Re: [backstage] What is TV?

2009-12-15 Thread Ant Miller
Not definitional but:

TV is a large international engineering, entertainment, and journalism
complex with a contiguous attitude toward it's 'audience' and in most
cases, it's 'customers/clients'  (aka advertisers).  It is a culture
under threat, and reacting to that threat with several contradictory
trends- a flight to quality and niche (think HBO and the abandonment
of the mass audience model), a flight to immediacy (think 24 hours
rolling news) and a flight to audience centrism (think ultra local TV
and the cult of UGC).  These reactions and more are pulling apart the
consensus at the heart of TV- there is no perfect TV anymore, if there
ever was.

What was 'perfect TV'?  It was the idea of commecially sustainable
programming of a wide range and high quality that utilised steadily
advancing technology to deliver better pictures and sound to more
people and to build ever larger audiences.  It was not more choice.
It was not revolutionaly technology.  It was not a technological
fracturing of the audience and their devices.  Perfect TV is dead, and
to tell the truth it never really existed anyway.

Institutions like the BBC (and RAI, RTE etc.) were anomalous in the
global TV industry, and we need to recognise that.  We need to
understand that on a global scale TV is commercial, and the BBC then
as now oppoerates along side commercial partners in terms of
technology and content.  The two key differences are that we don't
carry adverts (and so do not have the 'client relationship' that
defines most of TV) and that we have, instead, developed a strong
social contract.  As the technology changes in the global market throw
TV globally into turmoil, we will be thrown into turmoil too.

TV is what mass communications and publishing was before the internet
reached most people's homes.  TV the industry- the industrial/
entertainment/ journalism complex- is trying very hard to move into
the internet enabled world, but whether it will successfully do so by
porting most of it'sbusiness wholesale into the IP delivered
infrastrucutre (a la Hulu/ iplayer) or my being an integrated and
enriching element of the whole integrated mesh of digital objects and
relationships (which can btw include the content that is bottled up in
products like Hulu) remains to be seen.  Arguably, the internet could
by sheer technological evolutionary pressure democratise all content.
But that in itself is a threat to the web of business that TV is
bringing to the party.

TV is a dinosaur sleepwalking off a cliff.

 For me, TV is broadcast video, which is to say, TV is video that a

 To paraphrase McLuhan, as the medium of our time - computer networks -

 every aspect of our personal life, the way video is disseminated is
 changing.

 TV is still possible with the internet, but it is a very minor way for
 video to be published.

 Just as theatre is still going, but in a very minor way compared to
 the prominance it had because electric technology.

[backstage] embedding API for iplayer in webapps?

2009-12-15 Thread Dan Brickley
Hi folks

A year or two ago, there was a nice proof of concept showing iplayer
embedded within Facebook. And there was inconclusive discussion here a
while back about APIs. What's the current state of art?

Context: In the NoTube project, I am looking at possible lightweight
standards for connecting smartphone remotes with Web-based video
sites, so that pressing pause/play/rewind/fave/tag etc on your
handheld can be communicated up to a javascript/html-based player.
I've been testing XMPP so far, and using the XMPP BOSH spec for
linking up to the HTML/.js stuff (via Strophe.js). I'm not yet
convinced this will be responsive enough for real use, and want to do
some tests with real video and radio sites.

Having made some quick mockups with HTML5 video, it was quite fun
being able to have an iphone app flip between videos running in a Web
page; however it was also pretty annoying when the XMPP connection was
too slow. I think it's time to make some more realistic tests, and I'd
love to try something with iplayer if that is possible now or soon...

Pointers? plans? is there any kind of API usable now? searching around
I couldn't find much...

The stock EMP embedding code, last I looked, can be tweaked to show iPlayer 
programmes instead of the news clips, etc., it’s supposed to be used for (this 
is entirely unsupported, of course).

However, I don’t know how much interactivity it affords from the JS side of 
things. HTML5 video, QuickTime or (failing that) a custom player is your best 
bet.

XMPP seems a bit heavyweight for this.

On the device side, send a GET a request to the 
http://server/endpoint/action. This is, curiously enough,not far off what 
the iTunes/Apple TV remote protocol is like.

Have the endpoint push the action into a queue which is delivered to the 
desktop player page using whatever flavour of technology IPC you desire 
(obviously if it’s a multi-threaded appserver you can just tack the events onto 
the end of the queue in-place…)

It won’t work in IE, but you could look to multipart/x-mixed-replace with a 
plain text or JSON payload via an XMLHTTPRequest connection as an efficient way 
of pushing events to the client from the server (with appropriate handling such 
that if you hear nothing from the server after a while, you open a new polling 
connection—I’d maybe have the server send a null packet every 15 seconds or so 
just to indicate that it’s still alive).

By 2000, you could just about do it, with huge amounts of investment - 
tens of billions?


In 2010, it's an annoying amount of infrastructure, and there are many 
bottlenecks in some parts of the country.


In 2020 - several megabit bandwidths will typically be available to most 
peoples phones, and certainly not a problem for several peoples streams 
to the home.


In 2030 - 'Now - your grandparents used to all sit down at the same time...'

Going from now to then is going to be the fun part - and the only 
certainty is that lots of people will lose their shirts along the way, 
and government will feel the need to 'do something'.


In 2030, I don't see any drivers that will lead away from the majority 
of the market being pay-per-view in some form.


This does not quite mean the death of channels.

For example.

7AM on a monday - the new Dr Who - series 24 episode 13 becomes 
available for bidding.


There are several sorts of rights that purchasers can buy.

They can buy regionally exclusive rights - for example - a channel can 
buy the right to show Dr Who in the UK over the next 3 days for all 
their users for 5p/copy, with any other channels paying 20p/copy if they 
wish to show it during the 3 days, and individuals paying 30p.


Individuals can also purchase the rights to watch - if you want to watch 
on monday, it's going to be more expensive than if you wait 8 weeks.


It can be cheaper for you to purchase a channel package, which will have 
adverts targetted at you as digital product placement in the program - 
the dalek will have a BQ, Lidl or Ikea toilet plunger on it.


You may even have premium and non-premium channels - where the 
non-premium channels pick up everything after a week.


Then, you will I suspect have the government effectively bidding on 
certain classes of program, the 'crown jewels'.


I'd also expect some programs to be 'shareware' - where viewing is free, 
and you can pay what you like at the end.

If the program makes money, it keeps getting made.

And many other forms of distribution.

Re: [backstage] What is TV?

From the International Telecommunications Union Radio Regulations:

Television: A form of telecommunication for the transmission of
transient images of fixed or moving objects.

(where 'telecommunication' is defined in the annex to the Constitution
of the International Telecommunication Union as: 'Any transmission,
emission or reception of signs, signals, writings, images and sounds or
intelligence of any nature by wire, radio, optical or other
electromagnetic systems.')

Note that television does not have to be a broadcast. My amateur radio
licence permits the transmission of television on a broadly one-to-one
basis, and broadcasting (one-to-many) is specifically prohibited.

I think that that defintion of 'television' probably still holds.  It
would presumably mean that iPlayer, and other streamed media, content
_is_ television, given that wire is specifically included in the
defintion of transmission.  I'm not a lawyer, however, and wouldn't want
to get into the debate about whether watersheds and other TV regulations
should apply online (and, if so, whether the timezone at the server or
client counts...)

Oh, I know, I know! Is it: debate the meaning of 'TV'?
