Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The host/local bus transfer consumes a smaller percentage of available bandwidth during video/graphics transfers than earlier bus standards but the still-noticeable performance penalty may be objectionable for some users, especially when compared to systems that circumvent it.
Industry:Software
A) A system in which the components are time-multiplexed into one channel using time-domain techniques; that is the components are kept separate by being sent at different times through the same channel. There are many different MAC formats and standards.
b) A means of time multiplexing component analogue video down a single transmission channel such as coax, fiber, or a satellite channel. Usually involves digital processes to achieve the time compression.
c) A large family of television signal formats sharing the following two characteristics: colour remains in a component rather than composite form, and luminance and chrominance components are time compressed so that active line time remains constant, with chrominance following luminance.
Most of the MACs also include digital audio/data channels. Since they are non-composite, MACs do not suffer from any cross-luminance or crosscolor effects. Since they are time compressed, they tend to have a greater base bandwidth than composite signals. See also ACLE, A-MAC, B-MAC, D-MAC, D-MAC, D2-MAC, HD-MAC, HD-MAC60, MAC-60, MUSE, and S-MAC.
Industry:Software
A) A signal that can electronically “cut a hole” in the video picture to allow for insertion of other elements such as text or a smaller video picture.
b) A video that has been overlaid on top of another video. Keys may W2 W1 B2 B1 SD 5% C Grat. B 2% K2T 5% be either determined by the luminance or brightness of the key video, or determined by the chroma or hue of the key video. c) A push-button.
Industry:Software
Contribution level quality encoded high definition television signals. Typically split into two levels: high level at approximately 140 Mbps and low level at approximately 39 Mbps (for high definition with the studio, 270 Mbps is being considered). These levels of compression are necessary for signal routing and are easily re-encoded without additional compression artefacts (concatenation) to allow for picture manipulation after decoding. DS-3 at 44.736 will be used in both terrestrial and satellite programme distribution.
Industry:Software
A feature of Indeo video interactive allowing the playback application to tell the codec to decode only a rectangular subregion of the source video image: the viewport. See Viewport.
Industry:Software
Device for combining two or more electrical signals into a single, composite signal.
Industry:Software
A miniature cassette system originated by Olympus, allowing 30 minutes of recording per side on a capstan-driven tape, 1/7" wide, running at 15/16 ips.
Industry:Software
A multi-resolution image file format developed by Kodak as part of the Photo CD System.
Industry:Software
A tally of which bus on an M/E is active regardless of whether or not it is on air.
Industry:Software
Process of transmitting more than one signal via a single link. The most common technique used in microprocessor systems is timedivision multiplexing, in which one signal line is used for different information at different times.
