Glossary
24fps (24p) – refers to a video format that operates at 24 frames per second frame rate with progressive
scanning.
5 GHz - Wireless technology using the unlicensed 5GHz frequency bands.
50 Hz – Common Frame rate (image change rate) for video within Europe.
60 Hz - Common Frame rate (image change rate) for video within America/Japan.
5.1 – Surround sound that delivers 6 channels of audio, 5 standard speakers and 1 Sub-woofer.
7.1 – Surround sound that delivers 8 channels of audio, 7 standard speakers and 1 Sub-woofer.
A
ADC (A/D Converter) – A IC Chip that converts analogue signals into digital.
AV – Products for recording, processing or reproduction of picture and/or sound are given this label.
B
Bit - In computer and digital terminology a bit is the smallest unit of data. It is expressed in binary notation
so that it is either 0 or 1 - basically an ‘off’ or an ‘on’ switch. The word ‘bit’ is an amalgam of ‘binary’ and
‘digit’.
Bit rate – The number of bits that are transferred or processed per unit of time.
Bitstream - is the digital form of multi-channel audio data (e.g., 5.1 channel)
before it is decoded into its various formats.
Block Noise Reduction – MPEG digital video compression works by compressing square areas of pixels.
Under some conditions, an artifact called block noise can occur in the picture. Block Noise Reduction
processes the noise blocks so that they become less visible.
Blu-ray - The Blu-ray Disc™ is a high-density optical disc format designed for storage of high-denition
video and data.
C
Coaxial Digital Audio - Coaxial digital cables are the most common type of connection cable used for
digital audio. They look similar to the RCA cables that many people use and are familiar with. The only
difference is that it carries digital instead of analog signals.
Component Video - video signal is separated into its component form i.e. red, green(sync) and blue
and referred to as YUV. (also see YPbPr and YCbCr). Component Video signal is the same as YUV where
Y = luminance Pb = blue minus luminance and Pr = red minus luminance.
Composite Video - The composite video signal is where the luminance and chrominance are mixed
together with sync information down a single cable.
Chrominance - is the signal used in video systems to convey the color information of the picture.
