Video stopped working

I have audio but no video. It was fine yesterday and nothing has changed. The message says, "HDMI connection not permitted. Press select for more info. "



When I press select, the following appears. "The copyright holder of this video does not allow it to be viewed on an unsecured device connected with an HDMI cable...."



I tried rebooting, no help. I have no video either with recordings or other options like Netflix.



Thanks for any advice.
