XM radio service is an emerging satellite digital audio radio service suitable for automotive environment, it offers users high-quality radio programs with better signal coverage by adopting communication satellite broadcasting technology. In order to incorporate XM radio function into a digital car audio system based on the embedded system industry standard ITRON, we analyze both software and ...

Audio coding is widely used in application such as digital broadcasting, Internet audio or music database to reduce the bit rate of high quality audio signal without comprising the perceptual quality. In this paper work high quality audio codec at low bit rate using wavelet transform and improvement in reconstructed wave using post filtering has been proposed. The major issues concerning the de...

The paper anticipates that the actions to be taken concerning the Digital Switchover (transition form analogue to digital broadcasting – DSO) in UHF are of strategic importance for the European Member Countries and most candidate ones, as long as DSO arises as a possible and complementary solution towards the deployment of Broadband Access Infrastructures, especially in less favoured regions. T...

Error correction technology, with which the errors that occur during transmission are corrected, is essential when high-quality digital video and audio are to be provided in digital broadcasting The principle of error correction is that the improvement in the reliability of the received information as a result of error correction will more than compensate for the increase in data caused by the ...

A novel method of using the Globalstar LEO constellation to provide 25 channels of digital-quality, audio broadcasting (DAB) to vehicles and homes throughout Australia is described. The low-cost approach will attract broadcasters who want to reach listeners throughout Australia especially in areas of low population density. By adaption of existing satellite radios, transmission systems and the ...

DAB (Digital Audio Broadcasting) is a the European successor of FM radio and it can broadcast besides audio services also other services such as traffic information. In this paper the probability of non-recognized errors in the system is derived for a 8 kbit/s data subchannel using protection level EEP3-A. This is important as data services rely on error-free transmission. It has been shown tha...

Abstract— In OFDM based single frequency networks (SFNs) used in digital audio broadcasting (DAB) and digital video broadcasting (DVB) the received signal can be a superposition of multiple useful and interfering lognormal components. In many cases considerable correlations exist among these components. These correlations are typically neglected in the system analysis. In this paper we show tha...

The Digital Archive of the Hellenic Broadcasting Corporation (ERT) is one of the most important attempts to preserve and disseminate the most valuable audio-visual archive of the Hellenic history and culture as seen and recorded throughout the years by the National Broadcasting Corporation. A usability survey was undertaken in order to evaluate the aforementioned digital archive using Jeng’s us...

A synthetic aperture radar is considered, located on a geosynchronous receiver and illuminated by the backscattered energy of satellite broadcast digital audio or television signals. The principal application of such a passive system could be differential interferometry, since even low spatial resolution coupled to zero baseline would be useful; however, other imaging applications could be envi...
