ABSTRACT:
A broadcast receiving system incorporating an echo canceling means automatically initiates recording of the broadcast and also controls the sound volume by taking into account the viewer's movements and ambient conditions, by using echo canceling means of the type used in hand-free telephones. The broadcast receiving system includes a broadcast receiving unit for receiving a broadcast in the form of either digital or analog signals; an echo canceling unit; and a determining unit for monitoring the amount of residual echoes in the echo canceling unit, determining whether the amount of residual echoes has exceeded a predetermined value, and instructing a storage unit to store the broadcast if the amount of residual echoes is found to have exceeded the predetermined value.
