Patent ID: 8923620

Claim:
A broadcast receiving apparatus for providing a multilateral video communication, comprising: a position determining unit determining a position of a user by analyzing a voice signal received through a microphone array; a detection unit detecting and identifying a face of the user in the determined position from an image received through a camera; and a transmission unit transmitting the identified face of the user and the received voice signal to a terminal through a network, wherein the camera captures the image of a plurality of users, wherein the detection unit identifies the face of the user among the plurality of users, wherein the transmission unit transmits only the identified face of the user or the upper half of the body of the user from among the plurality of users, and wherein a voice signal coming from the determined position is amplified and voice signals coming from in other directions around the determined position are removed, and wherein the detection unit detects the motion of the user when the face of the user is not detected, detects the face of the user when the motion of the user is not detected and determines whether a number of failures within a predetermined time exceeds a threshold value when the detecting the face of the user has failed, and when the number of failures exceeds the threshold value, stops the detecting the face of the user, and performs the detecting the motion of the user.
