Application System
Application System
The Application system architecture is similar to that of standard PC-type computers.
It uses an ATX form factor motherboard that provides PCI board slots for expansion,
built in Ethernet, and USB ports.
Standard boards are as follows:
• Graphics Board — This board provides enhanced performance for screen graphics
and a connection for a VGA monitor.
• RS422 Boards — The K2 Media Client has two RS422 boards. These standard
boards provide four RS-422 ports for connecting remote control devices.
• Dual Ethernet Board — This board provides additional Gigabit Ethernet ports,
which are used for redundant connections.
• RAID Controller — This board provides the RAID functionality and SCSI
connection for the internal disk drives. This includes both media and system drives
for internal storage models, but just the RAID 1 pair of system drives for external
storage models. The external ports on this board are not used.
The Application system uses a Windows operating system upon which all K2 Media
Client applications run for configuration and control of the unit.
Real Time System
The Real Time system uses Grass Valley boards to provide the core video disk
recorder functionality. Primary components are as follows:
• Real Time Processor (RTP) Board — This board provides a dedicated processor
and connections for media access and processing. It functions as a riser board,
connecting to the PCI slot below and the Codec board above.
• Codec Board — This board hosts the circuits responsible for encoding/decoding
video and processing audio and timecode. It also provides the majority of the
media-related input and output connectors.
• XLR Board — This board provides XLR connectors, which are used for LTC
inputs and outputs. It is primarily an extension of the codec board to allow the
space and orientation required for XLR connections.
The Real Time system uses a dedicated operating system. This operating system runs
on the RTP board and manages all the hardware involved in controlling the flow of
video, audio, timecode, genlock, and GPI in and out of the K2 Media Client.
