摘要:
A broadcast receiving terminal is equipped with a receiving unit for receiving a broadcast signal; a separating unit for separating audio coded data and band expansion information from the broadcast signal received by the receiving unit; a low frequency band audio decoding unit for decoding the audio coded data so as to output low frequency band audio data; a high frequency band audio producing unit for producing high frequency band audio data by employing the band expansion information and the low frequency band audio data; a switching unit for switching a sound reproducing mode of the broadcast receiving terminal between a first mode for reproducing sound based upon both the low frequency band audio data and the high frequency band audio data, and a second mode for reproducing sound based upon only the low frequency band audio data; and a control unit for controlling the switching unit so as to constitute a mode selected in response to a predetermined condition.
