Reference Signal	Requirements
Bi-level sync	Signal meets SMTPE 170M timing requirements.
Tri-level sync	Signal meets SMPTE 274M timing requirements for analog sync for
	1080i standards, and SMPTE 296M timing requirements for analog
	sync for 720p standards.
Black burst	Signal meets SMTPE 170M timing requirements.
Note	If External is selected, ensure that the proper signal is
