MediaStar Multi Format Input MPEG2 H264 HLS Encoder for Media Distribution over IP (778)

The MediaStar 778 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 and is a 'hot swappable' blade that easily fits into a MediaStar Powered Chassis (Model 770) or single unit appliance case (Model 769)..

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 778 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 Media Portal (Model 470) or video screens equipped with MediaStar Digital Media Decoder (Model 780 or 782). In addition, in HLS mode it can stream to a MediaStar Live Streaming Server (HLS) Model 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 MediaStar Media Manager software (Model 462).

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 (Model 780 or 782) 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 778 ideally suited for both large scale distributed applications or simple single unit deployments. Please see model options below.
