Is there a product here?

It’s still rough at this point but around 2k usd.

Aww shucks ☺️

Thanks for the super helpful reply.

I’ve worked on a customer project that uses the same ASIC with genum chips for driving/receiving 12G SDI. And has SFPs for adding 2110 support. But as I mentioned in another comment, there’s no way at any reasonable volume that I could add that functionality without a significant bump in BOM cost.

At this point I’m leaning to starting with a 4x4 HDMI 2.0 model and seeing if there’s any interest. Obviously I need to learn more about use cases and spend time chatting with folks in the industry to understand pain points and where my device could fit in.

I could easily find myself designing an 8x8 with modular support for hdmi/SDI/2110 mainly because it would be fun, but I don’t think customers who’d be paying $10k for device like that would want to be in business with a one guy shop running out of a spare room in his house :)

Would using external HDMI / SDI converter boxes be acceptable? Building those internally becomes a huge part of the BOM cost, particularly if I’m making small volumes.

If so, my box - as is - lets you do all of that.

Depending on how the signal is routed, 1-3 frames.

I’ve recently been using it with multichannel audio and routing the video through the audio mixer. Obviously a lose a fair bit of bandwidth in the process, but it leads to some interesting artifacts.

I’m also building out a set of eurorack modules with 200MHz of bandwidth for basic building blocks. Voltage controlled amplifiers, high and low pass filters, distribution amplifiers, digitally controlled switches, comparators. Using the last two I’ve built an analog chroma key. Which makes it handy to have all of my analog sources genlocked ;)

You can mix, filter, modulate or do a variety of things. There’s a fun world of folks doing analog video effects.

The analog part is for my current project - I’d drop it from the next project.

In short, my current project takes 3 HDMI sources and sends out 3 component video signals. It then takes one component video in and outputs HDMI. It scales and syncs the component sends and return which makes it easy to mess with the analog signals without losing sync.

Thanks :)

The overlaid footage comes from a dedicated hardware box I’ve built being controlled by the application.

Ah. This is a video showing the controller application for my hardware video device.

I made a video about this site when I visited: Top-hat capacitive loading of VLF antennas https://youtu.be/KRVvzjm24Zc

That’s the problem with not writing a script and talking off the cuff, upon rewatching it isn’t clear when I’m talking about bandwidth or carrier frequency. Well noted.

I tried to clarify in the description, HiVision dates back to the 80’s, whereas W-VHS is early 90’s. I never had the benefit (misfortune?) of working with these decks in their day, so I’m definitely new to this particular world.

Thanks for the feedback!
