Transport stream generating apparatus, recording apparatus having the same, and transport stream generating method

A transport stream generating method for generating a transport stream from video data to be recorded on a data recording medium on which recording is carried out in a predetermined unit, the transport stream generating method comprising:

• a video data encoding step for encoding video data so as to generate a video packet;
• and
• a multiplexing step for time-division multiplexing a plurality of fixed-length transport packets including at least a video packet so as to generate a transport stream,
• wherein, in the multiplexing step, n or more transport packets other than a video packet are inserted between a video packet group generated from a single encoding unit in the video data encoding step and a video packet group subsequent to the video packet group, and
• when d indicates a data length of the transport packet, h indicates a data length of a fixed-length header added to each of the transport packets before being recorded on the data recording medium, and L indicates a recording unit length to the data recording medium,
• L≦(n+1)×(d+h)
• is satisfied.

A transport stream generating LSI for generating a transport stream from video data to be recorded on a data recording medium on which recording is carried out in a predetermined unit, the transport stream generating LSI comprising:

• a video data encoding portion for encoding video data so as to generate a video packet;
• and
• a multiplexing portion for time-division multiplexing a plurality of fixed-length transport packets including at least a video packet so as to generate a transport stream,
• wherein, the multiplexing portion inserts n or more transport packets other than a video packet between a video packet group generated from a single encoding unit by the video data encoding portion and a video packet group subsequent to the video packet group, and
• when d indicates a data length of the transport packet, h indicates a data length of a fixed-length header added to each of the transport packets before being recorded on the data recording medium, and L indicates a recording unit length with respect to the data recording medium,
• L≦(n+1)×(d+h)
• is satisfied.
