Analog to sdi converter from DVD player

PostWed Jan 23, 2013 1:35 am

We have a Sony Mcs 8m switcher. I bought a couple
Analog to sdi converters so we can output
Component outs from DVD player to sdi input.

We are not seeing anything coming out of the converter to the
Sdi input of the switcher. I don't have a monitor with sdi to
See if it's the switcher. Wondering if hdcp has anything to do with this.
Any help would be appreciated.

HDCP isn't the issue, as that's only for a digital connection (ie. HDMI). My guess is to make sure all of the resolution settings are all the same. Is the player outputting 480i/p, upscaling to HD, etc.?

And are the DIP-switches at Anonlog-to-SDI-converter set correctly ?

I put the system settings to 480 and do see the
DVD player but it's doubling the same image side by side.

Not sure what the Dip switches are supposed to be set at.

Dip5 has to set to "off" for component input. The settings are printed on the bottom of the box....

You're close, I think: HDCP only applies to the HDMI output, but DVD players typically insert non-standard crud in the vertical interval of the analog outputs to prevent VCRs from locking to the video.

This is an occasional problem at my church: we will need to play a teaching disc for which we have bought rights to show, but our video system won't pass the video through to the projectors.

We have solved this by running the video through a processing amplifier that regenerates the sync and blanks out lines 10-20. We happen to use a Grass Valley 3240, which is an NTSC model; I believe that the 3241 is a PAL version. You can probably find one on eBay, or a local television station might have one sitting on the shelf now that analog video is largely a thing of the past for broadcasters.

A proc amp like this is actually designed for composite video, but you should be able to the Y (luminance) channel through it and accomplish the same result -- you would need to turn off the chroma. The delay on most proc amps is minimal, so the luminance and chrominance should still be pretty well matched up.
