RE: Request for external groups for TTWG

Hi Nigel,


HbbTV contains all of the major TV manufacturers who will be implementing
this spec in an embedded environment. I believe that their input could be
useful in keeping any specification relevant to that industry.

since HbbTV doesn't write specifications, but adopts them from organisations
that are already represented, what additional sort of input do you envisage
the association providing in response to the proposed deliverables?


Kind regards,

Hi Mark,


I suggest the group also talks to the HbbTV Association:

Hybrid Broadcast Broadband TV Association (HbbTV): This industry forum has
defined an HTML profile to be used on connected TVs and similar devices
which is published through ETSI. It continues to work to expand the
functionality included in their specification.

Subject: Request for external groups for TTWG


Web & TV folks, 


The Timed Text Working Group (TTWG) is asking the Web & TV IG for any
additional external groups that they should liaise with as part of their new
charter [2]. These could be national, regional or international. They could
be standards bodies or industry groups. Please reply-all to this email with
any candidate suggestions.


Here’s the current list in the draft charter:

External Groups

ISO/IEC JTC-1/SC-29 WG 11 Moving Picture Experts Group (MPEG)

This group is developing standards for coded representation of digital audio
and video, including MPEG-4.

Society of Motion Picture and Television Engineers (SMPTE)

This organization was founded to advance theory and development in the
motion imaging field. SMPTE produced extensions to TTML 1 that are part of

European Broadcasting Union (EBU)

EBU is a confederation of national broadcasting organisations, facilitate
exchange of audiovisual content. This Group has developed an XML -based
format for use in subtitling production and exchange, based on TTML 1.

Digital Entertainment Content Ecosystem (DECE)

DECE is a consortium chartered to develop standards for the digital
distribution of premium content.

 <> DVB Project: Technical Module (DVB-TM)

The DVB Project develops specifications for digital television systems,
which are turned into standards by international standards bodies such as
ETSI or CENELEC. It provides a conduit to other relevant standardisation
activities including MPEG for the purpose of meeting the objectives of the
DVB Project.

Hi Mark,


On Friday in Shenzhen I assigned an action to myself on your behalf (as
you're not on the TTWG tracker), which is at [1]. If you have any additions
to the external groups in the new draft charter [2] please could you send
them to Philippe (CCed), myself and David?





Kind regards,
