communications systems to control streaming media servers. The protocol is used for establishing and controlling
media sessions between end points.
●MPEG: Moving Picture Experts Group is a working group formed from ISO and IEC developing standards that
allow audio/video digital compression and Transmission.
● H.264: Also known as AVC (Advanced Video Coding) or MPEG-4i is a common video
compression standard.
H.264 was standard
ized by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC JTC1 Moving
Picture Experts Group (MPEG).
● H.265: Also known as HEVC (High Efficiency Video Coding ) H.265 is the successor to the widely used
H.264/AVC digital video coding standard. Developed under the auspices of ITU, resolutions up to 8192x4320 may
be compressed.
●
API:
An Application Programming Interface (API) provides a predefined function which allows access
capabilitiesandfeaturesorroutinesviaa
software or hardware, without accessing source
code or understanding the
details of inner working mechanism. AnAPI call may execute a
function and/or provide datafeedback/report.
●
DMX512:
The communication standard developed by USITT for entertainment and digital lighting systems.The
wide adoption of the Digital Multiplex (DMX) protocol has seen the protocol used for a wide
range of other devices
including video controllers.
DMX512 is delivered over cable of 2 twisted pairs with 5pin XLR cables for connection.
●ArtNet: An ethernet protocol based on TCP/IP protocol stack, mainly used in entertainment/events applications.
Built on the DMX512 data format, ArtNet enables multiple “ universes ” of DMX512 to be transmitted using
ethernet networks for transport.
●
MIDI:
MIDI is the abbreviation of Musical Instrument Digital Interface. As the name indicates the protocol was
developed for
communication between electronical musical
instruments and latterly computers. MIDI instructions are
triggers or commands sent over twisted pair cables, typically using 5pin DIN connectors
.
●OSC:
The principle of Open Sound Control
(OSC) protocol is for networking sound
synthesizers, computers, and
multimedia
devices for musical performance or show control. As with XML and JSON, the OSC protocol allows
sharing data. OSC is transported via UDP packets between devices connected on an Ethernet.
●Brightness:
Usually refers to the amount or intensity
of video light produced on a screen without regard to colour.
Sometimes called black level.
●
Contrast
Ratio:
The ratio of the high light output level divided by the low light output level. In theory, the
contrast ratio of the television system should be at least 100:1, if not 300:1. In reality, there are several
limitations. Well-controlled viewing conditions should yield a practical contrast ratio of 30:1 to 50:1.
