Reduced Reference Mode For RTM Solution
By Adam Schadle
Vice President, Video Clarity

V

ideo Clarity recently released a
reduced reference mode for our
RTM real-time monitoring solution.
In reduced reference mode, RTM
systems can be used to provide
continuous channel monitoring and
fault recording, based on the actual
original source programme, from
anywhere in the world.
Reduced reference mode is
intended for secondary content
distributors such as cable, IPTV,
direct broadcast, and satellite
providers that receive programmes
from content originators and deliver
them to the end viewing audience.
Unlike content originators, who
can compare the entire original
source signal to the entire processed
signal nonstop, in real-time (i.e., full
reference), content distributors do
not have access to the original

66

source signal.
With RTM's reduced reference
mode, content distributors can now
use RTM to measure their incoming
signal against representative picture
and audio source data sent from an
RTM system located at the originator
site (i.e., reduced reference), thus
allowing them to assess signal
quality and verify whether errors
were caused in transmission or from
source processing devices that are
outside their facility and control.
We've heard from customers
that they would like a way to base
ongoing quality-of-service tests on
upstream content from the originator,
so with this solution we're giving
them something they've never had
before - the ability to compare their
signal to that of geographically
removed source channels. Reduced

reference mode is specifically
targeted to the programme
originator in collaboration with
their distribution service providers
that are quality-conscious and
continuously looking for new and
innovative systems to increase their
quality of service.
When a content originator sends
a satellite feed to its secondary
distributors, an RTM system on
the content originator end sends
out data representing the original
audio and video signal via the
Internet or a dedicated network data
path. Secondary distributors can
subscribe to that data stream so that
when they receive a distributed feed
from the content originator, their
RTM unit will compare the incoming
video signal with the source data
from the original signal before any
processing takes place.
The RTM uses this comparison
to test for video and audio quality
continuously and then also records
error events such as picture
breakups, freeze-frames, and
black frames. RTM automatically
records these faults based on

user set error thresholds so that
the content distributor can take
appropriate action.
The RTM reduced reference
method is unique because it
provides the reference data from
the content source so that it can
then be used to understand the root
cause of any lower-than-expected
A/V quality event. Another unique
benefit is the number of audio
performance characteristics that
can be monitored and found, such
as audio dropout, artifact, and
low-quality differences from the
source. Moreover, the RTM reduced
reference method achieves an
accurate lip sync measurement
using only standard audio/
video signals.
RTM with reduced reference will
be demonstrated at IBC2014.
