Quantum Data 801GC, 801GF, 801GX manual American Hdtv ORed

The Scan setting determines if the video and sync timing is non-interlaced (progressive) or interlaced.

Most of the bottom half of the editor screen is taken up by the video and sync type settings. The first three lines determine the behavior of the sync selec- tion buttons. ACS kind determines what type of com- posite sync is added to the analog video outputs when the “ACS” button is pushed. The On setting, to the right, selects which of the component analog video outputs will have composite sync added. DCS kind determines what type of digital (TTL) com- posite sync is generated when the “DCS” button is pushed. DSS kind determines what type of digital (TTL) separate horizontal and vertical syncs are generated when the “DSS” button is pushed.

The choices for the ACS and DCS sync types are:

•none The operator can not make this selection. Nothing happens when the button is pressed.

•American HDTV ORed

•American ORed A simple Boolean OR combi- nation of the individual horizontal and verti- cal sync pulses.

•American w/serr Composite sync with serra- tion pulses during the vertical sync period.

•American w/serr & EQ Composite sync with serration pulses during the vertical sync pe- riod and equalization pulses added before and / or after the vertical sync period. The serra- tion and equalization pulses occur at twice the horizontal rate.

•European HDTV ORed

•European ORed A simple Boolean OR combi- nation of the individual horizontal and verti- cal sync pulses. The vertical sync delay and pulse are a half line shorter than shown.
