Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
a) The algorithm used to capture analog video or audio onto your hard drive.
b) Used to implement the physical combination of the coding and decoding circuits.
c) A device for converting signals from analog to coded digital and then back again for use in digital transmission schemes. Most codecs employ proprietary coding algorithms for data compression. See Coder-Decoder.
Industry:Entertainment
The number of bits recorded per track length unit, usually expressed in terms of kilobits per inch (KBPI) or bits per millimeter (BPMM).
Industry:Entertainment
a) A number (often a constant) that expresses some property of a physical system in a quantitative way. b) A number specifying the amplitude of a particular frequency in a transform.
Industry:Entertainment
Byte-wise transmission of digital video down a multi-conductor cable where each pair of wires carries a single bit. This standard is covered under SMPTE125M, EBU 3267-E, and ITU-R BT.656 (CCIR 656).
Industry:Entertainment
The tangential force required to maintain (dynamic coefficient) or initiate (static coefficient) motion between two surfaces divided by the normal force pressing the two surfaces together.
Industry:Entertainment
Video RAM containing formatted graphics data for VGA and SVGA systems where four or more bit planes can be addressed in parallel.
A bit plane is sometimes called a map.
Industry:Entertainment
The relative increase in the linear dimension of a tape or base material per percent increase in relative humidity measured in a given humidity range.
Industry:Entertainment
a) The rate at which the compressed bit stream is delivered from the storage medium to the input of a decoder. The digital equivalent of bandwidth. b) The speed at which bits are transmitted, usually expressed in bit per second (IEEE 100). Video information, in a digitized image for example, is transferred, recorded, and reproduced through the production process at some rate (bits/s) appropriate to the nature and capabilities of the origination, the channel, and the receptor. c) The amount of data transported in a given amount of time, usually defined in Mega (million) bits per second (Mbps). Bit rate is one means used to define the amount of compression used on a video signal. Uncompressed D1 has a bit rate of 270 Mbps. MPEG-1 has a bit rate of 1.2 Mbps.
Industry:Entertainment
The relative increase in the linear dimension of a tape or base material per degree rise in temperature (usually Fahrenheit) measured in a given temperature range.
Industry:Entertainment
Measured in oersteds, the measurement of a magnetic characteristic.
The demagnetizing force required to reduce the magnetic induction in a magnetic materiel to zero from its saturated condition.
