MediaStar 799 IP Re-Caster Installation Guide
The MediaStar 799 IP Re-Caster allows
IP TV channels to be transmitted
between remote sites, using a regular
internet connection or on a quality
controlled corporate VPN link. It can
also perform multicast and unicast
stream conversion and replication on a
LAN.
A pair of 799 IP Re-
Caster ‘Blades’ can
simultaneously transfer up to 25 SD or 15 HD
TV channels across an internet connection, or
up to 70 SD or 35 HD channels across a
corporate VPN. A single Re-Caster can transfer
TV channels to multiple sites.
The 799 IP Re-
Caster is a ‘Blade’ device that fits
into a MediaStar 770 rack or a 769 single
‘Blade’ chassis. It has on
-board web pages that
allow it to be easily configured.
A complete remote site IP headend can be
provided with just a single 799 IP Re-Caster in a
769 single ‘Blade’ chassis (subject to the
number of TV channels required).
The Re-Caster takes source-specific multicast
streams and converts them to unicast streams
for transition across a VPN. When the unicast
stream reaches the Re-Caster on the remote
side of the VPN link, it converts it back to a
multicast stream for LAN transmission to
settops and PC/MAC clients which show the TV
pictures.
What’s
in the box:
•
799 IP Re-Caster Blade
•
CAT5 Patch cable
When only a regular internet connection is
available between sites or the VPN does not have
good Quality of Service (QoS), the Re-Caster can
be configured to use Secure Reliable Transport
(SRT) protocol to transfer IP TV streams to the
remote site.
The ‘source’ Re
-Caster takes the local multicast
(or unicast) stream and makes it available for
remote Re-Casters to access via the internet (or
VPN). The remote (‘sink’) Re
-Caster connects to
the ‘source’ Re
-
Caster and ‘pulls’ the IP TV
channel stream across. The video and audio
stream is encrypted as it passes across the
internet and any missing or re-ordered packets
are corrected. The ‘sink’ Re
-Caster then
transmits the IP TV channels on the remote LAN
as a multicast stream so they can be viewed on
settops or PC/MACs. The whole SRT transfer
process adds a second to the stream latency.
