Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Proprietary recording format developed by Ampex that uses a 19 mm (3/4") recording cassette. Records ITU-R BT.601-2 and SMPTE 125M data with a 2:1 compression.
Industry:Entertainment
Data recorders that have been developed using D2 tape offer relatively vast storage of image or other data. Various data transfer rates are available for different computer interfaces. Other computer storage media editing is difficult and images are not directly viewable.
Industry:Entertainment
A serial control interface standard used to operate control registers in picture monitors and video chips. The two-wire system is defined by data and clock signals.
Industry:Entertainment
Frame coded according to an MPEG-1 mode which uses DC coefficients only.
Industry:Entertainment
A point in the transmission where portions of the digital signal can be dropped out and/or inserted.
Industry:Entertainment
A digital tape format that uses 1.25" high-density metal particle tape, running at 57.8 mm/s, to record a video data rate of 50 Mb/s.
Video sampled at 4:2:2 is compressed at 3:3:1 using DCT-based intraframe compression. Two individually editable audio channels are recorded using 16-bit, 48 kHz sampling. The tape can be shuttled and searched up to x32 speed. Digital S includes two cue tracks and four further audio channels in a cassette housing with the same dimensions as VHS.
Industry:Entertainment
A UK forum of technology and service providers created in August 1995 with the objective to speed up the introduction of digital terrestrial TV in the UK. With its focus on implementation aspects, the efforts of the group are seen as an extension of the work done in DVB.
Membership is open to those DVB members who wish to participate actively in the introduction of digital terrestrial TV in the UK.
Industry:Entertainment
A German association that sets standards for the manufacture and performance of electrical and electronic equipment, as well as other devices. DIN connectors carry both audio and video signals and are common on equipment in Europe. (Also referred to as Deutsche Industrie Normenausschuss.)

These are compression algorithms from the Dolby Laboratories. The AC-2 coding is an adaptive transform coding that includes a filterbank based on time-domain alias cancellation (TDAS). The AC-3 is a dedicated multichannel coding, which like AC-2 uses adaptive transform coding with a TDAS filterbank. In addition, AC-3 employs a bitallocation routine that distributes bits to channels and frequencies depending on the signals, and this improves the coding efficiency compared to AC-2. The AC-3 algorithm is adopted for the 5.1-channel audio surround system in the American HDTV system.
Industry:Entertainment
A compression/expansion (companding) noise reduction system developed by Ray Dolby, widely used in consumer, professional and broadcast audio applications. Signal-to-noise ratio improvement is accomplished by processing a signal before recording and reverse-processing the signal upon playback.
