Getting Bits to Boxes

Okay – here’s a throwaway post for the weekend – a quick sketch of a thought experiment that I’m not going to follow through in this post, though I may do in a later one…

  • The setting: “the box” that sits under the TV.
  • The context: the box stores bits that encode video images that get played on the TV.
  • The thought experiment: what’s the best way of getting the bits you want to watch into the box?

That is, if we were starting now, how would we architect a bit delivery network using any or all of the following:

1) “traditional” domestic copper last mile phone lines (e.g. ASDL/broadband);
2) fibre to the home;
3) digital terrestrial broadcast;
4) 3G mobile broadband;
4.5) femtocells, hyperlocal, domestic mobile phone base stations that provide mobile coverage within the home or office environment, and use the local broadband connection to actually get the bits into the network; femtocells might be thought of as the bastard lovechild of mobile and fixed line telephony!
5) digital satellite broadcasts (sort of related: Please Wait… – why a “please wait” screen sometimes appear for BBC red button services on the Sky box…).

Bear in mind that “the box” is likely to have a reasonable sized hard drive that can be used to cache, say, 100 hrs of content alongside user defined recordings.

All sorts of scenarios are allowed – operators like BT or Sky “owning” a digital terrestrial channel; the BBC acting as a “public service ISP”, with a premium rate BBC license covering the cost of a broadband landline or 3G connection; Amazon having access to satellite bursts for a couple of hours a day; and so on…

Hybrid return paths are possible too – the broadband network, SMS text messages, a laptop on your knee or – more likely – an iPhone or web capable smartphone in your hand, and so on. Bear in mind that the box is likely to be registered with an online/web based profile, so you can change settings on the web that will be respected by the box.

If you want to play the game properly, you might want to read the Caio Review of Barriers to investment in Next Generation Broadband first.

PS If this thought experiment provokes any thoughts in you, please share them as a comment to this post:-)

    This guy discusses a new networking paradigm which he proposes to alleviate the duplication of traffic around the internet at the moment. Given the relatively high volume of a piece of video media (compared to, say, a blog or website) I think this should be part of the same discussion as getting bits to boxes. I think it represents a more efficient way to use our existing infrastructure. If you’re going to watch it, you kind of need to watch it all. It isn’t just local cacheing and multicast.

    Hope you enjoy it.
