Abstract

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.
