Terrestrial digital TV transmission standard at the end of the mortgage "veil"

Digital TV standards at the end of the mortgage "veil"

By Tsinghua University, Shanghai Jiaotong University and the Academy of broadcasting science, the fusion of three programmes, the suspense is named CDMB-T.

The reporter was informed that the digital terrestrial television transmission standard used DMB-T, Shanghai Jiaotong University, Tsinghua University, the Academy of broadcasting science, ADTB-T TiMi three technical standards for integration into a unified new standards, provisional named CDMB-T, also known as DMB-TII, expected in late August.

Industry experts, the fusion programme will lead to the device provider to postpone the establishment of the industrial chain, and at the end of the power of IPTV front collision.

One-year transition period after the enforcement of

In mid-July, reports the "digital terrestrial television transmission standard finally results, Tsinghua University DMB-T standard was identified as the only standard", and that the message source is marking the digital new media Committee-sponsored digital new media Web site. Subsequently, the website in a prominent position on a declaration: "the digital new media Committee on digital terrestrial television transmission standard problems accepting any media access".

Press confirm all, finally, the Ministry of information industry digital TV standardization coordination group, the Tsinghua University Digital TV standards project director Yang knowing that the final adoption of the standard, the fusion named CDMB-T, also known as the ultimate title DMB-TII, is uncertain. In the introduction of process, this standard is still in the hands of the Chinese Academy of engineering, has not escalated to eventually have the right to the national standards Committee of the publication. But he said that the standard is most likely in late August.

In other words, the new standard will both Tsinghua multi-carrier and National Chiao Tung University single carrier two scenarios. It is learnt that the standard release also established a one-year transition period after the national compulsory, currently used in various parts of the European DVB-t terrestrial digital TV system in the standard release after will gradually withdraw from the market.

Profit model is the greatest challenge

As a result of the Academy of broadcasting science, of TiMi and Tsinghua University DMB-T programme belong to multiple carrier programme, Shanghai Jiaotong University programme is a single-carrier, different paths to integration solution. The State Deputy Chief Engineer du baichuan told reporters that although now that you have a very clear integration programmes, but the fusion of different evolutionary path will inevitably increase the cost programme. It is estimated that the integration of single carrier and multi-carrier techniques, not only greatly increases the complexity and cost of at least 30 per cent increase.

But the real challenge is the profit model. Digital TV maximum profit to be urban, urban families generally has a perfect cable TV network, the digital reconstruction after the General will be able to watch the SDTV programs, therefore, terrestrial digital TV on the digital cable TV has little effect on the market.

The industry believes that currently terrestrial digital TV only on certain market segments. Not long ago, the industry held a profit model of digital television, but the main topic of the seminar is triple background, based on the terrestrial digital TV integration programmes for the construction of the industrial chain, as well as various value-added business model of development. "At present, the third basic take is selling a set-top box and are receiving fee of profitability, while real earnings of pay-TV and value-added business but not sure. "Information technology Research Institute of Tsinghua University Digital TV Technology Research Center Director, China digital TV standard critical section-Ke, army told reporters," this development, not to mention the money, not lose money as well. ”

Digital TV, IPTV PK upgrade

Terrestrial digital TV in the family is the natural enemy of IPTV. In the outgoing transmission standard for digital terrestrial television soon to good news, IPTV also ushered in the exciting news. July 28th, Mii in their published information industry legal work situation "was revealed, the Telecommunications Act will bring to the attention of the national people's Congress considered, may be launched during the year.

Previously, Deputy Director, Office of the State had to Zhang Qiong, the Telecommunications Act will change the telecommunications services and radio and television services are not allowed to enter the status of each other.

Compare with digital TV, IPTV and user interactivity enables IPTV more market potential. On the other hand, IPTV content is not limited to television, interactive games, home information services, and other content can also show in this platform. The most important is it to fixed-line operators have a great temptation to not only serve to enhance the user's "stickiness" and reduce churn rate, you can also bring about the sustainable growth of broadband services. In other words, break after three networks, radio and TV sector cuts likely to compete with telecom sector IPTV market and accelerate the development of IPTV business.

In good conditions of urban household broadband, program resources and value-added business development will be launched IPTV platforms quickly, while the terrestrial digital TV must pass on set-top box technology continues to improve and upgrade to implement these features, this is not only the broadcasting and telecommunications at the technical strength, but also broadcasting and telecommunications systems business model.

Even if terrestrial digital TV transmission standard immediately introduced, but solve integration challenges need time, and IPTV are everything, but only until the resulting policy. In terms of timing, just prepare the power of digital television is difficult to avoid a collision with the front of IPTV.
