For Immediate Release

Melville, NY - October 18, 2007: Chyron Corporation (AMEX: CGS) has today announced that WPTV, the NBC-affiliated television station for the Gold and Treasure Coasts of Florida, has installed two HD/SD-switchable HyperX² on-air graphics systems as part of its historic High Definition (HD) service.  WPTV is known on-air as NewsChannel 5 HD. 

WPTV made headlines on August 4, 2007, when it launched the first HD newscast in the history of South Florida television.  The network selected Chyron's flagship HyperX² system with the award-winning Lyric PRO advanced creation and playout software to provide continuous graphics rendering as key elements of its two main control rooms.  The first HyperX², installed in Control Room A, provides WPTV with two independent HD/SD channels; the second system, in Control Room B, delivers a single channel.

The state-of-the-art Chyron systems allow WPTV to deliver sophisticated lower third, over-the-shoulder and full-screen HD graphics for local news and weather.  The HyperX² graphics engine can simultaneously manipulate of 3D layers of text, logos, textures and movie objects, all in real time.

"This has been an exciting time for WPTV.  We managed to keep the HD launch completely under wraps, testing the workflow over a number of months.  The Chyron systems were chosen because they allow our artists and editors to push the boundaries in graphics creation and playout.  I am confident that many will love our new presentation and become even more frequent NewsChannel 5 viewers," commented Brian Lawlor, Vice President & General Manager, WPTV.

"We are very excited to be part of this historic achievement at WPTV.  The HyperX²'s open platform, advanced graphics rendering and integrated systems approach greatly benefits the broadcaster by providing a fresh new look, which in turn can drive an increase in their revenue stream," added Kevin Prince, Chyron's Chief Operating Officer.
