National Engineering Lab of digital TV Yang Professor 25, knowing that as China's own intellectual property rights of terrestrial digital TV transmission standard (DTMB standard) in the ITU to obtain digital TV standard D system identifiers, DTMB standard is expected to become the fourth international standards.
According to Professor Yang knowing and 25 June, Beijing National Engineering Lab of digital TV reporting on the results, the last two years, DTMB standards in the Chinese mainland, Hong Kong, Macau is used, the establishment of the world's most advanced broadcasting SfN, DTMB user penetration rate has more than 61%, over 200 Terminal products sold on the market. In Cuba, Venezuela, Peru, Ecuador, and other countries and Europe, the United States and Japan in international comparison of similar standards are achieved in testing technology first.
In addition, promotion and application of standard overseas DTMB has also been a breakthrough, to explore a variety of extension model. LAO has already started using standard and DTMB scale commercial, with 3 million DTMB users, plan 2012 complete national analog/digital TV conversion; Cambodia published bulletin announced the adoption of standards; a group of DTMB in Asia, Africa, and La countries DTMB standard intergovernmental negotiations in progress.
Yang, Director of knowing that Beijing National Engineering Lab of digital TV will be based on our digital TV industry needs to continue to study the development of digital TV in the common technology and subsequent evolution of the core technologies that build the front-end and the launch of digital television, chip and receive, transport and network, test and display the four research and development, test and engineering verification platform, sustainable and healthy development for the industry to provide support.
"At the same time we will also continue to promote DTMB standard promotion, digital TV, intellectual property management, new technology assessment, technology and development strategic consulting, and bear the national release and Enterprise delegate technology development and engineering studies, and other tasks. "Yang said knowledge.
It is understood that in the digital television terrestrial, cable and satellite transmission, ground transport, the highest technical requirements. Currently, the ITU has ratified the United States ATCS, European DVB-t and Japan ISDB-P three terrestrial digital TV broadcasting transmission to international standards. Launched in 2006, China DTMB standards, and in August 2007, with the transmission of high efficiency, high anti-interference, channel estimation performance is good and suitable for mobile reception, etc.
