Digital sound broadcasting system.

A 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. ...

Digital Video Broadcasting

The Digital Video Broadcasting (DVB) Project was founded in 1993 by the European Telecommunications Standards Institute (ETSI) with the goal of standardizing digital television services. Its initial standard for satellite delivery of digital television, dubbed DVB-S, used a concatenation of an outer (204,188) byte shortened Reed Solomon code and an inner constraint length 7, variable rate (r ra...

Digital Video Broadcasting

DVB-S2 is the second-generation specification for satellite broadcasting – developed by the DVB (Digital Video Broadcasting) Project in 2003. It benefits from more recent developments in channel coding (LDPC codes) combined with a variety of modulation formats (QPSK, 8PSK, 16APSK and 32APSK). When used for interactive applications, such as Internet navigation, it may implement Adaptive Coding &...
