Abstract:
1. A digital display apparatus comprising: a signal intensity detect unit to divide a digital input signal into a strong signal and a weak signal based on a predetermined level; a tuner unit to amplify the weak signal, bypass the strong signal, demodulate each of the weak signal and the strong signal, and output the demodulated signals as a digital stream; a control unit to receive the digital stream and determine whether an error has been generated in the digital stream, and if the error has been generated, output a conversion signal to reverse a working state of the tuner unit; and a digital signal process unit to receive the digital stream from the control unit and convert the received digital stream to a signal type that can be outputted if the error has not been generated, wherein, upon receiving the conversion signal from the control unit, the tuner unit reverses an amplification state and a bypass state.
