on the back of my dgtec 2000a and my sony 76 hd tv it has these connections?, what are these for?, does it improve picture?

they are black and white RCA connections, labeled HD, VD Sync.

thanks,
Vinh

Did you steal these units or do you have a manual? (Usually page 2 or 3)

i've lost the manual, i've had it for a while now...so i can't find it no more.

Fairs enough,

VD sync. is the most simple way to synchronize two camera by Vertical drive frequency to ensure video can be processed by plan old switcher or quad machine to display several image sources on the same monitor. VD signal usually constructed by a pulse on the repeat rate of 20/16.7ms ( 50/60 Hz) and with pulse width of 1~ 3 ms.

Bit gibberish, but it would seem they're some sort of ancillary connection that older machinery has to allow the video on one machine to be displayed on another. Probably not all that relevant to you, if you've got this far without it.

lol, o...k.....

thanks Peter!

The connections (as a whole) are known as RGBHV.

You have your regular component connections (Red, Green and Blue) and two sync connections (Black and White/Grey) that correspond to the Horizontal Sync and Vertical Sync signals.

It is meant to be higher quality connection than component, as it keeps the sync information separate, but I've yet to notice any difference.

The cables usually come in the BNC flavour, but sometimes you'll be able to find the straight up RCA type.

ah ok, i'll give it a go. the ones on the box and tv are just normal RCA's, not BNC
