HDMI IMAGE QUALITY ANALYSIS

摘要

Systems and methods for evaluating video quality of HDMI data are provided. In one example an HDMI video quality evaluator controls a video device to render a test pattern and encode the pattern into HDMI. The video device is controlled to transmit the HDMI formatted pattern from an output port to an input port on the device, capture a frame of the pattern, and transmit the frame to the quality evaluator. The quality evaluator compares rendered pixels in the frame to test pixels in the test pattern to identify video quality errors. Errors that exceed a threshold are identified, and a test result is outputted that includes errors exceeding the threshold.

1. At an HDMI video quality evaluator, a method for evaluating video quality of data transmitted by a video device via HDMI, comprising steps of:
(a) controlling the video device to:
render a test pattern;encode the rendered test pattern into an HDMI format;transmit the HDMI formatted test pattern from an output port to an input port on the video device;capture a frame of the test pattern; andtransmit the frame to the HDMI video quality evaluator; (b) receiving the frame from the video device; (c) comparing rendered pixels in the frame to test pixels in the test pattern to identify one or more video quality errors in the frame; (d) evaluating the one or more video quality errors to identify any errors that exceed a threshold; and (e) outputting a test result that includes one or more of the video quality errors that exceed the threshold.
