Abstract

The invention provides a High Definition Multimedia Interface (HDMI) resolution setting method suitable for the video technique field comprising a. an HDMI output device reads Extended Display Identification Data (EDID) of an HDMI receiving device, and analyzing the resolution supported by the HDMI receiving device according to the read EDID; b. the HDMI output device arranges the resolution as the resolution supported by the HDMI receiving device. The technical scheme of the invention enables the resolution arrangement of the HDMI device intelligent and shortcut, the user only needs to correctly connect the HDMI line and the HDMI device can be normally use. The HDMI implements plug and play. The invention saves the problem of the HDMI resolution arrangement by the user, and brings out huge convenience for the user.

Description

technical field [0001] The invention belongs to the field of video technology, and in particular relates to a method for setting HDMI resolution. Background technique [0002] In recent years, HDMI (High Definition Multimedia, high-definition multimedia interface) technology has been more and more widely used in consumer electronic products, and more and more products with HDMI functions have entered the homes of users. The realization of HDMI requires the support of two devices, one is HDMI output device (HDMI SOURCE), such as DVD-Player (DVD player), STB (set-top box), BD (Blu-ray DVD), etc., and HDMI receiving device (HDMI SINK) , such as TV or Repeater (converter). [0003] HDMI is a standard dedicated to digital video / audio transmission developed by the HDMI organization. The HDMI interface can transmit uncompressed audio signals and high-resolution video signals in one transmission cable. After the HDMI SOURCE and HDMI SINK are connected through the HDMI cable, the ...
