A digital TV and a driving method thereof enable a user to view the digital TV without interruption even if the present operating system is in an abnormal state. The digital TV includes a digital TV receiving part for receiving and decoding a broadcasting stream from an outside, a host CPU (300) for controlling the digital TV receiving part, a local CPU (400) for controlling the digital TV receiving part if the host CPU operates in an abnormal state, and a programmable logic device (200) for switching the control of the digital TV receiving part from the host CPU to the local CPU if the host CPU operates in the abnormal state.
