How to watch TV reservation using G-Code

The present invention relates to a TV reservation viewing method using a G-code. More specifically, when a broadcast program to be watched is set through a G-code, the TV program can be watched at another time even if the TV is turned off or the TV is turned off. The present invention relates to a TV reservation viewing method using a G-code that allows a TV to be turned on to watch a reserved broadcast channel.

In general, a TV system refers to a video display device that receives broadcast channel signals transmitted to a plurality of broadcast stations and displays the received broadcast channel signals as image data. In recent years, a TV broadcast system transmits cable and satellite broadcasts together. With the user getting wider by that width of viewing.

Then, referring to FIG. 1, a TV system including a tuner circuit unit 70 for receiving and tuning multi-channel TV broadcasting signals input through an antenna and a tuning function of the tuner circuit unit 70. A microcomputer 78 for controlling overall operation of the system, a voice IF amplifier 71 for amplifying an intermediate frequency signal of a high frequency information signal tuned by the tuner unit 70, and the voice IF amplification. A detector 72 for demodulating the voice signal amplified by the intermediate frequency in the unit 71, a voice signal processor 73 for processing the voice signal demodulated in the detector 72 at an audible frequency, and the tuner An image IF amplifier 75 for amplifying an intermediate frequency signal of an information signal of high frequency tuned by the circuit unit 70 and an image for processing a video signal amplified at an intermediate frequency in the image IF amplifier 75. It consists of a signal processing unit 76.

The microcomputer 78 is connected to a key input unit 79 for setting functions such as channel selection and volume according to TV viewing.

On the other hand, referring to the operation of the conventional TV system configured as described above, for example, if the user wants to watch the TV broadcast signal, the corresponding channel is set through the key input unit 79. The microcomputer 78 recognizes this and inputs the control signal according to the station selection to the tuner circuit unit 70. Then, the tuner circuit unit 70 tunes a channel signal set by a user among the TV broadcasting channel signals of several channels input through the antenna, and the tuned high-frequency channel signal is a voice IF amplifier 71 and an image IF amplifier unit. 75 are each transmitted separately.

That is, the voice signal of the TV broadcast signal received by the tuner circuit unit 70 is applied to the voice IF amplifier 71 and amplified to an intermediate frequency, and the voice signal amplified by the intermediate frequency is demodulated by the detector 72. And the audio signal processor 73 is applied. At this time, the voice signal processor 73 processes the input voice signal according to an audible frequency and applies the voice signal to the speaker 74, so that the voice of the tuned broadcast channel is output through the speaker 74.

At the same time, the video signal among the TV broadcast signals received by the tuner circuit unit 70 is amplified to the intermediate frequency by the image IF amplifier 75, and the image signal amplified by the intermediate frequency is applied to the image signal processor 76. . Then, the video signal processor 76 processes the input video signal through color separation and luminance separation, and applies the same to the CRT 77 as an RGB color signal, thereby allowing the user to output the audio signal through the speaker. You can watch the screen output through.

However, such a conventional TV system can freely watch a desired broadcast channel by selecting a channel through a key input unit, and even if the TV is connected to a TV system, the reserved time and its reserved channel are set and the TV is powered off. Although it is possible to record a reserved program through V-CAL, there is a problem in that the user cannot watch a desired program unless the user knows the program broadcast time of another channel which is broadcast in real time while watching another channel.

Accordingly, the present invention has been invented to solve the above-mentioned problems. When the broadcast program to be watched is set through the G-code, the TV power is set at the set time even if the TV program is being watched or the TV power is turned off. An object of the present invention is to provide a TV reservation viewing method using a G-code for viewing a reserved broadcast channel.

In order to achieve the above object, the present invention provides a method for determining whether to reserve a time and a channel according to a G-code while tuning a broadcast channel and watching a TV. (B) judging whether the reservation according to the code has been set and determining whether the preset reservation time has been reached by counting the set time, and determining that the reservation time set by the G-code has been reached as a result of the determination in step (b) (C) performing a power control operation according to the TV power on / off state, and in this step, the channel is determined while the TV power is on, and if the current channel is not a reserved channel, the channel is switched to a reserved channel to perform a broadcast program.

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

The TV system to which the present invention is applied includes a reservation setting unit 2 for setting a viewing reservation mode using a G-code and a reservation setting signal input from the reservation setting unit 2 as shown in FIG. The microcomputer 3 which controls the overall TV operation including the counter operation and the channel switching operation according to the mode, and the OSD unit which applies the screen for setting the reservation to the video signal processor 6 according to the control signal of the microcomputer 3. (8), a tuner unit 4 for receiving and tuning multi-channel TV broadcasting signals input through an antenna according to the control signal of the microcomputer 3, and a high frequency tuned by the tuner unit 4; Image IF amplification unit 5 which separates a video signal from the information signal and amplifies it at an intermediate frequency, and processes the video signal amplified by the video IF amplification unit 5 through color separation and luminance separation to perform R, G A video signal processor 6 for outputting a color signal of B, The video signal processor 6 includes a CRT 7 for displaying the video signal separated into R, G, and B to the outside.

