Digital recording

View this topic in
In digital recording, the analog signal of video or sound is converted into a stream of discrete numbers, representing the changes in chroma and luminance values (video) or air pressure through time, thus making an abstract template for the original sound or moving image. Beginning in the 1980s, music that was recorded, mixed and mastered digitally was often labelled using the SPARS code to describe which processes were analog and which were digital.

A New DVTR Coding Scheme For HDTV Recording And High-quality Variable Speed Playback

D. L. McLaren; A. Gersho IEEE 1993 International Conference on Consumer Electronics Digest of Technical Papers, 1993

First Page of the Article ![](/xploreAssets/images/absImages/00697526.png)


Hybrid Heads and Recording Analysis

T. Goto; T. Kabashima; Y. Nose; S. Osada IEEE Translation Journal on Magnetics in Japan, 1987

A hybrid head employing a high saturation flux density material on one gap surface and low saturation flux density material on the other was studied. Compared with the values for normal heads, the hybrid head had about 1.4 times the value of the maximum magnetization gradient on the recording media and its magnetization gradient half-width was significantly less. These results ...


Low Power Discriminators With Input Offsets Correction For Fast Multichannel Recording ASIC

P. Grybo; M. Idzik; P. Maj; K. Swientek Proceedings of the International Conference Mixed Design of Integrated Circuits and System, 2006. MIXDES 2006., 2006

Multichannel ASIC for digital X-ray imaging requires one or more discriminators in each recording channel. The critical parameters of these discriminators are low power consumption and low offset spreads from channel to channel. In the readout electronics dedicated to work with high rates of input pulses the charge sensitive amplifier, filter stages and discriminators are often DC coupled. Such approach ...


On Viterbi detector path metric differences

A. Vityaev; P. H. Siegel IEEE Transactions on Communications, 1998

This letter continues the investigation of methods for computing exact bounds on the path metric differences in maximum-likelihood sequence detectors based upon the Viterbi algorithm. New upper and lower estimates for these bounds are presented and recast in terms of a collection of linear programming problems. These estimates improve upon previously proposed linear programming bounds. The estimates are applied to ...


Formation and Photographic Properties of Selenium-Tellurium Particle Migration Electrophotographic Film

M. C. Tam; P. S. Vincett IEEE Transactions on Industry Applications, 1983

The formation and photographic characteristics of a particle migration electrophotographic film are described, consisting of a monolayer of photosensitive Se-Te particles embedded just below the surface of a softenable matrix polymer coated on a conductive transparent substrate. Unlike a similar film using amorphous Se, known as Xerox0 dry microfilm (XDM), the Se-Te film is essentially panchromatic. The effects of applied ...
