OVERVIEW
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.
K2 Summit 3G media servers are now available with IP I/Os for SMPTE 2022-6 connectivity, either installed at the factory or as a field upgrade kit. See the K2 Summit IP I/O webpage for more information.
