AUTHORING
The process, tools, and working environment by which content elements and functions are compiled, formatted,
coordinated, and tested for presentation on target systems. Comment: Authoring in the context of digital cinema does
not necessarily result in inseparably married or muxed content components. Rather, reference is made to a virtual
answer print, the elements of which may subsequently be subdivided or combined, encrypted in whole or part, and
packaged in various ways for distribution of the title, a version of the title, or an update for revision of the title in the
field.
AUTOMATION
A system used in a theatre projection booth that responds to cues, commands or relay switches and then controls
various elements of presentation, such as:
• picture format and corresponding lens (flat or scope)
• sound format and corresponding cinema processor settings
• curtain movement and position
• lighting level in the auditorium
• non-sync play and fade in/out
• digital cinema projector
NOTE: Christie's optional automation system is not yet available.
AUTO SOURCE
The ability of the projector to automatically recognize and synchronize to the horizontal and vertical scan frequencies
of an input signal for proper display.
BANDWIDTH
The frequency range of the projector's video amplifier.
BAUD RATE
The speed (bits-per-second) at which serial communications travel from their origin.
BIT DEPTH
The total number of bits available to represent each pixel or color sample in a digital imaging system. Using linear
binary coding, the total number of resolution steps available is equal to 2 raised to the power of the bit depth.
BLANKING TIME
The time inside one scan line during which video is not generated. The blanking time of the input signal must be equal
to or greater than the retrace time of the projector.
BRIGHTNESS
In cinema projection, brightness usually describes the amount of light emitted from a surface such as a screen. It is
measured in footlamberts or candelas per square meter.
