1. An imaging apparatus for conducting a video call and providing broadcasting simultaneously, the imaging apparatus comprising:
- a broadcasting signal receiver which receives a broadcasting signal which includes a first image signal and a first acoustic signal;
a transceiver which transceives a second image signal and a first speech signal via a network;
an acoustic output unit which outputs the received first acoustic signal and the transceived first speech signal;
a user input unit which receives a second acoustic signal which includes a second speech signal which is generated by a user; and
a background sound canceller which comprises a first acoustic echo canceller and a second acoustic echo canceller, the first acoustic echo canceller being configured to generate a first output signal by cancelling the received first acoustic signal from the received second acoustic signal, and the second acoustic echo canceller being configured to generate a second output signal by cancelling the transceived first speech signal from the first output signal.

Abstract
Disclosed herein are an imaging apparatus and a control method thereof. The apparatus enables a user to simultaneously conduct a video call while watching a broadcasting program. When transmitting an acoustic signal to an opposite user, the apparatus cancels the speech of the opposite user and the background sound from the broadcasting program, and thus, superior communication quality may be maintained.

7. An imaging apparatus for conducting a video call and providing broadcasting simultaneously, the image apparatus comprising:
-
a broadcasting signal receiver which receives a broadcasting signal which includes a first image signal and a first acoustic signal; a transceiver which transceives a second image signal and a first speech signal via a network; an acoustic output unit which outputs the received first acoustic signal and the transceived first speech signal in an acoustic form; a user input unit which receives a second acoustic signal, which includes a second speech signal which is generated by a user, and an image signal relating to the user; and a background sound canceller which comprises a multi-channel acoustic echo canceller which is configured to cancel, on a first channel, the received first acoustic signal, and to cancel, on a second channel, the transceived first speech signal from the received second acoustic signal. - View Dependent Claims (8, 9, 10)

11. A method for controlling an imaging apparatus which conducts a video call between a first user and a second user, and provides broadcasting simultaneously, the method comprising:
-
receiving a broadcasting signal which includes a first image signal and a first acoustic signal; receiving a second image signal and a first speech signal from the second user; outputting the received first acoustic signal and the received first speech signal; receiving a second acoustic signal which includes speech generated by the first user; using a first acoustic echo canceller to generate a first output signal by cancelling the received first acoustic signal from the received second acoustic signal; and using a second acoustic echo canceller to generate a second output signal by cancelling the received first speech signal from the generated first output signal. - View Dependent Claims (12, 13, 14)

15. A method for controlling an imaging apparatus which conducts a video call between a first user and a second user, and provides broadcasting simultaneously, the method comprising:
-
receiving a broadcasting signal which includes a first image signal and a first acoustic signal via a broadcasting signal receiver; receiving a second image signal and a first speech signal from the second user via a transceiver; outputting the received first acoustic signal and the received first speech signal in an acoustic form via an acoustic sound output unit; receiving a second acoustic signal which includes speech generated by the first user via a user input unit; and using a multi-channel acoustic echo canceller to cancel on a first channel, the received first acoustic signal and to cancel, on a second channel, the received first speech signal from the received second acoustic signal. - View Dependent Claims (16, 17)
