Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
An extensive family of compatible digital coding standards for studio use with high-definition television is under study and test by the SMPTE Committee on Television Signal Technology (S17).
Digital representation of the 1125/60 system is documented in SMPTE 260M.

The TARGA file format (TGA) and TARGA board were developed for graphics prior to the advent of large-screen, super VGA displays.

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 idealised 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.
