3.4.2 Video Pixel Encoding RGB – Test ID 7-23 Example
The following sequence of commands are used to run the 7-23 test.
Initialization
p-scope> hdmitx disable // disables the 980 HDMI Protocol Analyzer Tx port.
p-scope> slink down // disables the Encrypted Link Analyzer mode.
p-scope> mon hdmi // configuring the 980 for HDMI (rather than DVI).
p-scope> hp // toggle hot plug to cause an EDID read by the source.
Asserting 1sec HP pulse
Note: The Automated Test System now has to put the source device into the proper video and audio mode (i.e.
resolution, colorimetry, audio format etc.). If you are certain that the source is in the proper mode executing the
following command (vinfo) is optional. Otherwise the Automated Test System would have to parse out the
command response and issue a notification to the operator.
p-scope> vinfo // verify incoming video parameters.
