Abstract

The present invention provides a video display apparatus (100) at least comprising a display screen (10), at least one loudspeaker for emitting a sound in association with at least one still or moving image displayed on the display screen (10), at least two spatially separated microphones (1, 2, 3), and an audio signal processing unit (20) configured to separate the sound emitted by the loudspeaker from a sound received by the microphones. The present invention also provides a method of operating a video display apparatus, wherein the method at least comprises displaying on a display screen of the apparatus at least one still or moving image, emitting a sound from a loudspeaker of the apparatus in association with displaying the at least one still or moving image, receiving a sound by at least two spatially separated microphones of the apparatus, and separating the sound emitted from the loudspeaker from the sound received by the microphones. Such a method allows for three-dimensional localization and separation of sound sources to receive and execute voice commands for control of a video display apparatus, such as a television, without the need for a remote control.
