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.

On the use of splitting vectors with zero components for constrained encoder design

Tong Shi; J. Kieffer Communications, 1996. ICC '96, Conference Record, Converging Technologies for Tomorrow's Applications. 1996 IEEE International Conference on, 1996

The state-splitting algorithm is a method for designing an encoder for a constrained system of the type prevalent in digital recording system technology. Traditionally, the starting point of the state-splitting algorithm involves finding a "splitting vector", a vector with positive integer components whose component sum is an upper bound on the number of states of the encoder to be designed. ...


Characteristics of laminated alloy films heads for high frequency recording

K. Saito IEEE Transactions on Magnetics, 1990

Excellent performance of laminated Fe-Si-Al alloy film heads is demonstrated in applications to high-definition VCR and to digital recording. It is emphasized that these results are derived not only from the ring-shaped core geometry but also from the isotropic behavior in the magnetic properties of the sputtered Fe-Si-Al alloy films. The experimental results on the isotropic magnetic behavior are summarized. ...


An analog method for detecting superimposed power line voltage disturbances

H. W. Furst; M. Pigl; J. Baier IEEE Transactions on Instrumentation and Measurement, 1994

Power line monitoring has become increasingly important during the past few years as many failures in sensitive electronic equipment are due to various types of power line disturbances. An analog, low-cost solution for multichannel power line disturbance analyzers which performs a triggering function that detects changes in the voltage waveform is described. The method may also be used for other ...


A new video hard disk system for multimedia program production

This paper reports on a new video hard disk system for real-time recording and playing back of high-quality digital video signals, an important component in the production of multimedia programs at broadcasting stations. The paper clarifies some of the problems associated with the recording of high-quality video signals on a conventional hard disk system designed for storing computer data. It ...


Summarization of wearable videos using support vector machine

Haung Wei Ng; Y. Sawahata; K. Aizawa Proceedings. IEEE International Conference on Multimedia and Expo, 2002

Auto-summarization of video contents has become an important topic following the growing amount of multimedia contents. Researches in this area have shown the effectiveness of low-level video and audio features in categorizing video contents. The use of brainwaves to reflect personal interests is also proven to be practical. In this paper, we model the relationship between audio/video features and brainwaves ...
