generate a 10 bits monochrome video signal with 5421 board and VIDEO library

[sebastien.durand]

Hello all,

I use a 5421 for some video generation application.

Today, I'd like to generate a 10 bits resolution video signal in monochrome mode (for CCIR as well as RS 170 video format).

So, I tried to modify the example VI which is called : niVgen_Basic_Create_Composite_Signal_from_BMP_Image.vi. The input file is a 10 bits tiff format image and I defined the image that is used for generation as a 16bit image. The trouble is it doesn't seem to work. So my question will simply be : is it possible to generate a 10 bit depth monochrome image with 5421 board and the library i have. If so, what do I do wrong?

Thanks for help,

Regards,

Sebastien DURAND

PS : I attach the vi as i tried to modify it.

Hi Sebastien !

You said you defined a 10 bits tiff image as a 16 bit image. Then don't you think the conversion occuring is a potential problem ? Did you try to convert neatly this picture and run the VI ?

Hi Matthieu,

Thanks for answering,

What do you mean by "convert neatly this picture"?

The fact is I tried to open the image i have generated, and it seems to work well when opened with 16 bits depth resolution ... but I am not sure at all the generation part of the VI is able to handle a 10 bits depth monochrome signal ... (video library???)

I join an exemple of a 10 bits resolution image and the VI that is able to open the image (which is exactly the same as what is done in the previous VI I sent), That means that for me the image is properly interpreted by LabVIEW ...

Hi Sebastien,

Sorry I can't help, but what is this 'Video Library'?  Is this from the VideoMASTER software tools, or something else?  I'm looking to generate composite video using a 5421 but not sure what tools exist to do this....any idea?

Thanks,

Todd

Thanks, I downloaded it an will test it out with a loaner PCI-5421 next week.

Do you know if it works with a PCI-5421?  NI's site doesn't offer the video generation version of VideoMASTER with a PCI-5421, only with a PXI-5421.

Hello Todd,

Yes the VideoMASTER Generator software will work with the PCI-5421, even though on the website it is listed only under the PXI-5421. You will need to request an evaluation license from activate@microlex.dk which goes directly to the team that will issue you a temporary license (30 days).  Please include the serial number of the PCI-5421 in your email to activate@microlex.dk so they can issue the temporary license.

Finally if you are interested in purchasing the software, simply contact your local NI sales contact and request part number 780933-01 (VideoMASTER Generator SW only) be added to your purchase of your PCI-5421.

Let us know if you need any help as you get started with your evaluation, we will be happy to get you up and going.

Cheers,
