So what does that have to do with the bombing of the World Trade Center? The Port Authority owns the Twin Towers. Furthermore, the Authority's responsibility for the flow of traffic makes it a prime target for future terrorist attempts. In this brief tour (complete with frequencies) of the agencies under the Authority's jurisdiction, the monitor gains an appreciation for the enormous amount of coordination and communications required to keep New York City on the move. Remnants of the Cold War-DXing the Two Koreas 14 By Jeff Chanowitz Both born of the Korean War, Radio Pyongyang and Radio Korea are still battling the cold war in an attempt to influence the Korean people. Outside of that, their styles have nothing in common. Recent showdowns between the US and North Korea have brought this area of the world back into the public eye. It's a good time to tune in these two voices of a divided people. Blue Ribbon Scanning at the State Fair 18 By Allen Cole In some places it's called the State Exhibition, and among the harvest of crops and livestock, there is also an exhibition dear to the heart of the scanner listener. Displayed in full view are all sorts of radio communications. The challenge is to find as many as possible within a week, because next year much of it will be new all over again.

It provides a narrative overview of progress and impact between April 2010 and March 2012 of the DFID funded Policy and Research Programme on the Role of Media in Development, building on an earlier report submitted for activities carried out between April 2010 and March 2011. In 2006 the Department for International Development (DFID) allocated £2.5 million over five years for the establishment of a 'Policy and Research Programme on the Role of Media and Communication in Development' to be managed by BBC Media Action (formerly the BBC World Service Trust). The Programme ran from July 2006 through to March 2012, including a no-cost extension. A small additional contribution to the Programme from the Swedish International Development Agency was received over the period (approximately £300,000 over the period 2009- 2012). In November 2011, DFID reached agreement with the BBC World Service Trust (since January 2012, renamed as BBC Media Action) for a new Global Grant amounting to £90 million over five years.

    EXECUTIVE SUMMARY: Worlddmb Global Update Digital Radio Broadcasting Using the DAB Family of Standards Global Overview Digital

    EXECUTIVE SUMMARY: WorldDMB Global Update Digital radio broadcasting using the DAB family of standards Global overview Digital radio is making significant advances across Europe with national services now firmly established in the UK, Norway, Switzerland, Denmark, Germany and Netherlands – all with coverage levels of over 90%. Recent months have seen several important developments for DAB digital radio: Norway will switch off FM in 2017 Switzerland has announced its plans for DSO (Digital Switchover) between 2020 and 2024 In Germany, following public broadcaster ARD’s long term commitment to DAB+ in November 2014, the Ministry for Transport and Digital Infrastructure has made clear its strong support and has established a new cross-industry Steering Board to drive forward the adoption of digital radio The UK has launched a major programme to build out national and local DAB coverage, and the licence for a second national commercial multiplex has been awarded, with up to 15 new stations on air in early 2016. Denmark has issued a clear roadmap for digital radio, with a transition to DAB+ by end 2016 and a decision on DSO when 50% of listening is digital The Netherlands has seen the launch (Sept 2013) and strong marketing of national DAB+ services. The next phase of development takes place in 2015 with the launch of regional services. In Italy, in March the regulator AgCom issued licences in three new regions; the coverage of national services is being extended in the South of Italy and Sicily and a plan of frequencies for local digital radio in 40 new regions has been published and AgCom will most likely publish the rules to extend DAB+ services in the new local areas by this summer.

    Chapter 4 South Africa: the Internet Wars

    Negotiating the Net 4/1/2005 - 1 – ________________________________________________________________________ CHAPTER 4 SOUTH AFRICA: THE INTERNET WARS Introduction It was an eleven page fax, unsigned, with a Telkom cover sheet, addressed to ISPA, the Internet Service Providers Association. And it confirmed their suspicions. Things were coming to a head. Only a few days previously, on 11 June 1996, Telkom, South Africa’s giant, state-owned telecommunications monopoly on whose networks the internet and e-mail traffic of the entire client base of the ISPs depended, had finally entered the fray. The months of informal pilot testing, which the various private sector ISPs had anxiously been monitoring, had ended. A major new ISP for them to contend with had officially been launched. SAIX, the South African Internet eXchange, was now out there, in their market. Since Telkom's pre-commercial testing had begun on 1 October of the previous year, they and the other ISPs had talked of little else. An ISP operated by the incumbent could mean no-holds-barred competition for clients (particularly the profitable corporates, whose leased lines were rented from Telkom, making the telephone monopoly privy to their entire client database), including cross-subsidies and predatory pricing. Already many of them knew of informal approaches to their own clients - and the carrot of cheaper prices. Five ISP representatives had met to discuss the growing threat - Dave Frankel of Internet Solution, Jon Oliver of GIA, Mark Todes of Internet Africa, Steve Corkin of Sprint, and Internet activist Ant Brooks. With the support of other ISPs, they had planned the formation of an Internet Service Providers Association.

    ATVOD Working Group on Access Services (WGAS)

    1 ATVOD Working Group on Access Services (WGAS) Report prepared by Nick Tanton Introduction The perceived ease with which viewers can now get access services with linear TV in the UK 1 makes it hard for users/customers to understand why on-demand services generally lag behind in accessibility. The end-to-end chain (content acquisition, versioning, scheduling, delivery and presentation) for on-demand generally differs substantially from that of linear TV. Some processes are (or could be) the same or similar whilst others are not; some also may apply to one on-demand service provider but not to another. In particular the species (and sometimes generational variants) of end-user equipment are diverse and some may not have been designed a priori with accessibility in mind. For on-demand content there are no insuperable barriers to providing subtitles for Hard-of-Hearing people or Audio Description for Blind and Partially Sighted users. However there are various practical technical and commercial challenges which a regulator or service provider may need to recognise and to address if these access services are to be made available in a realisable and usable form to the end-user. For any particular service provider, the mix and impact of these challenges depends on the delivery platform(s) on which they have a presence, their role within a particular delivery chain and their business model. The content of this report represents a distillation of understanding from within the ATVOD Working Group on Access Services (WGAS) and input from individual companies who have participated in those discussions.
