The video signal switching device that inputs the device as an input source. [Prior Art] 凊 Refer to "1", which is a schematic diagram of a conventional audio-visual input device (1). As shown in the figure, at one end of a television 10, a set is provided. Group audio and video signal input terminals, usually one of which is the video signal input terminal 101, and the other is the audio signal input terminal 101'. Moreover, in practical use, the television 10 will be connected to more than one audio and video input device 11 separately. For example, a DVD player, an audio device, etc.; as shown in the figure, the video input device u is provided with at least one set of audio and video signal output terminals (including an image signal output terminal 1U, and an audio signal output terminal). m'), between the image signal input terminal 101 and the image signal output terminal U1, a signal line 12 is connected to each other, and between the audio signal input terminal 1〇1 and the audio signal output terminal 101', another group is disposed. The signal line 12, through the connection of the signal lines 12 and 12', can output the audio and video signals of the audio and video input device U to the display of the television 1; as above, the general large television or the display for output The screen usually has an array of signal terminals to be connected. However, if it is a small TV or display screen, there is usually only one set of signal terminals that can be connected. If the user wants to use other audio and video devices, the original must be connected to The video signal input terminal ιοί of the TV, and the signal line (12, 12') of the audio signal input terminal 101 are removed, and then connected to the signal line exclusive to other audio-visual devices, so that the signal line is easily replaced. The internal wire is broken, or the image signal input terminal 101 and the sound signal input terminal 1〇1, the terminal hole is loose, and the like. Please refer to "Fig. 2", which is a schematic diagram of another conventional audio-visual input device (2). As shown in the figure, in the television 10 and two audio-visual devices (the first audio-visual input device 13, the first Between the audio and video input devices 14), a video signal output terminal (131, 141) of the two audio-visual devices (the first audio-visual input device 13 and the second audio-visual input device 14) is connected to the signal tapping box 15', and The audio signal output terminals (132, 142) are respectively connected to the video signal input terminal 151 of the signal tap box 15 and the audio signal input terminal 152 through the two signal lines (12, 12'), and then through the signal tap box. The video signal output terminal 153 and the audio signal output terminal 154 of the 15 are connected to the video signal input terminal 101 and the audio signal input terminal 101' of the television 10 via a set of signal lines 121 and 121'' for transmitting video and audio signals, and Through an operation switch (not shown in the figure) on the signal tap box 15, the audio and video signals of the video input device to be displayed and displayed are switched. Referring to "3rd picture", the figure shows a Knowing audio and video No. line layout diagram, as shown in the signal distribution box 15, wherein 'the image signal input terminal 151 and the sound M377812 signal input terminal 152 are connected to the tap box 15, respectively connected to a first signal line segment 1511 And a second signal line segment 1521, and the image signal output terminal 153 is connected to a first signal output line segment 1531, and the other signal output terminal 154 is connected to a second signal output line segment 1541. The signal line segment 1511 and the second signal line segment 1521 are electrically connected to the first signal output line segment 1531 and the second signal line respectively.
路段1521與第二訊號輸出線路段1541形成一訊 號導通的線路，然，由圖示中可清楚看出，此種 訊號分接盒15雖然可以滿足同時連接多組影音裝 置的問題，但其同一訊號線路段（如第一訊號線路 丰又1511或第一訊號線路段15 21 )，係等同於常態 性與多組訊號線（12、12，）呈訊號導通的連接了 雖可透過控制而達成選擇一組訊號進入，但無論 選擇使用哪一組訊號線作為輸入源，另一組未使 用的線路仍舊會因分配阻抗的問題，干擾正在使The road segment 1521 and the second signal output line segment 1541 form a signal-conducting line. However, as can be clearly seen from the figure, the signal tap box 15 can satisfy the problem of simultaneously connecting a plurality of groups of audio and video devices, but the same The signal line segment (such as the first signal line 1511 or the first signal line segment 15 21) is equivalent to the normality and the signal connection of the plurality of signal lines (12, 12,). Select a group of signals to enter, but no matter which group of signal lines are selected as the input source, another set of unused lines will still be caused by the problem of impedance distribution.
