Or have private-key encoding. That’s the case for HDMI: No-one can manufacture devices that aren’t approved.
Of course the funny part is, it’s designed so pirates can only send HDMI output to approved screens (=not recording devices), but for backwards comparibility, they has to allow HDMI-to-SVGA adapter with decoding, so the breach is wide open. But you get the intent: HDMI was supposed to bea fully-encrypted standard with only preapproved devices.
- AlexCoventry 8y ago> HDMI was supposed to bea fully-encrypted standard with only preapproved devices. Interesting. Where can I read more about this intent, and how it was compromised?

- AlexCoventry 8y agoThanks. I found that before I asked the question. It doesn't indicate the intent of HDMI, or that HDCP compliance is mandated for HDMI devices.
- maltalex 8y agoThe encryption is a legal issue, not a technical one. Of course it can be circumvented like all forms if drm. The point is that by going around the drm, even if it’s by doing something trivial, you are committing a crime.
- toomuchgov 8y agoI thought that was HDCP?
