Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A technique used in standards conversion to compensate for the degrading effects of different field frequencies on pictures which contain movement. Different approximate proportions of successive input fields are used in each output field.

Secondary, slower memory for large files. Usually floppy disk or magnetic tape.

SMPTE Working Group H19.16 has proposed SMPTE Standard H19.161 defining the file format for the exchange of digital motion-picture information on a variety of media between computer-based systems. This flexible file format describes pixelbased (raster) images with attributes defined in the binary file descriptor, which identifies: generic file information, image information, data format, and image orientation information, motion-picture and television industry, specific information, user defined information. The draft assumes nonrealtime application, with formats for real-time to be considered as the developing technology permits.

Actually presented in the studio, with cameras feeding out to the lines as the performance is done.
Industry:Software
A display controller architecture characterized by having multiple FIFOs or write buffers. There is typically one FIFO or write buffer at the CPU interface, and one or more FIFOs in the display pipeline.
Industry:Software
When a digital image is repositioned or resized, different pixels are usually required from those in the original image.
Simply replicating or removing pixels causes unwanted artifacts. With interpolation, the new pixels are calculated by making suitably weighted averages of adjacent pixels, giving more transparent results. The quality depends on the techniques used and the area of original picture, expressed as a number of pixels or points. Compare with Interpolation (Temporal).

The final edited tape recording from a session from which copies will be made called sub masters. These may be used for some subsequent editing to create other effects.

Proposed descriptor developed by SMPTE Working Group P18.41. This proposed SMPTE recommended practice is intended to provide a method of coding video index information in which various picture and program-related source data can be carried in conjunction with the video signal. There are three classes of video index data based on type and use of the data. Class 1: Contains information that is required to know how to use the signal. Class 2: Contains heritage information for better usage of the signal. Class 3: Contains other information not required to know how to use the signal.
Industry:Software
A type of two-channel downmix for multichannel audio programs. Lo/Ro downmixes are intended for applications where surround playback is neither desired nor required.
Industry:Software
a) To take, or be capable of taking, several different signals and send them through one source. b) To combine multiple signals, usually in such a way that they can be separated again later. There are three major multiplexing techniques. Frequency division multiple (FDM) assigns each signal a different frequency. This is how radio and television stations in the same metropolitan area can all transmit through the same air space and be individually tuned in. Time division multiple (TDM) assigns different signals different time slots. Different programs can be broadcast over the same channel using this technique. More technically, the MADs use TDM for luminance and chrominance. Space or path division multiplex allows different television stations in different cities to use the same channel at the same time or different people to talk on different telephones in the same building at the same time. c) A stream of all the digital data carrying one or more services within a single physical channel. d) To transmit two or more signals at the same time or on the same carrier frequency. e) To combine two or more electrical signals into a single, composite signal.
