Name Description
Balanced Audio In audio, the opposite of Unbalanced. Balanced refers to a type of AC electrical signal having two "legs" independent of ground. One is generally considered positive (+) and the other negative (-) in voltage and current flow with respect to ground. XLR cables and TRS 1/4 inch cables are designed to transmit balanced audio from one balanced device to another.
Bandwidth Bandwidth refers to how much data you can send through a network or modem connection. It is usually measured in bits per second, or "bps".
Bayer Array A CCD or CMOS sensor that has an individual red, green or blue filter over each pixel to synthesize color information from a grayscale sensor. The "Bayer" pattern is also called a Color Filter Array (CFA). It is named after Bryce E. Bayer, the Kodak engineer who invented it. The colored filters are arranged so that out of each four-pixel group, two will be green, one red, and one blue. Bayer found that because human perception was more sensitive to luminance (brightness) information in the green portion of the spectrum, increasing luminance resolution by using more green pixels meant more perceived sharpness in the final image. Color for each individual pixel is created by examining the color of the pixels around it and then processing this information through a sophisticated mathematical algorithm.
Black Point Describes the number of steps of tonal resolution, or brightness levels, that the dynamic range is divided into when it is quantized by the Analog to Digital converter. Bit depth is specified in base 2 notation. Eight bits is 28 or 2 raised to the 8th power. Eight bits equals 256 steps or levels of information. Twelve bits is 212 and equals 4096 levels. Sixteen bits is is 216 and equals 65,536 levels.
Bluetooth This wireless technology enables communication between Bluetooth-compatible devices. It is used for short-range connections between desktop and laptop computers, smartphones, printers, headphones, and any bluetooth enabled device.
Blu-ray Blu-ray is an optical disc format such as CD and DVD. It was developed for recording and playing back high-definition (HD) video and for storing large amounts of data. While a CD can hold 700 MB of data and a basic DVD can hold 4.7 GB of data, a single Blu-ray disc can hold up to 25 GB of data. Even a double sided, dual layer DVD (which are not common) can only hold 17 GB of data. Dual-layer Blu-ray discs will be able to store 50 GB of data. That is equivalent to 4 hours of HDTV.
Blu-ray Region Code Blu-ray disc are region coded in a similar fashion to a system used to region code DVDs. However, instead of eight official regions used for coding DVDs, for Blu-ray Discs, there are only three regions, designated as follows: Region A: U.S., Japan, Latin America, East Asia (except China). Region B: Europe, Africa, Australia, New Zealand Region C: China, Russia, India, remaining countries. However, despite the provisions for Blu-ray Disc region coding, many Blu-ray Discs are released without region coding. In this case, then you may be able to play a non-region coded disc that is released in another area of the World.
Bridge In computer networking, a bridge serves the same purpose. It connects two or more local area networks (LANs) together.
Brightness The attribute of visual perception in accordance with which an area appears to emit more or less light. (Luminance is the recommended name for the photo-electric quantity which has also been called brightness.) Brightness is measured in lumens on a projector.
Brightness Value (Gray Level, Gray Value, Pixel Value, Digital Number) - The brightness of a pixel described as a number. Brightness levels range from 0 for black to 255 for white in an 8-bit image. They can range from 0 to 4095 for a 12-bit image, and 0 to 65,535 for a 16-bit image.
Broadband This refers to high-speed data transmission in which a single cable can carry a large amount of data at once. The most common types of Internet broadband connections are cable modems (which use the same connection as cable TV) and DSL modems (which use your existing phone line).
