Abstract
An AV device including a first signal transmitter configured to output a video signal and a first audio signal corresponding to the video signal to a display device; a first signal receiver configured to receive a feedback signal of the first audio signal from the display device; a second signal transmitter configured to output a second audio signal corresponding to the video signal; and a controller configured to determine a processing delay time of the display device by comparing the first audio signal and the feedback signal, and control the second signal transmitter to delay the output of the second audio signal based on the determined processing delay time.
Claims12
A display device comprising:
- at least one signal interface configured to connect with an audio/video (AV) device;
- a video signal processor;
- a display:
- a processor configured:
- to control the at least one signal interface to receive a video signal and a first audio signal from the AV device,
- to control the video signal processor to process the received video signal to display an image on the display based on the processed video signal, and
- to control the at least one signal interface to output a feedback signal of the first audio signal to the AV device, the feedback signal of the first audio signal being synchronized with the processed video signal, so that the AV device processes a second audio signal to be compensated for a processing delay time based on the feedback signal of the first audio signal.
A method of controlling a display device, the method comprising:
- receiving a video signal and a first audio signal from an audio/video (AV) device;
- processing the received video signal to display an image based on the processed video signal;
- outputting a feedback signal of the first audio signal to the AV device, the feedback signal of the first audio signal being synchronized with the processed video signal, so that the AV device processes a second audio signal to be compensated for a processing delay time based on the feedback signal of the first audio signal.
