[Embodiment] Please refer to the above-mentioned figure - the X-ray conversion device developed by Xie Guanhong, one of the inventors in the following years, and has proposed the patent application, which can provide additional display devices, especially for home display devices. The plurality of input interfaces 22 are connected to connect more types of electronic devices. During the actual use of the signal exchange 20, the inventors have observed that, in particular, the signal output from the electronic device connected to the signal conversion device such as the input interface A has been received (not shown) and is positive. When the display device 3G performs the transfer of the data output by the electronic device, at this time, the user turns on another input interface (hereinafter assumed to be the input connection σ B) ± the other electronic device connected (hereinafter assumed to be the second electronic device) Device) (not shown), meaning that the user needs to switch the input interface to the input interface β. Also, the second electronic device is often an electronic device that the user currently needs to perform preferentially. This is the majority of users in daily life. The common habit. Due to the above observation by the inventor, the (four) mechanism of automatic switching is obtained, that is, the switching of the input interface to the input state changes from no signal to sorrow to signal input state (hereinafter referred to as a new signal). Input) on the input interface. Please refer to the second figure. Based on the above idea of the present inventors, the signal conversion device 4〇 is connected to the display device 3G, and the display device 3G County _ predetermined format signal, and it can perform automatic conversion of input π. In the preferred embodiment of the present invention, the job number conversion device: 0 includes-receive unit 44, - pre-measure unit 45, - switch control unit 46 An interface switching unit 47'-signal conversion unit 48 and a power supply unit 42. The display device 30 is generally configured to receive video and/or audio in a predetermined format, but there is also a specific display device that is identifiable and Receiving a predetermined format of one of several predetermined formats, or receiving more than one predetermined format at the same time. Here, to clearly illustrate the present invention, it is assumed that the display device 30 can receive and receive only one video and/or audio signal of a predetermined format. It should be noted in advance that this specification is only for convenience of explanation. It is named "control line CL, signal output line 〇l and power line pl" to distinguish three different types of signal flow. It does not represent the true wire, so it is The connection between the control line CL, the signal output line 〇L, and the power line pl and the corresponding input/output interface does not represent the actual connection method. Wherein, the power supply unit 42 receives an externally input AC AC, and passes through the 1288346 over-power line PL A to display all of the units of the display device 30 without the number of switches or optionally to the towel-units Power supply, and different currents are supplied according to the requirements of different units. The receiving unit 44 has a plurality of input interfaces 441 (a, B, C, ...), and each input interface 441 can be based on an interface. The electronic device on the input interface can input a corresponding format signal to the receiving unit, wherein the input interface 441 is an RF radio interface, an S_video interface, and a corresponding video and/or audio electronic device. The video color difference interface (such as YCbCr), the BNC interface, or the combination of multiple or multiple interfaces, may also be other suitable interface/interface groups for receiving analog signals and/or digital signals. In this case, it is assumed that the plurality of input interfaces 441 of the signal conversion device 40 are connected to a plurality of electronic devices, wherein the first electronic device (not shown) to which the first input interface A is connected is in a signal output state, and the signal conversion device 40 receives The signal output by the first electronic device is outputted to the display device; and the electronic device connected to the other input interface is not in the signal output or the signal output from the electronic device is not received by the signal conversion device 4〇. The detecting unit 45 is connected to each input interface for detecting the level of resentment of each input interface 441 to determine whether the state of each input interface 441 has changed. When the electronic device connected to the input interface 441 has no signal output to the input interface 441, the level of the input interface 441 is low. When the detecting unit 45 detects that the level state of an input interface (assumed to be the input interface B) changes from a low level to a high level, it can be determined that the input interface B has a new signal input. The switching control unit 46 determines, in the detecting unit 45, that an input interface has a new signal input, that is, the detecting unit 45 detects that the level state of the input interface B changes from a low level to a high level. Normally, an interface switching control signal is generated correspondingly to the interface switching unit 47. The interface switching control signal can be provided with an input interface 441 identification code. For example, 〇〇1 means switch to the first input interface, 010 means switch to the second input interface, and so on, the identification code of different input interfaces can be set. The interface switching unit 47 is configured to receive the interface switching control signal and switch to the corresponding input interface, so that the signal conversion 40 can receive the signal input to the input interface. For example, when the interface switching unit 47 receives the interface switching control signal with the "〇1〇" input interface identification code, according to 1288346, the above-mentioned bribe means 'switching the second input to the sigma B, so that the signal conversion device 4G can Received a signal input to input interface B.

The following method will automatically switch the interface of one of the above-mentioned signal conversion devices 4G; = apply to 彳田远 and still expand _ 职装(四)__-接接;; a === 11 1288346 The signal output by the sub-device (not shown), and the received signal is converted and output to the display device 30. In the present embodiment, the new signal input having two or more at the same time is excluded, that is, the electronic device connected to the two or more input interfaces is changed from the state of the never (four) signal to the signal conversion device 40 to the output. The status of the signal to the signal conversion device 4: Step S3G1: The detection unit 45 determines whether there is a new signal input during the predetermined time interval in the predetermined time interval by the detecting unit 45. Step S303: When the test is performed The unit 45 detects and determines that when the level state of the second input interface B changes from a low level to a high level, that is, when the second input connection σ B has a new signal input, the switching control unit 46 is connected. The control code 职, _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The location. If the interface switching unit 47 receives the identification code with the "〇1〇" input interface, it will switch to the position where the second input interface Β, and the receiving unit 44 can receive the signal input to the second input interface 。. The signal input to the other input interface will not be received, that is, the signal input to the first input interface will no longer be received. Step S307. The signal conversion unit 48 selectively converts the format signal input by the second input interface to the second electronic device into the predetermined format signal. Step S309: receiving, by the display device 30, the converted predetermined format. a signal and display information related to the predetermined format signal. In addition, when the user has a new input signal with a new input signal at the same time, the priority of each input interface 441 can be set. For example, if the first input interface is set as the interface with the highest priority, the priority correlation flag is “ 3", the second input interface is set as the interface of the second priority execution, the priority correlation flag is "2", and the third input interface c is set as the last priority execution interface, and the priority correlation flag is "Γ" Even if there are new signal inputs at the same time, the signal conversion device 40 can still determine that only one input interface 441 is added at the same time by the priority correlation of each of the input interfaces 441. Moreover, although it is assumed that the signal conversion device 40 has previously received the signal input to the first input interface, the automatic interface switching method described above still applies to the case where the input is not received to any of the input 12 1288346 interfaces. This is no longer a narrative. • [Simple description of the diagram] The first picture shows the signal of the prior art.
