K2 Summit 3G Production Client
K2 Multiformat Media Client with up to 4 HD/SD Bidirectional Channels
The K2 Summit 3G Production Client is optimized for a broad range of production and broadcast applications and is the only server that supports end-to-end SD/HD workflows in DVCPRO, MPEG-2, AVC-Intra and H.264/AVCHD formats. With bidirectional channel control, you can quickly switch between record and play. Individual channels can be software configured for additional functions as well as the creation of low-resolution streams and proxy, making the the K2 Summit 3G Production Client the most versatile server available.

MONTREAL, November 19, 2014 — High Dynamic Range (HDR) capture, an expansion of the ratio between the lightest and darkest parts of the video image, is viewed by broadcasters as the next big improvement in the viewing experience for the next generation of broadcast formats. Today, the dynamic range of television images is much lower than what the naked eye experiences in the real world, but new technology is beginning to address those limitations. Grass Valley, a Belden Brand, is taking a lead in this area and recently worked with the European Broadcast Union (EBU) to capture HDR footage during a live event for the first time.
