frame-accurate and suitable for switching in
a live production environment over TCP (UDP) Ethernet based networks.
NDI is
commonly found in broadcastapplications.
●RTMP: Real-Time Messaging Protocol (RTMP) was initially a proprietary protocol developed by Macromedia (now
Adobe) for streaming audio, video and data over the Internet, between a Flash player and a server.
●RTSP:
The Real Time Streaming Protocol (RTSP) is
a network control protocol designed for use in entertainment and
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.Developedundertheauspicesof ITU, resolutions upto8192x4320 maybe compressed.
●
API:
An Application Programming Interface (API) provides a predefined function which allows accesscapabilities
andfeaturesorroutinesviaa
software or hardware, without accessing source
code or understanding the details of inner
workingmechanism. AnAPI call may execute a
function and/or provide datafeedback/report.
●
DMX512:
The communication standard developed by USITT forentertainment anddigitallighting 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.
