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.
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 Media Client
A Broadcast Enterprise Server that incorporates IT server platform and storage
technologies.
Meter Bar
Contains the audio record level controls and signal meters for a channel in AppCenter.
Monitor Pane
Displays the current information for the channel. Displays a thumbnail of the clip
currently loaded in the channel and indicates the current application for the channel.
Contains a drop down menu for changing the channel’s application. For the currently
selected channel, the monitor pane is larger and has a white background.
Non Drop Frame Timecode
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. 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.
Pane
A viewing area in a primary window that contains one or more controls. The
AppCenter interface is divided into three panes, which are used to display the channel
monitors, control applications, and manage clips. To activate a pane, click on it. Only
one pane is active at a time.
Program
A clip generated from a playlist. A program includes all the media in the playlist, but
does not include any event that breaks the flow of playout such as a pauses between
events.
Protocol
A convention for data transmission that defines timing, control, format, and data
transmission.
