Philips pattern generator [Threads merged]

Thanks to you, you also have PM5544 and do you have a TV control room in BECG?

Please look at our website. The newsletters here: https://becg.org.uk/newsletters/ are a good record of our progress. The Broadcast Engineering Museum is developing rapidly with new areas to visit during our next open days on 14/15 September. One of these is a control room, though it won't yet be hooked up to a studio with cameras.

If you're in the UK please make contact and we'll try to arrange a visit.

I watched Inaxeon's clip and asked him too and he said there are PM5534 and PM5644 which are two vintage Philips pattern generators.

I know that the PM5534 and PM5644 exist, but we do not have them at the Broadcast Engineering Museum.

Thank you, and how to create a replica of the Philips pattern generator (PM5544) from scratch based on the original model? Because I have to study broadcasting engineering.

@sickdear I know that English isn't your first language but I'm finding it difficult to understand exactly what you want to achieve.

Building an exact physical replica of a PM5544 would be almost impossible. It would also be very difficult to build physical replicas of later generators.

If you just want to generate the pattern using modern hardware there are several ways to do it. These include R-Pi as suggested by Mike Watterson.

Also the PM8546 logo generator is an extension of the PM5644. I tried to find the PM8546 font but it's hard to find because it's in all EPROMS and Inaxeon has written the code on their GitHub and I tried to get the code to replicate it all but I don't know if I can do it.

Hello,
I'm here to ask about broadcast engineering and creating broadcast graphics that are vintage, whether it be EPROMS or Raspberry PI, whatever it is. But I have to say that I would like some tips on how to create them, such as clock on screen, lower. third, CG, clock ident, etc. because I tried to create it but couldn't.

Try making animated SVG in Inkscape (programming a clock is harder) or static PNG in The Gimp. Using gif or mpng for a clock would be wasteful,

Put on a Raspberry Pi. Make a panel with buttons and a ribbon cable to the RPi's GPIO port.. Then any suitable script or program to read GPIO button state and show the images, either in HDMI HD, QHD or 4K or on the PAL/NTSC composite port (the RPi4B has this and stereo on a 4 pole 3.5 mm socket, the RPi5 has the composite on a pair of pads and needs USB audio for sound. The 1st HDMI port does HDMI audio.
