Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The PASC is very close to the Layer 1 subset in the MPEG audio specification. The algorithm, which is used in the DCC system from Phillips, provides a 384 kbit/s data stream.
Industry:Software
A color as far from white, black, or gray as it can be (e.g., vermilion rather than pink).
Industry:Software
Sampling within samples. For example, dividing an NTSC pixel into three or four sub-pixels is an example of sub-sampling. Some ATV schemes use such pixel subdivision to transmit a high-definition image over a sequence of multiple fields or frames, with only one sub-pixel being transmitted per field or frame. The resulting potential artifacts include motion surprise and twinkle.
Industry:Software
The particles of gamma ferric oxide used in conventional magnetic tape are acicular, with a dimensional ratio of about 6:1.
Industry:Software
The study of the distortion (error) of a lossy coding algorithm as a function of the bit rate. Rate distortion theory sets the lower bound on the bit rate as a function of the distortion.
Industry:Software
A MooV file whose resources have been moved into the data fork, creating a file that can be played on a PC. See MooV.
Industry:Software
Speed with which problems or segments of problems are performed. Throughput will vary from application to another.

Digital windowing offers a distinct advantage over analog. it digitizes the video image immediately, only converting it to analog as it is sent to the CRT. Incoming composite video is digitized and decoded to produce a YUV data stream, which then enters the video-processing pipeline (color-space and format conversion, scaling and/or zooming). After processing, the data is stored in the frame buffer. At the appropriate time, the data moves to the overlay controller, which serves as a digital multiplexer.
Graphics data remains in digital form through the overlay controller; it is not converted to analog until the final DAC that drives the CRT.
Industry:Software
One of the three types of frames used in the coded MPEG-2 signal. The frame in an MPEG sequence created by predicting the difference between the current frame and the previous one.
P-frames contain much less data than the I frames and so help toward the low data rates that can be achieved with the MPEG signal. To see the original picture corresponding to a P-frame, a whole MPEG-2 GOP has to be decoded.
