Number electronic equipment, in the embodiment of the present application, will with described first electronic equipment for multiplex roles export machine top
As a example by box, described second electronic equipment are television set, the technical scheme in the embodiment of the present application is carried out in detail
Thin description.
When method in using the embodiment of the present application carries out signal source switching, step S101 is first carried out, it may be assumed that
Determining that the connected mode with the second electronic equipment is the first connected mode, wherein, described connected mode is at least wrapped
Include described first connected mode, described second electronic equipment for for output by described first connected mode from
The signal that described first electronic equipment obtains.
In the embodiment of the present application, refer to Fig. 2, the specific implementation of step S101 is as follows:
S201: detect at least one state of at least one signal output interface on described first electronic equipment
Parameter, wherein, described state parameter includes voltage parameter or the resistance of described output interface of described output interface
Anti-parameter；
S202: based at least one state parameter described, determines and the connected mode of described second electronic equipment
It it is the first connected mode.
In specific implementation process, continue to use above-mentioned example, after multiplex roles output set top box is in open state,
The CPU of Set Top Box will detect the state of each signal output interface automatically.With multiplex roles output set top box
As a example by there are HDMI, analog audio-video interface and three output interfaces of component interface, set-top box CPU
Can detect the magnitude of voltage of these three output interface or the resistance value of interface pin in real time, e.g., it is right to set
The HPD pin of HDMI carries out voltage monitoring, enters analog audio-video interface and component interface respectively
Line pipe foot resistance value is monitored, when, after set-top-box opening, the relevant parameter of the corresponding interface will be examined by CPU
Survey.It is of course also possible to be to detect according to default order, e.g., first CPU can monitor HDMI
The magnitude of voltage of interface, when judging what television set was attached not by HDMI by magnitude of voltage,
Then the pin impedance to analog audio-video interface detects, if judging, television set is not to pass through analog audio
Video interface is attached, then finally detect the resistance value of component interface.
In the embodiment of the present application, refer to Fig. 3, the specific implementation of step S202 is as follows:

The memorizer of top box is previously stored with preset voltage value and predetermined resistance value, if preset voltage value is 0V,
Predetermined resistance value is 0 Ω, when set-top box CPU calculates current by preset voltage value and predetermined resistance value
The voltage difference carving HPD pin is 2.3V, and the impedance differences of analog audio-video interface is 5 Ω, and component connects
Mouthful impedance differences be 3 Ω, meanwhile, in the memorizer of Set Top Box, also storage has corresponding with magnitude of voltage pre-
If threshold value, such as 2V, and the predetermined threshold value corresponding with resistance value, such as 10 Ω, now, due to 2.3V > 2V,
5 Ω < 10 Ω, 3 Ω < 10 Ω, it is judged that the only magnitude of voltage of HPD pin meets pre-conditioned, now,
The CPU of Set Top Box determines that the connected mode with television set is HDMI connected mode.
If set-top box CPU is detected by the order preset, first CPU obtains HPD pin voltage value,
Such as 0.3V, it is 0.3V by calculating voltage difference with the preset voltage value that prestores in set-top box memory,
Less than predetermined threshold value 2V, thus judge that the connected mode of television set is not HDMI connected mode,
Then CPU obtains the resistance value of analog audio-video interface, such as 15 Ω, by prestoring in set-top box memory
Predetermined resistance value to calculate resistance difference be 15 Ω, more than predetermined threshold value 10 Ω, thus judge TV
The connected mode of machine is analog audio-video interface connected mode.
If set-top box CPU judges it is not any one in above-mentioned three kinds of connected modes, now, machine
Top box CPU can export cue, check after prompting user's power-off connecting line whether connect good or

In specific implementation process, continue to use above-mentioned example, when set-top box CPU judges the feedback of television set
After audio signal is different from inspection signal, set-top box CPU then generates for controlling television set switching signal source
Control signal.The code value of meeting typing television set switching signal source signal in advance in the memorizer of Set Top Box, should
The input method of code value: first this code value of TV remote controller is learnt in set-top box remote controller, Set Top Box
CPU just can pass through set-top box remote controller, and this code value is entered into internal memory.Now, set-top box CPU then obtains
Code value corresponding with controlling television set switching signal source signal in access to memory, generates the control including this code value
Signal processed, and send to television set, thus control television set switching signal source, refer to Fig. 6, for this Shen

After number, set-top box CPU will send, again by HDMI connecting line, the inspection signal that signal frequency is 50Hz,
And obtain, again by pick up, the feedback audio signal that TV loudspeaker sends, it is judged that feedback audio signal
Frequency the most identical with 50Hz, if identical, it is determined that the signal source pattern going out television set is HDMI mould
Formula, thus judge that the setting up procedure of television signal source completes.If the frequency of feedback audio signal and 50Hz
Still different, then set-top box CPU will send the control signal controlling television set switching signal source again, until
The frequency of the feedback audio signal that television set sends is identical with 50Hz.
