Cost recovery does not apply to distribution through the DTG.

It would appear to be perverse to apply any cost recovery to a document 
distributed to the public over the internet.


Development cost estimate:  Twenty four point seven million pounds over 
five years (24.7 million).


I suspect cost recovery, of operational and development, costs would 
apply to content.


This would appear to be zero for the BBC, as iplayer will have zero 
usage cost (the BBC is publicly funded). It may involve advertising for 
other free-to-air broadcasters.


The purpose of the cost recovery clause appears to be, to prevent 
members from profiting from Canvas content distribution, while avoiding 
a loss.

Earlier there was mention made of a 'cost recovery'.

The incremental costs of publishing am individual text document are of 
course close to zero. (arguably exactly zero, possibly, for the case of 
the BBC)


However - would 'cost recovery' also include the recovery of the cost of 
development of the platform?

The BBC has to be careful of it's legal obligations.

I think the context has changed.

The BBC was under pressure to lock down the specification to ensure all
TV receiving equipment implemented content protection. This encountered
unanticipated legal complications, so the pressure for lock down is removed.

The BBC can therefore be much more 'open' with the core specification.
(and even the UX).


the fact is, the BBC considers the DTG to be a non-partisan
organisation, and so (despite the exorbitant costs of membership) very
likely considers it to be a satisfactory vehicle as far as
'non-discriminatory' is concerned.



As project Canvas already releases information (and has provided a 
schedule for further releases) to the industry for peer-review, why the 
requirement to publish the specification within 20 days of approval.


http://www.projectcanvas.info/index.cfm/news/?mode=alias&alias=Project-Canvas-releases-further-information-to-industry-on-technical-specifications


Peer review is different from publishing the interim or final standards. 
The D-Book is only available to full members (of the DTG).


http://www.dtg.org.uk/publications/books.html


an entirely artificial cost barrier is not generally deemed to be
'discriminating' by the BBC, even if in real terms it actually is.


See sections 4.62, 4.72 and 4.74
http://www.bbc.co.uk/bbctrust/assets/files/pdf/our_work/canvas/canvas_conclusions.pdf

I think this is sufficient to require the specification to be public.
Mo disagrees, we will know for certain in less than 20 days time.

I don't think the BBC agrees with you, though.


I may be reading too much into sections: 4.62, 4.72 and 4.74.

There is no (longer) any method of enforcing the standard (No NDA)

Unsure. depends if there's room in the UX for it, and it doesn't

Keep reading.

Bear in mind that it's a set of *conditions* as applied to the
existing proposal, which isn't spelled out in its entirety in that
document. You need to read both together.

The proposal says "the Canvas UX is mandated for access to the content"

The conditions document says (see 4.38 and on) "nothing to see here, carry on".

The Approval Document _specifically_ covers, in several places, the
mandated UX requirement.

(Admittedly, it covers it by way of "yes, we're aware there are lots
of objections to this, but we think it's fine. go take a hike.", but
the point stands: the mandated UX is part of the approval).

well, you're muddling content provider and consumer conditions, but
essentially, yes: the mandated UX is bonkers. there are better ways to
achieve the same goals (which weren't particularly well-stated at any
stage of the process, incidentally).

the mandated UX was my primary objection to Canvas (and indeed, apart
from the shockingly bad consultation process, if it weren't an issue,
I probably wouldn't have objected - repeatedly - in the first place).

No, this is what I'd expect the BBC to do.

It serves the public when market-based squabbles over alternative technological
platforms don't happen, and everyone just gets on with innovating atop a
good-enough platform, rather than frittering away consumers' time and money
by playing platform argy-bargy.

Of course, this makes other broadcaster's jobs easier, but that's a good
thing; the harder it is for them to develop something, the more they'll
want to control what they developed.  Relieving them of that burden is
to everyone's benefit, not just theirs.


It's unlikely such a wide group of companies would ever reach a consensus 
otherwise without the BBC.


Exactly.  Markets aren't very good at arriving at a new platform from
a standing start, largely due to company boards treating technological
platforms as a strategic asset when they get the chance.

Hence, HD-DVD versus Blu-Ray, VHS versus Betamax, or, for those old
enough to remember, AC mains versus DC mains, or broad gauge versus
standard gauge.

As Joel Birnbaum (former HP Labs director) noted: standardizing the
mains socket enables enormous innovations on either side of it, rather
than constant arguing about what shape the pins should be.

If the BBC can help take the debate about a platform's 'shape' off the table,
it allows everyone to concentrate on building stuff on that platform,
which can only be a service to the public.

As a user I want just a single garden, I don't want to have vary bits of
software with varying levels of brokenness for my choice of platforms. A
single platform is good for the user it allows everyone to build to a
single standard.

It also potentially allows new content providers into the same
distribution space without the problem of finding transmission frequencies.

So bailing out is not the way I look at it personally. The cost of
building the platform in comparison to say electricity & overheads to
drive transmitters is minimal, based on a back of the envelope
calculation on figures from a few years ago.

Does anyone else see this as the BBC effectively "bailing out" other 
broadcasters by providing a common platform backed with licence fee funded 
content and development?

It's unlikely such a wide group of companies would ever reach a consensus 
otherwise without the BBC. Anything similar would probably take many more years 
to develop because of all the wrangling or even be homebrew or developed by an 
outsider (e.g. Boxee). The DRM and payment model is standardised and presumably 
reasonably secure which reduces the duplicate work required by other 
broadcasters and makes the user-experience better (one payment gateway, one box 
etc.).

Does the requirement to publish the technical specifications within the
next 20 days mean they will be freely available to anyone who wants them,
or would that mean they would only be available to members of the DTG?
