摘要:
The present invention is directed to a data recording method of performing data recording while properly using at least two respective divided recording areas on an optical recording medium (5) in accordance with kind of data to be recorded, wherein in the case where inputted data is still picture, remaining capacity of the still picture recording area ARS is confirmed to judge whether or not remaining capacity of the video recording area ARV is larger than extension size when there is no remaining capacity of the still picture recording area ARS, whereby in the case where remaining capacity of the video recording area ARV is larger than extension size, boundary pointer is modified, and recording data management information and file system information are modified to thereby extend the still picture recording area ARS to record still picture data into the still picture recording area ARS to update recording data management information and/or file system information of management are ARM as occasion demands after recording is completed.

An information recording apparatus includes: a moving image input unit configured to input a moving image; a position information obtaining unit configured to obtain position information at the time of the moving image being input; a position information converting unit configured to convert the obtained position information into at least either bitmap data or text data, relating to a place determined with the position information thereof; a data stream generating unit configured to generate a data stream including at least either the converted bitmap data or text data, and video data corresponding to the input moving image; and a recording control unit configured to record the generated data stream as a moving image file.

To allow AV data created after the start of recording until the end of recoding to be easily continuously recorded and reproduced for a long time as a file. A stream of which AV data have been multiplexed is recorded to a file in the unit of a packet. When the file size exceeds 2 GB with the next packet that is recorded, record control is performed such that the time of the last end of audio data of the current file matches the time of the beginning of audio data of the next file to which the stream is recorded, the current file is closed, and seamless connection that denotes that the closed file and the next file to which the stream is recorded are connected such that audio data do not overlap is set. A file is newly created and the stream is continuously recorded thereto. The recording of the file is stopped according to a stop operation. When the recording is performed for a long time, a file is automatically divided. Upon reproducing, files in which the stream has been recorded for a long time can be continuously reproduced without causing the user to recognize the division of the file.

Management information for video data and audio data that are created after their recording is started until it is stopped and that are recorded as a stream file on a record medium is more securely stored. When their recording is started, EP entry information contained in management information of the stream file is created. Whenever EP entry information is created, it is written to a nonvolatile memory. After their recording is stopped, fixed value information and so forth that are contained in the management information are created and written to the nonvolatile memory. According to a disc eject operation, the management information written to the nonvolatile memory is written to the disc and the contents stored in the nonvolatile memory are cleared. Likewise, when power is turned off without the eject operation, information stored in the nonvolatile memory is written to the disc. Since the management information is stored in the nonvolatile memory, even if power is unexpectedly turned off, the management information will not be lost.

Recording of video data is enabled by a management structure of a clip which is compatible with a BD-ROM standard. In accordance with the recording starting operation, the recording of a stream in which the video data and audio data have time-divisionally been multiplexed on a packet unit basis onto a recording medium is started. In accordance with the recording stopping operation, the stream stored in a buffer is written as a stream file onto the recording medium and a clip information file corresponding to the stream file is formed. A play item showing the whole clip information file is formed and added to the existing play list on the recording medium. A mark is stamped to the play list at time corresponding to an IN point of the play item. Subsequently, the play item which is formed in association with the recording start and stop is similarly further added to the existing play list and the mark is further stamped at the time corresponding to the IN point.

摘要:
A method for initializing a recording medium on which data is recorded in compliance with the AVCHD standard is proposed.Under a root directory of partitions, an ICB and FIDs for each directory contained in a directory structure defined by the AVCHD standard are recorded with consideration of information on child directories. Thereafter, an SBD and a metadata bitmap file are recorded in a partition and also, an LVIS is recorded on the basis of information, such as the number of sectors used as a result of recording the ICBs and the FIDs of all the directories and the total number of directories.
