K2 Summit 3G transmission

K2 Summit 3G Transmission clients are optimized for the demands of play-to-air, providing high-capacity storage for standalone, shared storage and distributed workflows.

The Grass Valley K2 Summit 3G is a high-performance, multiformat platform that can be configured to address a wide variety of markets and applications. The flexibility of the platform enables special purpose configurations to be offered with specific capabilities at a cost-effective price.

The K2 Summit 3G Transmission client is designed to work in different storage configurations. It can function as a distributed standalone device with internal drives, or it can be a component of a K2 SAN using shared storage. K2 Summit 3G Transmission clients and servers support MPEG-2 and DV playout bit rates up to 100 Mb/s, which satisfies the majority of the world’s need for high-quality SD or HD playout.

Models can support SD or HD/SD with up to four channels, implemented as two bidirectional and two playout channels only, providing a variety of configuration options including two record and two playout channels as well as four playout channels only.

K2 Summit 3G Platform Overview

The K2 platform is comprised of one or more K2 clients connected to one or more K2 media servers and K2 RAID-protected storage. The K2 client performs all video and audio I/O using built-in encoders and decoders. More than 100 client channels can be attached to K2 media servers and RAID system. For its part, the K2 media server manages the file system and controls file transfer protocol (FTP) operations. The K2 SAN offers for RAID-5 or RAID-6 protected storage that can scale to more than 50 terabytes.

The K2 Summit 3G is a 2 RU platform with redundant hot-swappable power supplies and redundant Ethernet ports. It includes an embedded OS that runs off of a CompactFlash system drive providing fast and reliable operation. Added to this architecture is Grass Valley’s core video technology. Each channel is built around a high-performance RISC processor, an embedded real-time operating system, and perform video/audio processing in the robust and secure manner needed for a 24/7, frame-accurate environment. With built-in up/down/cross-conversion capability, it provides an effective solution for those migrating from SD to HD.

K2 Summit 3G Transmission Client

Transmission applications generally run at the most efficient bit rates possible to keep storage and transmission costs low and I/O configurations that are oriented towards playout channels. The K2 Summit 3G Transmission client is opti- mized around these requirements while maintaining the high level of ruggedness and reliability established in the K2 Summit 3G Production client. When used in a K2 SAN shared storage implementation, the K2 Summit 3G Transmission client offers two iSCSI or Fibre Channel ports to provide a backup data path in case of a failure for a cost-effective approach to no single point of return redundancy.

Transmission applications generally run at the most efficient bit rates possible to keep storage and transmission costs as low as possible. The common rate for SD MPEG is 10-15 Mb/s and HD is 25-100 Mb/s. K2 Summit 3G Transmission clients can be configured with the latest 2 TB 7.2K RPM SAS drives to cost-effectively provide the highest storage capacity in the minimum space. This offers mirrored storage of up to 1,100 hours at 12 Mb/s, 312 hours at 50 Mb/s or 156 hours at 100 Mb/s. With a wide variety of support from the world’s automation and media asset management suppliers, and the flexibility to import a variety of file formats, the K2 Summit 3G Transmission client provides a quick, easy and cost-effective solution to a diverse range of playout needs.
