As general manager, president, and chair of the board of RCA, he strongly shaped the future of television; also the David Sarnoff Research Center named for him, currently part of SRI International, formerly RCA Laboratories, home of ACTV research and development.
Industry:Software
Number representation system used for signed binary integers in which the negative of a number is obtained by complementing it. The leftmost bit becomes the sign bit, with 0 for plus, 1 for minus.

The goal of the Open MPEG Consortium is to “create a single API for the playback of MPEG-1 titles under Windows and DOS.” The consortium has developed the MPEG Multimedia Control Interface (MCI) which defines how MPEG boards operate under Windows.
Due to some undefined topics, the MCI specification has not been able to curb incompatibility, but the consortium has later cooperated with the Japanese OMWF group on an enhanced specification.

In traditional painting, paint is applied in layers, and the last paint applied is what is visible. Digitally, the last value placed in a pixel determines its color.

PALplus (ITU-R BT.1197) is 16:9 aspect ratio version of PAL, and is compatible with standard (B, D, G, H, I) PAL. Normal (B, D, G, H, I) PAL video signals have 576 active scan lines. If a film is broadcast, usually 432 or fewer active scan lines are used. PALplus uses these unused “black” scan lines for additional picture information. The PALplus decoder mixes it with the visible picture, resulting in a 16:9 picture with the full resolution of 576 active scan lines. Widescreen televisions without the PALplus decoder, and standard (B, D, G, H, I) PAL TVs, show a standard picture with about 432 active scan lines. PALplus is compatible with standard studio equipment. The number of pixels of a PALplus picture is the same as in (B, D, G, H, I) PAL, only the aspect ratio is different.
Industry:Software
The recording of multiple PCM data streams which are synchronous to a common clock onto multitrack recorder/reproducers.
Industry:Software
The key technology that has allowed under $1000 video capture cards to achieve such high quality levels. With PCI bus mastering, you get perfect audio sync and sustained throughput levels over 3 megabits per second.
Industry:Software
A method of recording digital signals on a disk like a standard vinyl record.
PCMCIA (Personal Computer Memory Card International Association) – A standard format for credit-card size expansion cards used to add storage capacity or peripherals such as modems to a computer.

Short time distortion amplitudes are not generally quoted directly as a percent of the transition amplitude but rather are expressed in terms of an amplitude weighting system which yields “percent-SD.” This weighting is necessary because the amount of distortion depends not only on the distortion amplitude but also on the time the distortion occurs with respect to the transition. The equation for NTSC Systems is SD = at0.67 where “a” is the lobe amplitude and “t” is the time between transitions and distortions. In practice, screen graticules eliminate the need for calculations.
Refer to the figure below. Also see the discussion on Short Time Distortions.
