Goodbye TVC

TVC

Disclosure: I’ve worked on-and-off for various bits of BBC for many years.

The closure of TVC is one of those left-brain/right-brain things: The logical “right-brain” spreadsheet lover in me looks at the old building, the amount of asbestos, the legacy cables and the fact that News, Sport & Childrens have all moved out and thinks that it’s the right thing to do.

Meanwhile the left-brain in me is screaming loudly “BUT IT’S TELEVISION CENTRE”, it’s a place of dreams, of wonder, where I was in a small room in the basement while they filmed Jools Holland above. A place I got lost deliberately at lunchtime just so that I wouldn’t get lost that one time I was running for a meeting.

The truth probably lies somewhere in-between; News being in West1, unified with world-service is a great thing for the output. BBC Worldwide and BBC Studios will be moving back in a few years. Studios 1-3 will survive.

So on this, the last day the building is still in general operation, I will think fondly of the past, and hope that post re-fit the building emerges leaner and all set for 21st century.

My friend wrote about his recreation of a famous moment: On Tap-Dancing at TVC.

The New ITV News

itv.com/news relaunched this week. It’s now all of ITV, and not just the ITN national bulletins. It’s very nice. Lots of people have been talking about it. I’m late to that party.

Itv news site audacious invention from necessity of having v little content and no way of competing with depth – turned into a real virtue

BBC/Guardian, et al feel like a curated library. ITV now feels like a twitter-stream, or as Paul said like tumblr.

It feels very “now”, you’re seeing the news of the moment. It’s not going to replace BBC News as my homepage, but it’s good to see ITV competing meaningfully, innovating not aping.

Pessimistic about TV Apps

I was on an episode of Tech Weekly today (23 minutes in) talking about Connected TV alongside the head of the DTG, Richard Lindsay-Davies. I was perhaps a bit down on TV apps and wanted to expand on that a little, in the hope of being more nuanced.

I think that Video Apps on the TV video are great: I love using iPlayer and NetFlix on my TV/PS3/AppleTV far more than on my laptop. You can glance away, and glance back when something interesting happens, in the way you watch TV. You’re not cmd-tabbing through windows to try and find the iPlayer tab before the interesting bit ends.

The BBC Olympics application will let fans have access to nearly all the sports, not constrained by how many channels the BBC has – a useful extension and I think it will be popular. The Twitter app on my TV? Not so much, I used it once, and used it to say how awful sending that tweet was.

I really don’t think we’ll manage to have that many TV-only apps. No developer without lots of video (the Broadcasters, Netflixs and YouTubes of the world) is going to pick up a TV SDK – they’re going to learn Android or iOS programming. There’s already a lot of fragmentation in the TV space and billing is never going to be as easy, and lucrative, as on the mobile platforms.

I think that in the future we’ll see some of these phone/tablet apps throwing interesting graphics and content to the TV screen, like the scores at the end of a round. There’s scope for real innovation here, but it’s about feedback, not interaction.

The TV should be the easiest screen to get content on, you shouldn’t have to think about how you get content there: It’s about leaning back and relaxing. We tried ordering pizza via TV in 1998, it didn’t really work. Today we’d just do it from our tablet or smartphone.

Have a listen, let me know what you think, am I being too pessimistic?

Farewell Radiotalk

At the end of the coverage of the Radio Festival, Trevor Dann revealed the weekly podcast is no more.

I’ve never really worked in radio beyond running a mixer evaluation for Radio2 (the glamour), but RadioTalk often left me wishing I had done. It had a decent range of voices on, the roster was the right size that you could remember most of them. Even industry big-wigs like Tim Davie popped in from time-to-time. It had the pleasingly conversational tone of good radio, and combined with the occasional fuck-ups around the Academy-MDF as previous the non-studio studio was known, was an accessible listen to an outsider.

Anyway, thanks to Trevor and (long-suffering?) producer Heather Davies for creating something good for the last few years.

