Audio for Digital Television
Audio is an area in television broadcasting and production that causes apprehension with some engineers because of its complexity and the care needed to get it right in design, installation, and operations. With the transition to digital television (DTV), there is a new level of uncertainty because the requirements for audio are far more advanced and complex than before. Yet digital audio provi...
متن کاملDigital Terrestrial Television Broadcasting (DTTB)
A report on the digital terrestrial television broadcasting system (ISDB-T: Integrated Services Digital Broadcasting-Terrestrial) was presented to the Minister of Post and Telecommunication by the Telecommunications Technology Council (TTC) in May 1999 after the largescale field trials conducted by the Association of Radio Industries and Businesses (ARIB). At the ITU-R Study Group 11 Meeting in...
متن کاملA Digital Audio Broadcasting System
T h e audio quality, robustness and complexity issues of a novel mobile digital audio broadcast (DAB) scheme a re addressed. T h e audio codec is based on a combination of subband coding (SBC) and mult ipulse excited linear predictive coding ( M P L P C ) , where the bi t allocation is dynamically adapted according t o both the signal power in different subbands and a perceptual hearing model. ...
متن کاملWetterdatenübertragung mit Digital Audio Broadcasting
Interaktive und dynamische Darstellungen von Wetterprognosen sollen in Zusammenarbeit mit der Digitalradio-Nord GmbH für mobile Endgeräte verfügbar gemacht werden. Wir geben daher zunächst eine kurze Einführung, wie eine dynamische und interaktive Darstellung einer Wetterprognose aussehen kann. Hauptproblem für die Darstellung auf mobilen Endgeräten ist die Datenübertragung. Als Übertragungsweg...
متن کاملDigital Audio Bit-rate Reduction for Broadcasting
The bit rate of a single channel of high-quality digital audio may now be reduced by up to 90% using so-called 'perceptual coding systems' with minimal effects on sound quality. Such systems form the basis of proposals for digital audio broadcasting (DAB), this being the subject of the Eureka 147 programme, and they offer the possibility for extending the storage times available from digital re...
