A transparency technique wherein the first frame of the video file is a dummy frame that supplies the color or range of colors to be rendered as transparent: the color of the chroma-key background, for example. See Transparency, Transparency Frame.

a) A memory structure in which data is entered at one end and removed from the other. A FIFO is used as a buffer to connect two devices that operate asynchronously. b) A storage device (parallel shift register) which operates as a Turing machine to buffer asynchronous data where the first data stored is the first data read out. FIFOs are used to store video and act as “rubber-band” type buffers to keep a steady video stream where memory and system clock speeds do not match. FIFOs have less delays than standard shift registers as input and output are controlled by separate clocks.

Momentary interference to the picture of a duration of approximately one field or less, and of sufficient magnitude to totally distort the picture information. In general, this term is used alone when the impairment is of such short duration that the basic impairment cannot be recognized.
Sometimes called “Hit.”

A high-speed digitizing device based on a bank of analog comparators. The analog value to be digitized is the input to one side of the comparators bank. The other comparators input is tied to a tap of a resistor ladder, with each comparator tied to its own tap. The input voltage at each comparator will be somewhere between the top and bottom voltages of the resistor ladder. The comparators output a high or a low based on the comparison of the input voltage to the resistor ladder voltage. This string of 1s and 0s are converted to the binary number.
