Primestream Announces Integration With Harmonic ChannelPort Playout Device

MIAMI -- April 16, 2012 -- Primestream(R), a leader in advanced Media Asset Management and Broadcast Automation software, announced that its acclaimed FORK(TM) Production Suite now supports Harmonic's Spectrum ChannelPort(TM) integrated channel playout platform. The combination gives media organizations control over all of ChannelPort's branding, master control switching, and clip playout functions directly from the FORK environment, making it possible for broadcasters to enrich their on-air look with graphics and up-to-the-minute tickers without having to switch between systems.

"In order to compete in today's market of 'anytime, anywhere' content, media organizations must always be ready with the next great branded channel or service -- a big challenge considering they must also cut costs at the same time," said Primestream CEO Claudio Lisman. "Our integration with Harmonic's ChannelPort playout device will help FORK and ChannelPort users meet this challenge by further automating and simplifying workflows so that it's faster and more affordable to bring new content to air. Primestream wanted to support the ChannelPort workflow because we believe that Harmonic is the industry's most trusted media server platform, and therefore a broad array of users would benefit."

The newest member of the Harmonic Spectrum(TM) media server family, ChannelPort is a next-generation branded playout solution that combines clip playout functionality with critical channel-branding capabilities to simplify integration and workflow, lower equipment purchase expenditures, and reduce maintenance and operations costs -- functions and benefits that are controlled via the FORK interface.

Primestream's integration with ChannelPort adds to its current support of Harmonic's MediaGrid(TM) storage system in the FORK automation workflow, which enables MediaGrid users to control everything -- from ingest to edit, playout to render. FORK can simultaneously record multiple concurrent streams of HD video straight to the MediaGrid, allowing live proxy generation with customized metadata and immediate live editing. Integrated Media Asset Management provides a window into content and accelerates workflow with dynamic search tools and powerful scripts and triggers to automate tasks based on metadata status.

Primestream is demonstrating FORK's integration with both ChannelPort and MediaGrid at the 2012 NAB Show in booth SL6605. More information about Primestream, B4M, and their products is available at www.b4m.com or www.primestream.com.
