ERICSSON
Helps
PSSI
Take
NASCAR
From
the
Track
to
the
Studio
in
HD
13
April
2010
NASCAR
Media
Group
(NMG)
provides
multiple
streams
of
HD
content
captured
live
at
the
races
for
viewing
by
its
75
million
loyal
fans
throughout
the
world.
To
accomplish
this,
PSSI
Global
Services
LLC,
(PSSI),
a
leading
provider
of
mobile
satellite
transmission,
production
and
streaming
services,
transports
various
HD
sources
over
satellite
to
NMG’s
new
studio
facilities
in
Charlotte,
NC.
Once
there,
those
sources
are
switched
live
for
distribution
to
DTV
services
providers.
Ericsson
provided
PSSI
with
a
solution
featuring
its
MPEG-4
AVC
HD
encoders
and
receivers
to
support
NMG
and
PSSI’s
other
clients.
From
track
to
studio,
the
solution
allows
HD
content
to
be
captured
and
transported
using
techniques
to
maximize
the
available
bandwidth
usage
and
provide
the
highest
possible
picture
quality.
This
allows
production
teams
to
prepare
and
edit
from
pristine
quality
footage
to
create
the
best
viewing
experience
for
fans
viewing
at
home.
"The
ongoing
success
of
this
project
depends
on
the
Ericsson
solution.
The
company
has
proven
to
be a
reliable
business
partner
that
we
can
trust,"
said
Brian
Nelles,
senior
vice
president,
PSSI
Global
Services.
"The
technical
team
is
exceptionally
knowledgeable
and
provided
us
with
a
solution
that
yields
a
flawless
video
transmission."
"HDTV
is
now
considered
an
essential
part
of
the
television
viewing
experience.
The
number
of
programming
options
continues
to
grow
to
meet
the
ever
increasing
viewer
appetite,"
said
Matthew
Goldman,
head
of
compression
technology
at
Ericsson.
"Having
companies
like
PSSI
place
their
trust
in
us
is
an
honor
that
drives
us
to
keep
creating
the
best
solutions
for
the
market."
The
NASCAR
project
requires
the
most
bit
rate
efficient
MPEG-4
AVC
encoding
in
order
to
send
six
paths
of
HD
material
along
with
forty
eight
channels
of
team
communications
audio
down
one
36
MHz
satellite
transponder.
The
Ericsson
EN8090
AVC
encoders
perform
this
task
at
bit
rates
ranging
from
15.50
Mbps
to
as
low
as
7.00
Mbps
for
key
signals,
providing
PSSI
with
highly
efficient
bandwidth
usage
while
still
delivering
the
highest
possible
picture
quality.
"The
timing
of
the
sources
arriving
to
the
switcher
in
Charlotte
at
the
same
time
for
live
switching
is
mandatory.
This
was
easily
handled
on
the
Ericsson
encoders
by
placing
them
in a
variable
seamless
delay
mode,"
added
Nelles.
Reception
of
these
HD
sources
is
handled
with
Ericsson
RX1290
decoders.
A
second
transmission
pathway
is
used
for
various
clients
including
The
SPEED
Channel,
and
finally
a
third
pathway
is
utilized
to
carry
a
five
channel
MCPC
feed
of
HD
video
for
DIRECTV
Hot
Pass.
These
other
services
are
encoded
with
Ericsson
E5788
MPEG-2
HD
encoders.
