That's correct - 608/708 is North America only, and UK/Europe could use OP42/47 teletext for simple captions (not whole magazine), and/or DVB (mostly language translation).

I was talking about the older PAL-based teletext as well - but you're right, I understand it was different in terms of equipment originally with the full-screen data feeds. Separat…

In my experience with a few big broadcasters like Paramount (previously Viacom) and Discovery, for broadcast in Europe/UK the signal they generate often has a mix of Teletext and/o…

There are very strong lobbying groups that push for accessibility in terms of captions (as well as the “DV” described video audio track) but my impression is that their focus is on…

Live closed captions (text only) is very common and standard. Usually those are done by an external company listening in to an audio feed, and sending the data back. It used to be …

The older “608”[1] system in North America was much simpler but the current “708”[2] standard does support specifying colours and fonts, but in my experience in the industry nobody…

The type of system I was referring to is the core within the broadcast facility, rather than extending to the home viewers (which is a separate downstream distribution encoding/mux…

The company I work for is in the SDN space but specifically around large scale uncompressed (SMPTE 2110, 1.5Gbps per HD stream) video broadcast IP infrastructure rather than relate…

Would be nice if there was a more granular option for access to photos which allowed "image only" with no metadata... I assume most people don't realize when they grant photo libra…

We also do full systems purely in software at large scale, such as this one; https://evertz.com/resources/press/Discovery-Cloud-Oct2017.P... ... fully virtualized in AWS, not just …

Challenges are mostly around keeping lock-step timing across a lot of separate devices in the system at scale (using PTP) for frame-accurate switching, and working through getting …

My company is heavily involved in this area... there is a migration underway from baseband ( https://en.wikipedia.org/wiki/Serial_digital_interface ) to fully IP based infrastructu…

I'd be very interested in any details of your approach that you could share. I added another comment to this thread with the details of what I've been working on for professional s…

This is great. I write 100-200 page functional spec documents at a vendor for large scale file based broadcast systems (10-300 linux servers) for a number of customer projects, and…
