Sorry for the nitpick, but that isn't the analog hole. The analog hole occurs when your monitor displays the video. At that point, you can point a camera at it and record the video, albeit with a loss in quality. Removing the analog hole would require pushing the attestation and encryption one layer further, into your brain or eyes.

My perspective is the analog hole is all of the above: your eyes, the display, and the composite video connection (for an old standard definition TV)
