Harris Broadcast's<br />
Platinum IP3<br />
Multi -path, multi -frame routing is now a reality.<br />
BY KERRY WHEELES<br />
The router has long been the<br />
traffic cop of the broadcast<br />
facility, directing signals to<br />
various control rooms and<br />
destinations around the plant. But,<br />
it's become clear that traffic direction<br />
alone is insufficient to support<br />
today's ever -increasing signal volume<br />
and complexity.<br />
The usefulness of increased router<br />
capability extends well beyond the<br />
traditional call -letter station. Central -<br />
casting facilities and satellite head -<br />
ends support many more channels<br />
today compared to one decade ago,<br />
and mobile production trucks often<br />
require 512 x 512 matrices or larger.<br />
Meanwhile, facilities like sports venues<br />
and houses of worship are asking<br />
more of their routers, from increased<br />
signal capacity to tighter integration<br />
with complementary systems.<br />
Meeting these expanded signal<br />
routing and management requirements<br />
is just one reason that<br />
Harris Broadcast has introduced the<br />
Platinum IP3 router. It delivers multiformat<br />
signal routing up to 576 x<br />
1024 in a single 28RU frame, and<br />
scales to more than 2048 x 2048 in<br />
multi -frame configurations.<br />
Additionally, the router breaks new<br />
barriers for signal redundancy, on -air<br />
expandability, stability and control,<br />
while also offering the industry's first<br />
path toward true network convergence<br />
within the router.<br />
From there to here<br />
High- density routing, integrated<br />
processing, reduced power consumption<br />
and smaller rack -space requirements<br />
remain significant capabilities<br />
in the IP3 design as an extension of<br />
the established Platinum architecture.<br />
Notably, the original Platinum's<br />
inclusion of a dual -path routing architecture<br />
was a big technical stride,<br />
enabling completely independent<br />
audio and video paths for every slot<br />
within the frame. This enables a completely<br />
embedded routing infrastructure<br />
without sacrificing matrix size.<br />
The IP3 evolves this concept with<br />
the industry's first triple -path architecture.<br />
The third, separate path is designed<br />
to accommodate data -centric<br />
elements that might include program -<br />
associated metadata, graphical elements<br />
or pure IP signals. The ability<br />
r><br />
The IP3's technologies introduce faster<br />
processing and increased bandwidth to<br />
support triple -path architecture.<br />
to support separate video, audio and<br />
data paths is what makes the IP3 the<br />
first router architecture that promises<br />
true network convergence as the industry<br />
moves from pure baseband to<br />
a hybrid infrastructure.<br />
Unique architecture<br />
The road toward creating the industry's<br />
largest -capacity router and<br />
first triple -path routing architecture<br />
begins with the product's unique design<br />
characteristics.<br />
The IP3's enabling technologies<br />
introduce faster processing and increased<br />
bandwidth to support the<br />
triple -path architecture, reducing<br />
hardware and accommodating more<br />
signals. The design also greatly simplifies<br />
wiring and integration and<br />
eliminates the need to take stations<br />
off the air while scaling into multiple<br />
frame systems.<br />
Large routing systems involve multiple<br />
separate frames due to physical<br />
limitations for signal capacity.<br />
Traditionally, this requires external<br />
distribution amplifiers to support<br />
signal expansion to multiple frames.<br />
To expand into additional frames, the<br />
user must unwire each input from the<br />
first frame and run it through a distribution<br />
amplifier to the original and<br />
new frame or frames. Further adding<br />
to the complexity, outputs from two<br />
frames, each with unique sets of inputs,<br />
require a secondary switching<br />
matrix to avoid "blocking" signals.<br />
The expansion process requires the<br />
user to "break" the signal upon adding<br />
another component - thus taking<br />
the station off air.<br />
The IP3 design builds distribution<br />
amplifiers into the routing frame, employing<br />
a single -wire connection to<br />
bridge each input module to the next<br />
frame - without breaking signals<br />
from the first frame. Additionally, an<br />
intelligent output module design ensures<br />
that each new input, regardless<br />
of which frame it enters, is available<br />
to all router destinations.<br />
This architecture provides seamless<br />
expansion between multiple frames,<br />
reducing wires and without taking<br />
the station off air. Furthermore, the<br />
common architecture preserves the<br />
initial investment - and ensures no<br />
limitations for future expansion.<br />
