BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a channel setting apparatus by simultaneous setting of television / wired broadcasting. In particular, the present invention relates to a channel setting apparatus that stores memory in the order of channels received without distinction of a broadcasting mode during channel selection of television broadcasting and cable broadcasting. In the case of overlapping channels of a broadcast, the present invention relates to a channel setting apparatus for displaying on a screen by an on-screen display.

In general, a television is divided into a color signal, a contrast signal, and a synchronization signal, which are video signals. When a contrast signal and a color signal are mixed and converted, an image is formed in a CRT. The synchronization signal is a signal of an image transmitted from a broadcasting station, and one picture is represented by 525 strands, which may be referred to as a converter necessary for preventing each of these lines from being disturbed on the CRT.

In other words, it is the TV screen that we are seeing that is transmitted as a line and shown as a picture. The number of screens sent to the receiver in one second by the broadcasting station is 30, and the number of lines (scanning lines) that make one screen in one second is drawn with 525 strands × 30 scenes = 15,750 strands. Therefore, since the contrast of the same place changes every 1/30 second, the movement can be fully expressed.

In short, the basic principle of television is hidden in transmission and reception. The first process is to divide a single image into pixels of the minimum unit, photoelectrically convert one by one in a certain order, and then send them one by one. Then, the receiving side, on the contrary, converts light in electricity, and thus becomes a structure of the original image. This process is called an injection, and the injection is repeated one horizontal scan from the upper left to the lower right of the screen.

This is the process by which the program produced by the broadcasting station can be seen in the same place in the viewer's desired place.

Therefore, a general television receiver includes an antenna 1 for receiving an airwave broadcasting signal, a tuner 3 for tuning the broadcast signal received by the antenna 1, and the tuner 3 as shown in FIG. The intermediate frequency amplifier 3 for amplifying the intermediate frequency signal outputted from the) and the intermediate frequency signal outputted from the intermediate frequency amplifier 3 are converted into an image intermediate frequency signal PIF and an audio intermediate frequency signal SIF. An image / audio frequency signal separator 4 comprising a surface acoustic wave filter for separating and an audio detector 5 for detecting an audio signal from an audio intermediate frequency signal separated and output from the image / audio frequency signal separator 4 And an image detector 6 for detecting an image signal from an image intermediate frequency signal output from the image / audio frequency signal separator 4.

In addition, the viewer receives a remote control (7) for controlling the output volume and channel switching or other devices, and the infrared signal transmitted from the remote control (7) to convert it into an electrical signal and output it A receiving unit 8 and a control unit 8 for controlling the entire apparatus in accordance with the code signal input from the receiving unit 8 is composed of.

And a voice processing unit for performing voice processing such as bass, treble, and volume according to a control signal from the controller 9 with respect to the voice signal output from the voice detector 5 ( 10) and a voice amplifier 11 for amplifying and outputting the voice signal processed by the voice processor 10 to the speaker 12.

In addition, by outputting predetermined on-screen display pattern data corresponding to the corresponding control signal in accordance with the predetermined control signal from the control unit 9 to inform the user of the overall operation of the device such as channel switching or volume control. Color, tint, brightness, etc. according to a control signal from the controller 9 for the OSD generator 13 and the image signal output from the image detector 6. An image processor 14 for outputting R, G, B (red, green, blue; red, green, blue) and luminance (Y) signals corresponding to an image signal, and outputting from the image processor 14 A mixer 15 for mixing and outputting the R, G, B and luminance Y signals and the R ', G', B 'and on-screen display blanking signals Y' outputted from the OSD generator 13; And driving the CRT 17 based on the R, G, B and luminance (Y) signals output from the mixer 15. The key consists of the CRT driver 16.

That is, in the television having the above-described configuration, when the viewer selects a channel with a plurality of selection buttons configured on the remote controller 7 or selects the volume, the image quality or the function of the voice, the tuner 9 performs the tuned broadcast. The channel broadcast signal tuned according to the control is detected by the voice detector 5 and the image detector 6 and output through the CRT 17 and the speaker 12.

In addition, since March 1, 1995, cable television (CATV) has begun to air in Korea, and this makes TVs provide infinite information.

Cable television refers to a broadcast that can transmit and receive a program by connecting to a broadcast station using a coaxial cable or an optical cable. In contrast, broadcasts transmitted from a plurality of broadcast stations transmit image information wirelessly, whereas cable broadcasting subscribes through a cable. The cable TV is called a comprehensive cable broadcasting system.

Originally, cable television receives airwaves transmitted from broadcasting stations by installing a repeater or antenna for receiving airwaves in a high mountain, such as a high mountain, and receives the received broadcast signals by cable. Or, it was to transmit television image of clearer picture quality by relaying airwaves to subscribers such as areas where airwaves are not received cleanly by interference.

In the beginning, it was merely a broadcast, but as the subscribers' desire for the sights increased, wired broadcasting stations producing and transmitting their own programs were expanding day by day.