In addition, the TV according to the present invention is a voice IF amplifier 9 for separating the amplified voice signal from the information signal of the high frequency tuned by the tuner 4 and amplifying to an intermediate frequency, and this voice IF amplifier 9 A detection unit 10 for demodulating a voice signal amplified at an intermediate frequency in the step 10, a voice signal processing unit 11 for processing the voice signal detected by the detection unit 10 at an audible frequency, and the voice signal processing unit 11 Speaker 11 for outputting the signal processed in the outside to the outside is provided.

Next will be described the method of the present invention applied to the TV consisting of the above configuration.

As shown in FIG. 4, the present invention proceeds to a TV viewing step S2 of watching a broadcast program according to channel setting in an initial state S1. At this time, the TV viewing step (S2) proceeds to the reservation setting determination step (S3) for determining whether the reservation through the G-code is set during the TV viewing. At this time, if it is determined in the reservation setting determination step (S3) that the program reservation is set through the G-code, the operation proceeds to the timer operation step (S4). In the timer operation step S4, the counter operation according to the reservation time included in the G-code is performed and the process proceeds to the reservation time determination step S5.

Therefore, when it is determined in the reservation time determining step (S5) that the current time corresponds to the preset time, the process proceeds to the TV power determining step (S6). Therefore, when the TV power is determined to be in the OFF state as determined in the TV power determination step (S6), the TV power is turned on through the TV power on step (S7) to the TV channel determination step (S8), and the TV power source If it is determined in the determination step S6 that the TV power is turned off, the process proceeds directly to the TV channel determination step S8. Therefore, if it is determined in the TV channel determining step (S8) that the current TV channel is sold as a reserved broadcast channel, the process proceeds directly to the reserved channel viewing step (S10) to watch the broadcast program of the reserved channel and ends the present loop.

On the other hand, if it is determined in the TV channel determining step (S8) that the current TV channel is not a reserved broadcast channel, the process proceeds to the broadcast channel switching step (S9). Then, in this broadcasting channel switching step (S9), after displaying a guide indicating that the current broadcasting channel is switched to the reserved broadcasting channel, the channel is changed to the reserved broadcasting channel and proceeds to the reserved channel viewing step (S10) to broadcast the reserved program. Watch and end this loop.

That is, when the viewer sets the reservation setting unit 2 to the on state, the setting signal corresponding thereto is input to the microcomputer 3. At this time, the microcomputer 3 applies a predetermined control signal to the OSD unit 8. Therefore, the OSD unit 8 applies the pre-stored display data to the image signal processing unit 6, so that the first setting screen shown in FIG. 3A is output to the CRT 7.

At this time, the first setting screen allows the user to respond whether to set the program reservation according to the G-code, and the microcomputer 3 recognizes that it is normally set by pressing an arbitrary key in the key input unit 1.

That is, when the user inputs the G-code through the key input unit 1 according to the reservation, the signal corresponding thereto is input to the microcomputer 3. Then, according to the control signal of the microcomputer 3, the OSD unit 8 applies the program information corresponding to the currently input G-code to the image signal processing unit 6. Therefore, a second setting screen as shown in Fig. 3B is output on the screen of the CRT 7.

In this case, it is preferable that the second setting screen is removed from the broadcasting screen when the erasing selection key is set through the user's key input unit 1 or the set time (about 10 seconds) elapses.

On the other hand, when a program is reserved through the G-code, the G-code includes channel and time data, and the microcomputer 3 counts the reservation time through the built-in timer. At this time, when the current time reaches the reservation time corresponding to the G-code by the count operation by the timer, the microcomputer 3 determines whether the broadcast channel tuned by the current tuner unit 4 is a reserved channel. At this time. If the broadcast channel received from the tuner unit 4 is not the same as the reserved channel, the OSD unit 8 displays program information corresponding to the currently input G-code according to the control signal of the microcomputer 3 and the image signal processor 6. Is applied. Therefore, a third setting screen as shown in Fig. 3C is output on the screen of the CRT 7. The tuner unit 4 switches to the reserved broadcast channel by the control signal of the microcomputer 3 and transmits the video and audio signals according to the video IF amplifier 5 and the audio amplifier 9, respectively. Is authorized.

Here, the voice signal of the TV broadcast signal received by the tuner 4 is applied to the voice IF amplifier 9 and amplified to an intermediate frequency, and the voice signal amplified by the intermediate frequency is demodulated by the detector 10. It is applied to the audio signal processor 11. At this time, the voice signal processor 11 processes the input voice signal according to an audible frequency and applies the voice signal to the speaker 12, so that the voice of the tuned broadcast channel is output through the speaker 12.

At the same time, the video signal among the TV broadcast signals received by the tuner 4 is amplified by the video IF amplifier 5 at an intermediate frequency, and the video signal amplified by the intermediate frequency is applied to the video signal processor 5. . Then, the video signal processor 5 processes the input video signal through color separation and luminance separation, and applies the same to the CRT 7 as an RGB color signal so that the user can output the CRT 7 together with the audio output through the speaker. You can watch the screen output through.

As described above, according to the present invention, a program is reserved through a G-code to automatically switch to a reserved channel if the currently viewed channel is not a reserved channel, and automatically when the scheduled time is reached even when the TV power is off. By turning on the power and tuning to the reserved channel, the viewer can be sure to watch the reserved program.
