- Company Profile:
Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Major French electronics firm that recently purchased GE/RCA Consumer Electronics and previously purchased German consumer electronics interests, the latter sometimes referred to as International Thomson.
Through its GE/RCA holdings, Thomson is a proponent of the ACTV ATV schemes; through International Thomson, it has proposed progressive schemes. Thomson also sells television production equipment and for a time owned the production equipment branch of CBS Laboratories, then called Thomson-CSF Laboratories.

A concept of an idealized NTSC that is identical throughout the NTSC world. Unfortunately, the NTSC standards are loose enough to allow various sub-channel schemes, though these schemes may be mutually incompatible. It is possible that some years from now an NTSC television set designed for one form of enhanced NTSC may be receiver-incompatible with transmission of another form of enhanced NTSC.

a) Deletion of lower significant bits on a digital system.
Usually results in digital noise. b) Shortening the word length of a sample or coefficient by removing low-order bits. c) To terminate a computational process in accordance with some rule. For example, when digital mixing or other operations create extra bits per sample (such as 16 bits from multiplication of two 8-bit samples), it is usually necessary at some point to truncate (or round) the result back to the original bit length, and to apply some rule to the correction of the part retained. Various rules have been introduced for how this may be done with digital video images for the least noticeable result.

Measure of resolution. A TV line is either black or white, so two TV lines (one black and one white) form one cycle of spatial resolution. TV lines are often confused with scanning lines. For vertical resolution, scanning lines multiplied by the Kell factor (and, when appropriate, by the interlace coefficient) yield TV lines.

Numbering system commonly used to represent both positive and negative numbers. The positive numbers in two’s complement representation are identical to the positive numbers in standard binary. However, the Two’s complement representation of a negative number is the complement of the absolute binary value plus 1. Note that the eighth or most significant bit indicates the sign: 0 = plus, 1 = minus.

A “bridge” ties several specifications together, In DVD, bridges are drawn to UDF, MPEG-2, and Dolby C-3.

UDTV with a 2,000-line (or more) display is being contemplated in Japan. The ideas underline the importance of scalability in future broadcast technology, and suggest that rigid standards will only have a limited life span. The MPEG-2 syntax would support the level of resolution found in UDTV, but actual tests of conformance at this resolution are not planned so far. In addition, a question of interoperability with other digital TV services will also have to be investigated.

Currently, the newest and best kind of drives for DV. New technology makes these drives better than AV optimized.

In late 1992, VESA (Video Electronics Standard Association) completed the specification for a local bus expansion for PCs.
One of the most important things about VL Bus design is that it specified connector pinout. The VL Bus, considered a high-speed bus with a maximum speed of 66 MHz, was designed with the Intel 486 in mind. The 32- bit bus, which includes unbuffered control, data, and address signals is compatible with 16-bit operations. One drawback of the VL Bus implementation is that the more expansion connectors used, the slower the operation of the bus. For example, using two connectors, the highest recommended speed is 40 MHz. When multiple bus slots are desired, multiple VL Bus subsystems can be built into a single PC.

An improved stereo audio recording/playback system found on some camcorders and VCRs. Because the audio tracks are mixed and recorded with the video signal, audio only dubbing of these tracks is not possible.
