035-2020 – How to remove HDCP from HDMI signal

What is HDCP?

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection developed by Intel Corporation in 2000, to prevent copying of digital audio & video content as it travels across DP (DisplayPort ), DVI (Digital Visual Interface), HDMI (High-Definition Multimedia Interface) connections.

Some computers and tablets encrypt the video output by default as a general policy, even if the content to be displayed do not require HDCP encryption. The result is no video.

The workaround is to use the VGA Adapter, but if you want HD or higher resolution you might have to look into one of this splitters for home/light use. Around £15 on Amazon (Limitation may apply).

For professional use, I would recommend an Extron product.

Since I spent almost the entire day researching this topic I think the photo of today, part of “a photo a day challenge 2020” should be somewhat related.
