Relatively speaking, the latter even more people concern, in accordance with the planning of the State administration of radio, in 2008 a comprehensive promotion of digital terrestrial transmission of high definition television, and in 2015 close an existing analog TV broadcasting. You can say, who mastered the HDTV standards will have digital TV in China's economic lifeblood. In recent days, the decision for CCTV adopt MPEG-2 as HDTV codec standard, was silent for a few days of domestic standard AVS working group finally sit still, says CCTV adopt MPEG-2 standard will step DVD footsteps, national year of at least 100 million additional patent fees. And MPEG-2 to each terminal 2.5 USD compared to domestic AVS standard only one Terminal 1 Yuan, just symbolic. And audio and video decoding technology is digital TV, DVD, CD, mobile video communication, video phone, key technologies, only enable standard of domestic AVS to promising emerging from our audio-visual area is relinquished. In addition, we also note that, in the homemade AVS101 HD decoding chip contains two Godson 1 IP soft core, on the Godson of IP-based CPU and industrialization promotion is of great practical significance.
Enable domestic standard AVS, a conducive to national consumption, contribute to the rise of domestic industry. In the "Super girls" value judgement on CCTV's different people can understand, in this type of relationship to the national development plan, CCTV also mixed up?
Why not give national opportunity?
Why not give domestic standard CCTV, the author considers the following three reasons:
AVS standard to be
The full name is Chinese AVS audio video coding standard working group, was established in June 2002, mainly China part of the research institutions and enterprises to develop color TV with independent intellectual property rights of audio and video decoding technology, which was established. Launch of the AVS standard is equipped with independent intellectual property rights of the second generation of source coding standard that addresses the key issues is a digital audio and video coding compression of massive data, also known as digital audio and video codec standard technology. It is a digital information transfer, storage, playback, and other links of the premise.
But unfortunately up to now this standard is not final official promulgation, stability based on demand, in order to ensure the fidelity of the signal transmission, CCTV employs the foreign MPEG-2 standard is logical. MPEG-2 is currently the most internationally accepted standards, the development of video and audio for a longer time, technology is more mature, there are many successful case for reference.
High definition film sources is a key
In fact, the broadcast of HD programming, Hangzhou was not the first. Early 1999 50th anniversary ceremony of CCTV is made of high-definition broadcast, but the ones least debated with broadcast are duplicate content, unable to attract more users. Not necessarily the size of the program groups, there will be no advertising revenue, television on HDTV's huge investment will not have any return. We can say that HD content has become the bottleneck of the entire industry.
Admittedly, AVS standard not only cheaper than MPEG-2, but the relevant terminal product AVS is not listed use, even for the CCTV use AVS standard digital TV signal through the AVS is sowing doesn't. And high-definition professional NLE machine prices in some way, the data throughput is too big, also lack the appropriate personnel to produce high-definition programming, high-definition on Ma is around the corner, you can only rely on foreign colleagues in content support. In addition, MPEG-2 not only ones, but also in terms of copyright protection, foreign peers generally more agreeable to MPEG-2 codec standards, it can better protect their copyright. Enabling MPEG-2 is not.
China high-definition need quick start
Development of high-definition programs ºcctv, a few years ago on the brewing of technology, for the sake of stability, first using this old technique MPEG-2 is very normal. And the foreign experience, launch high-definition TV channel you want to have a fairly long period of market launch, such as United States has spent almost 4 to 5 years. 2008 make more Chinese viewers to see HD programming for CCTV are a problem of their own development, but also a political task. CCTV not only to themselves well, also led other television stations followed by start. In a sense, CCTV HD must take the lead in creating a successful case.
Only the future appears more HD channels, China's high-definition market is likely to be genuine activation. But starting in 1999, Sony sold to China's first high-definition television ob van, HD equipment market has been dormant for six years. All the television watching is due mainly to the profit model now SD is selling advertising, if you play high-definition audience, new business models how to establish the cost of replacement equipment to recover? currently in China are not successful cases can draw on. So, CCTV HD must be shot in popularity. From standard definition to high definition is a revolution in radio and television industry, just like in color from black to, spent 18 years popular black and white TV, spent 12 years universal color TV, HDTV, how many years of universal need? CCTV HD must lead to an effective business model that drives the overall digital television, which can look forward to moving our HDTV undertakings obtain rapid development!
Day
Cargo sounds so good?In addition, let the Chinese consumers some sensitive issues include: manufacturers of CCTV why chose Japanese products, I believe that at least the following two reasons:
High definition digital rapid development in Japan and the United States of America
Currently, high definition digital TV in Europe and the United States, Japan and other developed countries are able to rapidly spread, digital high-definition programming source will explode. So said and Panasonic cooperation, at least in the operation mode and the ones of many worthwhile. But Panasonic very early on to become a strategic partner of the Olympic Games in China, this time joining together to create the "CCTV HD high-definition 2008" is also very natural.
Secondly, CCTV and Panasonic's current cooperation does not have exclusive, TCL, KONKA, etc. Skyworth and Chinese household electrical appliance enterprises still have a chance to cooperate with CCTV. But at present, China's 4 million TV user, only the 1 million user looking to cable television, other see the satellite or terrestrial transmission of television programmes, whether domestic standard AVS or domestic appliances are also has a wider area of cooperation.
Panasonic mature ones making equipment
At present, China's high-definition production equipment market is Sony, Panasonic and Thomson one third of the world. From product sales, Sony is doing in China's biggest, and probably accounts for more than half of the entire market; from the product categories, Thomson is the product line up, but this piece of ischemic recording equipment; and Panasonic is only one product line is the recording equipment, is Thomson's sales more than doubled. So China radio market with half the money is invested in the recording device, and this part is the highest value, also, Panasonic in pieces of original production areas have a lot of experience worthy of study.
Hua AO jingchuang is a protected by domestic and foreign parties strong support, with China's independent intellectual property rights of broadcasting and TV equipment manufacturing company. It is also wise to see pieces of original record device this largest market, the recent independent research and development of easy spare card DataCam DDE-380 data editing video recorder not only can you accept SONY Blue-disc system for MPEG-2 I-frame compression 50Mbps of MXF files, you can also accept the Panasonic DVCPRO P2 card, DVCPRO50 compression format of MXF files, and other non-linear editing format. We believe that through cooperation with Panasonic CCTV is bound to make homemade hi-def create more learning opportunities, and open up wider application market.
Not to the AVS! need to explain that not only is the CCTV, AVS itself
Safe to say that, from a global perspective, HDTV trends irreversible, China high-definition of the interests of all people in the world know, the standard also worry about people who stalk in the throat. But high definition digital channel is made up of producers, channel transfers, Internet access, terminal stations, operation and maintenance, and other aspects of a complete industrial chain. By AVS-advanced, lianjiaxing far, also must have the support of national policy and the industrialization of support!
So "not to chance, Chinese AVS standard in their own country does not have any real chance of running, how mature?!" this question behind the need for an explanation of optical is CCTV!
