Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A) A single, continuous narrow strip of the picture area containing highlights, shadows and half-tones, determined by the process of scanning. b) Horizontal or near-horizontal lines sampling a television image in the vertical direction. In tube-type cameras and displays equipped with CRTs, the scanning lines are caused by electron beam traces.

Industry:Software
Any process by which the surface smoothness of the tape coating is improved after it has been applied to the base film.
Industry:Software
A specialised oscilloscope which demodulates the video signal and presents a display of R-Y versus B-Y. The angle and magnitude of the displayed vectors are respectively related to hue (R-Y) and saturation (B-Y). The vectorscope allows for the accurate evaluation of the chrominance portion of the signal. Some vectorscopes can select either 75% or 100% colour bars. Make sure the correct mode is selected or the chroma gain can be misadjusted.

In general switcher terms, a pattern is any geometric shape which grows, rotates, or pivots and in so doing removes the foreground video while simultaneously revealing the background video. Strictly speaking, a pattern is a fully enclosed shape on the screen. This definition is our internal view, but not consistent with the industry. Typical patterns are rectangles, diamonds, and circles.
Industry:Software
A series of macroblocks, all placed within the same row horizontally.
Slices are not allowed to overlap. The division of slices may vary from picture to picture. If “restricted slice structure” is applied, the slices must cover the whole picture. If “restricted slice structure” is not applied, the decoder will have to decide what to do with that part of the picture which is not covered by a slice. Motion vectors are not allowed to point at the part of the picture, which is not covered by a slice. Note that Main Profile uses “restricted slice structure,” that is, all the slices put together must cover the picture.
Industry:Software
Signal generator designed to generate and transmit SMPTE time code.
Industry:Software
A television standard accepted in all parts of the world.
CCIR recommendation 601 is currently the closest there is to a world standard.
It is accepted throughout the world, but can be used with either 525- scanning line or 625-scanning line picture. HDTV 1125/60 Group is attempting to promote its system as a world HDEP standard, but Zenith suggests the same for 3XNTSC, and there are other candidates.
Industry:Software
Information, such as video or audio samples, which are presented at a specified time.
Industry:Software
Refers to the cross-section of an electron beam at the point of incidence in a camera tube or picture tube.
Industry:Software
An electronic device which protects electronic equipment from power fluctuations.
