David,

As we have not actually seen the real Ofcom response yet, I don't know the
answers to your questions.  But asking the legal position was my one and
only response to the consultation, so it will be interesting to hear it.

If I had the resources I would launch a judicial review, as this is
an appalling situation for Auntie.

To expand my argument (as you have seen my previous post).

It is a matter of principle not expediency.

They are constructing the Infrastructure of Control, and the BBC are 
party to this. Such control which is never in the public interest.


If, as Mo pointed out, the guidelines say the 'copy never flag' should 
never be used. Then why does the copy never flag exist ?


In fact why is the whole infrastructure, been made more complex, brittle 
and expensive ?


We need to reject DRM in principle. The fact that it is ineffective in 
practice, is not a reason to tolerate this.


At the risk of infringing the Manic Street Preachers copyright:

If you tolerate this, then your children will be next ...

Only they won't wait for your children ...

Of course my use of the Manic Street Preachers lyrics is fair use, but 
the use of even a single frame of a protected HD content, fair use (or 
fair dealing) is prohibited by technology, not the law (or and the law 
as it is protected by technical measures).


Pastor Martin Niemöller is less likely to issue an extra judicial take 
down notice, especially if I change the text: first they came for the 
pirates...


The use of a single frame of protected HD doesn't breach the law, but 
still subject to technological measures and extra judicial enforcement. 
The circumvention of technological measures, to enjoy to copyright 
exceptions under the law, is in breach of the EU Copyright Directive.


The reality is everyone breaches copyright, all the time, and copyright 
is subject to fair use (fair dealing) ...


You make think this is exaggerated, but once you concede the principle, 
  and create the infrastructure, Intellectual Property owners will try 
and extend their control.  See the secret ACTA treaty from which the 
public are excluded, and is even outside purview of the World Trade 
Organisation, and which did not originally address Intellectual 
Property. etc.


Even GM crops are just another Intellectual Property land grab, dressed 
up as in the Public Interest.


Intellectual Property, an idea that was never justified, never served 
the purpose stated in the US constitution, and whose time has passed !

 The BBC has made its position quite clear on the blog - not once but 
 several times. We have been straight about it as you can see from 
 these blog posts, not just recently but as far back as April last year

 (see Danielle Nagler's post in the list below) - so the idea that we 
 didn't want to talk about this is false:

well, yes. the *position* was very clear. the facts - that is, what was
being proposed and the nitty-gritty of how it would actually affect
people - weren't, as evidenced by the many questions which went
unanswered in the blog comments.

Tom Watson's blog post contained inaccuracies because he was
interpreting a very technical industry document without background
knowledge - which was what everybody else (myself included) had to do in
order to figure out what it was that was actually being proposed (how
else are people supposed to know what they're dealing with?)

the _position_ took priority over the facts. the BBC was very effective
at communicating the position. it was abysmal at communicating the
facts. the closest it came was Danielle's post back in April last year
(which I linked to earlier in this thread - I was very aware of it!),
and even that was rather heavy on the PR, and took some flak at the time
for it.

 I have worked hard to get the BBC to engage with you and in my view 
 bearing in mind the obvious sensitivities we have done this well. Even

 I though we couldn't publish your blog post I spent time trying to get

 it published in other places, encouraged you to do so and I was 
 pleased when it was.


Don't get me wrong, I do very much appreciate your efforts - please
don't take this as a personal criticism, because it's not, at all - in
no small part because it's not *your* job to translate engineering terms
into the actual effects. I'm not sure what the sensitivities are - does
the public not have a right to make an informed judgement given the
facts of it?

 And I'm saddened that you use the word disgraceful in your email 
 below. I believe the BBC has communicated this as well as we can.

I'm sorry you're saddened, but believe me, the BBC (not you singular),
could have done a lot better better. Communication on this was shoddy
and haphazard, it - with the exception of Danielle's post - reeked of
damage-limitation, missed out half of the stuff that people would
naturally want to know, and you weren't able to find out the answer to.
In fact, you had asked some of same questions, because you didn't know
the answer either. I know for a fact, though, that lots of the people
within the BBC who were involved in creating this whole thing would have
known the answers, because if you're an expert in DVB, it's actually
pretty basic stuff! (don't forget, this had already been implemented
once already, and the BBC, via the DTG and DTLA, were talking to
receiver manufacturers to ensure they were doing the right thing).

so, to be brutally honest, if there's something you couldn't be more
wrong about in this whole affair, it's this. the BBC wasn't particularly
honest - it didn't lie, but it was a very very long way away from the
whole truth - and I think it's unfortunate that you've been taken along
for the ride. I think *you*, not to mention everybody else, deserve
better than that, even if we ultimately disagree about whether the
actual proposal is a good or a bad thing.

Section 2.18

Ofcom is mindful that it does not have a power to include conditions in 
the Multiplex B licence relating to content management per se. Ofcom may 
only include those conditions specified in the 1996 Act and those it 
considers appropriate, taking into account its duties in the 
Broadcasting Act 1990, the 1996 Act and the 2003 Act.


None of those duties relates to the ability of viewers to deal with 
content once broadcast. Nor do they relate to the markets for receivers. 
In those circumstances, Ofcom could not impose a condition requiring 
content management nor could it expressly restrict the ability of a 
multiplex operator to implement content management.


