Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A) The modulation sidebands of the colour subcarrier contain the R-Y and B-Y information. For NTSC, the subcarrier frequency is 3.579545 MHz. For PAL the subcarrier is approximately 4.43 MHz. b) An auxiliary information carrier added to the main baseband signal prior to modulation. The most common example in television is the NTSC colour subcarrier.
Many ATV schemes propose adding additional subcarriers to NTSC.
c) A sine wave which is imposed on the luminance portion of a video signal and modulated to carry colour information. Subcarrier is also used to form burst. The frequency of the subcarrier is 3.58 MHz in NTSC and PAL-M and 4.43 MHz in PAL. d) The high-frequency signal used for quadrature amplitude modulation of the colour difference signals.
Industry:Software
A mechanism defined in SMPTE 298M used to identify the type and encoding of data within a general purpose data stream or file.
Industry:Software
A waveform monitor display mode in which the Y and two chrominance components of an analogue component video are shown side by side on the waveform screen.
Industry:Software
Technique used to facilitate the troubleshooting of digital circuits. Nodes of the circuit, stimulated during a test mode, produce “signatures” as the result of the data compression process performed by the signature analyzer. When a node signature is compared to a known good documented signature, faulty nodes can be identified.
Industry:Software
A type of scalability where an enhancement layer also uses predictions from pel data derived from a lower layer using motion vectors. The layers have identical frame rates size, and chroma formats, but can have different frame rates.
Industry:Software
This is a name for the contrast or picture control. It describes a function that is otherwise not clearly spelled out in names of controls used on monitors. It is not a term found on a monitor control. (As “black level” clearly defines the brightness control function, “white level” more clearly defines the contrast or picture control function.) White Noise - A random signal having the same energy level at all frequencies (in contrast to pink noise which has constant power per octave band of frequency).
Industry:Software
This allows the material positioning of video images to be checked. Both safe title and safe action boundaries are included. This signal can be keyed by any switcher or special effects generator that incorporates the luminance keying function.
Industry:Software
This is a measurement of the colour oscillator frequency and phase as set by the colour burst in relation to the 50% point on the leading edge of the horizontal sync pulse.
Industry:Software
A code in the Universal Label created by concatenating the first two sub-identifiers for ISO and ORG. For the SMPTE UL, this field must be “2B” in hexadecimal (hex) notation (0x2B).
Industry:Software
A multi-conductor cable carrying simultaneous transmission of data bits. Analogous to the rows of a marching band passing a review point.
