making that out of discrete logic is impressive

This one is really interesting. Neil Hinson (Chief Engineer) designed the first one because we were about to go to NAB and I was about to interface an Encore DVE to the first digital tape recorder for CCIR601 live on the Sony stand. We wanted to be sure it would work (parallel) with all the timing etc. correct so Neil designed this. The most useful bit is that the blanking/timing data was shifted both horizontally and each showed the difference between correct and not on a monitor, so problems were obvious. Later we used it for ram checks etc in the whole range. Brilliant. The display shows a complex CRC so that both position and data errors show as unexpected numbers.

You are lucky to have the CCIR 601 version this was generally only used in the R&D department. In the turnpike test department we only got the CCIR 656 parallel analyser.

Very cool piece of kit. I remember drooling over what Quantel boxes could do back in the day. It especially warms my heart that this was done entirely with discreet logic! No wonder the thing has a Logic analyser ribbon cable and connector :-)

So cool that they manufactured their own internal test-QC gear as nothing on the market met their needs. Also, you're brilliant, Mark.

Wow, all made with TTL logic and no software. Impressive feat!

yes! new dexter video! ...and about my favourite tv graphics company!

RS used to sell those cases - maybe made by vero?

Many thanks to Yunohū Uwhárre (fascinating name, is that Inuit?) for providing this hardware for our knowledge and entertainment.

The Ancilllary headers would have been used for embedded timecodes and possibly closed caption data

Is that a BPMC sticker on that PVM? 👀

I remember Newbury Terminals - probably not relevant

I am 11 and hopefully if you release a emulator for this ill make my new channel intro using this!
