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
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.
●Colour Temperature: The colour quality, expressed in degrees Kelvin (K), of a light source. The higher the colour
temperature, the bluer the light. The lower the temperature, the redder the light. Benchmark colour temperature
for the A/V industry include 5000°K, 6500°K, and 9000°K.
●Saturation: Chroma, Chroma gain. The intensity of the colour, or the extent to which a given colour in any image is
free from white. The less white in a colour, the truer the colour or the greater its saturation. Saturation is the amount
of pigment in a colour, and not the intensity.
●Gamma: The light output of a CRT is not linear with respect to the voltage input. The difference between what
you should have and what is actually output is known as gamma.
