Abstract

The invention discloses a data processing method and a data processing device, a converter, wherein the method includes steps of analyzing a first EDID data according to the EDID data specification, and acquiring multiple time sequences, wherein the first EDID data is downstream EDID data, and the first EDID data is temporarily stored in the EDID memory; acquiring the bandwidth for every time sequence in multiple time sequences; when the bandwidth for the first time sequence is more than the first preset bandwidth, performing the filtering process according to the data structure of the first time sequence, and acquiring the second EDID data, wherein the first time sequence is any one of multiple time sequences; storing the second EDID data in a local EDID memory, so that the HDMI reads the data. The invention solves the technical problem of oversized band width of the HDMI-DP converter in the prior art.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data processing method and device, and a converter. Background technique [0002] HDMI to DP converters are widely used in graphics cards and display adapters. Currently, graphics cards that support HDMI 1.4 can output resolutions up to 4K 30Hz. A prominent feature of HDMI Source is to select the best output video with the maximum resolution according to the content of the downstream EDID. Of course, the bandwidth required for the output video cannot exceed the maximum output bandwidth of the HDMI Source. As an HDMI to DP converter, the maximum output bandwidth is not static, but depends on the result of the current Link Training, and this result is restricted by the bandwidth capacity of the DP transmitter and receiver, link signal quality, and link length. [0003] For example, if the bandwidth capacity of the HDMI to DP converter is 5.4G 4Lanes, and the bandwidth capacity of...
