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.

Page 2: Installation
Installation This IP Re-Caster should only be used in a MediaStar 770 rack or a 769 Single ‘Blade’ chassis that has been fully installed in accordance with its safety instructions. There are no user serviceable parts within this module. Refer all servicing to qualified service personnel. - Page 3 The IP netmask, gateway and DNS server can be set in the same way. It is important to set the gateway and DNS server addresses if domain host names are to be used for stream routing. The MAC address of the unit can be found under the Unit Details/ MAC Address menu, or on the label on the bottom face of the unit.
- Page 4 Stream Routing The IP Re-Caster can be configured for a variety of stream routing use cases. Multiple use cases can be used at the same time as long as the unit is operating within its CPU, network bandwidth and memory usage constraints.
- Page 5 Note: When a SRT stream connection request comes via an internet connection, the user must configure their Firewall to forward all data from the incoming port to the specified SRT source port on the Re-Caster. Any non-SRT traffic or unauthorised SRT servers will be ignored. 5.
- Page 6 3. Click on the padlock symbol at the right-hand end of the Source field. Enter the same passphrase that the stream is being encrypted with at site A. 4. Check the Enable Destination checkbox. Select the UDP:// setting on the Destination field drop- down and enter the multicast stream address and port number that the Re-Caster will use to stream the IP video stream onto the LAN.
- Page 7 Inter-site stream transfers using a corporate VPN When there is a ‘quality-controlled’ VPN joining different corporate sites, it is possible to use Re-Casters to transfer live IP TV multicast streams across the VPN. A VPN link is rarely capable of transferring a multicast IPTV stream directly across it and so the Re-Caster on the source side (Site A) collects the multicast stream from the LAN and transfers it across the VPN as a unicast stream directed at the Re-Caster on the destination side (Sites B and C).
- Page 8 5. Set the DSCP settings for the unicast streams (TTL is not used on unicast streams). 6. Enter the logical name for the route in the Route name field (Channel 1 shown here) and then Apply the settings. 7. After a few seconds, check that an incoming data rate is shown (near the bottom of the Route entry right-pointing arrow).
- Page 9 4. Check the Enable Destination checkbox. Select the UDP:// setting on the Destination field drop- down and enter the multicast stream address and port number that the Re-Caster will use to stream the IP video stream onto the LAN. If the Re-Caster needs to stream the same IP TV channel source to another multicast or unicast address or other SRT linked site, click on the Enable checkbox on the Destination field below and add more destination addresses.
- Page 10 Unicast Stream Replication On some customer networks it is not possible to implement multicast IP TV stream distribution with IGMP. These networks can use IP TV distribution, but it does mean a single stream from the Encoder or LAN-Caster is replicated to each of the settops or PC/MAC devices that want to access it. This is not an efficient network distribution technique but sometimes it is a necessity or a stopgap before a full multicast network is implemented.

Page 11: Front Panel Operation
Unicast to Multicast Stream Replication A single Re-Caster ‘Blade’ can be used for various stream address conversion and stream replication tasks. If an IP TV live stream is received as a unicast stream from a third-party device or service, a single Re- Caster can be configured to convert it into a multicast stream, for efficient distribution across an IGMP switched network. - Page 12 Set Password - A password may be set to prevent the unauthorised modification of the unit’s configuration. A password consists of up to 1000 digits and can be administered centrally from the Media Manager software. If the password gets lost, contact Cabletime for assistance, quoting the serial number of the unit affected.
