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. (

An HDTV compression scheme for production-quality recording and high-performance shuttle operation

McLaren, D.L.; Gersho, A. Consumer Electronics, IEEE Transactions on, 1993

A novel scheme is proposed for the efficient coding and compression of high- definition television (HDTV) sequences for recording on digital video tape. The scheme achieves a constant 8:1 compression ratio by exploiting both intraframe and interframe compression techniques and removing both statistical and psychovisual redundancies during the coding process. However, a perceptually lossless image quality is still maintained after ...

Acquisition and Processing of Phase Information with Digital Holography

Xiufa Song; Baoqun Zhao; Hehua Xu Information Engineering and Computer Science, 2009. ICIECS 2009. International Conference on, 2009

Digital holography is a digitized holography. The quantitative phase reconstruction is the unique advantage of digital holography. The recording and numerical reconstruction of digital hologram was analyzed. An off-axis lensless Fourier holographic setup and an off-axis Fresnel holographic system with pre-magnification were built. The phase aberration of the two types systems were analyzed and compared. A phase reconstruction method based ...

The pen-computer interface based on force tablet: active information acquisition for human-computer-interaction

Fei Shen; Le Kang; Bing Fang; Zhongcheng Wu Information Acquisition, 2005 IEEE International Conference on, 2005

The use of pen as an effective communication interface to computer becomes an active research area in recent years. However, the lack of complete solutions for interchange between platforms has hampered its application as no efficient device can record the entire procedure of human handwriting behavior. In this paper, we design a force tablet (F-tablet) for human-computer-interaction (HCI), which can ...

Digital Recording of Electrocardiographic Data for Analysis by a Digital Computer

Taback, L.; Marden, E.; Mason, H.L.; Pipberger, H.V. Medical Electronics, IRE Transactions on, 1959

A corrected orthogonal 3-lead system has been used to record electrocardiograms directly from patients at Veterans Hospitals, using three FM channels of magnetic tape. A pilot facility has been designed and assembled by NBS to permit a medical technician to inspect these on an oscilloscope and select a significant cardiac cycle. This is automatically sampled at millisecond intervals and the ...
