Rigoh Wenning, legal counsel W3C
dob: broad audience for this,
some people coming to find out where we are
... current solution is EME
EME spec -> http://www.w3.org/TR/encrypted-media/
dob: want to talk about legal
restrictions around DRM
... general improvement in copyright control
... typically copyright control attemps to compell a consumer
to do something different to the range of ability they would
otherwise have
... e.g want to play DVD in another country
... attempts to have copyright control which fit consumer
behaviour more closely, fit with expectations of consumers and
what they want to do with content on the web
... bucket of connected issues - privacy, accessibility
... some particularly fine points causing problems, but does
not strike to the heart of the issue of controlling copy,
access, usage
<paulc> EME outstanding bugs: http://tinyurl.com/7tfambo
dob: my area of interest - issues of user controll contorl of your own device, restrictions of what can be done on your device
Attendees: DOB, olivier, JCVerdie, paulc, Jerry, haakonb, James, So, Ddorwin, Bogdan, Noriya, jfoliot, Deborah, Rigo
dob: criminal sanction when
breaking (and witnessing, etc) DRM
... would be nice to sketch out that area
... any preference on which topic to address
jfoliot: as advocate for
accessibility, realise that in the past most DRM were looked at
a system
... was a problem for accessibility as user needed to modify
the system to address disability
<paulc> Re EME and Accessibility: see https://www.w3.org/Bugs/Public/show_bug.cgi?id=27054
jfoliot: EME is different -
mitigation in focus on just the content and not the player and
ecosystem
... on why I think w3c should continue work on this - PF group
will look at the specs through the lens of impact on people
with disabilities
... we can't stop a spec in its track, but carry a large stick,
so if something is going to introduce a lot of accessibility
issues we have a mandate to raise it
... we want to make sure anything that emerges will not clash
with non-discrimination laws
... while I understand that in principle DRM is distateful, but
if we are going to work on a tech best to work on it at W3C
deborah: we are at a point where
we can make things better
... content providers are not going to make content available
in a way that is not protected
... if we can deliver that content in a way that is standards
based, works with accessible viewer/reader, can use accessible
tools
... alternative would be proprietary and would not see
accessibility prioritised
dob: area of influence of w3c is in the wrapper
jfoliot: because of the way we
can provide support material e.g captions
... technology being moved forward in way that these can be
in-band, or in separate track and coming from 3rd party
source
... concern about that - if the media asset and captions are
encrypted with different CDM, what then?
... at least here I can ask that question
... example - we are adding requirements for deaf/blind
people
... requires screen reader - many available on the market
... for average production company they would not be able to
take proprietary solution and test with assistive tech
... standard promises interop
paulc: dropped link to bug
related to EME and accessibility, raised by TAG -> https://www.w3.org/Bugs/Public/show_bug.cgi?id=27054
... requirement to have similar accessibility as you would
without EME
... no-one has identified any concrete changes yet
dob: part of legal issues around
restrictions and limitations revolves around
access/accessibility
... ability to format-shift
... part of the challenge is that content is not available to
the rest of the interface but could be accessed (legally) and
transformed
... TAG is raising this issue but we do not have model for how
video could be transformed
paulc: if you remove EME what changes here?
dob: the fact that it would be illegal
[scribe missed conversation, technical issues with IRC client]
deborah: legal question on fair
use for right to transform for accessibility reason
... case law not yet established
dob: tension you've got is that would be perceived as a straw to suck content out
deborah: international copyright
law not yet covering this
... nothing the W3C can do right now
dob: there is something normative
here happening - discussion on using HTTPS to convey content
(for privacy)
... one of the bugs raised is that it is often necessary to
identify user
... general concern that traffic may identify user
uniquely
... suggestion that communication be encrypted
... issues around that - practicality, role of w3c in raising
and solving one set of privacy issues around DRM
paulc: similar to discussion at
IETF - discussed, answer was no
... some people believe https MUST be used, other think it
should be a SHOULD at most
<paulc> EME bug on usage of HTTPS: https://www.w3.org/Bugs/Public/show_bug.cgi?id=26332
olivier: explain that requiring https throws things like caching out of the window
paulc: that was the main argument against making TLS mandatory
mark: practical issues concerning
us is almost the opposite
... large volume of content, would have impact on
capacity
... we don't actually like people caching our content
... causes hard to debug customer problems
paulc: expect we will see this request made in other places - not just for media
ddorwin: point to next session on
privacy
... monitoring etc
rigo: there is no option of not doing it
mark: discussion of cost of flipping switch
dob: feel that there is similar
interaction between consensus (privacy) and awareness of
challenges
... want to make sure we talk about issues that are outside of
w3c
... broader copyright issue with accessibility
... problems would largely go away if legal framework was
reformed
mark: want to go back to specific
issue with DRM and privacy
... mitigation on identifiers
... discussion would not have happened if we hadn't been doing
this in w3c
rigo: do you plan to expose
rights metadata?
... everyone agreed (at workshop - date?) that it would be
good.
paulc: relationship to DRM? should probably be solved for any data
rigo: sounds like a great semantic web project
jfoliot: emergence of schema.org
somewhat solves that
... was talking with Chaals on using metadata for
accessibility
... technology is emergent, need to solve this for all data on
web
... locking mechanism for encrypted content - serving metadata
would add value
dob: closed format or DRM means
no way of deriving metadata
... so you need a system to ask
... people wanting to copy-control also want to control
metadata too
... because it may be a revenue opportinuty (e.g what's playing
on the radio)
Attendee+ MichaelGood
michael: how does EME address customer irritation?
mark: use case of content
subscription
... understanding that you do not own content
... EME would work for this use case alone
ddorwin: we are using it for
rental and purchases
... there is a difference there
... "buying" on the web is different
mark: issues when advertising does not match reality. not "getting a digital copy"
jfoliot: worked at Capital record
- through the years music did not change but carriers did
... when you buy, you buy the carrier, not the content
... consumer irritants often about player being locked
down
... putting malicious software in the player
olivier: similar feeling about EME - adding malicious software to inherently open software - until now
jfoliot: you are not going to
convince everybody - but think that we can work to fix this
perception problem
... need to do a better job at transparency / explaining the
reality of the pain points
... less of a technical problem than a marketing problem
paulc: AD BREAK - consider
attending HTML WG meeting on Friday morning
... start at 9
... triage EME bugs
ddorwin: public-restrictedmedia mailing-list where things such as fair use are being discussed
dob: do think a lot of these things are within purview of w3c - we can discuss issues of e.g accessibility and wider legal context
<paulc> See http://www.w3.org/community/restrictedmedia/ and http://lists.w3.org/Archives/Public/public-restrictedmedia/
dob: even though mostly engineering, good to have such discussions
