Description of the Invention: [Technical Field] The present invention provides an audio-visual playback system, and more particularly to an audio-visual playback system having an auxiliary wiring function. [Prior Art] With the rapid development of information and the advancement of multimedia playback technology, various audio-visual equipments have been applied to provide information and sensory information for images and sounds. However, with the rapid development of audio-visual technology, images of different signal specifications And the sound signal transmission and came into being. However, for the average consumer, the image and audio signal transmission interface of such a variety of different signal specifications often confuse the wiring. For example, for the first time, you want to connect a TV device and a recording and playback device (such as VCD player, DVD player, DVR). Users of this class often do not know how to connect the TV device and the recording and playback device. It is often used to design a variety of video and audio connectors on the TV device and the recording and playback device. For example, the video signal is divided into composite TV signals (cVBS). , composite signal), S-video video signal, high-resolution video (YPbPr) signal, etc., causing the user to know which connector should be connected, and because the user often does not understand the output and input connection definition, It is often the case that the wrong line is connected. 'It takes a lot of time to try it correctly or you need to ask the experts to connect correctly'. Plus, if the manual is lost, the wiring work becomes difficult. The use of the playback device is quite inconvenient. The invention claims the disclosure of the invention relates to an audio-visual playback system with an auxiliary wiring function, which comprises a plurality of connection interfaces for connecting at least an external device and an input interface for selecting the complex number. a connection interface to be connected to the external device, a display device for displaying connection information of the plurality of connection interfaces, and a logic unit for controlling the display device according to the connection interface selected by the input interface Display the relative • connection information. A plurality of connections of the device are disclosed in the patent application scope of the present invention. A method for assisting the wiring function is disclosed. The method includes the following (4): selecting one of the connection interfaces in the video playing surface, and according to the selected connection interface. Displaying the corresponding connection information. The scope of the claimed patent is also disclosed in a video playback device comprising the following steps: selecting the interface for the video playback interface: the second = a plurality of connection interface options, and when such Connect information. When it is broken or taken, the corresponding display of the display device is displayed in the display device: it is characterized by the use of video and audio to display the secret surface-line connection action, so that the user can easily connect In the case of the wrong line, the wiring work is completed. In addition, since 6 1307468 s dynamically teaches the user to perform the wiring action, whether the wiring is successful or not can be known through an interactive manner, which is a humanized guiding wiring method.

Step 106: Determine whether the connection selected in step 1〇4 is plugged in, otherwise Step 108 is performed, and if yes, step 11 is performed. Step 108·· When the connector selected in step 1〇4 is not plugged in, the connection diagram corresponding to step 1〇4 in FIG. 7 is corresponding. The display prompts the wiring in a blinking manner. Step 110: When the connection selected in step 104 is inserted into the connector, the diagram corresponding to the connection jt皋 selected in step 104 in the 7th Lutu diagram stops blinking. The above steps are explained in detail. First, the user can view the face shown in FIG. 6 through the display device 60, and use the input interface % to select the desired interface to play the movie or program through the display display interface mode. To input or output the connection format of the signal, when the user φ determines the corresponding connection, the face shown by the display device 60 will jump to the face of the figure. For example, in the step 102 and step 1 In the case of 4, when the user selects the S terminal connection under the video option, the logic single will be based on the corresponding input connection interface 16; the s terminal is connected to the 埠6 (and the 3 playback system 10 needs to be connected by the input interface 16) The signal from the connection switch 64 of the s terminal connection 蟑 26 input signal is judged to be the terminal connector of the 8-terminal serial scale 26. The S-terminal connection 埠 26 of the field input connection interface 16 is not inserted with the connector 11 1307468 : 1 = display device 60 displays the S terminal connection of the video playback system 以及 26 and the recording and playback f 34 rain out connection interface 38 S terminal connection #, play shadow only 昧 丄 丄 ^ ^ Station An early 42 (々曰Play the system 10 sub-connection 2 _ 34 output connection interface% of the S-end soap 42 receiving signal) flashing icon, the line is inserted into the video playback system 1G wheel user ^ user will be around the bee 26 and the device 34 The heart connection ^ terminal connection 42.

This is limited to the figure that tells the user whether the wiring is wired or not. Using other image display methods or sound prompting methods is when the user accidentally picks up the wrong connection, the original, 'change, must wait until the user connects successfully, will change 12 1307468 from the original prompt to another Prompt mode, this provides a confirmation mechanism. Similarly, the present invention can also be used when the connector 埠 is not connected to the connector, the logic unit 62 controls the display device 60 to display the connection 埠 to stop the flash of the flash, and when the connector is connected to the connector, the logic unit 62 The control device 6〇 displays a graphical representation of the flashing of the port. The principle of the connection of the other specifications of the selected video or program recording φ option is the same as the above example, and therefore will not be described in detail herein. The video and audio playback system of the present invention uses the on screen display (OSD) of the display screen to guide the use of the 耆 to perform the wiring step by step, so that the user can easily and easily encounter the wrong line. In this case, the wiring work is completed. In addition, since the user is dynamically taught to perform the wiring operation, whether the wiring is successful or not can be known through an interactive manner. This is a humanized guiding wiring method. The above description is only the preferred embodiment of the present invention. The equivalent variations and modifications made by the application of the present invention should be within the scope of the invention.
