●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 standardized 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 capabilities
andfeatures orroutines viaa software or hardware, without accessing source code or understanding the details of inner
working mechanism. An API 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
