ITU News Issue 4 2004 - From Analogue to Digital Television - The Australian WayRoger G Bunch
1) Australia began researching digital terrestrial television broadcasting (DTTB) in the mid-1980s and decided in the early 1990s to develop DTTB that paralleled the existing analog television structure.
2) In 1998, Australian broadcasters began developing industry practices for delivering standard definition (SDTV) and high definition (HDTV) content for DTTB, specifying quality standards. Transmissions began in 2001 in metropolitan areas and 2003 in regional areas.
3) The development of DTTB in Australia included establishing transmission standards based on DVB-T, developing digital channel plans, promoting consumer awareness of DTTB benefits, and managing interference issues during the transition to DTTB.
The document discusses future scenarios for broadcast spectrum use and technologies. It outlines possibilities for digital television and radio services, including full analog to digital transition or hybrid models. New services like mobile TV and radio are also discussed. The spectrum could be shared between broadcast services and other wireless technologies to provide broadband access. Overall broadcasting is expected to continue evolving to distribute multimedia content across various platforms and devices.

Fixed Satellite Communications are used for multiple applications within government and defense operations. The fixed communication infrastructure is the permanent or semi-permanent satellite link between
headquarters and remote operation sites. In many cases these sites are located in hotspots or remote areas around the world that have no access to terrestrial communication infrastructure.
Why do we need an HD Internet?Presentacio ucaid2002 bArtur Serra
This document discusses opportunities for high-definition (HD) internet among research universities. It describes an HD internet project in Catalonia called i2CAT that transmitted uncompressed HD video over fiber between universities. This included an opera performance transmitted from Barcelona to Amsterdam in 2002. The project demonstrated HD internet is possible but challenges remain in high equipment costs and developing business models. Universities are well-positioned to help create open HD content and lead the development of HD internet if they act as digital media producers rather than just publishers.
Sprint and Nortel Networks were awarded the annual 3G CDMA Industry Achievement Award for their smart antenna trials that demonstrated improved spectrum efficiency and greater voice capacity. The trials used Nortel's Metro Cell platform over a live CDMA network in Ottawa and showed a two-fold increase in voice capacity. The award recognizes innovation that provides flexible and cost-effective solutions to network operators.

- WTON is an annual conference on optical technologies hosted by CPqD, a Brazilian research center. The most recent conference in 2014 had over 150 participants from industry, academia, telecom operators, and research centers.
- CPqD bridges universities developing scientific research and innovative companies seeking new products through technological R&D. As an EMBRAPII unit since 2014, CPqD offers national industry expertise in optical communications technologies including long distance transmission systems, optical transport networks, access networks, and optical sensing systems.
- The upcoming IV WTON conference in 2015 will cover topics such as high-capacity networks, flexible networks, integrated photonics, and the Internet of Things. Participants are invited to visit
During 2015, Ofcom UK licensed and co-ordinated a trial of small scale DAB . The report concludes that the trials were generally highly successful and achieved their three objectives.
The document summarizes a report on trials of small scale DAB radio broadcasting in the UK. Small scale DAB uses less expensive equipment than existing DAB services, making it more suitable for smaller radio stations. Ofcom oversaw 10 trial licenses across the UK in 2015-2018 to test the technical viability and market potential. The trials involved providing standardized transmission equipment to licensees and showed that small scale DAB worked reliably. Over 70 radio stations participated across the 10 areas. The report concludes small scale DAB is technically sound and there is demand for wider rollout to more areas.
