ARAugmented Reality.
ARCAudio Return Channel.
BNCBayonet Neill–Concelman (a type of connector, used for SDI & Genlock).
BP / BP2Backplane v2 - the infrastructure in disguise servers which houses VFC cards, e.g DisplayPort (DP).
BPCBits Per Channel - 8 or 10, usually - other standards have 12 or 16 BPC. This is what people are referring to when they say “10 bit”.
BPPBits Per Pixel. The number of data bits used to represent a 3 channel RGB (Red, Green, Blue) pixel. Normally 24 (8 x 3) but recently 30 (10 x 3).
Broadcast (multiple definitions)Distribution of audio/video content to an audience, i.e. TV; OR A reserved IP address used to send information to all devices on a network.
BSODBlue Screen Of Death - OS-level crash due to faulty drivers or hardware.

CPUCentral Processing Unit, the main chip in a computer that does number crunching.
CTDCrash to Desktop.
d3Designer, Disguise software.
DCIDigital Cinema Initiatives.
DHCPDynamic Host Configuration Protocol.
DMXDigital Multiplex (DMX512 - used for lighting control, can be used to control d3, via a module called sockpuppet).
DoFDepth of Field, the part of a camera lens which is in focus and consequently the parts of the image that are out of focus. Defined as shallow or wide - shallow means only a small part of the image is in focus, wide means that everything the camera sees is in focus.
DOFDegrees of Freedom. Number of independent variables of a system, e.g. a 2D coordinate has 2, a 3D camera pose (position and orientation) has 6. Camera lens parameters have at least 1 (focal length), but typically many (2 for lens shift, plus varying number of distortion coefficients).
