High Definition and 3D TV Trends
By David Kirk The visual difference between standard definition and high definition 1080-line or even 720-line pictures is rapidly driving the market towards the new de facto standard of high definition, and the latest in display technology doesn’t end there...
2011 was the year in which 1080line ‘high definition’ became the de facto standard definition. 625-line and 525-line are effectively dead, notwithstanding the fact that they look remarkably good when seen on a 40-inch flat-panel display at a typical two-metre viewing distance. Price is the main engine powering this worldwide upgrade. As I write this (early January 2012), the UK starting price of 1920 x 1080 pixel native 40-inch LCD domestic receivers is down to £329 for a Toshiba 40BV701), rising to £479 for a Samsung UE40D5520. The continued expansion of HD broadcasting is obviously dependent on the willingness of channel managers to invest in the necessary infrastructure. This is being hastened by the worldwide migration from analogue to digital delivery. In Britain, the London region is due to switch over in two stages on April 4 and 18. Although the new service will still be primarily 625-line for the foreseeable future, the analogue switch off will undoubtedly encourage many television viewers to explore alternative delivery avenues such as Freesat which offers over 150 channels on a nosubscription basis, including a gradually increasing number of HD channels. NAB 2011 was notable for the positioning of the 4K – nominally a 4,000 horizontal by 2,000 vertical pixel – picture format as a potential successor to the 1920 x 1080 highdefinition standard. 1920 x 1080 is equivalent to a video resolution of two megapixels. The 4K standard is equivalent to eight megapixels and was supported at the show by cameras from ARRI, JVC, Sony and Red, plus a magnificent 3.6 metre wide by nearly 2 metre high 4096 x 2160 pixel plasma screen from Panasonic. Canon has also since declared its support for 4K (see SATIS 2012 show report in the December/ January edition of InBroadcast). What makes 4K important is that it bridges the divide between two megapixel HD and the nominally 32 megapixel UHD (ultra-highdefinition) 8K format which Japanese state broadcaster NHK has proposed as an eventual successor to HD. The research and development department of NHK was the inspiration for the two megapixel standard. NHK will presumably start campaigning for a 512 megapixel standard if or when UHD becomes established. UHD has been criticised in many quarters

Samsung’s latest 3D glasses charge wirelessly

for going beyond the screen-size requirements of any normal household but such comments overlook the fact that the pixel size of modern high resolution displays such as the latest generation of Apple computer monitors has become smaller, producing much higher picture quality for a given screen size. far

3D Channels

Thirty-two 3D broadcast television channels are currently active via terrestrial, satellite or cable delivery: Australia 1, Belgium 1, Brazil 1, Britain 1, Canada 1, Europe 3, Finland 1, France 1, Germany 2, India 1, Israel 1, Japan 2, Mexico 1, Poland 4, Romania 1, South Korea 1, Spain 1, Sweden 1, Turkey 1, USA 6. China is also planning a trial 3D service on its main national network, China Central Television, and regional networks covering Beijing, Tianjing, Jiansu and Shenzhen. The first regular 3D television service was from UK broadcaster Sky 3D which officially started on 1 January 2010. The 3D version of Samsung’s £479 UE40D5520 40 inch LEDbacklit LCD television receiver is model UE40D6100. Price difference is just £50. It is only a matter of time before 3D becomes the default choice for all television displays. 2D sets will then become as hard to find as monochrome. If broadcasters need additional encouragement to invest in 3D, they have it. Owners of 3D-capable displays always have the choice of leaving the glasses off and staying with 2D content until 3D really proves itself. Most currently available 3D displays rely on active or passive polarising filters to assign the left and right optical channels to the
