Multi Format SD/HD, MPEG-Encoder for Digital Media Distribution over IP (779)

Multi Format SD/HD, MPEG-Encoder for Digital Media Distribution over IP (779)

The MediaStar Evolution range of MPEG Encoders are a powerful and ultra reliable, solid state "out of the box" solution for all encoding needs and when used in conjunction with the MediaStar DVB-T and DVB-S LAN-casters, will meet your entire IP Television Headend, Digital Signage and Digital Media encoding and IP distribution requirements.

Models: 779-S-SD, 779-S-720p, 779-S-HD, 779-S-HLS.

  • Supports both SD & HD MPEG encoding
  • Compatible with virtually all video input interfaces and resolutions
  • Auto configuration with Evolution Media Manager Software
  • Solid and robust metal case
  • Output resolutions up to 1080i50/60 1080p25/30
  • Compatible with standard viewers/
    QUICK TIME© & HLS clients
  • Easy software upgrade path; SD to HD, HD to HLS operation
  • Low power consumption (20W)

The MediaStar Evolution MPEG encoder streams live video and audio feeds from cameras, set top boxes and DVD players to distribute news, sport and entertainment directly onto your IP network.

The unit is stand-alone, housed in a robust metal case with front panel display and controls and rear panel video inputs.

Its unique multi format input circuitry allows users to input content in a wide variety of video and PC formats, HDMI; YPbPr; S-Video and CVBS as well as RGBHV. In addition the 779 has an onboard scaling engine, providing the ability to transcode SD TV inputs to HD resolutions.

Each unit can encode an incoming digital or analogue video to an H264 or MPEG2 format at either HD or SD resolution and stream it over an IP network to any PCs using the MediaStar Evolution desktop viewing software (Part 761) or video screens equipped with MediaStar Evolution Digital Media Decoder (Part 780). In addition, in HLS mode it can stream to a MediaStar HLS server (Part 700-469) to serve iOS or Android laptops, tablets and smartphones.

Initial configuration and stream setup using a laptop or tablet can be via the built in web server with its advanced web UI or by simply using the front panel buttons and LCD status display. Alternatively, multiple units within a system can be networked under the control of the Evolution Media Manager software (Part 467).

Front panel RS232 and USB Comms connectors allow local connectivity and can also be utilised to pass IP command signals generated by remotely located Touch Screens and management systems, for control of headend located RS232 devices.

Twin Infra red blasters support IR Routing. This enables IR commands from III party RCUs to be passed back from any display screen equipped with a MediaStar Media Decoder (Part 780) to the 778 for the control of other headend located IR devices.

A unique SD to HD, HD to HLS software upgrade option enables cost effective SD system implementation with future proofed full HD or HLS capability ensured, all with no hardware change.

This coupled with maintenance free operation, small physical size and low power consumption make the 779 ideally suited for both large scale distributed applications or simple single unit deployments.
