Up until the Olympics open in Beijing in August, the broadcasts are available in the rest of the host cities: Tianjin, Shanghai, Shenyang, Qingdao, Qinhuangdao and Guangzhou and Shenzhen, the industry sectors. China plans to deploy the infrastructure of the country by 2010.HDTV emissions will also be available through mobile devices. Intel, in collaboration with Legend Silicon has developed the Intel Centrino processor dedicated to the Chinese reception of television. In June, should laptops from manufacturers, allowing users to view live broadcasts of the Olympics movement in high-definition standard. These products will be Lenovo, HP, Asus, Sony, Samsung and Toshiba for Chinese market.Dual TH-TV digital terrestrial DMB (Digital Multimedia Broadcasting - Terrestrial / Handheld), adopted in China is a great development of the previous rules, to distribute the TV programs for home and different mobile TV receivers, both SDTV and HDTV resolutions.
Among the European DVB-T, the American ATSC and Japanese ISDB-T and DMB-TH China, the latter is the most advanced standard.
It is based on TDS-OFDM (Time Domain Synchronous - Orthogonal Frequency Division Multiplexing) modulation, which is a development of OFDM is used in DVB-T, and much more complex, such as ATSC (8VSB).
The new technique allows to apply the modulation (in the same way regular OFDM) multi-channel transmission, which is necessary for the wide dissemination of the data flows, especially for HDTV. Advanced TDS-OFDM modulation to improve the transmission parameters of the field through time division.
The Oriental Pearl Tower - the third highest tower in the world. Tower of television programs for people in the region of Shanghai.
3D HD - TV in three dimensions. Korean Hyundai concern now is the introduction of 46-inch television to watch 3D images in HD resolution. Viewers should use special glasses. Television is another 3D display market, but for the first time, with the support of a proper distribution of the signal. Japanese cable TV - BS11 - provides programs in the short (10 minutes), which allow users to feast your eyes on the third dimension. TV costs about $ 4800.
3D HD
The concept of generation of moving images in three dimensions has been known for more than a hundred years.
To create a sense of depth tree size, the brain of the viewer must be two images, left and right eye. Images can be recorded simultaneously by a special arrangement of two cameras, or generated by computer using appropriate software.
3D displays can be divided into two main groups - those that require the use of special glasses and without glasses. "The pioneer" without glasses "solutions Sharp - In 2002, the company has developed the technology using a special filter placed in front of the screen, called parallax barrier, that the diversification of the images displayed by the left and 'right eye.
The method for generating images by computer, has been used by Philips (WOWvx). The same method to create 3D images has been used almost from Samsung and Mitsubishi.
Samsung DLP TV is equipped with software and glasses, which can convert standard video in almost 3D images. Similar technology is available in the Mitsubishi LaserVue TV.
