Yep - suspect the US releases are 50i to 60i domain conversions, even though the source material is shot 25p. As a result the motion interpolation algorithms used in standard 50i to 60i conversions...

I guess the main difference is that there is a national pay-TV OTA system, that delivers a decent number of services (often the majority of European OTA services are pay-TV, with just the main public...

In Germany they are switching from DVB-T SD MPEG2 16:9 (576i25) to DVB-T2 SD/HD H265 (540p50, 720p50 and 1080p50) Commercial stations that were free-to-air in SD are switching to encrypted pay-TV on...

"Class" was a commission for BBC Three - which is online only these days (no linear broadcast channel) and aimed at 16-25 year olds. It got a repeat on a linear channel (BBC One I think)

Thanks - that makes sense.

In Europe we have an interesting situation where at least one DVB-T platform operator uses DVB-S2 to distribute to the transmitters. They pre-encode and create a full...

I think demodulation is how you get data from the RF broadcast isn't it? It defines things like the number of COFDM carriers, modulation schemes (QPSK, QAM 16, QAM 64, QAM 256) and whether you allow...

I think you misunderstand me. DVB-T/T2 boxes on sale in the UK are also 'hardware based'. They have hardware tuners and demodulators (you can't add new demodulation standards via an OTA update), and...

That must be a US-thing.

The EBU thinks pretty much the same. Better pixels not more pixels... (And yes I know 1080/60p is more pixels/second than 1080/60i - but it's not as many as 2160/60p...)

Yep - but Blu-ray is limited to 1080/24p too... It doesn't support 1080/60p either.

For demanding content...

Eh? The US doesn't broadcast any 1080p OTA does it? There is content that is shot 1080/24p (*) and 1080/30p that is converted to 1080/60i for broadcast, usually using 3:2 and 2:2 pulldown - but...

I don't believe - in most cases - that is the case. You need to decompress to a number of clean frames to allow a totally different type of codec to work. Imagine going from XDCam (Long GOP 50Mbs...

Though that's a moot point - as even if they don't physically decode to HD-SDI, chances are the recompression from 50Mbs to whatever the playout codec is at the station will take the video via an...
