One of the latest was HDCP v2.
4K on HDMI requires HDCP. And it also requires HDCP all the way from he source to the display. Which means if your streaming box is HDCP v2 and so is your receiver, your TV needs to support it (and thus be 4K capable) as well. The idiots who designed this didn't think of where the TV is _not_ 4K capable, in which case the receiver says "I can't display this content".
I had to do a hack to make my streaming box drop to HDCP 1.4 (until they did a software release so I could do it in the box itself) and thus come back down to 1080p for it to all work. All because in the standard the receiver couldn't or wouldn't automatically tell the streaming box to downgrade.
