IABM Report on IEC TC100
2016-01-27
The IABM compiles these reports
for its members every 2 months.
The IABM participates in TC100
through committee EPL/100 of
the UK National Body, BSI.
Structure of TC100 into Technical Areas:
TA 1:
Terminals for audio, video and data services and content
TA 2:
Colour measurement and management
TA 4:
Digital system interfaces and protocols
TA 5:
Cable networks for television signals, sound signals and interactive services
TA 6:
Storage media, storage data structures, storage systems and equipment
TA 8:
Multimedia home systems and applications for end-user network
TA 9:
[Disbanded]
TA 10: Multimedia e-publishing and e-book technologies
TA 11: Quality for audio, video and multimedia systems
TA 12: AV energy efficiency and smart grid applications
TA 13: Environmental aspects in the field of audio, video and ICT equipment
TA 14: Interfaces and Methods of Measurement for Personal Computing Equipment
TA15: Wireless Power Transfer (WPT)
TA16: Active Assisted Living (AAL), accessibility and user interfaces
This committee also monitors
the European Cenelec committee
TC100X which shadows the whole
of TC100. However, as the
Cenelec activities are often
limited to the adoption of IEC
standards, the IABM does not
cover their documents in depth
except when they produce
“Native” documents on subjects
of interest. Topics where Cenelec is developing their own documents include Energy Efficiency and Active Assisted
Living.
Documents Issued from 2015-10-11 to 2016-01-27
There were 53 documents supplied [Ref range: EPL/100_15_0166 to EPL/100_16_0024, plus some external
documents over this period]. Many documents are administrative or they cover technologies that are of no interest
to IABM members; however, for completeness, the full list is available below. In that table, brief IABM notes have
been added, where relevant or interesting.
Your IABM representative has access to all of these TC100, Cenelec and BSI documents and can support member
enquiries on them – please contact paul.treleaven@theiabm.org.
Documents relevant to Broadcast Products and Services
IEC 60958: Digital Audio Interface – New work to support Multichannel audio
We introduced this proposal in the last report and the only change this time is that the project has been
approved and both Dolby and DTS have signed up to the project team. The work is useful, and these
enhancements could easily migrate to the professional interface, AES3, in the future.
Even if it does not, equipment supporting the commercial interface and this extension to it is certain to be in
use in broadcast facilities.
This project specifies
enhancements to the consumer
digital audio interface:
- carriage of multichannel audio,
by using high sample rates and
creating a sequence of audio
frames to carry the required
channels; the existing interface
only allows a 2-channel sequence.
- carriage of higher bit-depths. A
scheme being considered is shown
in the slide (right).
It is somewhat ironic that work in
the AES to do something very
similar for the professional AES3
interface has stalled because
there were disparate views about
whether the signal should be compatible with existing interfaces, to take advantage of existing AES3
infrastructure, or deliberately “break” AES3 to ensure that existing receivers don’t try to decode the sequence
as 2-channel audio.
New work on UHD Terminology
A draft document has been submitted together with the call for experts to participate in the project. The
current draft structure is confused, some of the terms also.
Revision to the Cable Television suite of documents (IEC 60728)
The purpose of this revision to Part 13-1 is the precise description of the FTTH (Fibre to the home) system for
expanding broadband broadcast signal transmission from CATV services only, towards CATV plus Broadcast
Satellite plus Communication satellite services and additionally to various other signals such as data services.
General Channel Assignment of Multichannel Audio - IEC 62574
The review has decided that this standard will be revised and a project team has been assembled. The main
changes will be the addition of the sound source position information and additional channel assignments.
There is work in SMPTE related to channel assignments, so this revision may be useful with that work.
