Abstract
An apparatus and method for automatically detecting a display mode to be used in a serial data interface (SDI) of a decoded video signal is provided. The apparatus for detecting a display mode includes a mode detector which detects a predetermined display mode by counting clock pulses generated between a present horizontal synchronous signal and a next horizontal synchronous signal from input decoded video signals, and a signal processing unit which converts formats of the decoded video signals so as to correspond to a display mode detected by the mode detector, serializes and outputs the decoded video signal. By deleting a control signal indicating a display mode, a control signal that does not coincide with processed data as a result of an incorrectly or incompatibly designed controller can be prevented.
