DISPLAY APPARATUS AND CONTROL METHOD THEREOF

摘要

A display apparatus comprises an interface to receive a signal from an external source, and operates either in a digital packet video link (DPVL) mode or in a raster video mode. The display apparatus decodes data of the signal input through the interface, determines whether the signal is a DPVL signal on the basis of the decoded data, and operates in the DPVL mode when the signal is determined as the DPVL signal or in the raster video mode when the signal is not determined as the DPVL signal. A display apparatus and a control method thereof determine whether input data is the DPVL signal on the basis of decoded results of the input data, thereby displaying a picture normally even based on an abnormal DPVL signal.
