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. (

Digital video recording

Masuo Umemoto; Eto, Y.; Fukinuki, T. Proceedings of the IEEE, 1995

Through mutual technology transfer between consumer and professional video recorders, the last 20 years has witnessed a rapid evolution from analog to digital recording. Each new digital videotape recorder (VTR) uses different channel coding. This implies that improving the recording density involves the development of new channel-coding schemes together with evolutionary magnetic tapes and heads. As a result, professional digital ...

Data compression systems for home-use digital video recording

de With, P.H.N.; Breeuwer, M.; van Grinsven, A.M. Selected Areas in Communications, IEEE Journal on, 1992

The authors focus on image data compression techniques for digital recording. Image coding for storage equipment covers a large variety of systems because the applications differ considerably in nature. Video coding systems suitable for digital TV and HDTV recording and digital electronic still picture storage are considered. In addition, attention is paid to picture coding for interactive systems, such as ...

New approaches to digital evidence

Maurer, U. Proceedings of the IEEE, 2004

Digital evidence, such as digital signatures, is of crucial importance in the emerging digitally operating economy because it is easy to transmit, archive, search, and verify. Nevertheless, the initial promise of the usefulness of digital signatures was too optimistic. This calls for a systematic treatment of digital evidence. The paper provides a foundation for reasoning about digital evidence systems and ...

Shedding light on the future of SP for optical recording

McLaughlin, S.W. Signal Processing Magazine, IEEE, 1998

Optical recording has lagged behind magnetic recording in two key areas: writable/erasable/rewritable media and density gains from advanced signal processing. While there are some writable optical-disk products available, their writing capability pales in comparison to magnetic recording. A great deal of research and development in writable/erasable/rewritable optical media continues and we address this in the article. Of particular interest is ...

Partial-response coding, maximum-likelihood decoding: capitalizing on the analogy between communication and recording [History of Communications]

Schwartz, M.; Kobayashi, H. Communications Magazine, IEEE, 2009

Signal processing and coding technology for digital magnetic recording is the core technology of the channel electronics module in a hard disk drive (HDD) that processes signals read from magnetic media. In this historical review I focus on what is now widely known as partial-response, maximum-likelihood (PRML) technology, which takes advantage of the inherent redundancy that exists in signals read ...
