Abstract: Disclosed herein are a signal receiving apparatus capable of improving signal compensation performance and a signal processing method thereof. The signal receiving apparatus includes a terminal configured to receive a signal from an external device; and an equalizer configured to reduce inter-symbol interference of the signal received through the terminal. A swing level of an output signal output from the equalizer is maintained in a preset range.

Abstract: The present disclosure provides a method of controlling a high-definition multimedia interface (HDMI). The method includes: reading, by a source device, extended display identification data (EDID) of a sink device when the sink device and the source device are connected; writing information about the source device in a status and control data channel (SCDC) structure; and reading, by the source device, the EDID again based on a predetermined field value included in the SCDC structure.

Abstract: A display device according to an embodiment of the present disclosure includes a display panel, a backlight unit configured to provide light to the display panel, an external input interface configured to receive an image frame from an external frame, and a processor configured to determine a scan rate of the image frame received through the external input interface, determine whether the determined scan rate is equal to a scan rate of a previous image frame, and control a dimming value of the backlight unit based on the determined scan rate of the image frame, when the determined scan rate is different from the scan rate of the previous image frame.
