And an on-screen display unit (OSD) 60 for displaying caption information for deck selection at the time of reserved recording.

2 is a flowchart of a reservation recording method performed by the system controller shown in FIG.

According to FIG. 2, steps S1 through S3 are reserved input steps, steps S4 through S6 are reserved time comparison steps, step S7 is a recording mode initialization step, step S8 is a deck seating state checking step, and step S9 is a tape A state checking step, step S10 is a first recording step, steps S11 and S13 are a second recording step, and steps S13 to S15 are a third recording step.

Next, the operation of FIG. 1 will be described in conjunction with the flowchart of FIG.

When the user wants to make a reservation recording using the double deck VCR, the user turns on the power and inputs the reservation recording while watching the OSD (60) screen. That is, the reservation recording data such as the date to be reserved, the start time of the program, the channel, and the end time of the program, and the deck selection data for the selection of the first deck 30 or the second deck 40 are recorded. A key input unit 10 such as a function button or a remote control is inputted on the set of.

Deck selection data is to input data for the normal recording to select any one of the first and second deck continuous recording, the first and second deck simultaneous recording, the first or second deck. At this time, deck selection data is selected for each reserved recording program.

The first and second deck continuous recording may be continuously recorded to the second deck 40 when the recording of the first deck 30 is completed, or the first deck when the recording of the second deck 40 is completed. (30) and the first and the second deck simultaneous recording is the same reservation is performed on the first deck 30 and the second deck 40, it is possible to make two identical recording tape, The first or second deck recording allows only one deck to perform recording.

That is, the system 20 outputs clock, data, and strobe signals to the OSD 60 so that the following subtitle information is displayed on the OSD 60 screen.

When the table 1 is displayed on the screen of the OSD 60, the user can input data by pressing a key of the key input unit 10. Alternatively, the display can be displayed by lighting the corresponding deck selection mode number using a digitron instead of the OSD. When the reservation data input is completed in this way, the power is turned off (steps S1 to S3).

If the start time of the reservation program coincides with the reservation data input by completing the reservation data input, the system 20 turns on the power of the VCR (steps S4-S6), and the first and second decks 30 and 40 and the circuit unit. Initialize so that recording operation can be performed by operating (S7).

At this time, any one recording operation is performed according to the recording deck type set by the user. If 2 is set, the first and second decks 30 and 40 record the desired program by simultaneous recording.

However, when the tape of the first second decks 30 and 40 is drawn out or replaced by a non-recordable tape (when there is no REC SAFETY TAB) in the absence of a user, it is difficult to perform the above recording function normally. Therefore, the sheath cone 20 first checks whether or not the tape is seated on the first and second decks 30 and 40 and whether there is a tap of the tape.

If it is determined that both the first and second decks 30 and 40 have tapes on them and there is a recording tab, there is no problem in performing the recording function. Therefore, recording is performed according to the deck selection set by the user.

1) The tape is seated on the 1st and 2nd deck but there is no tab on either side

2) Tape is seated on the first or second deck and there is no tab

3) If both tapes are not attached to the first or second deck

4) When both tapes are not attached to the first and second decks

In case of 4) above, reservation recording cannot be performed normally due to inconsistency with the deck selection method set by the user.

That is, when the user selects the first and second deck continuous recording, 1) the deck cannot be recorded on one deck, 2) the same way the deck is not recorded on the deck, and 3) and 4) the scheduled recording is performed. It becomes impossible.

Therefore, the sheath cone 20 has a first deck seating switch SW1, a first deck safety switch (or first recording tap switch) SW11, a second deck seating switch SW2, A recording mode is performed by checking the input of the second deck recording tap switch (or second recording tap switch) SW12.

Here, H when deck is seated, L when deck is not seated, L when there is a tab, and H when there is no tab.

Table 2 below is an operation table summarizing the recording operation according to the present invention.

In the steps S8 to S10, both the tape is seated on the first deck 30 and the second deck 40, and both have a safety piece, so continuous recording, simultaneous recording, and first or second deck recording are possible.

In steps S11 through S12, both tapes are seated on the first deck 30 and the second deck 40. However, since there is no tab on either deck, recording is possible only on the deck having the recording tab.

In steps S13 to S15, the tape is seated on the first or second decks 30 and 40, and the tape is taped on the deck on which the tape is seated.

On the other hand, the program in which the deck is selected and the reserved recording time has been reached is recorded by the signal processing unit 50, and the signal recorded on the magnetic tape is reproduced by the signal processing unit 50.

Here, referring to the recording system operation of the signal processor 50, the received video signal corresponding to the recording time is separated into luminance and color signals. In order to record these signals directly to the tape, the luminance signal is FM-modulated, and the color signal is low-converted to a frequency band below the luminance signal, and then these two signals are synthesized through the video heads of the decks 30 and 40. Record on tape.

In addition, referring to the reproduction system operation of the signal processing unit 60, FM modulation is performed after filtering the luminance signal band from the video signal reproduced through the video heads of the decks 30 and 40. After filtering the signal below the luminance band, high frequency conversion is performed to the original color signal frequency band. The two signals are then synthesized and output on the screen.

As described above, the reserved recording apparatus and method according to the present invention are tapes in which the tape is not seated or the recording tab is not determined by judging the tape state of the first and second decks when performing the reserved recording in the double-deck VCR. In this case, since it is not recorded, the user provides a convenient function.
