RS-343 Video

I have a customer looking to capture RS-343 video (high resolution monochrome composite video used primarily in mil/aero) and wanted to know if we have any parts that have been used to do this? I was thinking maybe the ADV7181C could do the job but am looking for some sort history that the part can be setup correctly for this standard?

I also noticed the ADV7128 supports RS-343 as an output, so there must be a complimentary part to bring the signal in? Any insight would be useful as I am relatively new to the line... Thanks!!

  • I can’t find a lot about EIA 343 in terms of what exactly the details are. It is a monochrome high definition spec. This is what I did find:

    RS-343 was introduced later than RS-170 and intended, according to the title, as a signal standard for "high-definition closed-circuit television", which among other things reduced the signal amplitude to 1.00 Vp-p. The signal specifications according RS-343:

    White: +0.714V Black: +0.054V Blank: (0V reference) Sync: -0.286V.

    RS-343 specifies a 60 Hz non-interlaced scan with a composite sync signal with timings that produce a non-interlace (progressive) scan at 675 to 1023 lines.

    This standard is used by some computer systems and high resolution video cameras. Precision imaging systems, infrared targeting, low-light TV, night-vision and special military display systems, usually operate to high-resolution, RS-343 standards (875-line, 30-frame scan). They require specialized and costly recording and display equipment.

    Given that, our parts are, in general, color. You can decode to Y Cr Cb and only use the Y component. There are no scripts available specifically for EIA 343.
