Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
A geographic region that led the opposition to the ATSC proposal when it was presented to the CCIR as a proposed worldwide standard and is developing its own ATV systems. European television currently has 625 scanning lines and 50 field per second as opposed to NTSC’s 525/59.94.

A European forum for standardization with participation of major players in the telecommunications industry. ETSI replaced the CEPT in 1988 with the objective of making the telecommunications standards needed for the implementation of the common market in Europe. ETSI has now become a leading body on all telecommunications standards, however, and provides a strong input to international bodies. This being so, the ETSI focuses on standards that involve interactions between public and private networks, and specifies the framework of activities that form the telecommunications infrastructure. ETSI produces standards through a number of technical committees, and uses project teams composed of paid experts to produce drafts of standards. The standards produced are called European Telecommunications Standards (ETS) or Interim European Telecommunications Standards (I-ETS).

a) The government agency responsible for (among other things) the regulation of the electromagnetic spectrum utilization in the United States, and the body that licenses radio and television broadcast stations. The FCC is an independent government agency, which answers directly to Congress. b) The FCC rules and regulations constitute mandatory standards for broadcasters, CATV operators, transmission organizations, and others. See also ACATS.

Discrete cosine transform coding in which every block consists of lines from one field. The chrominance blocks in the 4:2:0 format must never be coded by using field DCT coding, but it is allowed to use field-based prediction for this type of block.

The data signal is used to modulate the frequency of a “carrier” having a frequency much higher than any spectral component of the data signal. Permits the recording of DC or very low signal frequencies.
Industry:Entertainment
Dual carrier FM-coded discrete stereo transmissions, analogue.
Can be used for bi-lingual operation under user selection, but no autoselection is available. Audio characteristics better than standard mono soundtrack.

Takahiko Fukinuki and the Fukinuki Hole named for him.
Fukinuki is a Hitachi researcher who proposed filling an apparently unused portion of the NTSC spatio-temporal spectrum with additional information that might be used for ATV. The signal that fills a Fukinuki hole is sometimes referred to as a Fukinuki subcarrier. It is extremely similar to the color subcarrier and can cause an effect like cross-luminance under certain conditions.
Industry:Entertainment
A Hitachi ATV scheme filling a Fukinuki hole for increased luminance detail, with recent proposed additions to increase chroma detail.
