Australia BROADCAST SITE EMBRACES GREEN POWER Another challenge for broadcasters is how to conserve energy used to power transmission systems. Broadcast Australia may have shown one solution, when it recently upgraded its Mount Owen site to be majority powered by renewable energy. Near Queenstown in Tasmania, the site has been recently upgraded to use site-generated wind and solar power, which together are expected to reliably meet the site’s 8kW power demand for 80%-90% of the time. This will potentially save up to 60MWh of conventional power each year. The experience gained will have far- reaching implications for Broadcast Australia’s carbon footprint for the future, as renewable power options are being considered for a multitude of additional sites.
The Mount Owen site broadcasts a range of national and commercial analogue/digital radio and TV services to the Queenstown and Zeehan area, as well as supporting critical radio communications for local emergency services. As this is a remote facility, providing on-site renewable energy generation was a commercially viable option, compared with the cost of upgrading the mains feed, to enable the broadcast of digital TV to the local area.

DDI DRAWS BIG COMMONWEALTH GAMES AUDIENCE DDI introduced high definition television in the country along with the Commonwealth Games in October. Well over 20 million Indian viewers watched the Commonwealth Games coverage of the national broadcaster, Doordarshan, on each of the first three days of the event. The games were being telecast on five Doordarshan channels. This was the first time in Commonwealth Games history that the event had been broadcast in High Definition digital, also marking a critical milestone for Indian television.
The Basic Feed was generated in HD SDI (16:9 Aspect Ratio) at the Venues. Also the coverage was 4:3 Aspect Ratio protected including ‘Safe’ Graphics output so that Standard Definition (SD) viewers were not deprived of the full details. Audio Signals were in Stereo (L&R), and available as embedded audio-only both at venues and the IBC. The recording format was HDCAM/Hard Disc with a compression kept at a minimum of 125 Mbps. Doordarshan converted 40 transmitters and studios to digital in the Doordarshan network. This included networking of DTT through satellite. (

NHK-BBC SUCCESSFULLY TEST SUPER HI-VISION TV
The BBC sent a Super Hi-Vision TV broadcast of a band gig to Japanese public broadcaster NHK in a successful transmission test of the experimental digital video format. The Super Hi-Vision TV signal has a higher resolution than the current generation of high-definition plasma displays. NHK’s powerful optical data transmitter inside the Super Hi-Vision camera captured a live set and streamed the video at 24Gb/s to a large screen in Tokyo where it was watched by locals.
Super Hi-Vision TV can generate a 7680 by 4320 pixel signal, which no commercial TV can show yet. The highest resolution that current high-definition displays can show, 1920 by 1080 pixels, is only one quarter of the resolution of Super Hi-Vision. The BBC is planning to use the technology in capturing the 2012 Olympics in London and showing the video on test screens. NHK plans to broadcast in Super Hi-Vision by 2020.
