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.

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.
