RGBS to YPbPr converter?

post #1 of 11
Thread Starter 
I'm hoping you can help me with what I'm trying to do. I am trying to capture higher resolution video through an ultrasound machine through a Hauppauge HD-PVR.

The ultrasound machine has BNC connectors for RGB and a single synch connector.

So it seems I'm looking for a RGBS to YPbPr converter? I've looked and perhaps I'm confused but I haven't seen such an animal.

Thanks in advance

I found quite a few doing a seach on Bing, none are inexpensive here is one that costs about $120

Waldorf, the link you provided is for going from Component to a PC's DB15 connector.
I think the OP wants to go from 3 separate BNC RGB cables (and Sync) to 3 separate Component RCA jacks.
The company you linked doesn't seem to offer such a converter that I could find. The OP has more of a commercial device and I would think $120 would be a good price if such a device could be found, I haven't seen one but that doesn't mean it's not available.

OP might want to check Monoprice. Here's a copy/past from the Knowledge base tab on this product.
Question: My display has composite (ie: combined) sync with only 4 BNC inputs not 5. (Examples: Barco 7xx/Cine7 or Ampro). What cable do I order? How do I hook it up?
Answer: Order the GREEN (5-BNC breakout cable) and combine the H/V sync lines using a $2 BNC T-connector like this. You could also use an Extron 109 or 202 box as well to combine the two sync lines.


The confusion seems to be when someone searches for RGB they generally get the DB15 PC variety and not the three separate cables as used years ago or commercially. I searched for BNC at Monoprice and got the above device (which I'm not sure will do you any good). It seems to go from 3 separate RGB to the DB15 which you'd then have to convert to component.

Monoprice searching for BNC.

I think the link provided is correct by my interpretation. I am not sure that it supports both H and V sync on one line though.

Then at the very least the OP would need something this and a "$2" BNC Tee connector that I couldn't find at Monoprice but was mentioned in my quote above.

I would get a sync converter to get the signal from RGBS to RGBHV. This would make it much easier to get it to YPbPr. You can probably find an Extron SC 210 sync converter on Ebay for < $30.

I'm researching a similar problem. We have medical equipment that outputs RGBS on 4 BNC connections. We want to use consumer grade LCD panels to display the video however they typically only accept component or HDMI.

We are currently struggling with using a DVDO Edge scaler however, while it will work for one procedure, when we change the instrument out, the DVDO Edge will not re-recognize the signal (looks as if its out of sync) and shuts down. I'm still working with DVDO on a solution if one exists. The Edge costs about $600 at amazon.com

I've also considered trying the Kramer FC-14 converter (costs about $250). Can anyone weigh in with their opinions?

Please note that RGB/S is much different than VGA and RGB/HV, so these VGA to component converters and VGA breakout cables will not work. Thanks.

?

VGA signal (not connectors) is the exactly same as RGBHV, taking into account the different resolutions and scan rates, and the only difference between those signals and RGBS or RGsB is how the sync is processed, which can easily be split or combined.


This device will convert any type of RGsB/RGBS/RGBHV to component video (not resolutions and scan rates). http://www.hdtvsupply.com/rgb-to-com...converter.html

I've never tried this particular product, but it should work fine. The Kramer F-14 & F-16 should also work.

I needed a transcoder to do the opposite, go from YPbPr to RGBHV. I found a key digital kd-ctca2 for ~$30 shipped on Ebay. I think the KD-VTCA2 (might be other/newer models) will do what you're looking for, cheaply. Might be worth checking out.

Whether or not they work depends on the display device. Most Samsung computer LCD displays work fine when fed RGsB (sync-on-green) through their VGA connector, for example. Many of the cheaper LCD panels don't. Very few document this capability: you have to try it to find out if it works.

The current Key Digital unit is KD-VA5:
