The global digital TV technology solutions to break the pattern of embryonic development

    The terrestrial digital television (DTV) has three standards: the European DVB-T, American ATSC and ISDB-T in japan. ISDB-T standard only before the other parts of Japan, using DVB-T and ATSC standard. But Brazil's recent decision to use Japanese standards, coupled with China to develop its own standards, will affect the global TV industry pattern.

    At present, in addition to the DVB-T standard in Europe, and Taiwan, India, Australia and South Africa and other countries and regions. The standard on the mobile reception performance. ATSC emphasizes the broadcast quality, South Korea, Canada, Mexico and the United States of America use this format. Analog TV Japan by the United States of America in NTSC format, but the digital TV will use its own ISDB-T standard, the standard also consider mobile reception performance and HD radio.

    ISDB-T had no foreign markets. The corresponding TV manufacturers are developing ATSC and DVB-T television. The population of Brazil is the fifth largest country in the world, each year more than 10000000 TV demand. Brazil currently has 70000000 TV in use. The TV system is derived from the European PAL standard PAL-M. According to the latest news, because the Japanese commitment to invest in Brazil semiconductor industry and assist the development of IT industry, Brazil will use the ISBD-T standard. Brazil is the first South American countries announced the DTV standard. But before that, Argentina, Chile, Uruguay and Paraguay have already announced that they will follow the pace of Brazil. This decision Brazil will cause a lot of vibration in South america.

     With the former Japanese television manufacturers blossom everywhere in the world, in the digital TV era, although they are still an important role, but in the flat screen TV, especially TFT-LCD, in addition to Sony and Toshiba, Sanyo, sharp, Panasonic and other traditional manufacturers because of the lack of face plate support, are in a disadvantageous position.

     China is already at the end of 8 officially announced the matters related to digital television standard, focus on using domestic standard. However, the progress of delays, in addition to technical reasons, there are different standards of competition. The two main rival is Tsinghua University Shanghai Jiao Tong University DMB-T standard and ADTB-T standard. Both sides have their supporters, the government department decision-making very cautious.

     But the Beijing 2008 Olympic Games to broadcast HDTV content, so it must be a decision. To the end of 8, finally passed the GB20600-2006 standard, including DTV terrestrial broadcasting system frame structure, channel coding and modulation. The essence of the standard is set DMB-T and ADTB-T standard. Official media reported that the system with single and multi carrier mode, can be in the city (multi carrier) and rural (single carrier) use. But recently the news two systems have substaintial distinction, to invest large sums of money to solve technical problems.

     China has actively developed its own standard is mainly based on two considerations. One is to avoid television royalty, two is to improve the competitiveness of the domestic TV industry. China is now the world's largest producer of TV sets, with an annual output of more than 80000000 part television. The domestic market demand of about 40000000, the rest are sold all over the world. At present, the television in the approximately 400000000. Analog TV broadcast about at the end of 2015.

     Although China is the world's largest TV producer and television market, but the lack of its own technology. In addition to TV industry flat-panel TV evolution, domestic manufacturers due to the lack of upstream of LCD and PDP (plasma TV) panel manufacturer support, competitiveness will be severely weakened. Through the development of private standards, help domestic manufacturers to consolidate the domestic market, with Japan and South Korea manufacturers compete in the future.

     Obviously, the future of TV industry flat-panel TVs world. The short term, flat-panel TV market is mainly Japan, Europe and North america. However, demand in China and the South American market will rise. As China and Japan to adopt its own standard, will help to enhance the overall competitive advantage in their.
