back to article BBC boffins ponder abstruse Ikea-style way of transmitting telly

Future broadcasting could resemble IKEA flat pack furniture - with the bits and pieces of each transmission assembled at home, perhaps in ways not intended by the designer - if boffins at the BBC get their way. The traditional approach is to mix the media before it's transmitted in a linear stream. But brainboxes at BBC R&D …

        He meant "confirmation bias".

        The blog text says "conformation bias", but the words are linked to Wikipedia on "Confirmation bias", so it's a typo - o and i being together on the keyboard.

        It's an interesting idea - but maybe easiest to deliver on a PC or similar powerful media player. I don't know if a Smart TV could do it. Hmm. Maybe with Android appearing in that market...

        Re: Interesting

        Not necessarily for the video part. In that regard, I think it's being done a bit inefficiently, though correct me if I'm mistaken. I'll admit I'm drifting from the topic at hand, but what I'm discussing seems more realistic AT THIS STAGE. Are TV video transmissions of a single quality or of a progressive quality such that the first bit of a frame produces a low resolution frame and then other parts refine it into a higher resolution over several stages like a progressive JPEG does? I would think for a more mobile world a progressive-quality stream would be more versatile without having to retransmit the same image multiple times, unless the overhead involved with progressive quality outstrips the costs of just transmitting the image multiple times.

    "But don't underestimate the appeal of O-O transmission to two groups of people. One is BBC middle management, who will form "a metadata working group" at the drop of hat, and spend years having meetings which typically achieve nothing - but consume a lot of license fee money.

      Re: hmm

      Alternatively, it transmits the meta data first, then only the media objects you select from the menu/filter system, potentially saving bandwidth transmitting unnecessary language options, scaled down resolutions etc.

      If the selection changes mid-transmission, just start streaming the new objects and stop streaming the old ones.

    Nothing new

    This is exactly how digital TV already works. A multicast mpeg transport stream is broadcast containing separate elementary streams for each video, audio, subtitle and interactive track. There is also some metadata (PAT and PMT tables) which associate which streams go together. It's not unusual for a programme to be broadcast with multiple audio streams (english, welsh + english audiodescriptive for instance) and being able to select different video streams is also regularly used for wimbledon and similar.

    There probably is scope for better metadata and user interfaces to identify what each of the streams are/package combinations together, but mostly we just seem to be in a timewarp back to when people sprinkled 'object oriented' because it is new and exciting.

    > allow "a viewer to have the programme content tailored to their taste or mood"

    Surely the way to do this would be a combination of features inside the telly?

    It would start with image and voice recognition and end up with real-time video editing / substitution. That would allow users (or viewers, in old-fashioned parlance) to choose what attributes the individuals on their TV programmes had. So if they didn't like the voice of a particular "star" they could access a menu and change the pitch, gender or accent (maybe even language, too) of the speech that issues forth from their gob. It wouldn't be a huge step to do the same with the video, so actors clothes could be changed (or removed, or covered up - the "fig-leaf" filter) and themes added. Likewise with their faces and physical attributes.

    From the broadcasters' side, this would make complaints a thing of the past. If you didn't like a programme - they it's your own fault for not tailoring it to something more palatable. Offended by the language - why didn't you use a *beep* filter?

    For the users, the possibilities are endless. Not only could you substitute Her Maj. in to do the weather forecast, but you could buy add-ons and customisations and maybe even third party mashups and reworkings.

    However, the best feature would be that there would never be the need to make an original programme ever again. Gone would be repeats in the orthodox sense. Yes, it would still be Dad's Army (special centenary anniversary edition) but Captain Mainwaring could be replaced with Arnie, Corporal Jones with Catherine Tate's Lauren and so on ...

    Of course, you'd never be able to trust a news broadcast - or any other factual programme, ever again. But the downfall of democracy is a small price to pay for a limitless supply of crappy TV.

    Really like the idea of being able to set levels of music, fx and dialogue. The standard mix is not suitable for all circumstances. For instance turning the volume down so neighbours are not awoken by explosions can mean that dialog is inaudible.

    All the elements and their directions squirted down the pipe, reassembled at the client, like a Flash animation.

    The Beeb's engineers are a damn clever lot, and always testing the edges of what's possible to improve the viewer experience down the road. NICAM, for instance, adding stereo sound to an analogue signal without breaking anything. Hey, in the late 80's they recorded the Wimbledon finals in HD to see if it could be done with first-generation Beta (not digibeta mind - predating digi by years and years!) decks - 4 ganged each recording a quarter of the signal. Impressive.

    I would imagine this is similar testing out ideas for the future. It may not even end up using conventional cameras but strip out individual elements to send. It could actually be quite revolutionary - imagine the bigger picture.

    Mpeg4?

    I thought this was exactly the point of mpeg4 (based on the multitrack 'elemental' architecture innovations of Apple's QuickTime, which has become much less interesting since): Keep the media in different streams rather than interleaving them or multiplexing them, so those streams can be selected for different audiences, devices and bandwidths at reception. The classic case is the scrolling text news ticker visible under so many talking heads. Or even movie credits. It's plain stupidity to compress text with a video codec, and yet it's standard practice today to do exactly that. Insanity! Transmitting text along with video is a solved problem! But that's not enough when the engineering and marketing agendas outweigh that of the designers and content innovators, not to mention the content industry (more correctly called the back catalogue industry) who just want to rerelease the same old cash cows in new formats, rather than let creative people do something like (say) Peter Gabriel's Xplora1 on bluray (bluray specifies that the player has a JVM, no?)

    But mpeg4's non video profiles never really took off. Largely because the content creators didn't think in terms other than the existing paradigms for what video could be. One track each of audio and video. maybe a subtitle track if you're lucky? its pretty poor for so-called 'multi'media. Others have pointed out the dearth of multi angle content. (Ideal for porn, but even those tricks fell away). Just as Marshall McLuhan observed: we first use the new media to do the work of the old. (q.v. artficial horse heads on early cars). Only later do we find out that the new media are good for something different than the old, and the old media were actually better at some things. (Books are still good).

    Most people are unaware that mpeg4 specifies a profile for 3d models and textures, or for interactivity for example (these was never implemented). Adobe (or whoever else might have made an authoring tool) had other priorities. Same with the browser guys, caught in the XHTML 2.0 quagmire. So content creators and software firms need to be on board. Therefore it's significant that the BBC is pushing this. I remain skeptical, however.
