Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
a) The specific signal configuration, reference pulses, voltage levels, etc., that describe the input/output requirements for a particular tape of equipment. Some standards have been established by professional groups or government bodies (such as SMPTE or EBU). Others are determined by equipment vendors and/or users. b) A set of rules or characteristics defining a particular television system. Some standards (such as those contained in FCC rules and regulations) are mandatory. Most (including those of the EIA, IEEE, and SMPTE) are voluntary. The establishment of a standard often freezes development at a certain level but allows users and manufacturers to deal with a much larger array of products than might be available without a standard. There is currently one U.S. HDEP standard, the ATSC/SMPTE 1125 scanning-line system. CCIR system E is an HDTV transmission standard, used in France, calling for 819 scanning lines in a 14 MHz bandwidth.
Industry:Software
A decoder having a certain amount of buffer memory assumed to be present by an encoder.
Industry:Software
Bits added to the binary message for the purpose of facilitating the transmission and recovery of the message (e.g., frame synchronization words, check bits, etc.)
Industry:Software
Certain systems described in these standards employ feedback shift registers to modify sequences or patterns of bits in a predetermined manner or to restore such modified bit patterns to their original sequence. With outputs of suitably selected stages added modulo-2 and applied to its feedback loop, an n-stage feedback shift register will generate a bit sequence or pattern (2^n - 1) bits long before repeating. Because such repeating sequences exhibit many of the statistical properties of uniformly distributed random number sequences (e.g., their probability density and autocorrelation functions satisfy appropriate conditions),they are called pseudo-random.
Industry:Software
The functional level in which you can program the system’s baud rate, parity, and bus address to match the communications standards of an external editor.
Industry:Software
Contacts provided on the switcher to allow users to activate tally lamps on cameras, monitors, and otherwise indicate what sources are on-air.
Industry:Software
This direction also requires three numbers, and specifies the direction in which the viewer is looking, and which direction is up.
Industry:Software
A type of DVD labeling in which the pits are cut in a design to resemble writing or another image. It sometimes has the look of a hologram.
Industry:Software
In order to conform to “restricted slice structure,” all slices added together must cover the picture. This applies to Main Profile, for instance.
Industry:Software
Any country having a national group of people consisting of experts from industry and universities who develop standards for all kinds of engineering problems.
