World Cup, which peaked at more than
1 million unique users and
560,000
concurrent users. Through the use of

Rai Net

Utilizes

Microsoft Silverlight and IIS Smooth
Streaming for FIFA World Cup and
N
ew Replay TV
S
ervice


Recently
Rai Net

launched two new important services:

-

2010 FIFA World Cup
: Live
s
treaming a
nd
video
-
on
-
demand
(VOD)

content from
2010
FIFA World Cup on
Rai Sport

and
Rai.tv

portal

-

RAI REPLAY
: Last
seven

days of
catch
-
up TV

from
three

main
Rai TV

channels

During the
2010

FIFA World Cup
,

Rai Net
utilized

Microsoft Silverlight

and
Internet
Information Services (IIS) Smooth Streaming

to deliver live and on
-
demand HD streaming from this event on
its
Rai Sport and Rai.tv portals.

Below are some pictures from the Rai Sport website dedicated to this event:






During the events,
l
ive
s
treaming
reached a peak of more than 1 million
unique users and up to 560
,
000 concurrent users
.

Over 30 days, the
Rai
p
ortal
reach
ed

an average of more than

20 mil
l
ion page views and 250
,
000 unique
users
per day.

The Rai.tv player is based on the
Silverlight Media Framework

and permits
users to select different camera views of the match during live events. The
player also offers a
h
ighlights menu where the editors from Rai Net can
immediately publish highlight video clips during the match,
utilizing
the
Silverlight
Rough Cut Editor

and
Composite Manifest

and using an
architecture similar to the one implemented for the
2010 Winter Olympics in
Vancouver, B.C.

Utilizing

the digital video recorder (DVR) capabilities of Smooth Streaming, Rai
Net republished the content as video on

demand (VOD) immediately at the
end of the live event, together with the highlights created during the event.


U
sers
cou
ld
replay the whole event in VOD streaming and navigate
immediately to the most important parts of the match.

The Silverlight Rough Cut Editor (RCE) enabled rapid, light
-
touch editing of IIS
Smooth Streaming video content without the need for re
-
encoding.
By using
the RCE during live streaming, within seconds an editor could mark in and
mark out the clips needed. Once marked, the clips were available for
publishing immediately during or after the event. RCE permits an operator to
use the “mark in
/
mark out”
edits acquired from an editor to produce a
Composite Manifest. The
C
omposite
M
anifest combines clips coming from
one or more client manifests into a single edited video.

Below
is
an image of the application that the operator use
s

to mark in
and

mark out edits
.


When the
Smooth Streaming Media Element
, part of the
IIS Smoo
th
Streaming Client

used in the
Silverlight Media Framework
, uses a composite
manifest as its source, it plays the video/audio content as a single stream. The
user can fast
-
forward or rewind across all the segments and
navigate to

any
points in the stream.

Timeline markers can be added to include other
information in the stream.

During the
2010
FIFA World Cup, Rai Net
also utilized
IIS Media Services 4
.0

Beta 1 integrated media platform features to stream the live event to
iPad

users. The forthcoming version of IIS Media Services will permit
use of

a single
back
-
end infrastructure to stream to PC, Mac,
iPhone
, iPad and
Windows
Phone 7

devices. In fact, starting with the H.264 video content received from
encoders in the fragmente
d MP4 format used for Smooth Streaming, IIS

M
edia
S
ervices
4
.0

is able to
transmux

(repackage from one file format to
another) on the fly to the
Apple HTTP Live Adaptive Streaming

(
m3u8
) format
compatible with iPhone and iPad.
T
o distribute the content, Ra
i Net
us
ed an
HTTP edge
content delivery network

that pulled from IIS

M

S

origin servers and distributed the content to both Silverlight and iPad users:





Another important service was recently released from Rai Net: Replay TV
service. Repl
ay TV on the Rai.tv website repurposes the
p
ast
seven

days of the
three main Rai channels as VOD content delivered with Silverlight and IIS
Smooth Streaming. In addition, 24
x
7 live streaming
is

simulcast from the same
three channels and also delivered usin
g Silverlight and Smooth Streaming.
