Especially from a future perspective When considering the broadcasting of television, although the ground wave analog broadcasting is currently the main body, the worldwide ground wave digital broadcasting has been gradually popular since 1998, and will be on par with the ground wave analog broadcasting in a few years. After that, Then the terrestrial wave analog broadcasting will be abolished, and television broadcasting will form a comprehensive digital broadcasting of terrestrial waves. In this case, in the transition period from the transition from analog to digital broadcasting, the correspondence in the television receiver is a kind of Feel free to cope. Like the situation of the conventional TV receiver, only consider the connection of DTV STB and use only the combined video input terminal There are times when the following is extremely inconvenient to use. In other words, when using the TV receiver's remote control and using the DTV STB, you must use the TV receiver's remote control to make selective input to the combined video input terminal. Furthermore, the DTV channel is selected by using the STB remote control for DTV. That is, two remote controls must be operated separately. Also, if the STB for DTV is connected incorrectly or the STB for DTV is not connected correctly, In the case of continuity, a valid first combination video signal will not be supplied. As a result, the correct image will not be displayed on the display, or the signal will completely disappear (Black out). In this case, the user will be confused and mistakenly believe that it is Device failure, which may lead to a state of inability to operate correctly. {Please read the precautions on the back before filling in the spirit) \ its -------- order --------- line-Ministry of Economy Printed by a member of the Intellectual Property Bureau and Consumer Cooperatives.

Description of the invention (18) Video signal exchange device Vspl, briefly state the specific actions below. The user operates the remote control and sends an instruction to the combined video signal exchange device Vspl related to the program content provided from a specific combined video signal source. For example, when the conventional video recording and playback mechanism is used to watch and watch NTSC system programs, the control mode of the image signal switcher 3 is of course to select the output of the NTSC color difference signal demodulator 2 and output it to the conversion separator 4 and the RGB processor. 5. After the content is viewed by the video recording and playback agency and the user wants to watch the digital broadcast, it is necessary for the user to re-select the combined video signal source with the remote control for the desired broadcast object. In particular, a large number of display devices make the selection of the video input to be a toggle circuit. Therefore, to select the turn from the desired combined video signal source, it is necessary to press the input selection key several times. On the other hand, in this embodiment, after the user selects the STB for DTV with the remote control, if the user presses a button corresponding to the desired function, the designated digital code Src of the same function is transmitted to the remote wave receiver 12. The remote wave receiver 12 receives the digital code Src and outputs it to the first controller 11A. The first controller ΠA compares the content of the received remote control digital code src with the remote control code stored in the STB remote control code table 13. Next, when the content of the digital code Src is consistent with one of the remote control codes, the first controller 11A immediately outputs the high-level selection signal sw to the image signal switch 3 to form alternate selection from the input terminal 1.

When the aspect ratio scale 3 is 4: 3 (letter row), proceed to step s31〇. In step S306, the normal NTSC aspect ratio is 4: 3, so it is 16 : The aspect ratio of 9 adjusts the vertical deflection angle or horizontal deflection angle of the display 6 according to the state of the aspect ratio of the display 6, and then ends the processing. At step S308 ', since the aspect ratio is 4: 3, there is no difference between the aspect ratio of ordinary NTSC and the situation of step S306. The processing is terminated without changing the vertical deflection angle and the horizontal deflection angle of the display 6. In step S310, the aspect ratio is 4: 3, so it is the same as that in step S308, and does not change the vertical deflection angle and the horizontal deflection angle of the display 6, that is, the end processing. Next, referring to Fig. 8, the adjustment of the aspect ratio of the display 6 in step S306 will be briefly described.