Cable TV has been spotlighted as an important delivery and information medium in the information age in that it can supply various programs through multiple channels. Cable TV is a specialized channel with unique programs for each channel. You can watch.

For example, subscribers can provide a variety of information through television by watching news channels for those interested in current affairs, sports channels for sports or leisure, and movie channels for movie enthusiasts. In addition to being able to receive, it is a big advantage in that viewers can actively select and select their own channels.

Moreover, cable television has a wide range of applications in the information service field, and can handle home shopping and banking services by connecting to computers, including crime prevention, disaster prevention and automatic meter reading.

However, in case of receiving airwave broadcasting and cable broadcasting by connecting a wired cable to the television receiver, an automatic channel setting apparatus is used to automatically tune the channel transmitted by the TV broadcasting and the cable broadcasting by the remote controller so that only the tuned channel is received. There is a case.

That is, only signals that are currently received from television and output video and audio from the CRT and the speaker above a certain level are automatically tuned and stored in the memory, so that only the channels tuned by the channel up / down are output.

Therefore, when a viewer purchases a television for the first time or changes the position of the television, or when a new channel is subscribed to a specific channel, only the received channel should be tuned using the automatic channel setting device. At this time, the viewer automatically has selected the airwaves received from the television in the television broadcasting mode, and then the viewer has to troubleshoot only the cable broadcasting received from the cable in the cable broadcasting mode.

In addition, in a case where the broadcast tuned in the television broadcast mode and the cable broadcast mode overlaps with the tuned channel in the TV broadcast mode and the cable broadcast mode, there are cases where two channels of the same broadcast are unnecessarily stored.

The present invention has been made in view of the above-described disadvantages, and the memory is stored in the order of the channels received during the channel selection of the TV and cable broadcasting without distinction of the broadcast mode, and the channels of the memory and the TV broadcasting and the cable broadcasting overlap. An object of the present invention is to provide an automatic channel setting apparatus having a channel setting function for displaying on a screen by an on-screen display.

The above object is a television receiver having video / audio processing means for processing video and audio signals detected on the basis of a broadcast signal received by an antenna, wherein the selection means is provided with a setting button for the viewer to tune into a channel. And a TV / wired broadcasting tuning memory unit for storing the channels of the TV broadcasting and the cable broadcasting selected by the selection means, and the control data for switching to the cable broadcasting or the TV broadcasting when the TV broadcasting or the cable broadcasting is completed. A control data storage unit for storing the data, a mode switching unit for switching a mode to cable broadcasting or television broadcasting upon completion of the tuning, and an operation of channel tuning mode from the selection means, and the mode switching unit for TV broadcasting and cable broadcasting modes. To tune the tuner to tune only the airwaves By comprising control means for outputting a control signal to store the group TV / CATV channel selection memory can be achieved.

That is, according to the present invention having the above-described configuration, when the viewer selects the TV and cable broadcasting channels when the cable broadcasting or the cable broadcasting channel is connected to the television, the broadcasting mode is automatically switched and the broadcasting mode is automatically switched. By allowing one channel to be memorized, it is possible to enhance the viewer's convenience by improving the function of the television receiver.

The control unit 120 tunes the tuner 1 to tune the TV broadcast and the cable broadcast to each channel order, and when the channel tuned to a predetermined level or more is satisfactory, the control unit 120 transmits the tuner 1 to the TV / wired broadcast tuning memory unit 130. Save it. At this time, the television broadcast is preferentially or selectively tuned, and after the television broadcast is tuned, the channels of the cable broadcasting are automatically tuned and stored sequentially. The television broadcasting and the cable broadcasting mode switching are performed by the control unit 120 in the mode switching unit 140.

When the channel transmitted from the same broadcasting station is selected among the channels stored in the TV / Cable broadcasting channel selecting memory unit 130, the control unit 120 stores the control data of the controller in the OSD. Data for controlling the generator is output to indicate that the channel is tuned in both television and cable broadcasting on the CRT 17 through the image processor 14.

Therefore, on the CRT 17, the channels selected by the viewer are output in the order of the channels tuned in without order of television broadcasting or cable broadcasting. Therefore, viewers can watch selected channels based on channel order without any switching from TV broadcasting to cable broadcasting or cable broadcasting to television broadcasting, thereby improving convenience.

Referring to the flowchart of channel setting of television / wired broadcasting of FIG. 3, the control unit 120 reproduces a broadcast signal of a normal television in a state where the television receiver is powered on. (S201). In this case, when a setting button (not shown) is input from the remote controller 100, the control unit 120 determines whether a setting button for channel selection is input (S202), and controls the tuner 1. Tuning of the channels sequentially or selectively received from the mode switching unit 140 of the television broadcasting and the cable broadcasting (S203) is performed. The channel tuned in this way is stored in the TV / wired broadcasting tuning memory 130 (S204).
