Abstract
If, in encoding and recording an AV stream, time_controlled_flag as the attribute information is set to 1, the relation between the time lapse of an AV stream and the amount of data bytes of the AV stream is linear within a preset error range. If the time_controlled_flag of the AV stream file is set to 1, and a certain time portion of the stream is erased by way of partial stream erasure, an unoccupied area corresponding to the erased time portion and which can be recorded at a bitrate indicated by TS_average_rate may be created on the disc.
Claims12
An encoding apparatus for encoding picture data, comprising:
- an encoder for encoding said picture data at a variable rate;
- and
- a controller for managing control so that the amount of picture coding data will be substantially proportionate to the time lapse.
An encoding method for encoding picture data, comprising:
- an encoding step of encoding said picture data at a variable rate;
- and
- a controlling step of managing control so that the amount of picture coding data will be substantially proportionate to the time lapse.
A recording medium having recorded thereon a computer-readable program used for controlling an encoding apparatus encoding picture data;
- said program comprising:
- an encoding step of encoding said picture data at a variable rate;
- and
- a controlling step of managing control so that the amount of picture coding data will be substantially proportionate to the time lapse.
A program for causing a computer controlling an encoding apparatus encoding picture data to execute
- an encoding step of encoding said picture data at a variable rate;
- and
- a controlling step of managing control so that the amount of picture coding data will be substantially proportionate to the time elapsed.
A recording medium having picture data recorded thereon, said recording medium having recorded thereon an AV stream file including said picture data and audio data associated with said picture data;
- and
- a flag indicating the recording mode of said AV stream file.