On the Beta BBC Homepage

Standard “I used to work for the BBC” disclaimer applies.

Over at beta.bbc.co.uk you can see the new BBC homepage. The BBC have written a few articles about it.

My first impression is that this the first homepage that has done what the home-page needed to do, be a shop-front for across the BBC. Previous home-pages have always been very silo-structured. News had their bit, ditto Radio, Sport, Weather, etc.

It felt like representation of the org-chart rather than conveying the breadth of the site.

The new one feels both busier, and simpler. Without the excessive and technically unreliable customisation it’s lost that horrible of air of “is it a homepage or a BBC specific My-Yahoo?”.

I love the design, it’s a clean grid structure and I really hope that as the Ten Products are launched, they can all share this sharp-styling which is a great evolution of the GEL design guidelines.

The BBC has perhaps been through a few too many home-pages in previous years, but this one feels like it’s been given a really tight scope and done that – most people will still be browsing to bbc.co.uk/news or finding content via Google.

A gripe though, given they’re linking so much to iPlayer things, they really need to make the correct redirect to the TV/iPad “big screen” iPlayer version of a programme and not a link to the front-page. (Oh, and sort out an HTML5 player for News content)

Big things are obvious, but sometimes smaller things niggle as much

I love my AppleTV, it’s the easiest way I’ve got to get music playing on my TV, which is the way to get music through my stereo.

The only thing that could make this nicer would be if Apple more fully used some of the features of HDMI. While I’m not really a fan of HDMI, it does have some useful things in it.

My PS3 can trigger my TV to turn on, or to change input to display it through the use of HDMI’s Consumer Electronics Control¹.

The AppleTV doesn’t send any signalling: meaning that every time I’m sat playing music from my Laptop or iPad, if my TV isn’t in the right state, I have to find the remote control (or even worse stand up from the sofa).

It’s minor. Totally minor. But when I get this gripe most days, and when I know the thing sat beside the Apple TV can do this, it’s annoying.

People notice big things that are wrong in products, and complain about them vocally – but small recurrent niggles also wear down consumer satisfaction. It’s the only thing I really don’t like about my Apple TV. I forgive it not playing non-iTunes content, and its lack of favourites on radio stations.

I know it’s unlikely, and I don’t even know if the hardware supports it, but it would be lovely if an option appeared in settings after an update “Change TV input when Apple TV starts”.

Pretty please Cupertino?

Consumer Electronics Control signalling allows the device to prompt the TV, and also for the TV to send remote key-presses to be processed by the device – allowing me to control my PS3 with my TV. Controlling devices like that can end up more a confusing novelty for anything more than basic 5-point navigation ↩

Hashtags as plausible deniability from compliance

Various broadcasters have done “chat around content” applications: the Apprentice and The X-Factor being two examples. These are expensive to run, because the second the content is on bbc.co.uk or itv.com then you face the wrath of compliance.

This is not a compliance rant, broadcasters need compliance, and at its best it helps programme makers get the most out of their rushes. It is an overhead though, and given we’ve yet to really see how we can “monetize” those people talking about shows, is it worth paying that penalty for highly vocal, but very small minority?

Enter the hashtag: Now shows have been transmitting with cues of suggested hashtags for many years. Now really only used on Twitter, but you could argue that a tag is really a platform neutral way to flag your content.

You’re not hosting the discussion, which means you’re not paying for moderation, and you’re not liable for the compliance. The broadcaster is saying “you guys can go and huddle over there, but it’s not really anything to do with us, understood?”

This has implications for second-screening because I think it means that broadcasters are going to be loathed to actually build wide-scale chat-around-content style applications: their name being associated with it just causes too much expectation. Can you imagine installing the “BBC Socialiser” app and getting the “THIS APPLICATION MAY CONTAIN BAD THINGS” pop-up from the iTunes store? It’s not what people would expect from the BBC.

Most people are still lazy, lean-back linear content consumers – the TV is a familiar friend at the end of the work-day who doesn’t expect much response, but over time people will want nicer ways to contextualise their tweets about content.

