Ligos Introduces MediaRig™ Core

New MPEG Encoding and Transcoding Platform for Broadcast, Broadband and Professional Video to Debut at NAB2003

San Francisco, CA – (March 18, 2003) Ligos Corporation today announced MediaRig Core, its latest MPEG product for Broadcast, Broadband and Professional video applications. MediaRig Core is a multi-standard, software-based video processing “engine” that assembles all the software and interfaces required to transform the PC platform into an affordable professional-class real-time encoder or transcoder. Ligos will be debuting MediaRig Core at the National Association of Broadcasters show, NAB2003, at the Las Vegas Convention Center, April 5-10 2003, in the South Hall at Booth #SL1656.

“MediaRig Core represents a two year effort to bring our innovative approaches to these high-end video markets,” said Mark Koziol, President and CEO of Ligos Corporation. “Many in these industries are struggling with a dizzying array of requirements for video, but find themselves encumbered by inflexible and costly hardware-based solutions. MediaRig Core is truly the first alternative to hardware-based MPEG encoders that doesn’t sacrifice the performance, quality and reliability that’s required for Broadcast, Broadband and Professional video applications.”

MediaRig Core’s scaleable, modular software allows video system developers and manufacturers to meet application-specific requirements on an as-needed basis. It not only provides a more cost-effective path to equivalent reliability and performance associated with “black box” encoders, but also surpasses the picture quality of those encoders. Video system providers can use MediaRig Core to incorporate flexible encoding features – live real-time encode, file transcode, stream transrating, dual stream processing – wherever required. By taking advantage of the ever-growing power of general-purpose processors and the latest in Ligos’ award-winning real-time software, the MediaRig Core provides high performance and pristine quality in a variety of formats with a wide range of powerful features.
