Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a reservation recording alarm device of a video cassette recorder according to an exemplary embodiment of the present invention. The key input unit 10, the microcomputer 20, the timer 30, the memory 40, and the tuner ( 50, a data separator 60, a decoder 70, a signal processor 80, an OSD (On Screen Display) driver 90, and a recording unit 100.

In FIG. 1, the key input unit 10 is for inputting a VPS or PDC code corresponding to a desired broadcast program by a viewer's operation, and the microcomputer 20 is input to a broadcast program reserved through the key input unit 10. When a control signal for storing a corresponding code is generated, and a code of a corresponding broadcast program from a broadcasting station provided from a decoder 70 to be described below is compared with a code of a reserved broadcast program stored in the memory 40, the codes are different from each other. The controller generates a control signal to alert the user, and generates a control signal for forcibly recording the broadcast program when a predetermined time elapses.

And, the memory 40 is a message for the code of the reserved broadcast program and the reservation error input through the key input unit 10 (for example, the code of the reserved broadcast program is different, please input again. The timer 30 stores the current time and provides it to the microcomputer 20.

Meanwhile, the tuner 50 tunes the broadcast program in the airwaves transmitted from the broadcasting station to provide it to the data separator 60, and the data separator 60 transmits a predetermined portion of the broadcast program tuned through the tuner 50 ( For example, the code of the corresponding broadcast program included in the vertical blanking section) is separated and provided to the decoder 70, while the remaining broadcast signals are provided to the signal processor 80, and the decoder 70 is a data separator. The code of the broadcast program separated at 60 is decoded and provided to the microcomputer 20.

In addition, the signal processor 80 processes the broadcast signal provided from the data separator 60 to provide the OSD driver 90 and the recording unit 100, and outputs a voice signal through a speaker (not shown). .

In addition, the OSD driver 90 displays an image signal provided from the signal processor 80 on a screen (not shown) while OSD processing an alarm message from the memory 40 provided through the microcomputer 20 to the screen. The display unit 100 records the broadcast signal provided from the signal processing unit 80 by the recording control signal from the microcomputer 20.

FIG. 2 is a flowchart for performing a reservation recording alarm method of a video cassette recorder according to the present invention, which will be described in detail with reference to the block diagram shown in FIG.

First, when a viewer inputs a VPS or PDC code corresponding to a desired broadcast program through the key input unit 10 (step 210), a corresponding key signal is provided to the microcomputer 20, and from the microcomputer 20 The VPS or PDC code input through the key input unit 10 is stored in the memory 40 by the control signal for storing (step 212).

The microcomputer 20 then switches to the reserved recording standby state by comparing the current time counted by the timer 30 with the start time of the reserved broadcast program stored in the memory 40 (step 214).

Meanwhile, the broadcast signal transmitted from the broadcast station is tuned through the tuner 50 (step 216), and the tuned broadcast signal is separated through the data separation unit 60. Specifically, a predetermined portion of the broadcast signal (for example, The code of the broadcast program included in the vertical blanking section) is separated and provided to the decoder 70, and the remaining broadcast signal is provided to the signal processing unit 80 (step 218).

Then, the code for the broadcast program from the broadcasting station separated through the data separator 60 is decoded through the decoder 70 and then provided to the microcomputer 20, and the remaining broadcast separated through the data separator 60 is provided. After the signal is processed through the signal processing unit 80, the video signal is displayed on the screen through the OSD driver 90, while the audio signal is output through the speaker.

On the other hand, the microcomputer 20 compares the code for the broadcast program from the broadcasting station provided from the decoder 70 with the code of the reserved broadcast program stored in the memory 40 (step 220). Checks whether the broadcast start time has been reached (step 222), and if the broadcast start time has not reached, the reserved recording wait (step 224).

As a result of the check in step 222, when the broadcast start time comes, the microcomputer 20 generates a control signal for recording the broadcast program to the recording unit 100, and the recording control signal from the microcomputer 20 to the recording control signal. The broadcast program signal-processed by the signal processing unit 80 is recorded through the recording unit 100 (steps 222 and 226).

On the other hand, if the code for the broadcast program from the broadcast station provided from the decoder 70 and the code for the reserved broadcast program stored in the memory 40 are different from each other, the microcomputer 20 generates a control signal for alarming this. In response to the alarm control signal from the microcomputer 20, the alarm message stored in the memory 40 (for example, the code of the reserved broadcast program is different, please input again.). OSD is processed and displayed on the screen (step 228).

On the other hand, the microcomputer 20 checks whether the time counted by the timer 30 has passed a predetermined time (for example, 1 minute) (step 230). The predetermined time (1 minute) is displayed by the viewer. This is a time for modifying the code for the reserved broadcast program, which may be set differently depending on the situation.

At this time, when the time counted by the timer 30 passes the predetermined time, the microcomputer 20 generates a control signal for forcibly recording the broadcast program, and the microcomputer 20 generates a control signal. The broadcast program is forcibly recorded through the recording unit 100 by the recording control signal (steps 230 and 226).

As described above, when the code of the reserved broadcast program input through the key input unit 10 and the code of the broadcast program transmitted from the broadcasting station are different from each other by the viewer's operation, the memory is controlled by the alarm control signal of the microcomputer 20. The alarm message stored in the 40 is OSD processed through the OSD driver 90, and then displayed on the screen. When a predetermined time elapses, the broadcast program reserved by the viewer is forcibly recorded through the recording unit 100.

Therefore, according to the present invention, the code error of the reserved broadcast program is displayed on the screen and forced recording is performed even if the code is not corrected after a predetermined time elapses, so that the desired broadcast program is not recorded due to the wrong operation of the viewer. There is an effect that can be prevented in advance.
