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.

Multicenter validation study of an easily applicable cybernetic prototype device that assesses electrocardiographic abnormalities

Schweizer, M.W.F.; Jooss, M.; Gillessen, W.; Manske, E.; Soula, A. Computers in Cardiology, 1999, 1999

A newly developed digital prototype electrocardiographic device (CardioScanTM) for assessment of electrocardiographic abnormalities was validated in a multicenter study. Recordings from the test device and digital 12 channel electrocardiograms (ECG) were performed at rest for 289 in- and outpatients at three study centers. Sensitivity and specificity of the test device for the correct detection of abnormal ECG were calculated by ...


A Brain Implantable Microsystem with Hybrid RF/IR Telemetry for Advanced Neuroengineering Applications

Yoon-Kyu Song; Patterson, W.R.; Bull, C.W.; Borton, D.A.; Yanqiu Li; Nurmikko, A.V.; Simeral, J.D. Engineering in Medicine and Biology Society, 2007. EMBS 2007. 29th Annual International Conference of the IEEE, 2007

A prototype cortical neural interface microsystem has been developed for brain implantable neuroengineering applications, featuring hybrid RF (radio- frequency) inductive and IR (infrared) optical telemetries. The system is aimed at neural recording from primates by converting cortical signals to a digital stream of IR light pulses, while acquiring clock signal and electrical power through RF induction. The implantable unit employs ...


Training a learning vector quantization network for biomedical classification

Anagnostopoulos, C.; Vergados, D.D.; Kayafas, E.; Loumos, V.; Theodoropoulos, G. Neural Networks, 2001. Proceedings. IJCNN '01. International Joint Conference on, 2001

A competitive learning vector quantization (LVQ) neural net (ANN) was trained to identify third stage parasitic strongyle larvae from domestic animals on the basis of quantitative data obtained from processed digital images of larvae. Various novel quantitative features obtained from processed digital images of larvae were tested whether they are variant or invariant to the shape taken by the motile ...


A transport stream processing LSI for HDD recording and playback of HDTV

Nagata, H.; Yamada, M.; Sakamoto, N.; Sakurai, M. Consumer Electronics, 2001. ICCE. International Conference on, 2001

This paper describes a transport stream control LSI for digital HDTV receivers with HDD recording capability. A high performance HDD playback function using the partial transport stream is realized by a special designed RISC processor and the bitrate control algorithm in this new LSI


Exposing digital forgeries by detecting traces of resampling

Popescu, A.C.; Farid, H. Signal Processing, IEEE Transactions on, 2005

The unique stature of photographs as a definitive recording of events is being diminished due, in part, to the ease with which digital images can be manipulated and altered. Although good forgeries may leave no visual clues of having been tampered with, they may, nevertheless, alter the underlying statistics of an image. For example, we describe how resampling (e.g., scaling ...
