This curve is derived from the CCIR 468-curve. Dolby Laboratories proposed using an average-response metre with the CCIR 468-curve instead of the costly true quasi-peak metres used by the Europeans in specifying their equipment. They further proposed shifting the 0 dB reference point from 1 kHz to 2 kHz (in essence, sliding the curve down 6 dB). This became known as the CCIR ARM (average response meter), as well as the CCIR 2 kHz-weighting curve.
Industry:Software
Now part of GE. RCA was once involved in every aspect of television, from camera to receiver, supplying production, transmission, consumer electronic, and CATV equipment, and operating a television network (NBC) and a satellite transmission carrier.
RCA developed the first effective HDTV camera tube, proposed several HDEP schemes ranging from 750 to 2625 scanning lines, and did extensive ATV research at RCA Laboratories (now SRI International’s DSRC).
RCA’s broadcast equipment group no longer exists, Burle is selling its tubes, and its consumer electronics are now part of the Thomson group.
GE has, thus far, retained the satellite transmission carrier (renaming it GE Americom) and the NBC television network, a proponent of the ACTV ATV schemes.
Industry:Software
A time-code system, available on 8 mm and Hi-8 formats only, supported by the thumbs up editor. The code can be added either before or after video recording without affecting the video or audio.
Industry:Software
A type of connector used on all consumer VCRs and camcorders to carry the standard composite video and audio signals. See also Phono.
Industry:Software
A control which matches the signal level monitored in the input position of the output selector switch to that of the signal recorded and played back from the tape.
Industry:Software
CCIR recommendation (standard) for digital component video, equally applicable to 525 and 625 scanning lines, also called 4:2:2. Digital component video is about as close in quality as current 525 scanning line equipment can come to ATV. See ITU-R BT.601-2.
Industry:Software
Ratio of the radiant or luminous flux reflected in the directions delimited by the given cone to the reflected in the same directions by a perfect reflecting diffuser identically irradiated or illuminated.
Industry:Software
The process of supplying an RF signal to several devices simultaneously.
Industry:Software
A Dolby Digital decoder operational mode intended primarily for cable set-top boxes that are connected to the RF (antenna) input of a television set. The dialnorm reference playback level is –20 dBFS and compr words are used in dynamic range compression. Refer to Dynamic Range Compression.
Industry:Software
The process of combining a video signal and/or audio signal with an RF source so the result can be transmitted to a radio receiver, television, or VCR.
