Broadcasting Without Boundaries
Van Duke, Director of USA Operations,
PlayBox Neo, surveys the expanding
frontier of CDN-based delivery...

T

he broadcast industry
has its roots firmly
entrenched
in
wired
telephony. Back in the
late 1880s, slightly before
my time, the early model
was
audio
programme
distribution via conventional
telephone lines to paying
subscribers.
The
core
technology was developed
Alexander
Graham
Bell
whose American Telephone
& Telegraph Company grew
into one of the world's most
powerful telco service providers.
Telephone-based subscription music
services sprang up in various countries
and everything looked rosy until the
invention of what would nowadays
be termed disruptive technology:
radio. This was a one-to-many form
of communication rather than the
essentially one-to-one technique of
wired telephony. But going wireless
worked so well that it even threatened
to disrupt the newspaper industry.
Telco-based broadcasting revived
in later decades with the introduction
of cable television services, carried
along wide-bandwidth copper cable.
But the biggest disrupter of all was
satellite broadcasting, initially to large
downlink antennas at the cable TV
head-ends and eventually via much
smaller antennas direct to home. When
digital technology became affordable,
the number of channels available via
terrestrial as well as satellite-based
became very large indeed.

were the national TV channels
extending their reach to expatriate
viewers far beyond their terrestrial
or satellite footprints. They were
soon joined by national mainstream
broadcasters using computer delivery
networks, CDNs, to accommodate
'red button' side channels: temporary
TV channels available as opt-outs to
supplement major sports events for
example. These typically allow viewers
to select their preferred camera angle
or view a minority-interest event
taking place in parallel with a
primary event. Side channels
can of course be delivered via
auxiliary satellite or terrestrial
digital channels but become
much more cost-efficient
using CDNs.

devices. Leasing CDN capacity is an
added overhead for broadcasters who
are already paying for terrestrial and/
or satellite delivery media but the
advantages are substantial:
channel
managers
can
now obtain and compare
programme viewing statistics
much
more
accurately
than before and use this
information to guide their
content planning.
Mainstream Delivery
via CDN
Using CDNs as a primary
broadcast delivery route
rather than merely as a sidechannel or catch supplement
is not a new idea. It has been around
for years. CDN-based delivery is
far cheaper than leasing space on
a satellite transponder or digital
terrestrial multiplex. This has made
the Internet a logical proving ground
where new-startup channels can prove
their worth before progressing to the
traditional broadcast mainstream. The
Internet has now reached a high level
of maturity, supporting successful
video-on-demand
services
with
increasingly large subscriber bases.

from a single channel transmitting in
one language up to a full scale multichannel network for viewers across
many language areas and time zones.
Figure 1 shows the system being used
to handle playout of 30 high definition
channels at Florida-based broadcast
media services provider Olympusat.
Figure 2 illustrates the general
workflow for a single channel of SDI/IP
playout. Content scheduling, promos,
commercials, graphics preparation,
subtitling and billing can all be handled
within a single server under fully
automated control while retaining the
freedom to insert live content after
any currently airing file or, for a bigbreaking story, to switch instantly to
live pass-through.
Software Solution
PlayBox Neo's Cloud2TV takes
playout up to the next level in terms of
new-start-up flexibility. Fast and easy
to deploy, it gives network operators
the freedom to scale their activities
with unprecedented precision while
side-stepping the capital cost of
holding reserve equipment on standby.
Cloud2TV is also the perfect solution
for any channel manager seeking
the security of a disaster-recovery
centre without the rental
and staffing costs entailed
in equipping and operating
an off-site studio. Figure
