This paper presents the field trial results of digital audio broadcasting (DAB), DAB+ and terrestrial-digital multimedia broadcasting (TDMB) audio systems to provide useful information about each digital radio broadcasting standard. Although the all methods are representative digital radio broadcasting standards based on Eureka-147, they have different parts from each other. This field trial re...

Digital Media Technologies offer enhanced multimedia signal broadcasting and description of the signal on content. Digital Audio Broadcasting (DAB) is a media standard with extended multimedia capabilities, offering novel services to users worldwide. Each digital broadcasting standard though, cannot be separately viewed from the development of Internet radio broadcasting. In this paper we intro...

Since digital radio broadcasting techniques can give highly enhanced performance and quality (e.g. CD like audio quality, single frequency network, slide show, etc), many countries pay attention to converting their analog radio broadcasting services into digital services. In Korea, to digitize radio broadcasting service, various trials have been executed since 2009 [1]-[2]. This paper deals wit...

In the past, digital transmission of video and audio has required a broader frequency bandwidth than analog transmission to transmit the same information. Recent progress in source coding technology for video and audio, however, has made it possible to reduce the bit rate while keeping the quality deterioration to a minimum. The frequency bandwidth required for digital transmission has conseque...

As broadcasting environments change rapidly to digital, user requirements for next-generation services that surpass the current HDTV service quality become more demanding. The next-generation of broadcasting services will change from HD to UHD and from 5.1 channel audio to more than 10 audio channels, including a height channel for a high quality realistic broadcasting service. In accordance wi...

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. ...

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...

China digital audio broadcasting in FM band (commonly referred to as CDR) is a newly released digital audio broadcasting standard (GY/T 268-2013) which operates in the FM-band (87MHz to 108MHz) in China. This report introduces this standard in English for the first time which is based on an official version written in Chinese, including multiplexing, frame structure, channel coding and modulati...
