Abstract

A video apparatus and a method for recognizing a digital interface thereof are disclosed. The method for recognizing the digital interface of the video apparatus enables a multimedia source to re-execute a high definition multimedia interface (HDMI) recognition to deal with errors when the multimedia source connected using the HDMI fails to recognize that the video apparatus supports the HDMI due to a cable connection error, an EDID recognition error, or an HDCP authentication error. The video apparatus determines whether or not a format of an input video signal is HDMI or DVI, and displays a result on a screen so that a user can recognize the format. As a result, the video apparatus enables a user to recognize whether or not the HDCP authentication error is occurred, and notifies the user of a method for improving the cause of the HDCP authentication error.

Description

technical field [0001] Apparatuses and methods consistent with the present invention relate to digital interface identification, and more particularly, to a video device for correcting HDMI identification errors in a video device supporting High Definition Multimedia Interface (HDMI), and for identifying a video device method of digital interface. Background technique [0002] Recently digital video has become widespread, and there is a gap between multimedia sources providing digital video, such as set-top boxes, DVD players, and PCs, and video equipment, such as audio-visual (AV) Provides an interface between devices, monitors, and digital televisions (DTVs). [0003] The digital interface may be a digital visual interface (DVI) or a high-definition multimedia interface (HDMI), etc., and high-bandwidth digital content protection (HDCP) is standardized to prevent duplication of digital video provided through the digital interface. [0004] Typically, HDMI is used to conne...
