Abstract
The navigation generator 12 sets the time length of a VOB to a time length that is determined in advance depending on a scheduled recording time H. Even if a user makes an operation to stop the recording before the time length of a recorded part of the VOB equals the predetermined time length, the VOB of the predetermined time length is recorded onto a DVD±R. Cell information specifying the part of the VOB preceding the point corresponding to the recording stop is generated. Then, PGC information containing the Cell information is recorded onto the DVD±R.
Claims9
A recording device for recording a digital stream onto a recording medium after determining a time length of the digital stream to be recorded, comprising:
- a first control unit operable to record the digital stream onto the recording medium for the determined time length, even if a user makes a stop operation before the determined time length is reached;
- a generating unit operable to generate playback section information specifying, as a playback section, a part of the digital stream recorded up to a point at which the stop operation is made;
- and
- a second control unit operable to record playback path information containing the playback section information onto the recording medium.
A recording device for recording a video object on to a recording medium after determining a time length of the video object to be recorded, comprising:
- a first control unit operable to record the video object onto the recording medium for the determined time length, even if a user makes a stop operation before the determined time length is reached;
- a generating unit operable to generate cell information specifying, as a playback section, a part of the video object recorded up to a point at which the stop operation is made;
- and
- a second control unit operable to record program chain information containing the cell information onto the recording medium.
A recording method for recording a digital stream onto a recording medium after determining a time length of the digital stream, comprising the steps of:
- recording the digital stream onto the recording medium for the determined time length, even if a user makes a stop operation before the determined time length is reached;
- generating playback section information specifying, as a playback section, a part of the digital stream recorded up to a point at which the stop operation is made;
- and
- recording playback path information containing the playback section information onto the recording medium.
