Referring to FIG. 3, the video matrix switcher 200 of the present embodiment can be used in combination with a plurality of the above-described connection devices 100.

根據以上說明，當需要拼接多個顯示器300時，可使用多個上述之連接裝置100，其中每一個顯示器300與視訊矩陣切換器200之間連接一個連接裝置100。藉由將這些連接裝置100的可調電阻電路134調整成具有不同的阻值，以使這些連接裝置100的類比數位轉換器132輸出不同的識別訊號。在一實施例中，可在調整完這些連接裝置100所輸出的識別訊號後，對視訊矩陣切換器200的識別程式進行相應的設定。舉例來說，若位於第一位置的顯示器300所連接的連接裝置100所輸出的識別訊號為S1，位於第二位置的顯示器300所連接的連接裝置100所輸出的識別訊號為S2，則於識別程式中設定識別訊號S1所對應的顯示器300位在第一位置，識別訊號S2所對應的顯示器300位在第二位置。依此類推，可以設定各識別訊號所對應的顯示器300所在的位置。如此，處理單元230執行識別程式時，即可根據識別訊號而決定所要輸出至連接裝置100的影像資料，進而使各顯示器300能正確顯示出預定要顯示的影像畫面。以上是根據各連接裝置100輸出的識別訊號來設定識別程式，而在另一實施例中，也可根據預設的識別程式來設定各連接裝置100輸出的識別訊號。According to the above description, when a plurality of displays 300 need to be spliced, a plurality of the above-described connecting devices 100 can be used, wherein each of the displays 300 and the video matrix switch 200 is connected to a connecting device 100. The adjustable resistance circuits 134 of the connection devices 100 are adjusted to have different resistance values so that the analog digital converters 132 of the connection devices 100 output different identification signals. In an embodiment, after the identification signals output by the connection devices 100 are adjusted, the recognition program of the video matrix switch 200 can be correspondingly set. For example, if the identification signal outputted by the connection device 100 connected to the display 300 in the first position is S1, and the identification signal outputted by the connection device 100 connected to the display 300 in the second position is S2, the identification signal is identified. In the program, the display 300 corresponding to the identification signal S1 is set to the first position, and the display 300 corresponding to the identification signal S2 is located at the second position. And so on, the position of the display 300 corresponding to each identification signal can be set. In this way, when the processing unit 230 executes the recognition program, the image data to be output to the connection device 100 can be determined according to the identification signal, so that each display 300 can correctly display the image screen to be displayed. In the above, the recognition program is set based on the identification signal output from each connection device 100. In another embodiment, the identification signal output from each connection device 100 may be set according to a preset recognition program.
在本創作實施例中，由於視訊矩陣切換器200可根據每一個連接裝置100所輸出的識別訊號而決定所要傳輸至每一個連接裝置100所連接的顯示器300的影像資料，所以可將每一個顯示器300各自透過一個連接裝置100而連接至視訊矩陣切換器200的任一個連接埠，因此在上述設定完成後即使將傳輸線L1隨意插接到任意的連接埠，視訊矩陣切換器200依然能輸出正確的影像資料到對應的連接裝置100，藉此避免傳統電視牆因為接錯連接埠而造成顯示錯誤的問題。In the present embodiment, since the video matrix switcher 200 can determine the image data to be transmitted to the display 300 to which each of the connection devices 100 is connected according to the identification signal output by each of the connection devices 100, each display can be Each of the 300 is connected to any one of the video matrix switchers 200 through a connection device 100. Therefore, even if the transmission line L1 is arbitrarily inserted into any connection port after the above setting is completed, the video matrix switcher 200 can still output the correct one. The image data is sent to the corresponding connecting device 100, thereby avoiding the problem that the traditional video wall causes display error due to the wrong connection.
雖然上述實施例的識別訊號產生元件130是藉由調整可調電阻電路134的阻值來達到輸出不同識別訊號的目的，但本創作之識別訊號產生元件也可為其他可以調整識別訊號的識別訊號產生元件。舉例來說，請參照圖4，其為本創作另一實施例之識別訊號產生元件的方塊示意圖。此識別訊號產生元件130a包括微控制器136及調整器138，其中調整器138電性連接至微控制器136，以調整微控制器136輸出的訊號。微控制器136所輸出的訊號即為識別訊號產生元件130a所輸出的識別訊號。此外，調整器138可為指撥開關（DIP Switch）、跳線開關（Jumper Switch）或其他合適的調整器，但本創作並不以此為限。Although the identification signal generating component 130 of the above embodiment achieves the purpose of outputting different identification signals by adjusting the resistance of the adjustable resistor circuit 134, the identification signal generating component of the present invention may also be other identification signals that can adjust the identification signal. Generate components. For example, please refer to FIG. 4 , which is a block diagram of an identification signal generating component according to another embodiment of the present invention.

