Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Interpolation between the same point in space on successive frames. It can be used to provide motion smoothing and is extensively used in standard converters to reduce the defects caused by the 50/60 Hz field rate difference. This technique can also be adapted to create frame averaging for special effects.
Industry:Software
A synchronizing pulse generator that is the precision reference for an entire teleproduction facility.
Industry:Software
The creation of an image in the photographic or electronic medium from an image-concept (painted or generated by computer graphics, for example).
Industry:Software
The impedance or resistance (load) that a cable places on a signal being transmitted through it. In the case of a highfrequency signal, signal-to-cable matching is essential to prevent signal deterioration. The cable should be terminated by a specific load resistance, usually 50 or 75 ohms. Improper cable loading results in signal distortion, ghost images, color loss, and other adverse phenomena. Most video inputs have the proper termination built in.
Industry:Software
Involves suspension of the normal program that the microprocessor is executing in order to handle a sudden request for service (interrupt). The processor then jumps from the program it was executing to the interrupt service routine. When the interrupt service routine is completed, control returns to the interrupted program.
Industry:Software
Software option which allows user to maintain synchronization between two or more transports using one machine as control reference (master).
Industry:Software
An optional package which adds additional flags and menus to ADO 100, including Mosaics, Posterization, Solarization and Mask submenu, Target Defocus flag and Background menu, Border flags and Sides submenu.
Industry:Software
The host/local bus transfer consumes a smaller percentage of available bandwidth during video/graphics transfers than earlier bus standards but the still-noticeable performance penalty may be objectionable for some users, especially when compared to systems that circumvent it.
Industry:Software
a) A system in which the components are time-multiplexed into one channel using time-domain techniques; that is the components are kept separate by being sent at different times through the same channel. There are many different MAC formats and standards.
b) A means of time multiplexing component analog video down a single transmission channel such as coax, fiber, or a satellite channel. Usually involves digital processes to achieve the time compression.
c) A large family of television signal formats sharing the following two characteristics: color remains in a component rather than composite form, and luminance and chrominance components are time compressed so that active line time remains constant, with chrominance following luminance.
Most of the MACs also include digital audio/data channels. Since they are non-composite, MACs do not suffer from any cross-luminance or crosscolor effects. Since they are time compressed, they tend to have a greater base bandwidth than composite signals. See also ACLE, A-MAC, B-MAC, D-MAC, D-MAC, D2-MAC, HD-MAC, HD-MAC60, MAC-60, MUSE, and S-MAC.
