Information Processing Apparatus and Output Control Method

Abstract

According to one embodiment, an information processing apparatus includes a display, a speaker, a connector to output a video signal and audio signal, a display driving module to control outputting of the video signal with respect to the display and connector, a sound driving module to control outputting of the audio signal with respect to the speaker and connector, and an output control module to Instruct the sound driving module to output the audio signal from the connector when an event of instructing the display driving module to output a video signal to the connector occurs.

1 . An information processing apparatus, comprising:
 a display;   a speaker;   a connector to output a video signal and audio signal;   a display driving module configured to control outputting of the video signal with respect to the display and connector;   a sound driving module configured to control outputting of the audio signal with respect to the speaker and connector; and   an output control module configured to instruct the sound driving module to output the audio signal from the connector when an event of instructing the display driving module to output a video signal to the connector occurs.   
   
   
       2 . The information processing apparatus of  claim 1 , wherein the output control module instructs the sound driving module to output an audio signal only to the connector when a video signal is output only to the connector in response to an instruction with respect to the display driving module. 
   
   
       3 . The information processing apparatus of  claim 1 , wherein the connector is detachably connected to a high-definition-multimedia interface (HDMI) cable. 
   
   
       4 . The information processing apparatus of  claim 1 , wherein the output control module instructs the sound driving module to switch an output destination of an audio signal from the connector to the speaker when an event of an instruction with respect to the display driving module to switch a display destination of a video signal from the connector to the display occurs. 
   
   
       5 . The information processing apparatus of  claim 1 , further comprising a detecting module configured to detect that a cable is disconnected from the connector,
 wherein the output control module instructs the sound driving module to switch an output destination of an audio signal from the connector to the speaker when the detecting module detects that the cable is disconnected from the connector in a state in which the audio signal is output only from the connector.   
   
   
       6 . The information processing apparatus of  claim 1 , further comprising a resume module configured to restore a state set up at previous power-off time when a power source is turned on,
 wherein the output control module instructs the sound driving module to switch an output destination of an audio signal from the connector to the speaker when a video signal is set in a state other than a state in which the video signal is output only from the connector in a case where a state in which the audio signal is output only from the connector is restored by the resume module at the power-ON time.   
   
   
       7 . The information processing apparatus of  claim 1 , wherein the output control module instructs the sound driving module to output an audio signal from the connector when a screen of a video signal output from the connector is set to primary in a case where the video signal is output from the connector for multi-display in which the same display screen is divided and displayed on a plurality of display devices. 
   
   
       8 . The information processing apparatus of  claim 1 , further comprising a setting module configured to set an output destination of an audio signal when clone display for simultaneously the same display screen together with another device connected via the connector,
 wherein the output control module instructs the sound driving module to output an audio signal from the connector when an output destination of the audio signal is set to the other device by the setting module in a case where a video signal from the connector is output for the clone display.   
   
   
       9 . An output control method of an information processing apparatus including a display, a speaker, a connector which outputs an video signal and audio signal, a display driving module configured to control outputting of a video signal with respect to the display and connector, and a sound driving module configured to control outputting of an audio signal with respect to the speaker and connector, the method comprising;
 instructing the sound driving module to switch an output destination of an audio signal from the speaker to the connector when an event of an instruction with respect to the display driving module to switch a display destination of a video signal from the display to the connector occurs.
