New
Carrier ID Technology Approved For
Standardisation
7 March 2013
The Satellite
Interference Reduction Group (IRG) today
announced that the DVB Carrier ID
(DVB-CID) specification, supported by
IRG and its members, has been approved
by the DVB Steering Board on 28th February
2013. The specification will now be
submitted to the European
Telecommunications Standards Institute
(ETSI) for formal standardization. The
DVB-CID specification is available for
downloading on the DVB website1.
The new technology
is based on a proposal by Comtech EF
Data and became a DVB specification
supported by a wide group of
manufacturers including Advantech
Wireless, Ericsson, Gilat, Newtec, and
iDirect, following a meeting instigated
by IRG at the 2011 IBC. Manufacturers,
such as Newtec and Comtech, are
implementing the new technology into
their modem products, starting with the
Comtech EF Data DM240XR and
the Newtec M6100 modulator.
Products implementing the new DVB-CID
will be announced at CABSAT.
The new spread
spectrum Carrier ID standard adds a low
power spread spectrum carrier underneath
the host carrier it will identify. This
means that the correct transmission
doesn’t need to be interrupted to
identify the interfering carrier,
enabling the operator to drastically
minimize the effect on the correct user.
“We are delighted
that this new DVB specification has been
approved,” commented Martin Coleman,
Executive Director, the Satellite
Interference Reduction Group. “We are
now aiming to ensure this new standard
is integrated across satellite equipment
for all SCPC (Video & Data) transmission
types, in time for a number of high
profile sporting events in 2014.”
The CID carrier has
no real impact on the host carrier and
typically adds less than 0.1dB of noise
energy to the host carrier. In dual
illumination situations, multiple
over-lapping CIDs can be decoded at the
same time, allowing efficient
resolution.
“This new
specification will help the industry to
drastically reduce the time to resolve
day-to-day satellite interference,”
commented Roger Franklin, CEO, Crystal
Solutions and Chairman of the CID
Working Group, IRG. “We are pleased to
have worked with the industry to
formalise this important specification.”
