Trilithic, RGB Partner on Multicast Digital EAS

Trilithic, RGB Team Up for Multicast Digital EAS Trilithic, a provider of digital emergency alert systems, has announced a partnership with RGB Networks, a developer of network video processing technology to integrate Trilithic’s EASyCAST EAS System with RGB Networks’ Broadcast Network Processor (BNP) to deliver digital emergency alert message overlays for DTV multicasts.

EAS messages, tests and alerts are required on all program streams, but currently, many broadcasters use a combination of analog, analog upconverting and various graphics logo inserters to provide mandated EAS messaging. This means additional upconverting and patchwork.

With the RGB Networks BNP combined system for broadcast TV, all services in the broadcaster's ASI stream, including audio replacement, can have EAS crawl messages with audio, overlaid directly onto all video streams. The allows broadcasters to selectively target the delivery of EAS messages to some or all video program streams, as well as target specific transmitters covering different DMAs or all DMAs on the entire network. EAS messages and graphics are inserted in real-time without the need to demux or decode the ASI stream.

In addition to the EASyCAST and BNP handling digital EAS overlays, the BNP optionally supports logo insertions, snipes, PIP and full motion graphics.

Complementing the ability to target the delivery of EAS messages in-stream for DTV, Trilithic’s EASy Compliance Assistant software automatically handles EAS log-file downloads, file archiving and FCC compliance reporting for all weekly and monthly tests and from over the network. This ensures compliance with FCC regulations, but without having multiple personnel individually handling the EAS requirements. One person can review, monitor and manage all EAS functions at all transmitters from a laptop for entire group of broadcast stations.

Trilithic will demonstrate the new integrated system at the PBS Technology conference, April 12-13 in Las Vegas, and the 2009 NAB Show, April 20-23, also in Las Vegas.