Nor can Ofcom explicitly give consent, as it is clearly ouside it remit, 
especially when such consent would breach the EU Law, that Public 
Service Television has to be broadcast unencrypted.


There appears to be no evidence that Ofcom or the BBC are acting within 
the law.

[backstage] Freeview HD Question

2010-06-16 Thread Stuart Clark
Does anyone have details on how the process for getting the necessary
details to officially obtain the tables/information to decode the encoded
EPG data?

I have seen somewhere that the stipulation was that this should be
royalty free, but that doesn't exclude administration costs, and
obviously there are likely to be restrictions imposed upon subsequent
recording, etc by virtue of the contract the licensee has to agree to.

Is any of this known or publicly available?

[I know such information doesn't help for open source projects, but it
would be interesting to know the level of the monetary/contractual bar to
people wanting to do things officially, and what effect doing so has on
their products]

If they did it right then it would be a help (of sorts) to Open Source
projects and everybody would be happy. All that's needed is a website
where there's a form that includes an all import I agree to the terms

This would be pretty much identical to how a lot of Open Source

Equally depending on any costs/restrictions a company could offer a closed
binary plugin for some OS projects [depending on licensing restrictions on
plugins] which can be sold to the public - for example how some non-open
audio/video codecs are.

But that of course would only work if the costs were reasonable (it isn't
going to work if it would cost £1 million a year as the market for OS
sales would never cover that cost) and the restrictions are compatible (if
the license for the tables/info has requirements which would be impossible
to implement as a plugin for video player X)

Presumably those are more likely to be created/sponsored by a company (ie
the hardware manufacturer) who could go along the closed/open mix method
(if the OS software allowed it and the BBC license allowed it too)

The costs would be interesting though - for a small company interested in
starting in the market a few hundred pounds would be fine (but that would
probably exclude most home users), but tens of thousands would be a much
bigger problem.

I doubt it would matter much with embedded systems. I can think of three cases -

1) The company involved doesn't release the source, even though
they're obligated to (which is still worryingly common) - then they
just include the tables in their product (so no different from a
closed source system)

2) The company release their OS components, but the 'secret sauce' is
a closed source app - again, they just include the include the tables
in their product like a closed source system.

3) The company's embedded system is entirely open source - on the
device they include the tables, in the source tarball they don't but
include instructions along the lines of Download the tables from the
the BBC website and unzip them into /src/resources/epg-tables.

actually, that's not a bad approach with respect to the tables
themselves: /tmp/eit-decoder.sock

the snag is in what conditions the tables are licensed under - because
we're not just talking about a license for the tables themselves, but
conditions which apply to the whole device which must be adhered to in
order to use those tables (enforceable or not, I know not - but who
wants to take the risk?)

if they say no user-modification of the device shall be permitted,
but the license for the software includes anti-TiVoisation clauses,
then that's a problem - irrespective of whether the tables or the
decoder app are open or closed.

without seeing what the terms say in full, it's impossible to know
whether there's a workable solution. there are lots of this might be
okay if you work around it in *this* manner or this might cause
serious legal problems, but there are very few sureties (except for
the fact that somebody has to do the legwork to figure all of this
stuff out, which comes at a nonzero cost).

 If they did it right then it would be a help (of sorts) to Open Source
 projects and everybody would be happy. All that's needed is a website
 where there's a form that includes an all import I agree to the terms
 and conditions tick box and then everyone who uses an open source
 project could individually get their own tables.

 This would be pretty much identical to how a lot of Open Source
 projects that connect to Web Services that need a developer API key
 work.


That's an interesting point, and it's possible that something like that
could be done.

But the BBC would require as part of the download agreement that you had
appropriate content management on the device, wouldn't they? And that's the
part that is really a problem - forcing content management into the
ecosystem.

I would be very surprised if that wasn't part of the T  C's, but then
it's not much different from how Last.fm's T  C's state that you
won't use their API to write software that downloads their radio
streams.

While there's nothing really stopping people from violating the TCs
that they agreed to, there's also little to stop people from illicitly
cracking the system anyway. If there's a legal way to get the tables
then at least there's a way for people to play along with the system
as opposed to having to go down the illicit route from the get go.

 It's only on the EPG anyway, even Windows Media Centre will bypass
it, as it uses the DigiGuide one.  Or record the whole audio-video
stream and use an edit package.  Or pause/record the old fashioned way.


 Deviation from the main topic - sorry - but I don't think WMC uses
DigiGuide data (at least - it never used to). BDS was (and still is?)
the original supplier to MS.
 
 Oh, it was Microsoft who told me that they sourced all their data from
there.  Either way, it doesn't use the broadcast guide, the one with the
protection.
 
WMC started using the broadcast EPG with Freeview when the Vista 'TV
pack' update came out. Using a live EPG was a requirement of getting the
Freeview+ certification IIRC. 

On DSAT I'm fairly sure it follows the EIT now/next info but does not
populate the full guide with it, as it usually records programmes
correctly that have started late/overrun due to sports events.

Re: [backstage] Freeview HD Question

2010-06-16 Thread Alex Cockell
Now, if the bbc would consider rolling out a library like this under the 
LGPL 

One of these for the epg, but release the source under a bsd-like licence to 
distro suppliers so they can compile to tgt architectures and release through 
Partner-type repos...

Use that as a proof of concept for a Universal iPlayer Plugin for Totem, VLC, 
native players...

Well, I can dream, can't I...
