RGB/CGA/EGA/YUV to VGA HD VIDEO CONVERTER BOARD to S-Video

[s34n]

Hi,

Does anybody know if this board will output to S-Video (I have an NTSC CRT TV with S-Video input in rear) without additional re-encoding.

I already have this board (RGB/CGA/EGA/YUV to VGA HD VIDEO CONVERTER BOARD)

Manual: http://www.digitalsystemsdesign.co.uk/product_uploads/13063268261.pdf
Output signal: VGA 640*480,800*600,1024*768,1360*768

I wondered if using something like the cable pictured below... plugged into the VGA output of the board in the video into the TV would work

Thanks in advance

no.

those cables only work for the items they were designed for. the videocard or whatever it was designed for detects you've plugged the dongle in and outputs the appropriate signal. it doesn't work with anything else.

you need something more like this:

you can pick them up on ebay for 20 bucks.

Thanks for the reply.

Would you suggest that this combination of those two 'cards' is the easiest or cheapest to convert from arcade 15KHZ to NTSC S-Video? I already had the first card, but without already having the RGB/CGA/EGA/YUV to VGA HD VIDEO CONVERTER BOARD, would it still be the best way?

Thanks

since you already have a board that converts from 15k to VGA, use the converter i linked before to convert the VGA to svideo.

it's not going to be great, but it will work. (scaling a signal more than once is not great.) this is the cheap way.

otherwise you are looking at a downscaler that has a rather custom input and output capability and those have been known to go for upwards of 600 bucks.

what game do you have and what are you trying to accomplish?

Thanks for the reply.

It's a Dance Dance Revolution. Output is 15khz and has a VGA type connector (Not VGA signal though

I have two of these machines, so I was looking for a good combination of best vs cheapest for the second machine
Is there something in-between those two options? (Converting from this to S-Video). Maybe with a single scaling?

Side note:I don't want to use an LCD/Plasma screen, the lag makes the game hard to play. So I was thinking an NTSC CRT TV with S-Video input would be the best? (Ruling out an arcade monitor too due to cost)

futzing around with an image with a scaler and whatnot is probably going to introduce just as much lag as it would just running straight LCD anyways.

the scalers have to wait for a whole frame to be input to the buffer so it can do maths on it. then it does the math and then outputs the frame to another buffer that puts it on your output screen of your choosing. it's not much, but it can add up especially when running into another conversion process.

I honestly would look for another TV. there are lots of CRT's out there that have YPbPr "component" input. and the quality will be many many times greater than upscaling, then downscaling the image.
