Hereinafter, a method for displaying reservation recording status of a composite television of the present invention will be described in detail with reference to the accompanying drawings.

First, a schematic operating state of the complex television in which the method of the present invention is performed will be described with reference to FIG. 1. As shown, the composite television includes a tuner 1 for receiving a broadcast signal and passing only a signal of a specific broadcast station. The signal output from the tuner section 1 is input to an IF amplifier section 2 for modulating it and amplifying it to a signal of a particular size. The signal modulated and amplified by the IF amplifier 2 is input to the main IC unit 3, which separates the R, G, and B signals from the audio signal. The main IC unit 3 includes various circuits therein, and is an IC in which various circuits that have been separated conventionally are integrated into one module. The R, G, and B signals output from the main IC section 3 are input to the CRT driving section 4 and finally output to the CRT 5.

On the other hand, the sound signal output from the main IC unit 3 is output through the speaker 7 after sufficient creeping and amplification in the amplifier 6.

In addition, the video processing unit 10 for processing the video signal output from the main IC unit 3 as a signal that can be recorded by the video deck unit 9, and the microcomputer 8 that controls the entire device includes It is.

The method of the present invention carried out in the composite television having the configuration as described above is the following steps: by detecting the on / off state of the power in the microcomputer (8) performs a normal output operation when the power is on, the power is off A first step of checking whether there is a reservation recording in the state; Setting the display flag to 0 if the reservation recording is not set and setting the time-record flag to 1 if the reservation recording is set; A third step of performing a reservation recording and setting the display flag to 1 when the time is identical by comparing the current time with the reservation recording time while the reservation recording is set; A fourth step of waiting for a power key input by the viewer when the reservation recording ends; When the power command is detected by the viewer, the power is turned on and the state of the display flag is read. If the display flag is 1, the recording is terminated. If the display flag is 0, the display device is configured to perform a normal output operation.

The method of the present invention as described above will be described with reference to the flowchart of FIG. 3.

The method of the present invention is applied to a reservation recording of a broadcast on a composite television. When a reservation recording command is input by a viewer, the microcomputer 8 recognizes this and stores a flag state in an internal register. do.

The microcomputer 8 first detects an on / off state of the power supply. When the power is on, the microcomputer 8 does not detect the reserved recording state and performs normal TV output. In fact, displaying the reservation recording status at this time is impossible because the previous status cannot be detected.

If the power is off, the microcomputer 8 checks whether there is a reservation recording set by the viewer. This can be confirmed by reading the reservation recording setting data (TI-REC flag) from the memory unit. If reserved recording is set, the microcomputer 8 sets the Ti-REC flag to 1 and stores it in its own memory. If the reservation recording is not set, the microcomputer 8 sets the display flag to 0, which is also stored in its own memory.

As described above, when the Ti-REC flag is 1, the microcomputer 8 compares the current time (REAL TIME) with the reserved recording setting time (Ti-REC TIME) using a clock built therein. As a result of the comparison, if the present time (REAL TIME) = reserved recording setting time (Ti-REC TIME), the microcomputer 8 outputs a control signal to perform the reserved recording.

This control signal is transmitted to the video deck section 9 and the video processing section 10, and also controls the tuner section 1 to select a channel for which reservation recording is set. The broadcast signal tuned by the tuner section 1 is modulated by the IF amplifier section 2 and then output as R, G, B signals and sound signals from the main IC section 3.

In response to a recording command from the microcomputer 8, the video processing unit 10 receives the video signal and the audio signal from the main IC unit 3, processes the video signal and the audio signal, and then inputs the video signal to the video deck unit 9. The video deck unit 9 stores image and sound signals on the video tape. When the current time reaches the recording end time, the microcomputer 8 outputs a recording stop command to stop the recording. When the recording process is completed, the microcomputer 8 waits for the power-on command to be input.

When the power-on input key is detected in this standby state, the microcomputer 8 turns on the power and detects the display flag state stored in the internal register. As described above, when the reservation recording is performed, the display flag state is 1, and the microcomputer 8 reads this and displays a text signal indicating that the recording is completed on the CRT 5. These characters can be, for example, a letter containing information such as the reservation recording has ended or the reservation recording has been completed at 10 pm on October 10, 1996. Although not shown, these characters can be easily displayed using the OSD generator.

After the character is displayed, the microcomputer 8 normally outputs the broadcast signal received through the tuner unit 1.

As described above, according to the method of the present invention, when a viewer records a broadcast in a complex television without directly recording the broadcast, turning on the TV power has an advantage of informing the viewer that the reservation recording is completed.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
