Electronic Apparatus and Display Control Method

Abstract

According to one embodiment, an electronic apparatus includes a communication module which conducts communications with a plurality of external apparatuses, a storage module which stores an address list correlating a logical address and a physical address of each of the external apparatuses, a determination module which transmits a power-on signal to the external apparatus and thereafter determines a power state of the external apparatus, and an acquisition module which performs switching of input by the communication module after the determination module determines that the external apparatus has been powered on, and acquires apparatus information including the physical address of the external apparatus.

1 . An electronic apparatus comprising:
 a communication module which conducts communications with a plurality of external apparatuses;   a storage module which stores an address list correlating a logical address and a physical address of each of the external apparatuses;   a determination module which transmits a power-on signal to the external apparatus and thereafter determines a power state of the external apparatus; and   an acquisition module which performs switching of input by the communication module after the determination module determines that the external apparatus has been powered on, and acquires apparatus information including the physical address of the external apparatus.   
   
   
       2 . The electronic apparatus of  claim 1 , wherein when the switching of input by the communication module is performed with respect to the external apparatus which has been determined to be powered on by the determination module, after the switching of input is performed, next switching of input is performed after a predetermined standby time. 
   
   
       3 . The electronic apparatus of  claim 1 , wherein when the switching of input by the communication module is performed with respect to the external apparatuses, after the switching of inputs of the external apparatuses is all completed, the acquisition module acquires from the external apparatuses that have been switched the apparatus information including the physical addresses of the external apparatuses. 
   
   
       4 . The electronic apparatus of  claim 1 , wherein when the switching of input by the communication module is performed with respect to the external apparatus, the communication module allows a video input signal from the external apparatus to be input therethrough to the electronic apparatus. 
   
   
       5 . The electronic apparatus of  claim 1 , wherein when the power-on signal is transmitted to the external apparatuses, the power-on signal is transmitted simultaneously to each of the external apparatuses. 
   
   
       6 . A display control method for use in an electronic apparatus comprising: a communication module which conducts communications with a plurality of external apparatuses; and a storage module which stores an address list correlating a logical address and a physical address of each of the external apparatuses, the method comprising:
 transmitting a power-on signal to the external apparatus and thereafter determining a power state of the external apparatus;   performs switching of input by the communication module after determining that the external apparatus has been powered on; and   acquiring apparatus information including the physical address of the external apparatus.
