Case
Study:
Remote Video Editing
& Production
During the
2004 Summer Olympic Games in
Athens Greece, the athletes
weren’t the only ones
setting records. Radio-Canada/Canadian
Broadcasting Corporation (CBC)
in Montreal Quebec also achieved
a milestone. Instead of moving
its video editing and production
operation to Athens, CBC kept
it in Montreal where CBC staff
edited live video feeds, produced
the final version and broadcast
it throughout Canada.
Compared to
the traditional method of moving
equipment, people and temporary
facilities on-site for major
televised events like the Olympics,
keeping video production at
the home location saves a significant
amount of time and money.
Now, Radio-Canada
is preparing for the Beijing
Olympic Games in 2008, where,
once again, they will conduct
video editing and production
half a world away from the live
event. As such, CBC must identify
the impact of long haul delay
on its video applications. They
expect transmission time from
Beijing to Montreal to be as
long as 300 ms in each direction,
significantly higher than the
60 ms Athens to Montreal transmission
time.
From China
to Canada, video traffic will
be carried on a SONET OC-3 link
(155 Mbps). On this network,
CBC will build ATM Permanent
Virtual Circuits (PVC's) of
various sizes, upon which they
need to simulate propagation
delays. CBC chose the Anue Network
Emulator for latency testing in order to provide
"dialable latency measurements,"
of up to 500 ms. (At OC-3 data
rates, Anue’s M Series
Emulator enables up to 4 seconds
of delay, which more than met
these requirements). CBC also
needed a product that has multiple
interfaces so that both GigE
and SONET links could be emulated
with the same hardware platform.
Today, Broadcast
Engineers at CBC are testing
their applications on a simulated
WAN using Anue’s MSDG312,
SONET/SDH OC3/STM1 and OC12/STM4
Signal Delay Emulator. With
the help of the Anue Tester,
they will be able to ensure
with confidence that their process
of editing and producing live
video received from remote locations
works as expected.
