<p>Provided are a broadcast switching device and method and a terminal, which are used for terminal broadcast mode switching. The broadcast switching device comprises: a second signal playing unit; a first signal playing unit; a signal receiving module, which is connected to the first signal playing unit and the second signal playing unit respectively, and configured to receive a first signal and a second signal and preferentially to receive the first signal; a parsing module configured to parse the first signal to acquire the signal intensity of the first signal; a decision module configured to compare the signal intensity of the first signal with a preset playing intensity to obtain a comparison result; and a switching module configured to control the signal receiving module to receive the second signal when the comparison result is that the signal intensity of the first signal cannot satisfy the preset playing intensity. When the signal intensity of a digital broadcast signal cannot satisfy the playing requirements, the adoption of the technical solution of the present invention can switch to an FM frequency modulation broadcast signal, so as to provide a user with an optimal hearing experience.</p> |
