Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The arrangement of magnetic particles on recording tape. In tapes designed for quadraplex recording applications, the orientation direction is transverse. For helical and longitudinal recording, it is longitudinal.
Industry:Software
The on-air or final output of the switcher as selected on the programme or line A/B bus and as keyed, mixed, or faded with the DSK.
Industry:Software
A) A computer l/O (input/output) port through which the computer communicates with the external world. The standard serial port uses RS-232 or RS-422 protocols. b) An outlet on a workstation to which you connect external serial devices.
Industry:Software
The common clock used to encode video and audio in the same program. A 27 MHz clock regenerated from PCR for a jitter-free readout of MPEG data.
Industry:Software
A display device which projects a video or computer image onto a large screen. The classic video projector has three primary colour video tubes which converge on-screen to create the full-color image.
Single tube projectors eliminate convergence problems but compared to three tube systems, project a relatively lower quality image.
Industry:Software
A unit of equal loudness for all audio frequencies. Phons are related to dB, SPL re: 0.0002 microbar by the Fletcher-Munson curves. For example, a loudness level of 40 phons would require 40 dB SPL at 1 kHz and 52 dB at 10 kHz.
Industry:Software
Video image information may be presented in a specific system with, for example, its own frame rate, line count per frame, and line resolution (if the system is analog, resolution = video bandwidth; if the system is digital, resolution = pixels per line) and need to be recast into a target system differing in one or more of the specifications. Or in post-production, it may be desirable to change image size, to crop or zoom, or to distort geometrically, etc. The original signal is sampled and the samples processed by a suitable algorithm to generate a new set of samples compatible with the specifications of the target system.
Industry:Software
A) Determination of the monochromatic components of the luminance considered. b) Objective detailed specification of a white reference, of a color, or of the transmission function, with respect to wavelength and intensity.
Industry:Software
A) A method of encoding a picture by dividing each picture into sub-pictures, performing a linear transformation on each subpicture and then quantizing and coding the resulting coefficients. b) The conversion of a signal from one domain to another, e.g., the conversion of two-dimensional picture samples into the frequency domain by means of DCT, which is used in MPEG.
Industry:Software
In a material composed of oriented particles, the orientation ratio is the ratio of the residual flux density in the orientation direction to the residual flux density perpendicular to the orientation direction.
The orientation ratio of conventional tapes is typically about 1.7.
