Audiovisual (AV) Device and Control Method Thereof

Abstract

According to one embodiment, video image and audio signals are transmitted to a plurality of electronic devices each having at least one of a video image display function and an audio reproducing function. Information indicating the fact that at least one of a video image and audio has been set in a mute state is acquired from each of the electronic devices. Based on the information, a processing operation is applied to the video image and audio signals supplied to each of the electronic devices.

What is claimed is: 
     
         1 . An AV device comprising:
 a processing section configured to apply a predetermined signal processing operation to a digital voice signal;   a storage section configured to store information indicating time required for the signal processing operation at the processing section, and when a voice has been set in a mute state, store the information indicating the time required for the signal processing operation by the processing section which is rewritten into a value that cannot be taken in general; and   a control section configured to output information stored in the storage section.   
     
     
         2 . The AV device of  claim 1 , wherein when the voice has been set in a mute state, the storage section is configured to store the information indicating the time required for the signal processing operation by the processing section which is rewritten into a value indicating that the time is set to “0”. 
     
     
         3 . The AV device of  claim 1 , wherein the storage section is an EDID memory.
