South Africa is scheduled to migrate all of its terrestrial television signals from analogue to digital by June 2015. In 2007, the South African Department of Communications (DoC) called for the switchover to digital terrestrial television (DTT), using the Digital Video Broadcasting-Terrestrial (DVB-T) transmission standard, to begin in November 2008 and be complete just three years later, with an analogue switch-off on 1 November 2011. This ambitious plan for a rapid three-year migration is currently in disarray. At the time of writing in October 2010, household migration to DTT has not begun, and there are multiple uncertainties: the DoC is considering replacing the DVB-T transmission standard with Integrated Services Digital Broadband-Terrestrial; the DTT set-top box specifications are not yet finalized; and the government's first 'Digital Dzonga' advisory body has been disbanded by the Communications Minister and is being replaced by new appointees. Other key stakeholders in the migration, the public broadcaster (the South African Broadcasting Corporation) and the state-owned signal carrier (Sentech), are in financial and management disarray. The regulator the Independent Communications Authority of South Africa has effectively ruled that the earliest analogue switch-off could occur would be in 2013, and it now appears that even the June 2015 International Telecommunication Union switchover deadline may be difficult to meet. The authors consider the possible consequences of these events.

Purpose Digitization of terrestrial television enables government to reallocate a portion of spectrum to satisfy the 5G low-band spectrum demand. To accelerate the digitization process, the Indonesian Government has distributed digital terrestrial television (DTT) decoders for households in several DTT trial areas so that the recipients are able to experience DTT broadcasts on their analogue television. To ensure that the DTT is adopted sustainably, this study aims to provide evidence-based policy recommendations by first understanding underlying factors of the intention to purchase a new DTT receiver, either a new DTT decoder or an integrated digital television (DTV).Design/methodology/approach This study uses 2018 survey data collected by Badan Aksesibilitas Telekomunikasi dan Informasi. The samples consist of 433 DTT decoder recipients in nine DTT trial locations in Indonesia. Two logistic models are used, one model for the DTT decoder and the other for integrated DTV. The two models have identical predictors, including respondents' demographics, television media use, technology cluster and DTT-related factors as innovation attributes.Findings The results indicate that the two models share some relevant variables but varying in sign and magnitude, namely, respondents' geographical location and the DTT picture and sound quality. The results also show that pay-television subscription, TV viewing and the difficulty of using the DTT decoder are other factors significantly associated with the intention to purchase a new DTT decoder.Research limitations/implications This study has several limitations. First, the coefficients of determination are low, indicating that more independent variables should be included in the estimation models to obtain better insight about DTT adoption so that a better policy can be stipulated accordingly. Second, even though most of the predictors and proposed recommendations can be applied in general, all respondents of this study were DTT decoder recipients. Thus, future research can be more inclusive. Third, this study is designed based on the correlational model. This might cause the inability of the results to provide a conclusive direction of the relationship.Practical implications Demand-side and supply-side approaches are proposed to drive sustainable adoption of DTT, including the provision of subsidy or free DTT decoder for low-income households, increasing competition intensity among DTT devices manufacturers and distributors by allowing more players enter the Indonesian market, driving nationwide DTT infrastructure deployment and stipulating a national standard of the DTT devices.Originality/value This study enriches the understanding of the DTT adoption by incorporating geographical location variables for the proxy of infrastructure availability into the diffusion of innovation model, which has never been addressed by previous studies in the context of DTV adoption. In addition, this study focuses on a specific context in which all samples are free decoder recipients so that they have the same chance to experience DTT broadcasts.

Digital television in Germany is not really the subject of national-level policy. Initiatives are left to the broadcasters and to the 'Landesmedienanstalten', the fourteen bodies that regulate broadcasting in each of Germany's sixteen Lander (regional states). The explanation for this lies in the history of German broadcasting. Government attempts to strengthen Germany's role in the electronics industry during the 1970s, 1980s and 1990s were broadly unsuccessful. When digital television became a possibility, the broadcasters and the state-level regulatory bodies took the initiative, with Berlin pioneering digital terrestrial switch-over. Analogue terrestrial switch-off was completed in 2008, but terrestrial reception accounts for a very small proportion of households, and cable and satellite remain a mix of analogue and digital technology. Today the major players have their commercial strategies, but the national government has given up on media policy, and the electronics sector has mostly disappeared.

