Well, this at least answers my question about video source(s).
For context, the problem encountered on the interception was the video that was made available to the replay booth.
Sites a couple of rules on point:
"Whatever video [replay officials] use must be available in the booth."
Is that really true? I know that Rogers Redding didn't write the rule in the NCAA Rules and Interpretations manual; the NCAA rules committee did.
Here's what it says under Rule 12, Section 4, Article 3a:
All equipment used reviewing a play during the replay process[SIZE=16.3636360168457px] [/SIZE]
and the personnel using that equipment shall be located in a separate, secure[SIZE=16.3636360168457px] [/SIZE]
location in the press box. This room shall not be available or accessible to any[SIZE=16.3636360168457px] [/SIZE]
person not directly involved in instant replay.
So, if the equipment isn't working, can't the replay official call someone and say, "Hey, get me a monitor that works"? The rule does not say that the replay official can't leave the room. It does not say he can't ask that a working monitor be brought to him. It does not say he can't ask that the game be delayed a few minutes until a glitch in his monitor's feed is fixed. It does not say he can't leave the booth and seek out a working monitor.
In fact, subsequent NCAA rules indicate just the opposite:
Rule 12, Section 6, Article 1c:
All reviews shall be based upon video evidence provided by and coming directly from the televised production of the game or from other video means available to the replay official.
Rule 12, Section 6, Article 2a:
There is no restriction on the number of times the replay official may stop a game for reviews.
Rule 12, Section 6, Article 2b:
The replay official is under no time limit for a review.
