MediaStar 700-485 Transcoder Installation Guide
The MediaStar Multistream Transcoder
(700-485) is a dedicated 1RU
processing unit for transcoding multiple
live IPTV streams. It provides video
and audio format and picture resolution
conversion, with bitrate-controlled
stream transmission on a multicast
LAN.
The Transcoder can take a range of off-air and
internally generated IPTV streams and convert
them all to a common picture resolution, video
standard and bitrate, for consistent distribution
across a corporate LAN or WAN.
It will accept up to 20 single-program, unicast
or multicast, UDP MPEG2 transport streams with
MPEG2, H264 or H265 encoded video and
MPEG, AAC or digitally encoded audio. The
incoming video can be transcoded to either
H264 or H265 and the audio is converted to
stereo AAC.
The incoming stream picture resolution may be
changed to any setting in the standard 480p to
1080p range, although high upscaling is not
recommended for picture quality reasons.
H265 encoded video provides a picture of equal
quality to MPEG2 or H264, but at significantly
lower stream data rates. It should be noted
though, that 780 units do not play H265 video
streams.
What's in the box:
•
700-485 1RU Transcoder
•
Rack Mounting Kit
•
AC mains power leads
The Transcoder can also produce a separate G711
network audio stream of the TV audio, for
transmission to third party audio distribution
systems. The phasing of the G711 audio stream
can be adjusted so playback through a third-party
system can be synchronized with large screen
video playout using MediaStar 782 or 780 units.
The Transcoder is a full depth, 1RU unit, with dual
redundant, hot swappable power supplies. The
unit is supplied with a rack mounting kit and dual
AC mains supply leads.
Configuration is via web page menus provided by
the Transcoder itself. The unit can be used
standalone or with Media Manager software which
will monitor the unit and provide drag and drop
media icons for all the transcoded streams.

Installation Before installing the MediaStar 700-485 Transcoder, ensure that the Regulatory Requirement Notices and Important Safety Instructions at the beginning of this guide have been read. Ensure that the mains supply has an adequate capacity and a reliable protective earth connection, particularly when power distribution strips are used in equipment racks. - Page 4 If the local account passwords are lost, they cannot be reset so the Transcoder will need to returned to Cabletime for a full system re-install. The default passwords for user ‘cabletime’ and user ‘root’ are: cabletime Use the local monitor, keyboard and mouse for the following actions: 1.
- Page 5 Disabling a. At the login prompt, login as user ‘cabletime’ (if automatic login is not configured). b. Double click the ‘Terminal’ icon on the desktop. c. Enter ‘sudo disable-autologin’. d. Enter the password for the ‘cabletime’ user if prompted. 4. Enabling and Disabling Remote Access via SSH By default, SSH access to the Transcoder is disabled.

Reset checkboxes are located here. Set Password - A password may be set to prevent the unauthorised modification of the unit’s configuration.
- Page 7 Transcoder Configuration Connect to the Transcoder’s configuration web pages using a PC/MAC and Web browser software (e.g. Edge, Chrome or Firefox), by entering the Transcoder’s IP address into the browser’s address bar. Click through any warnings and the Transcoder’s specification page will then be shown. Click on the Transcoder Config page link on the left-hand side panel and configure the Transcoder for use.
- Page 8 6. The G711 Delay field can be set to delay the G711 audio stream in relation to the outgoing transcoded IPTV stream. This delay can be set to synchronise low latency audio system playout with screens being fed from 780 or 782 units decoding the main transcoded stream. The units specified are milli-seconds (mS).