This study aims at unveiling the difficult transition to digital terrestrial television (DTT) in Italy. After sketching the theoretical framework, the article focuses on how the Italian government, communications regulatory authority AGCOM and the European Commission (EC) have shaped the current digital framework in Italy. The findings indicate that Italian DTT policies are deeply rooted within their national context and that Italian policy-makers failed to secure a solution to the abiding lack of pluralism of the Italian broadcasting market. During the transitory period, the Digital Broadcasting Act of 2001 gave the two main broadcasters - RAI and Mediaset - an unfair advantage in experimenting digital terrestrial transmissions as well as trading for frequencies and installations. Likewise, the more recent new final National Plan for the allocation of frequencies does not seem to guarantee a plurality of operators in the new digital market.

The reliability and efficacy of indoor reception of 8VSB digital terrestrial television (DTV) in four major U.S. cities was studied in an initial field measurement survey program and a subsequent data capture and processing program. Measurements from the initial survey identified problem sites for reliable DTV reception using currently available 2nd generation DTV receivers. Subsequent field dual channel data captures made at the identified problem sites provided data for testing and verification of new antenna diversity receiver algorithms destined for future generation DTV receivers. From data captures at selected problem sites of sufficient signal strength, but where currently available 2nd generation DTV receivers failed, it was found that in 70% of the cases DTV reception performance was satisfactory when using new antenna diversity receiver algorithms. These measurements and data captures corroborate the claim that the VSB DTV indoor reception problem may be less severe than implied from surveys using less advanced current 2nd generation receivers with a single antenna. For sites with severe multipath, 8VSB DTV reception could be potentially superior to NTSC, which would experience an unwatchable picture.

At a preparation of the transmission equipment for digital terrestrial television, there is a requirement to try moving an equipment investment back by means of a broadband antenna simultaneously to be able to transmit the channel that frequency departed. So far, though twin loop antenna had been much used as a transmission antenna for UHF, it was a narrow band and many kinds (9 kinds). We have developed a broadband 4L-type twin loop antenna(24U) which was able to cover UHF with 2 kinds.

This study employed Rogers' model to compare the diffusion of digital terrestrial television with the diffusion of digital cable in Taiwan. A telephone survey, which yielded 753 valid questionnaires, was conducted to collect data. The results of this study show that the factors affecting the intention to adopt digital terrestrial television differed widely from those affecting the intention to adopt digital cable. The diffusion of digital cable was discovered to be generally congruent with the prediction of Rogers' model, while the diffusion of digital terrestrial television was not. This second finding reveals a limitation in Rogers' model, namely, its alleged pro-innovation bias. It may be that the respondents in this study looked favorably on digital cable because they considered it, and not digital terrestrial television, to be an inevitable technology. Furthermore, this study found that awareness played an important role in respondents' adoption of digital television. This study therefore suggests that, to accelerate digital conversion, Taiwan's government should establish policies to educate people about digital television.

The introduction of the digital terrestrial television (DTT) in Portugal has developed slowly and hesitantly for over a decade. Technological uncertainties and the absence of a clear business model contributed for a sluggish development of the process. Portugal is today one of the European countries with fewer DTT channels. However, and differently from other EU states, the Portuguese authorities have played a double role in the process: as a legislator/regulator and as a protector of the biggest telecommunications operator in the country, Portugal Telecom (PT). In the Portuguese case, the public sector (not always overt) position was based on a symbiotic relationship between the State and PT (now the holder of the frequency use rights for the provision of the DTT service). This symbiosis was made possible through golden shares that were held by the State in PT, since the privatization of the company. The interplay between the State and PT regarding the establishment of the DTT in Portugal is the main focus of this article.
