Description

  The present invention relates to a multi-functional apparatus having a VCR function for reproducing a plurality of program data recorded in advance on a magnetic recording medium and a function for compressing and encoding the program data and digitally recording the data on a disk medium such as a DVD. More specifically, the video tape recorder-integrated composite apparatus is more suitable for extracting user-desired program data from a plurality of program data reproduced by a VCR and dubbing it onto a disk medium such as a DVD. It can be used.

  The conventional video tape recorder-integrated composite device always detects the index signal while reproducing the program data recorded in advance on the magnetic tape in the VCR unit when dubbing the program data on the magnetic tape to the DVD. Yes. When the index data is detected, the index detection notification is transmitted to the digital recording unit each time, whereby the digital recording unit is configured to compress and encode the program data from the VCR and divide and record it on the DVD.

That is, the index data from the magnetic tape is detected as needed while performing the dubbing operation, and the program data on the DVD is divided and recorded in synchronization with the detected data.

In other words, the function of automatically performing the dubbing process with a simple operation by the user could not be realized.

  For example, regarding the selection of a dubbing program, with respect to a rewritable / erasable DVD medium such as a DVD-RAM, it is not possible to selectively erase unnecessary programs after all the program data reproduced by the VCR unit is written to the DVD medium. For DVD-R, which is possible, but can be written only once at a low price, the program data that needs to be dubbed on the magnetic tape is selected and played each time, and the DVD section recording start / end operations are also performed. In addition, there was a problem that it was necessary.

    As for the selection of the dubbing order, the operation of the DVD recording unit is stopped every time the order is changed, and the program data to be recorded is determined again by cueing reproduction or fast-forwarding operation using the index detection of the VCR unit. There has been a problem that a complicated operation of starting VCR reproduction and DVD recording operation is necessary.

  In addition, regarding the dubbing image quality level selection, it is not possible to select the image quality level according to the remaining amount of DVD media or to select recorded program data. There has been a problem that it cannot be confirmed before dubbing operation whether the image can be recorded at the image quality level.

  The present invention solves the above-mentioned conventional problems. A user arbitrarily selects a recorded program from a plurality of program data recorded on a magnetic tape by a simple operation before dubbing, determines a recording order, and dubbing image quality. It is an object of the present invention to provide an apparatus that enables dubbing recording from a magnetic tape to a DVD medium as desired by a user by determining the level.

  In order to solve the above-mentioned conventional problems, the video tape recorder-integrated composite apparatus of the present invention is capable of digitally dubbing a video cassette recorder capable of recording and reproducing a program on a magnetic recording tape and a program reproduced by the video cassette recorder. A dubbing selection menu is displayed based on the index information detected at the time of fast-forwarding operation in the video cassette recorder before the dubbing operation. The dubbing operation is performed by the displayed dubbing selection menu.

  Further, the present invention is characterized in that the digital recording means is equipped with program data dividing means for dividing the program data to be recorded on the recording medium in accordance with the dubbing information from the dubbing selection menu.

  Furthermore, the video tape recorder-integrated composite apparatus is characterized in that it has recording order confirmation means, image quality level selection means, and free space confirmation means in the dubbing selection screen.

  According to the video tape recorder integrated composite apparatus of the present invention, it is possible to realize simple operations such as automatic dubbing recording from a magnetic tape on which a plurality of program data is recorded onto a DVD medium, setting of a recording image quality level, and the like.
