Absolutely amazing. Playing around with the math and own FPGA and hardware implementations of Analogue TV, as what I thought would be a totally niche hobby, I would never have dreamed to see a UA-cam channel that not only has this as its primary topic (other than one-off videos explaining how TV used to work in broad strokes), but that does so in such meticulous detail. Thanks a lot!
I'm beyond fascinated by this, and in such awe at the technical prowess on display here, pun intended. But for Christmas, I want a video that explores how one would go about designing such a device, from scratch, as if there was no such device before. What components do what, and testing what chips would provide what result. I realise this is basically a thesis, but still!
I hear you. Well I do have one more video like this in the pipeline but as for building a project from scratch. I just can't commit to it at the moment. I am mostly focused on making these videos unfortunately. I would have to stop for several months to get the necessary time.
If you are interested Matt? I am doing a CQ-TV article on my new hybrid NBTV system, that is based on the old B-MAC format. You might find it interesting on how it works and the small amount of RF bandwidth that is required for transmission.
While I can understand why you might want pro-grade hardware to generate an _analog_ test pattern, due to all the signal quality and genlocking issues you mentioned - what's really the point of all this expensive equipment for digital signals on digital TV? How will a digital test pattern generated by something like a PT5300 differ from just playing a video file or running a simple program on a PC or something like that?
PT5300 is primarily an SPG not a test pattern generator. For a studio TPG even in digital you would want it in an SPG not a PC. Bear in mind the design was mostly completed in 1997. Quite hard for PCs of that era to generate digital TV signals real time.

Thank you so much for this, it got here in one piece and everything's working perfectly.
Love how much work goes something as “simple” as a test screen. I still remember them from my childhood when there was nothing on-air. Good job!

Always interested. Send over the info once it's complete!
Superb; just love it. Well done.
I've been looking at something vaguely similar to your ADV7393 thingie using a second hand ADC7171... so this is going to be interesting.
Just had a look. Looks to be a predecessor of the ADV737x. Maybe near end of life too? But an easier package to deal with!
@@mattstvbarn "easier to deal" with sounds good to me... I'm so not ready for the monster builds you're doing. ;)
More! Give us more of this awesomeness!

Love the video. Would have liked a "headphone warning" at the end ;)
Sorry. I learned my lesson.
