Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A) European video standard with image format 4:3 aspect ratio, 625 lines, 50 Hz and 4 MHz video bandwidth with a total 8 MHz of video channel width. PAL uses YUV; The Y component represents Luminance, the U component represents B-Y, The V component represents R-Y. The V component of burst is inverted in phase from one line to the next in order to minimise hue errors that may occur in colour transmission. b) The colour television transmission standard used in Europe and other parts of the world. This standard uses a subcarrier which is alternated 90 degrees in phase from one line to the next to minimise hue errors in colour transmission. PAL-I uses a 4.43361875 subcarrier. A single frame (picture) in this standard consists of 625 scanning lines. One frame is produced every 1/25 of a second. PAL-M uses a 3.57561149 MHz subcarrier and 525 scanning lines. One frame is produced every 1/30 of a second. c) The television and video standard in use in most of Europe.
Consists of 625 horizontal lines at a field rate of 50 fields per second. (Two fields equals one complete frame.) Only 576 of these lines are used for picture. The rest are used for sync or extra information such as VITC and Closed Captioning.
Industry:Software
A type of scalability where an enhancement layer also uses predictions from pel data derived from a lower layer without using motion vectors. The layers can have different frame sizes, frame rates or chroma formats. Spatial scalability offers a layering of the picture resolution, suitable for HDTV transmissions, for instance. By decoding of the lower layer, a “normal” picture is obtained, and by decoding of the enhancement layer, the HDTV picture may be constructed.
Industry:Software
Segment of the machine-language instruction that specifies the operation to be performed. The other segments specify the data, address, or port. For the 8085, the first byte of each instruction is the opcode.
Industry:Software
A row of crosspoint push-buttons used to select the on-air background output of the switcher.
Industry:Software
Digital information that is transmitted in serial form Often used informally to refer to serial digital television signals.
Industry:Software
When the operating system fails and the system will not accept keyboard or mouse input.
Industry:Software
A method of encoding the PCM NTSC signal by reversing the encoding phase on alternate lines to align the code words vertically.
Industry:Software
A socket on a VCR or video camera which when connected, permits remote control of the unit. Remotes may be wired or wireless (infrared) and allow such control as play, pause, record, fast forward, and rewind. See Edit Control.
Industry:Software
Device that converts one component format to another, e.g., to convert (Y, R-Y, B-Y) signals to (RGB) signals.
