Sullo sfondo di tutti questi discorsi aleggiano infine i discorsi sulle politiche di switch-off delle trasmissioni analogiche. Che possono non piacere, ma intanto emergono sempre più frequentemente.
Canada Rules to Allow HD Radio
Dec 27, 2006 9:50 AM
Ottawa - Dec 15, 2006 - The Canadian Radio-Television and Telecommunications Commission (CRTC), the independent, public authority that regulates and supervises broadcasting and telecommunications in Canada, has revised its policy for digital radio broadcasting to consider the HD Radio in-band on-channel (IBOC) system. In its Public Notice CRTC 2006-160, the Commission commented that it would be prepared to authorize services using IBOC technology for the AM or FM bands if the Canadian Department of Industry authorizes services using the technology under the Radiocommunication Act. The commission added that "an expedited process would be adopted for stations that propose to transmit a digital simulcast of their analog service."
Robert Struble, president and CEO of Ibiquity Digital said, "The Canadian Broadcasting Corporation (CBC) began HD Radio testing in September 2006, focusing on transmissions from Toronto and Peterborough, Ontario. Full results have not yet been published by the CBC, but early feedback has been very positive. There are plans to begin testing on MW-AM operations in early 2007."
The ruling also considers other forms of digital radio, including DRM, DMB and DVB-H. The decision to consider HD Radio specifically was based on the advanced stage of the HD Radio rollout compared to other technologies in the United States. Canada has authorized Eureka-147 as a digital radio standard, but the rollout of that technology has not progressed very rapidly and is not seeing wide acceptance.
Korea seeks to adopt digital radio broadcast system
Analogue system has too few frequencies, says Ministry of Information and Communication official

The Ministry of Information and Communication is set to launch a committee to accelerate the application of digital technologies to the nation's radio broadcast system. "Under the current analogue system, newcomers can hardly find available frequency resources. Frequencies have almost been used up, and that's one of the reasons why we are trying to digitalize the whole radio broadcast system," Lee Jung-gu, head of the ministry' broadcasting-satellite division, told The Korea Herald. There are currently 51 radio broadcasters in Korea, including region-based ones. "There are a number of problems left to be examined before converting to digital, including whether to choose Europe's Digital Audio Broadcasting and the United States' In-Band On-Channel as the technology standard." Adopting IBOC will not require the hassle of changing radio sets across the nation to new ones. However, except in its competitive edge, the U.S. technology can not be viewed as a better match than its European counterpart that shares similar technical qualities with Korea's de facto mobile TV platform called digital multimedia broadcasting, Lee said. The digital radio broadcast system is expected to provide CD-level high-quality stereo sound and data services. The new system will also help create fresh market demand and develop related industries. Electronics makers, for instance, will be able to launch digital radio devices into the domestic market.
The committee will consist of three working groups, each discussing technological requirements, legal frameworks and industrial demand. About 18 experts from the industry, academics and research institutes will work for the committee. The committee will focus on the future technology standard, particularly regarding transmission frequency band, sales of capable terminals, re-division of broadcasting areas, legal issues, as well as the most appropriate timing to digitalize the national radio broadcast system. There had been several working groups within the ministry that discussed various related issues ranging from market demand to system specifications, utilization of the existing frequency resources, broadcasting areas, and radio broadcasters' legal status. But it was difficult to narrow down all of the diverse opinions into one, the ministry said.
The new committee will start working in January next year.
