I love these sort of challenges but I guess the answer from noggin is the way to get these HD recordings from a freeview transmission stream, I imagine with some research it's possible with Sky as well.


For domestic use - yes - recording the streams yourself outside of the Freeview/Freesat licensed ecosystem is the easiest solution.

However in a broadcast environment, it's much easier to arrange to disable HDCP en route to an HDMI to HD-SDI conversion... (Which also allows easy recording of encrypted Sky and Virgin Media content)

And yes - Hollywood studios hate this. And yes - Hollywood studios are also major customers for Blu-ray players with HD-SDI outputs that use HDCP disabling HDMI to HD-SDI converters - as many high-end cinema projectors don't have HDCP and are fed HD-SDI...

Yes - though the tour is VERY US-centric, and implied that TV was invented in the US when I did it...

What is interesting is how the main 30 Rock building was effectively built for Radio and not TV - and so some of the TV studio spaces are actually quite compromised.


No offense but what do you expect on a tour of a US based TV company.


I kind of expected a TV company with a news arm to tell the truth. The guide basically said TV was invented in the US and NBC was the first in the world to do it...


Don't mind US firsts being discussed, and wouldn't expect the BBC to be referenced - but the BBC did get there first with a regular (and by that time, all electronic) TV service starting in 1936... Saying NBC was the worlds first TV broadcaster? Wouldn't expect that...

I've done tours of NHK in Japan, SVT in Sweden, NRK in Norway and quite a few other places. They all correctly referred to the BBC AND their own history... It all felt a bit parochial at NBC if I'm honest.

They do. I managed to extract an HD recording file from my Humax Freesat box, and ftp'd it to a friend with an identical box, but the file wouldn't play for him.

20 years ago I could have lent him a VHS tape of the programme he missed. That's progress ! Razz


You could probably still play the recording out over composite to VHS and send it to him - unless they still put Macrovision in...


In the end I fed the SD Scart output into my DVD recorder and made a recording, although trying the same trick with an HD recording on my Humax You View DTT box doesn't work, so its output has some form of MV spoiler?


Yep - cheap HDMI to Composite downconverter always comes in useful... (HDCP is a different matter - though if you know what you are doing it isn't an issue)

I've got an RGB SCART to HDMI upconverter which can be useful in some circumstances too (it will also do a dreadful frame rate convert allowing 50Hz content to be played on 60Hz-only displays - which can be useful in North America)

The Rockefeller Center certainly is amazing. I'd definitely recommend the NBC tour to anyone who makes their way over there - we got to go into the studios for the Nightly News and SNL, and we just casually walked past Mike Tyson as well.

For whatever reason, last night's episode is not yet available on BBC iPlayer. Is there some technical or legal reason why it hasn't been uploaded yet? It's usually up within a few hours after broadcast. I missed the show last night. Did something go wrong?


The dogs in the studio had name tags and these have been blurred out on iPlayer. So not anything relating to companies investigated.


I wonder if they had readable addresses on them.

Wimbledon 2017

That was done Summer 1980 for the Moscow Olympics BTW, but only for the main evening opts (here in the South there were two five second breaks on 1 and 2 just before and just after the each evening show, while they presumably re-patched the opt chains (Different times I know, and I think the first time BBC 2 in England had had regional opts ?)


Some regions had two opt-chains and two-sync chains at one point - so the two galleries that many regions had could opt-out of BBC One and BBC Two simultaneously - though areas like graphics, VT etc. had to be locked to one sync chain or the other (with a change-over switch to select which)

Any Freeview HD branded device that records to external media will add mandated DTCP (I believe - not sure if other encryption is allowed) encryption to HD recordings, to make sure they can only be played on the device that recorded them. (In fact I believe it has to do the same for internal storage too - so you can't remove the hard drive and play them/copy them)

The Freeview HD broadcasts themselves aren't encrypted (the Freeview HD EPG data is compressed using proprietary Huffman tables though) - but Freeview HD licensed devices must add encryption to recordings.

These two measures were introduced to allow Freeview HD NOT to be encrypted for broadcast (they were deemed - good enough for rights holders)

If you have a non-Freeview HD licensed recorder, or use a PC with a DVB-T2 tuner, this is a non-issue - the recordings are clean, unencrypted, and play in VLC, MPC-HC and most other players. (,TS is the most common recording format - as it is basically the MPEG2 transport stream that is being recorded with PIDs carrying AAC audio, H264 video etc. NB MPEG2 TS doesn't mean the video is MPEG2...)

(I believe the same rules also apply to Freesat HD devices)

I don't know, but I imagine that the fact they don't charge for individual clips might also mean that they don't limit access to the content pool.


Historically neither APTN nor EVN nor Reuters charged full subscribers on a clip by clip basis - but you had to respect the slates. (APTN used to carry a lot of "Sky - no access BBC" and I think Reuters had "ITN - No access BBC", as occasionally did EVN...

APTN and Reuters had separate deals for some specific feeds (SNTV and Showbiz) that only certain BBC outlets subscribed to - so everyone knew not to use content on those.


I think with CBS, ABC and others being associate members of EBU, they might have had to pay an additional fee for the clips they used.


Yes - but full members, like the BBC, don't (or didn't)...

We might want to hold our horses on tonight being the last 100 Days+ as Christian Fraser said at the start that they were singing off for the summer-So a Summer break and then back in the first week of September then?

Hopefully with better name.


I don't understand why they're going on summer hiatus - there's so much news going on both sides of the Atlantic. If it's a matter about holidays why not stagger the anchors schedules. Then again it does seem like many U.K. news shows go off air for a few months this time of year.


Lots of shows go on a summer break - particularly UK political shows. (Mainly because the UK Parliament goes into recess. Do US political institutions like Senate and Congress have a summer break?)

Given the nature of the European News Exchange (ENEX), I'm not sure that's possible.

Members pay a yearly membership fee. Members submit material to the content pool, but they are not allowed to charge for it. But they can use all material in the content pool, free of charge.

CBS are already an associate member of the EBU, so they might have to pull out of ENEX, but given all that access to free material, they might not want to pull out.


Does ENEX not have exceptions - like APTN, Reuters, EVN etc. had - where certain content is slated to point out some broadcasters don't have access?

International News Presentation: Past and Present

Suspect the big difference between the BBC and the TVQ sequence is that I believe those BBC opening title graphics were generated electronically live (both key and fill), rather than being played from VT, hence the nice clean keying on the BBC sequence. (The BBC titles generator was slaved to the 1/4" audio tape playing the opening title music)
