“…In the upgraded version, DAB+, from 2007 [8], [9], the original Audio Codec MPEG-1 Audio Layer 2 is replaced by a new, significantly more effective coding called AAC (Advanced Audio Coding) [9], [10], [11]. AAC belongs to a family of so-called transform codecs operating in the frequency domain using some type of time-frequency domain transformation (modified discrete cosine transform (MDCT), Fast Fourier transform (FFT) or other).…”

This paper describes the complex experiences and the results of the Digital Audio Broadcasting (DAB+) implementation in the conditions of the Czech Republic. It analyses the background of the EUREKA 147 program, its targets, and to what extent they were reached. The main focus is concentrated on the evaluation of the real steps which had to be done during the implementation process before the first regular broadcasting could be started and the difficulties encountered. The key point became experimental broadcasting "DAB Prague". It demonstrated the advantages of this new platform and gave the opportunity to test its functions and physical behavior in real conditions, under the different parameter settings. The important issue is the allocation of the band III by the National Regulatory Authority and the capacity of DAB+ multiplexes. The paper also demonstrates the experience from the setup of the DAB+ headend. It describes the content solution in context of using non-entropic audio coding, setting the codec algorithms and the way to use accompanying multimedia services. The results of the tests and measurements presented in this paper were used in the real project of the regular nationwide DAB+ network.

“…Finally, audio-based applications (including broadcast radio) are witnessing innovation attempts in terms of analog-to-digital conversion (e.g., [24]), location-aware content consumption (e.g., [35]), hybrid delivery models that combine the broadcast signal with a per-listener, non-linear OTT channel (e.g., the HCR approach), listener notifcation (e.g., [50]), the use of chatbots to automate textual interaction with listeners (e.g., [12]), the use of voice interaction and smart speakers (e.g., [8]), the use of synthetic voices in radio programmes (e.g., [51]), and data-driven visualisations like charts to graphically augment the audio signal (e.g., [3]).…”

This paper demystifes listeners' wishes with respect to broadcast radio innovation (with a specifc focus on radio-mediated music consumption). Our study encompasses an ideation workshop with radio experts, an exploratory survey and a mixed methods empirical evaluation. The empirical evaluation uses two concrete concepts (i.e., letting listeners on-the-fy replace radio content with preferred content and fostering participatory radio production by involving listeners as radio content curators) as a lens to zoom in on the questionable desirability of radio innovation. It is learned that a signifcant consumer group exists who will stay loyal to broadcast radio even if it does not evolve substantially, whereas others need disruptive incentives to start listening to radio (again). From our results we distill design recommendations to educate the radio production community about how best to approach radio innovation. CCS CONCEPTS• Information systems → Multimedia streaming; • Humancentered computing → Laboratory experiments; User studies.

“…Later on in 2017, a study concerning the difference in DAB and DAB+ broadcasting was carried out [28]. What is worth mentioning is that the author utilized his own multiplex that was particularly designed and launched in three different configurations for the purpose of this test.…”

The process of digitizing radio is far from over. It is an important interdisciplinary aspect, involving Big Data and AI (Artificial Intelligence) when it comes to classifying and handling content, and an organizational challenge in the Industry 4.0 concept. There exist several methods for delivering audio signals, including terrestrial broadcasting and internet streaming. Among them, the DAB+ (Digital Audio Broadcasting plus) system is one of the leading standards of terrestrial digital radio transmission. Compared with analog FM (frequency modulation) radio, it is more bandwidth efficient and offers greater possibilities when it comes to delivering content and forming an ensemble and multiplex. Currently, many countries worldwide, particularly European States, are still making adjustments in order to perform an efficient switchover from analog FM to digital DAB+ radio. This paper presents the current situation of the digital radio market as well as the results of a subjective quality evaluation study and questionnaire concerning broadcasting in both digital and analog techniques. It involves radio programs, transmitting both speech and music signals, simulcasted in DAB+ and FM standards. It also presents the development of the national multiplex. The results of this study may help both researchers and scientists as well as policy makers and professionals active in the field of broadcasting and electronic media and not to mention the consumption of multimedia content.
