The present invention relates to a two-channel simultaneous reservation recording method in a recording and reproducing apparatus. In particular, two video cassettes having one deck and a tuner can be used to simultaneously record programs of two different channels in the same time zone or overlapping time zones. It is about how it can be.

In general, a double deck video cassette recorder (VCR) consisting of two recording and reproducing apparatuses (hereinafter referred to as decks) as one unit has a function of recording a program of two different channels at the same time. However, in the videotape recorder with one deck and one tuner except for the double deck, if you want to record a program of another channel in the overlapping time during the reservation recording, the reservation start time is not fast because simultaneous recording is not possible. The high priority was determined by selecting a program of a channel or a low number of reserved recording channel numbers, and only one program having a high priority was executed.

Accordingly, an object of the present invention is to connect two recording and reproducing apparatus with one deck and a tuner in series to simultaneously identify and operate the two different channel programs at the same time or overlapping time periods by identifying the operating state of each recording and reproducing apparatus. To provide a way to make a reservation.

In order to achieve the above object, there is provided a first and second recording and reproducing apparatus having one deck and one tuner, and a first recording and reproducing apparatus having a reservation recording function and at least a second recording function. In the method of connecting a recording and playback device in series and simultaneously recording a time-duplicate program,

A program reservation step of reserving the time- duplicated first and second programs in the first recording / playback apparatus; and if the reserved time of the first program among the reserved programs from the program reservation step has been reached, the first program in the first recording / playback apparatus. After the recording, the automatic recording step of automatically recording the second program on the recording medium of the second recording / reproducing apparatus by checking the operation state of the second recording / reproducing apparatus, if the recording mode is not in the recording mode, And (2) a reservation recording completion step of checking whether the reservation recording is completed in the recording / reproducing apparatus and turning off the power when recording of the first and second programs is completed in each recording / reproducing apparatus.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of a two-channel simultaneous reservation recording method according to the present invention.

1 is a flowchart illustrating a method of simultaneously recording two channels according to the present invention. According to FIG. 1, steps S1 to S3 are program reservation steps, steps S4 to S11 are auto recording steps, and steps S12 to S20 are reserved recording steps.

2 is a view for explaining the first and second program time zones that are reserved in the program reservation step according to FIG.

FIG. 3 is a circuit diagram for performing the method of FIG. 1, in which a control command input unit 101 for transmitting a user's control command and information and a reservation recording function connected to an output terminal of the control command input unit 101 are added. At least a recording function connected in series to the first microcomputer 110 of the first VCR 100, the data input / output terminal DATA, the strobe signal output terminal STROVE, and the clock terminal CLK of the first microcomputer 110 is provided. The second microcomputer 210 of the second VCR 200, the first power supply unit 130 connected to the power terminal of the first microcomputer 110, and the second microcomputer 210 connected to the power terminal of the second microcomputer 210. And a power supply unit 220, a first servo unit 130 connected to the control output terminal of the first microcomputer 110, and a second servo unit 230 connected to the output terminal of the first microcomputer. The control command input unit 101, the first microcomputer 9110, the first power supply unit 120, and the first servo unit 130 correspond to the first VCR 100, and the second microcomputer 210 and the second power supply unit 220. And the second servo unit 230 corresponds to the second VCR 200.

Next, the two-channel simultaneous reservation recording method of FIG. 1 will be described with reference to FIGS.

In FIG. 1, first, the main power of the first VCR 100 is turned on (step S1), and the user inputs the first and second program information and the recording time for the program to be reserved by the control command input unit 101. Upon application, information about it is stored in a memory circuit (not shown) in the microcomputer 110, and the power supplied to the peripheral circuits other than the first microcom 110 in the system is turned off under user control. Let's do it. Here, information input for the reserved recording program is as known.

Here, the program to be reserved is a case where the second program exists in the first program (FIG. 2A), as shown in FIGS. 1A to 2C, and the first program and the second program are started simultaneously. When the first end (Fig. 2b), the first program and the second program has a different starting point, and the completion point is different, but there is an overlap (Fig. 2C) (steps S2 and S3).

The timer counter (not illustrated in the drawing) in the first microcomputer 110 continuously checks whether the increased time coincides with the program reservation recording time while increasing by one (steps S4 and S5).

When the program (PRO) recording time is recorded, it is determined whether the first VCR is in the recording mode. If the first VCR 100 is not in the recording mode, power is supplied to the first servo unit 130 in the first VCR 100. Control to perform the recording mode for the first program (PRO1) and then feed back to step S4 (steps S6 to S8).

In operation S6, when the first VCR 100 is in the recording mode, the operation state of the second VCR 200 is checked. If the second VCR 200 is not in the recording mode, power is supplied to the second VCR 200 to supply the second VCR 200. After performing the recording mode by controlling the second servo unit 230 for the program PRO2, it feeds back to step S4, and feeds back to step S4 even when the second VCR 200 is performing the recording mode (S9 to S11). step).

After the PRO reservation is completed through the steps S4 to S11, it is checked whether the first VCR 100 is in the recording mode. If the first VCR 100 is in the recording mode, the scheduled recording of the first program PRO1 is completed. When the first VCR 100 reserves the recording of the first program PRO1, the first servo unit 130 is controlled to perform the stop mode (steps S12 to S14).

The second VCR 200 determines whether the recording mode is being performed, and feeds back to step S4 if the recording mode is being performed, and turns off the power (steps S15 and S20). In step S12, if the first VCR 100 is not in the recording mode, it is determined whether the second VCR 200 is in the recording mode, and if the second VCR 200 is in the recording mode, the scheduled recording of the second program PRO2 is completed. If the second VCR 200 reserves the recording of the second program PRO2, the second servo unit 230 is controlled to perform the stop mode STOP (steps S16 to S18).

Again, it is determined whether the first VCR 100 is in the recording mode and feeds back to step S4 if recording is in progress. Otherwise, the power is turned off to complete the two channel reservation recording (steps S19 to S20).

As described above, the two-channel simultaneous reservation recording method according to the present invention is a redundant time zone reserved for the second VCR connected in series with the first VCR when the two-channel program having a duplicated time is reserved for the first VCR capable of reservation recording. By recording a program in, it is effective to record a program of two different channels in the same time zone or overlapping time zones.
