Summary: Almost ready
--------

Comment:
--------

I looked in vain for a shepherd's writeup or even a shepherd. I have no idea whether
this draft has gone through adequate expert review, and I am certainly not an expert.

Major Issues:
-------------

This is an informative document that states "Ad-ID is the industry standard..." but doesn't
provide a clear normative reference to an industry standard at that point. I assume that
would be [SMPTERP2092-1]. If so it should be referenced right there. Unfortunately it's
behind a pay wall (http://ieeexplore.ieee.org/document/7291518/). The IESG needs to confirm
whether that's acceptable.

>   An Ad-ID Identifier consists of a unique eleven character string
>   or a unique twelve character string (video codes only).

What's a "character"? ASCII or UTF-8?

The informative reference [Ad-ID-INTRO] doesn't seem to know whether it's a technical
appendix or a reference, and the URL that it cites is unhelpful. The material at
http://www.ad-id.org/how-it-works/ad-id-structure seems to be what is needed but
partly duplicates what is in the draft. Maybe this material is only given here because
the actual SMPTE standard costs more than $100? If so, I think it should be clearly
labelled as informational material and that only the SMPTE document is definitive.
