Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problems that in the prior art, due to the fact that a plurality of signal sources are all connected to the same display device, signal source selection is disordered, and the display device cannot display a signal source which a user wants to display.
The present invention will be described in detail with reference to specific examples, but it is to be understood that the present invention is not limited to the examples.
Referring to fig. 1, in an embodiment of the present invention, a specific flow of a method for selecting a signal source of a display device is as follows:
step 100: and the display equipment traverses each interface which is currently connected with the signal source, and screens out all interfaces with input signals.
Preferably, in order to avoid the problem that the signal source selection is disordered due to the fact that the plurality of interfaces have input signals after the display device is turned on, and to ensure that the display device can automatically display the signal source which the user wants to display, the user needs to set priority configuration information for each interface of the display device in advance, and then connect the signal source with the high demand degree to the interface with the high priority and connect the signal source with the low demand degree to the interface with the low priority according to the demand degree of the signal source.
The signal source in the embodiment of the present invention may be, but is not limited to: any one or any combination of a set-top box, a game player and a video disc player.
Specifically, when step 100 is executed, the following steps may be adopted, but not limited to:
firstly, the display device monitors the voltage values of the interfaces in real time.
Then, when the display device determines that the voltage value of any one interface is within a preset voltage range, the display device judges that an input signal exists in any one interface.
And finally, screening all interfaces with input signals by the display equipment in the mode.
For example: the display device a has 4 interfaces, which are interface 1, interface 2, interface 3 and interface 4, and the corresponding priority configuration information is: priority 3 (highest), priority 2, priority 1, priority 0 (lowest).
According to the degree of the user's demand for each signal source, the user connects the set-top box 1 (signal source 1) with the highest degree of demand to the interface 1, connects the game machine (signal source 2) to the interface 2, and connects the video disc player (signal source 3) to the interface 3, and the interface 4 is not connected with any signal source (i.e. the interface 4 is an idle interface).
After the display device A is started, the voltage values of the 4 interfaces (the interface 1, the interface 2, the interface 3 and the interface 4) are monitored in real time, the display device A judges that the input signal exists in the interface 1 when the voltage value of the interface 1 is monitored to be within a preset voltage range, the method is continuously adopted, each interface of the display device A is traversed, and the input signal also exists in the interface 2 and the interface 3.
Step 110: the display equipment respectively determines the current priority of each interface with the input signal according to preset priority configuration information, wherein the current priority of the interface indicates the demand degree of a user on a signal source connected with the interface.
For example: continuing to use the above example, after the display device a determines that the input signal exists in the interface 1, the interface 2, and the interface 3, according to the priority configuration information of each interface preset by the user, it determines that the current priority configuration information of the interface 1 is: priority 3, the current priority configuration information of interface 2 is: priority 2, and current priority configuration information for interface 3 are: priority 1.
Step 120: and the display equipment selects the signal source connected with the interface with the highest current priority for display.
For example: continuing with the above example, the display device a determines that the current priority (priority 3) of the interface 1 is the highest, and selects the set-top box 1 connected to the interface 1 for display.
Further, when the user wants to switch other signal sources for displaying, the following methods can be adopted, but not limited to:
the first mode is as follows: if the other signal sources (i.e. the signal sources which the user wants to switch) are connected to the interfaces of the display device, all the interfaces with higher priority than the interfaces connected with the other signal sources (i.e. the signal sources which the user wants to switch) are required to be screened out, and the signal sources on each screened interface are sequentially pulled out or closed, so that when the display device determines that the signal source connected with any one of the interfaces currently connected with the signal source is pulled out or closed, and determines that the pulled out or closed signal source is the currently displayed signal source, the interface with the highest current priority is screened out from the interfaces currently having input signals, and the signal source connected with the interface with the highest current priority is selected for display.
The second mode is as follows: if the other signal source (i.e. the signal source which the user wants to switch) is not connected to the interface of the display device, the other signal source (i.e. the signal source which the user wants to switch) only needs to be connected to the idle interface of the display device, so that when the display device determines that any idle interface is connected to a new signal source, after determining that any idle interface has an input signal, the current priority of any idle interface is further determined, and when the priority of the idle interface is higher than that of the interface connected with the currently displayed signal source, the new signal source connected with any idle interface is automatically selected for display.
