MediaRig Encoder SD is a feature-rich, affordably priced MPEG-2 encoder system suitable for a full spectrum of cable, satellite  and terrestrial DTV applications.Combining dramatic  improvements in the Intel platforms with Ligos’ own innovative software and hardware  design,MediaRig Encoder SD is the compact, reliable alternative that redefines the cost vs. performance tradeoff that broadcasters are often forced to address.

 
 
MediaRig Encoder SD – System Highlights :    
  • MPEG-2 real time SD encoder in a 1RU design
  • Single and Dual Channel input options
  • Analog composite or SDI video input
  • SPTS/SCPC or MPTS/MCPC Transport output
  • DVB-ASI,Ethernet UDP and file output
  • Techniques for superior quality at low bitrates
  • Customizable drag-and-drop presets
  • 500 Kbit/s to 50 mbits/s,MP@ML and 4:2:2P@ML Constant and variable bitrate operation
  • MPEG LII and Dolby Digital AC-3 audio output Closed Captioning: DVS 157,EIA 608 & 708 ATSC Static PSIP and DVB PSI/SI control tables
  • Logo (bug) insertion
  • Ligos NMS to manage up to 25 system.
 
 

The balance between video quality and bandwidth is one that operators deal with day-to-day.Bandwidth reclaimed is bandwidth  available for additional, revenue-oriented services.Until recently, there was  a sizable gap between the price and performance of  expensive high-end encoders, and those on the low end .Ligos  has developed MediaRig  Encoder SD as a high-quality encoder  thaa is ideally  suited for digital IP infrastructure , and leverages our video software experise  with the power, flexibility and price of today’s  Intel architectures.

Central to the MediaRig value proposition is the redefinition of the cost Vs performance tradeoff by which encoders have historically been judged.By using the Intel platform as the processing engine,the base system is a highly performance but very cost effective solution, By recovering bandwidth through efficient encoder and digital program insertion technologies,operators will be able to deliver more content, including major sources of revenue such as video-on-demand and localized advertising.

Further by using a host-based software processing approach, MediaRig Encoder SD can be updated easily and automatically . As new technologies become important ,MediaRigEncoder will be well suited for adaptation rather than replacement.Ligos is currently partnering with Intel corporation to bring HD and AVC/H.264 encoding and transcoding to the MediaRig platform, powered by new multi-core processor architectures that will enable MediaRig to scale with operators as their services grow.

MediaRig Encoder SD offers a variety of features that make it idealfor a number of professional applications,from broadband to ASTC DTV broadcast , fixed and mobile satellite contribution/distribution, ingest –to-archive and IPTV services .And MediaRig is proven, already in use by industry leaders such as Seachange ,Sony,Time Warner cable,Broadbus and more –a testament to the excellence and versatilityof the technologies that have made Ligos a leader in the global digital video market.