The signal output by the microcontroller 136 is the identification signal output by the identification signal generating component 130a. In addition, the adjuster 138 can be a DIP switch, a jumper switch, or other suitable adjuster, but the present invention is not limited thereto.

Referring to FIG. 5, the connecting device 100a of the present embodiment is similar to the connecting device 100 of the embodiment of FIG. 1. The main difference is that the connecting device 100a of the embodiment further includes an environment sensor 160 connected to the second data channel 120. The ambient sensor 160 outputs the sensing signal to the video matrix switch 200 via the second data channel 120. The video matrix switcher 200 can adjust the image data output to the connection device 100a according to the sensing signal output by the environment sensor 160, thereby further improving the image displayed by the display 300. For example, the environment sensor 160 may be a light sensor for detecting ambient light, and the video matrix switcher 200 may adjust the image frame displayed by the display device 300 connected to the connection device 100a according to the brightness of the ambient light. brightness.
在另一實施例中，視訊矩陣切換器200可先使顯示器300顯示校正影像，而環境感測器160可用以感測顯示器300所顯示的校正影像，藉以獲取各種數值。如此，能讓視訊矩陣切換器200比較感測到的各種數值與內建的標準數值之間的差異，進而調整輸出至連接裝置100a的影像資料，以補償上述差異，使顯示器300顯示的影像畫面有更佳的表現。此外，根據不同的設計需求，本創作的環境感測器160也可以是其他的種類而有不同的用途。In another embodiment, the video matrix switcher 200 can first cause the display 300 to display a corrected image, and the environment sensor 160 can be used to sense the corrected image displayed by the display 300 to obtain various values. In this way, the video matrix switcher 200 can compare the difference between the sensed values and the built-in standard values, and then adjust the image data output to the connection device 100a to compensate for the difference, so that the image displayed on the display 300 is displayed.

上述之環境感測器160輸出的感測訊號例如是數位訊號，而直接經由第二資料通道120傳輸至視訊矩陣切換器200，而不經過識別訊號產生元件130。然而，在另一實施例中，如圖6所示，連接裝置100b的環境感測器160b的感測訊號可依序經由識別訊號產生元件130b及第二資料通道120傳輸至視訊矩陣切換器200。具體而言，識別訊號產生元件130b包括類比數位轉換器132b，而環境感測器160b電性連接至識別訊號產生元件130b的類比數位轉換器132b。類比數位轉換器132b將環境感測器160b輸出的感測訊號轉換成數位訊號，並經由第二資料通道120傳輸至視訊矩陣切換器200。此類比數位轉換器132b為多通道的類比數位轉換器，而能夠處理來自環境感測器160b及可調電阻電路134的訊號。The sensing signal output by the environment sensor 160 is, for example, a digital signal, and is directly transmitted to the video matrix switcher 200 via the second data channel 120 without passing through the identification signal generating component 130. However, in another embodiment, as shown in FIG. 6, the sensing signal of the environmental sensor 160b of the connecting device 100b may be sequentially transmitted to the video matrix switcher 200 via the identification signal generating component 130b and the second data channel 120. .

The video matrix switcher 200 is connected to the first connection interface 140c via the network route L2, for example, and the chip (not shown) in the video matrix switcher 200 processes the video and audio data into a data format that can be transmitted via the network route L2. And transmitting to the V-wafer via the network route, the V-chip then restores the received video and audio data to the display 300.
綜上所述，在本創作中，由於連接裝置具有識別訊號產生元件，以經由第二資料通道而提供識別訊號至視訊矩陣切換器，而視訊矩陣切換器是根據識別訊號而決定所要輸出至連接裝置的影像資料。因此，在連接裝置與視訊矩陣切換器之間完成識別訊號的設定後，即使將傳輸線隨意插接到視訊矩陣切換器的任意連接埠，視訊矩陣切換器依然能根據識別訊號而送出所需的影像資料至對應的連接裝置，如此一來就不會影響顯示器的輸出畫面，改善了傳統電視牆因為接錯連接埠而造成的畫面顯示錯誤。In summary, in the present invention, since the connecting device has the identification signal generating component, the identification signal is provided to the video matrix switcher via the second data channel, and the video matrix switcher determines the output to be connected according to the identification signal. Image data of the device. Therefore, after the identification signal is set between the connection device and the video matrix switcher, even if the transmission line is randomly inserted into any connection of the video matrix switcher, the video matrix switcher can still send the desired image according to the identification signal. The data is connected to the corresponding connecting device, so that the output screen of the display is not affected, and the display error of the traditional video wall due to the wrong connection is improved.
