Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
a) A bit stream containing compressed video, audio, and timing information. b) Multiplex of several audio and video PES using the same clock. c) Combines one or more packetized elementary streams (PES), which have a common time base into a single stream. The program stream was designed for use in relatively error-free environments, and is suitable for applications which may involve software processing. Program stream packets may be of variable length.
Industry:Software
a) Collection of data in a form suitable for ready reference, frequently stored in sequential memory locations. b) A table is comprised of a number of sub_tables with the same value of table_id.
Industry:Software
New technologies used to send video information over the internet. Rather than wait for the whole file to download, the video streaming technology lets the clip begin playing after only a few seconds.
Industry:Software
The sharpness or “crispness” of the picture. Resolution can be measured numerically by establishing the number of scanning lines used to create each frame of video. a) The number of bits (four, eight, ten, etc.) determines the resolution of the digital signal; 4-bits = a resolution of 1 in 16, 8-bits = a resolution of 1 in 256 (minimum for broadcast TV), 10-bits = a resolution of 1 in 1024. b) The basic measurement of how much information is on the screen. It is usually described as the number of pixels in the horizontal axis by the number of horizontal lines. The higher the numbers, the better the system’s resolution. Some typical resolutions are: NTSC VHS - 240 x 485; NTSC broadcast - 330 x 485; NTSC laserdisc – 425 x 485; ITU-R BT.601 (525/60) - 720 x 485; Computer screen – 1280 x 1024. c) The capability of making distinguishable individual parts of an image. A measure of how clear the picture looks. d) Perceivable detail. See also Chroma Resolution, Diagonal Resolution, Dynamic Resolution, Horizontal Resolution, Spatial Resolution, Static Resolution, and Temporal Resolution. e) The amount of detail in an image. Higher resolution equals more detail. Generally expressed in “lines.” It is the number of vertical line pairs that the system can distinguish, and has no relationship to the number of horizontal scan lines.
Industry:Software
An electronic process which allows the viewing of two video images, side by side or above and below, on-screen simultaneously.
Industry:Software
To move an object without rotation in a straight line, either left or right, up or down, in or out, or any combination thereof, in three-dimensional space.
Industry:Software
A camera tube in which a low-velocity electron beam scans a photoemissive mosaic on which the image is focused optically and which has electrical storage capability.
Industry:Software
Integrated circuit memory that is manufactured with a pattern of all logical 0s and 1s and has a specified pattern written into it by a special hardware programmer.
