a program guide display of programs recorded on a cassette tape is displayed. In this manner, guide information on programs recorded on a cassette tape is automatically displayed.

An information processing apparatus, as a recording apparatus, formulates a Clip Information file of a still picture file (TS file), made up by plural still pictures, and a PlayList, composed of plural PlayItems, indicating the replay path of a slide show, and records the information on a DVD along with the TS file. The Clip Information file has an EP_map, as a table indicating the relationship of correspondence between the value of the presentation time stamp PTS of the transport stream TS and the source packet number SPN in the TS the PTS value indicates. The information processing apparatus, as a reproducing apparatus, reads out and reproduces the data address of the TS, represented by the replay start time IN_time and the replay end time OUT_time of the PlayItem.

An adding unit 14 of a broadcasting apparatus 11 attaches entry information to a content to be broadcast. The entry information specifies a content that is identical to the content to be broadcast out of a plurality of contents available for distribution by a distributing apparatus 12. A sending unit 15 of the broadcasting apparatus 11 broadcasts the content with the entry information attached thereto. An entry information recording unit 106 of a recording apparatus 30 records the entry information that is attached to the received content to a hard disk 104, and a requesting unit 107 requests the distributing apparatus 12 to distribute the content specified by the recoded entry information. A content distributing unit 21 of the distributing apparatus 12 receives the distribution request, and distributes the requested content to the recording apparatus 30. The recording apparatus 30 plays back the distributed content.
