Electronic apparatus and display control method
View Patent ↗An electronic apparatus includes terminals, each being based on a specific standard and being used for communicating with an external device. The electronic apparatus includes a transmission module, an acquisition module and a display control module. The transmission module simultaneously transmits a power-on signal to external devices connected to the terminals, upon turn on of the electronic apparatus. The acquisition module acquires a physical address from one or more first external devices of the plurality of external devices by switching video input among one or more first terminals of terminals. The one or more first external devices are turned on and the one or more first terminals being connected to the one or more first external devices. The display control module displays device information of the one or more first external devices and terminal numbers of the one or more first terminals. Other embodiments are also disclosed.
1. An electronic apparatus comprising a plurality of terminals, each of the plurality of terminals being based on a specific standard and being used for communicating with an external device, comprising:
a transmission module configured to simultaneously transmit a power-on signal to a plurality of external devices connected to the plurality of terminals, upon turn on of the electronic apparatus;
an acquisition module configured to switch video input among one or more first terminals of the plurality of terminals, and to acquire one or more physical addresses from one or more first external devices of the plurality of external devices after the switching of the video input among the one or more first terminals is completed, the one or more first external devices being devices that are turned on, the one or more first terminals being terminals connected to the one or more first external devices; and
a display control module configured to display device information of the one or more first external devices and terminal numbers of the one or more first terminals, wherein the displayed terminal numbers are numbers corresponding to the acquired physical addresses.
2. The electronic apparatus of claim 1 , further comprising:
a determining module configured to determine power states of the plurality of external devices before the transmission of the power-on signal; and
a power-off module configured to transmit a power-off command to a second external device of the plurality of external devices, the second external device being a device turned on by the power-on signal.
3. The electronic apparatus of claim 1 , wherein the acquisition module is configured to transmit power state acquisition commands to the plurality of external devices after the transmission module transmits the power-on signal, and to determine power states of the plurality of external devices one by one, based on responses from the plurality of external devices.
4. A display control method for use in an electronic apparatus, the apparatus comprising a plurality of terminals, each of the plurality of terminals being based on a specific standard and being used for communicating with an external device, the method comprising:
transmitting a power-on signal to a plurality of external devices connected to the plurality of terminals, upon turn on of the electronic apparatus;
switching video input among one or more first terminals of the plurality of terminals;
acquiring one or more physical addresses from one or more first external devices of the plurality of external devices after the switching of the video input among the one or more first terminals is completed, the one or more first external devices being devices that are turned on, the one or more first terminals being terminals connected to the one or more first external devices; and
generating a video signal for displaying device information of the one or more first external devices and terminal numbers of the one or more first terminals,
wherein the displayed terminal numbers are numbers corresponding to the acquired physical addresses.
5. The display control method of claim 4 , further comprising:
determining power states of the plurality of external devices before the transmission of the power-on signal; and
transmitting a power-off command to a second external device of the plurality of external devices, the second external device being a device turned on by the power-on signal.
6. The display control method of claim 4 , wherein
the acquiring comprises transmitting power state acquisition commands to the plurality of external devices after the transmission of the power-on signal, and determining power states of the plurality of external devices one by one, based on responses from the plurality of external devices.