Preferably, if the current priority of the idle interface is lower than the priority of the interface connected to the currently displayed signal source, the user may reset the current priority configuration information of the idle interface, so that the changed priority of the idle interface is higher than the priority of the interface connected to the currently displayed signal source, that is, when the user wants to switch another signal source for displaying, the user may also reset the current priority configuration information of the interface connected to the another signal source to switch the signal source, that is, the priority of the interface connected to the another signal source is reset to the highest priority to switch the signal source, so that when the display device monitors that the priority configuration information of any one interface changes, it determines that there is an input signal in any one interface, and then further determines the priority of the any one interface after changing, and when the priority is higher than the current priority of the interface connected with the currently displayed signal source, selecting the signal source connected with any one interface for display.
It should be noted that, in order to avoid the problem that the display device cannot normally display due to the absence of the input signal at the interface connected to the currently displayed signal source, when the display device determines that the input signal does not exist at any one of the interfaces currently connected to the signal source, the signal source connected to the interface is determined to be the currently displayed signal source, and then the interface with the highest current priority is screened out from the interfaces currently having the input signal, and the signal source connected to the interface with the highest current priority is selected to be displayed.
For example: continuing with the above example, if the user wants to select a game machine for display, the user only needs to turn off the set-top box 1, and at this time, when the display device a determines that the set-top box 1 is turned off, the game machine connected to the interface 2 (priority 2) with the highest priority at present is selected from the interfaces (interface 2 and interface 3) with the input signal present, and displayed.
If the user wants to select the set top box 2 for display, the set top box 2 may be connected to an idle interface (i.e., interface 4) of the display device a, and then the current priority configuration information (i.e., priority 0) of the interface 4 is changed to priority 4, so that when the display device a determines that the interface 4 is connected to the set top box 2, and determines that the interface 4 has an input signal, the current priority 4 (i.e., changed priority) of the interface 4 is further determined, and when the current priority 4 is higher than the priority 2 of the interface 2 connected to the game machine, the set top box 2 connected to the interface 4 is automatically selected for display.
If the display device a determines that there is no signal input to the interface 4 connected to the currently displayed set-top box 2, the display device a selects the game machine connected to the interface 2 (priority 2) with the highest priority from the interfaces (interface 2 and interface 3) with the currently displayed input signal to display.
The above embodiment is further described in detail by using a specific application scenario, and referring to fig. 2, a specific flow of a method for selecting a signal source of a display device in an embodiment of the present invention is as follows:
step 200: the user sets priority configuration information for each interface of the display device A in advance, and according to the degree of demand of the user on each signal source, the set top box 1 with the highest degree of demand is connected to the interface 1, the game machine is connected to the interface 2, the video disc player is connected to the interface 3, and the interface 4 is not connected with any signal source (namely, the interface 4 is an idle interface).
Step 201: after the display device A is started, the voltage values of the 4 interfaces are monitored in real time, the voltage value of the interface 1 is monitored to be within a preset voltage range, and it is determined that an input signal exists in the interface 1.
Step 202: the display device a continues to traverse each of its own interfaces, determining that there are also input signals for interface 2 and interface 3, in the method shown in step 201.
Step 203: the display device A determines the current priority configuration information of the interface 1 as follows according to the priority configuration information of each interface preset by a user: priority 3, the current priority configuration information of interface 2 is: priority 2, and current priority configuration information for interface 3 are: priority 1.
Step 204: the display device a determines that the current priority (priority 3) of the interface 1 is the highest, and selects the set top box 1 connected with the interface 1 to display.
Step 205: after the display device A determines that the set top box 1 is closed, the game machine connected with the interface 2 (priority 2) with the highest priority at present is directly selected from the interfaces (interface 2 and interface 3) with the input signals at present for display.
Step 206: after the display device A determines that the interface 4 is connected with the set top box 2, the current priority 4 of the interface 4 (namely the priority configuration information obtained after the priority configuration information of the interface 4 is changed into the priority 0 by a user into the priority 4) is further determined after the input signal is determined on the interface 4, and when the priority 2 of the interface 2 connected with the game machine is higher than the priority 2 of the interface 2, the set top box 2 connected with the interface 4 is automatically selected for display.
Step 207: after the display device A determines that no signal input exists in the interface 4 connected with the set top box 2 currently displayed, the game machine connected with the interface 2 (priority 2) with the highest current priority is selected from the interfaces (interface 2 and interface 3) with the currently displayed input signal for display.
