It's the HDCP that makes them run around in circles and pee on themselves.

The HDMI connector is only one means to transfer data and a copy protection scheme to go along with it. HD-SDI can carry the video that HDMI does, the 8 channels of 24/96 audio that HDMI does and, with little effort, a copy protection scheme (though none are used today). It's also a more robust method than HDMI for transferring signals: SDI protocols allow for 1000ft, while HDMI, over copper, is rather limited for 1080p60 (about 50ft for the very best cables) unless add-on signal boosters are used (not very cost efficient).
