Disclosed are a digital display apparatus and method. The digital display apparatus includes a signal intensity detect unit, a tuner unit, a control unit, and a digital signal process unit. The signal intensity detect unit divides a digital input signal received through an antenna into a strong signal and a weak signal based on a predetermined level. The tuner unit amplifies the weak signal, bypasses the strong signal, demodulates each signal and outputs a digital stream. The control unit receives the digital stream and determines whether an error is generated, and if the error is generated, outputs a conversion signal to reverse a working state of the tuner unit. The digital signal process unit receives the digital stream and converts it to a signal type that can be outputted if the error is not generated. Accordingly, breaking or freezing of a video on the digital display apparatus can be compensated.
