Glossary
Direct-connect storage
K2 Media Client and K2 Media Client models access their own external media
storage drives that are contained in a Lx0 RAID chasssis. Referred to as stand-alone
systems. See internal storage, shared storage.
Down Conversion
Conversion of an HD (high definition) video format to an SD (standard definition)
video format.
Drop Frame
Drop frame is a timecode adjustment that applies to NTSC video only. Due to the
framerate of NTSC, a system that normally outputs 30 frames per second must adjust
timecode by subtracting two frames every minute except every tenth minute to
achieve the effective framerate.
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 Media 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.
