In NCAA basketball, there are media timeouts at the first whistle after the 16:00, 12:00, 8:00 and 4:00 minute marks of each half.

What happens if there is no whistle from the four minute mark until the half-time or final buzzer? It almost happened in this game here:

What would have happened if there was no whistle at 0:08?
