Drop Frame Timecode
Drop-frame time code yields precise running times, but frames are not all numbered
sequentially. A frame number must be dropped periodically to keep the clock right.
In non-drop time code, all frames are numbered sequentially, but the ending time code
of a program does not accurately give the program's length.
Ethernet
A local area network used with some remote protocol applications; it operates over
twisted wire and over coaxial cable.
Fibre Channel
A general set of integrated standards developed by ANSI for flexible information
transfer over multiple physical interface types.
FTP
File Transfer Protocol is a common IT protocol for the bulk movement or transfer of
large volumes of data. K2 Media Servers can handle multiple FTP transfers
simultaneously at faster than real-time speeds.
GPI
General Purpose Interface. GPI triggers are physical connections between two pieces
of equipment. Typically GPI triggers are based on a change of state on a monitored
pin of the serial port. For instance you could create a GPI trigger that was operated by
a port on a piece of broadcast equipment.
HD
High Definition video.
Internal storage
K2 Media Client and K2 Summit Production Client models with internal storage
access their own internal media storage drives. Referred to as a stand-alone system.
See also direct-connect storage, shared storage.
iSCSI
Internet SCSI (small computer storage interface) is a storage access protocol that can
use a transport layer such as Gigabit Ethernet rather than be restricted to the short
distances determined by computer hardware buses. K2 Media Servers use iSCSI for
clients that need to deliver media assets with real-time performance. The tuning and
optimizing done by Grass Valley permits the use of iSCSI to deliver unparalleled,
high-throughput, and deterministic performance.
K2 Summit Production Client
A Broadcast Enterprise Server that incorporates IT server platform and storage
technologies. The K2 Summit Production Client can be used with internal,
direct-connect, or shared storage.
Meter bar
Contains the audio record level controls and signal meters for a channel in AppCenter.
