HDMI source/sink interoperable configuration determination process

摘要

A method and system that configures an HDMI source device to use initial output parameters for communicating with an HDMI sink device, detects an abnormal operation performed by the HDMI sink device, selects a test of the HDMI sink device, applies the test, evaluates a result to determine whether the test produces a desired result, and modifies the initial output parameters to create revised output parameters. When the test produces the desired result, the revised output parameters will enable the HDMI sink device to produce the desired result. When the test fails to produce the desired result, the revised output parameters are conservative parameters that fail to produce the abnormal operation. The method reconfigures the HDMI source device to use the revised output parameters for communicating with the HDMI sink device, and saves the revised output parameters.

1. A method, comprising:
configuring a High Definition Multimedia Interface (HDMI) source device to use initial output parameters for communicating with an HDMI sink device; in the HDMI source device, detecting an abnormal operation performed by the HDMI sink device; in the HDMI source device, selecting a test of the HDMI sink device, wherein the test is of a function that the HDMI sink device performs and that relates to correction of the abnormal operation; in the HDMI source device, applying the test when communicating with the HDMI sink device; in the HDMI source device, evaluating a result of the test to determine whether the test produces a desired result; in the HDMI source device, modifying the initial output parameters to create revised output parameters, wherein when the test produces the desired result, the revised output parameters will enable the HDMI sink device to produce the desired result, and wherein when the test fails to produce the desired result, the revised output parameters are conservative parameters that fail to produce the abnormal operation; in the HDMI source device, reconfiguring the HDMI source device to use the revised output parameters for communicating with the HDMI sink device; and in the HDMI source device, saving the revised output parameters, wherein the saving of the revised output parameters further comprises storing the revised output parameters in an HDMI configuration database, thereby allowing configuration of another HDMI source device to use the revised output parameters for communicating with the HDMI sink device.
