[Problems to be solved by the device]

  By the way, when recording digital data on a recording medium such as an optical disc, audio is used. In addition, it is recorded by digital compression by MP3 / Dolby-AC3 etc. Then, it is recorded by digital compression such as MPEG / Quick-Time. It is common. However, because it is compressed recording, information on the recording medium can be recorded from any point. When playing back, there is a certain amount of time It is necessary, and even if the user presses the play key, there is a time lag before the video / audio is output. The current situation is that it occurs. In addition, playback starts from the point where the user paused (interrupted). If you do, the video and audio at the point where decoding is completed will be a little behind the point where it was interrupted. It becomes a point, and a part that is not reproduced occurs. Therefore, watch the part that is not played To do this, the user must manually return the recording medium to the playback position at the point of interruption. It was

[0005]   Therefore, an optical disc or magnetic tape on which compressed video / audio data is recorded In the information reproducing apparatus which reproduces information of which recording medium, the reproducing operation for the recording medium is Video signal supplied to the display device after starting and supplied to the audio device It takes a required processing time until the audio signal is output. It read from the recording medium It expands (decodes) the compressed data that is output and converts it to an analog signal. Processing time, and this processing time is determined when recording information on the recording medium. It also depends on the bit rate being used.

[0006]   In this type of information reproducing apparatus, when reproduction on a recording medium is interrupted, The so-called resume playback in which the playback interruption point at that time is stored and the subsequent playback is performed If the playback is performed from the stored playback interruption point, Due to the delay due to processing time, the reproduction start point of information is It shifts to the slower side, so that between the playback interruption point and the playback start point Information is not output as video and audio signals, so video and audio Although the voice is cut, the user can play some resumes even though the resume playback is performed. There is a problem that you are not satisfied with the video and audio that is viewed. It was.

[0007]   For example, in the control method of the playback device described in Patent Document 1, the data is recorded on the optical disc. Compressed data is read by the optical head and temporarily stored in the memory. The address information of the read data from the memory is recorded in the backup storage means. Recall that when the playback operation is restarted, it is based on the backed up address information. Then, access the optical disc, and from the disc position corresponding to the address information. Read the recorded data and re-write it while controlling the writing / reading to / from the memory. By performing live, so-called resume playback that continues playback from the interrupted content It is possible.

[0008]   However, with this control method, the backup The optical disk is registered based on the address information backed up by the storage means. The compressed data from the point at which playback was interrupted can be obtained with the optical head, The obtained compressed data is expanded (decoded) and converted into an analog signal. It takes a certain amount of processing time to process and the information for that time is cut. I can't solve the problem.

[0009]   Further, in the resume reproducing method in the information reproducing apparatus described in Patent Document 2, the If you want to stop the live, from the storage device that temporarily stores the decoded data Search the playback position search information, obtain the relative addresses before and after the stop position, and play the next time. After the absolute start address is calculated, stop processing is performed. If the playback of is stopped midway, the next time it is played (resume playback), the Play from the set position (absolute address), for example, one minute before the previous stop position be able to.

[0010]   However, with this resume playback method, the resume is resumed from the position at which playback was interrupted. It is not possible to play the program correctly. Therefore, the user sees the same content for one minute, and users who do not want to see the same content. There will be discomfort for The.

[0011]   The present invention has been made to solve the above problems, and can be used for recording information on a recording medium.