And so to the meaningless predictions…

Much as they will be loathed to let go, Broadcasters will realise that they can’t justify self-providing these services, and they will give more data away about schedules and items on-air in a form that can be better used to tag content by 3rd-party services
Services like Facebook, Twitter and Google+ will provide ways to embed this metadata in posts, so the a unique identifier of a show could be associated with a post, in a similar way to geo-tagging appeared.

The combination of those two things mean that you could create an app that was specialised twitter client. I don’t want a new social network for telly, but a client that embeds the magical codes to make everything more findable feels like a workable compromise.

Multicast for File Delivery

James Cridland wrote about how broadcast was a potential way to distribute Lion, the new version of OS X. While digital broadcasting is compelling as a mass-distribution media, the logistics don’t stack up to my mind, and while tuners are getting quite cheap, the hassle of trying to get aerial signal to your computer is still there.

Multicast was briefly mentioned in the comments, this provides a much more realistic alternative, and is something that BT, the main ISP Wholesale provider, is implementing. This post covers ISPs that use BT to provide connections to their subscribers, the method most ADSL customers are provided by. Customers with Sky (who are Local-Loop Unbundled) or Virgin (who run a cable network) are on different network topologies.

What is multicast? Basic machine to machine communication is unicast. Broadcast allows one machine to ‘talk’ to all others. Multicast is somewhere between, where other machines can choose to listen to stream on the network, but without the “speaking” machine having to transmit at additional copy. It’s perfect for things like live Radio or TV viewing, where many hundreds of users are viewing/listening to the same thing.

Where are we today?

Most ISPs don’t support multicast, so every download or action on the internet is a separate stream:

The ISPs that do support multicast have to split it before it goes to BT. The BBC multicast some content out as a trial, and the traffic looks something like this:

The ISPs save on their ‘transit’ bandwidth, but still have to inject a separate copy of the video for each person watching when it goes to BT. Transit costs are unfortunately the cheaper part of an ISP budget, which means that multicast doesn’t help ISPs that much at the moment.

BT are introducing multicast into their network, which means that the “splitting” of the multi-cast to uni-cast occurs much deeper in the BT network, which means the result looks something like:

Much more efficient, only one copy of Radio1 goes from the ISP to BT (and some older BT documentation implies this may even go directly to BT bypassing the ISP).

But how does this apply to a ‘file’ like Lion?

If you were to treat the 4 gig Lion update as a broadcast you could transmit it as a “carousel”, where it loops around. Run multiple carousels at different positions in the file and a client would join 1 or more streams based on the amount of bandwidth available, and how much of the file was downloaded

For efficiency, you might also want to offer streams at higher bit-rates so that a client could join fewer streams.

This traffic would need to be flagged as lower priority. TV multicast will be the opposite, and have Quality of Service to make sure video plays back smoothly, here though you would want the download to be dropped if other traffic was present. This will leave you with “holes” in the download.

The client could wait for the broadcast to “come around” on one of the streams and join that appropriately, or it could also make direct connections back to the CDN, or use Peer-to-peer networking, to “mop up” the specific bits of the download it had missed.

Would it make everything faster?

Yes, and no. It would definitely be more efficient, however the limiting factor will still be the copper at the end of the journey, between the exchange and the customer. However, by reducing the demand to both the CDNs, and the ISPs bandwidth, that last mile should be used more fully.

Will it happen?

For things like downloads using CDNs that are embedded deeper in the network would be simpler for the client, and ease the load on ISPs. After the initial download “flurry” the multicast approaches efficiency reduces.

Two things make it more sense for video content like the BBC iPlayer: you have many people downloading content as it is being released, and you have a custom download manager in place.

Multicast will definitely happen for live-content. For other content it probably remains an interesting thought-experiment, unless the economics proved compelling enough. That is less likely since those impacted (the ISPs) are not those able to make the changes (Content Distributors).
