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 />
