Troubleshooting 3D Video
By Tom SchulteA look at how to troubleshoot complex HDMI systems when 3D video isn't displayed properly.
I'm sure you've noticed that video system troubleshooting has become much more challenging with feature-laden HDMI systems than it ever was with analog video systems, like good ol' trusty component video.
When an HDMI source device doesn't produce the desired output on an HDMI display, you most likely struggle to sort through all the possibilities for failure.
One reason is that the HDMI cable payload is much more complex, as it is probably carrying video signals and multichannel audio signals, as well as auxiliary channel EDID data, HDCP content protection handshaking, audio and video infoframe data, CEC data, and hot plug signaling data. It may be routed through cable extenders, splitters, AV receiver, and a video processor.
This can certainly add up to a challenging signal transmission system to maintain and troubleshoot.3D HDMI Content
To make HDMI video system installation and maintenance even more challenging for you, the HDMI cable may now also be carrying 3D video and 3D EDID Vendor Specific Infoframe data. The 3D Infoframe data in the source signal informs the display device that the video signal is 3D and the type of 3D format. The chosen 3D format will vary, depending on the signal source.Click here to continue.
