News on November 14th, in view of the wide variety of global terrestrial radio and television standards, which poses serious obstacles to the development of the radio and television industry. The 13 largest radio and television industry organizations in the world recently held a joint meeting for the first time and issued a declaration. International standards, promote industrial development through technology integration. " The industry believes that global unified broadcasting standards may become a trend.
Thirteen major global broadcasting organizations gather in Shanghai
Unlike the global telecommunications industry, which is organized and standardized by the International Telecommunication Union (ITU), the international organizations of the broadcasting industry have always been scattered, and the broadcasting standards of various countries or regions have done their own things. Therefore, it has caused a lot of trouble for broadcasting equipment manufacturers and terminal manufacturers. Seeking dialogue between the broadcast and television industries of various countries around the world has always been an urgent need for the development of the global broadcast and television industry.
It is reported that two or three days ago, 13 global broadcast industry organizations held the first "Global Future Radio and TV Summit Forum" in Shanghai. The 13 broadcast and television industry organizations include the American Advanced Digital Television System Committee (ATSC), the Canadian Broadcasting Corporation (CBC), the Canadian Communications Research Center (CRC), the European Digital Video Broadcasting Organization (DVB), the European Broadcasting and Television Union (EBU), South Korea Institute of Electronic Communications (ETRI), Brazil TV Globo (TV Globo), Institute of Electronics and Electrical Engineers (IEEE), National Association of Radio and Television (NAB), China National Engineering Research Center for Digital Television (NERC-DTV), Japan Radio Television Association Institute of Science and Technology (NHK-STRL), American Public Broadcasting Television (PBS) and Brazilian Television Engineering Association (SET).
The meeting was initiated by the China National Engineering Research Center for Digital Television. At the meeting, the National Development and Reform Commission and the Ministry of Industry and Information Technology sent officials at the bureau level to participate in the meeting.
Too many broadcasting standards
Since the age of analog color TV, global TV has formed a variety of independently developed TV systems, which has affected the convenience and scale economic benefits of the broadcast and television industry through uniform standards. The global broadcasters participating in the conference agreed that cooperation will be the best way to promote the future development of terrestrial radio and television.
It is reported that, taking terrestrial digital TV broadcasting as an example, this was originally a public service, that is, it allows users in rural and suburban areas to watch many programs without cable TV, and therefore involves a wide range of public interests. Have a huge impact. Many countries in the world have already launched terrestrial digital television broadcasting, and the coverage of terrestrial digital television broadcasting in the United States has reached 99%.
But at present, four different terrestrial digital TV broadcast transmission standards have been formed internationally, namely the ATSC standard in the United States, the DVB-T standard in Europe, the ISDB-T standard in Japan and the standard in China.
China started the standard-setting process in 1995. The original National Science and Technology Commission established a digital high-definition television overall group (referred to as the overall group) to set up a ground standard with independent intellectual property rights for China. At first, the overall group relied on the Broadcasting Science Research Institute under the State Administration of Radio, Film and Television (which was appointed by the Academy as the first group leader. Later, Zhang Wenjun, vice president of Shanghai Jiaotong University, took over as the group leader, and Zhang led the organization of standard R & D work. Both the Science and Technology Commission and the original State Planning Commission have allocated considerable funds for project support. Finally, on August 18, 2006, China promulgated its own terrestrial digital TV transmission, which will be officially implemented from August 1, 2007. .
Due to the wide variety of standards, countries are also generally aware of this obstacle. On November 11th, the above-mentioned 13 international organizations jointly issued a Shanghai declaration entitled "Global Road to Future Terrestrial Radio and Television". Fang expressed the consensus on the development path of terrestrial radio and television, and also expressed the future. Willing to jointly explore a unified standard for global terrestrial radio and television.
Joint commitment to explore unified terrestrial broadcasting standards
It is reported that technical experts from various countries have put forward three proposals:
One is to discuss the needs of future terrestrial broadcasting systems. The "Declaration" states: "Portable and mobile applications, higher-resolution system applications, broadcast applications in emergencies, and applications that provide personalized services to people with special needs are the key requirements for future terrestrial digital TV broadcasting. In addition The cooperation between broadcasting and the Internet will provide more attractive services. The broadcasting industry should be committed to developing the necessary new technologies, constructing future broadcasting systems, and creating new services. "
2. Explore a unified terrestrial broadcasting standard. The "Declaration" states, "Our goal is to promote cooperation between broadcasters, communication companies, broadcast equipment and various receiving terminal equipment manufacturers. We will use frequency resources as appropriately and efficiently as possible Promote communication and cooperation between the communication system and broadcasting at the level. On the basis of giving full play to the advantages of the existing different technical systems, strive to explore unified international standards and promote industrial development through technological integration. "
The third is to promote global technology sharing. The Declaration stated that "The future broadcasting ecosystem will cooperate among different broadcasting organizations, scientific research institutes and enterprises to promote the development of new broadcasting technologies. We will work together to explore and eliminate gaps in broadcasting technology, which will make the world Developed and developing countries share the results of technological progress in the field of radio and television.
