Digital television national standard dashes on the ground General Bureau of Radio, Film and Television refuels after braking
August 1 this year, the digital television transmission national standard of ground (call " national standard " in the following text )Will implement in an all-round way. At the moment of only having the key for half a year left, State Bureau of Radio,Film and Television releases the notice and claims before this Spring Festival, move the digital television and delay examining and approving the new pilot project before planning to finish in technology. It is called this measure of General Bureau of Radio, Film and Television as that in the industry " Emergency brake " ,The relevant enterprises of industry chain have produced the attitude looked around too.
However, " the first finance and economics daily report " learns, last Thursday (March 15) ,Zhang Haitao, Deputy Bureau Director of State Bureau of Radio,Film and Television, has held the ground digital television and boosted work and led the group session, continuation is " The national standard " Implementation " Come on " .
Zhang Haitao emphasizes, accelerate technology's testing and the frequency is planned, guarantee CCTV broadcasts the ground high definition TV in Beijing in October of this year, guarantee to start broadcasting the ground digital television in Beijing, Shanghai, Qingdao, Tianjin, Qinhuangdao, 6 Olympic cities of Shenyang.
Step up making the related standard
Zhang Haitao spends at last week's meeting " Time is tight, the task is heavy " To describe the pressure that the national standard implement. He demands to do every preparation well. Confirm that develops digital video basic principle and great technical policy of ground as soon as possible, step up making the related standard, establish the system of fundamental technical standard.
Zhang Haitao points out, the popularization and application of the national standard are a technological change and a great system engineering at the same time, concern country's scientific and technical innovation and a major issue of national industrial development.
It is said frankly when being interviewed by " the first finance and economics daily report " that the scientific and technological committee's senior consultant's chapter of State Bureau of Radio,Film and Television one is frugal: "There is much preparation to be done before August 1, including related standard formulation, channel are planned etc.. "
It is said for example that the the chapter one is frugal, the necessary replanning of television channel of China. The cable television will not interfere with each other, but the radiovision, if the city is the same as channel between the cities or close, will interfere. Moreover, the digital television channel can't conflict with the present simulation channel yet, because a lot of ordinary people's television is still analog now. While keeping simulation channel, increase the digital channel, must plan.
As for the related standard, the cover network correlated to national standard plans standard, standard of network connection, signal transmission and distributing interface standard, transmitting set and receiver standard,etc., still in stepping up making.
It is reported, General Bureau of Radio, Film and Television still carries on the pilot project of technical application in Beijing, Jiangsu and other places, in 330 kinds of work patterns, 33 kinds of transmission code rates that the national standard support, confirm several kinds of work patterns and technical parameters suitable to popularize.
Anxious " it is messy to put "
"Not long ago, that notice under General Bureau of Radio, Film and Television, these projects of just letting all parts not start hastily. " It is spoken that the the chapter one is frugal. This notice issued before the Spring Festival, the full name is that " General Bureau of Radio, Film and Television is about further standardizing the notice that the digital television system technology of ground tested " (call " notice " in the following texted) .
" notice " reveals, specific unit popularizes the digital television system of ground not totally according with the national standard in some areas by oneself. So, " notice " emphasizes, without the permission of General Bureau of Radio, Film and Television, any unit can't carry on testing and unauthorized manipulation television channel of digital television technique of ground without authorization.
Insider think in implement, leave critical moment for half a year only still by force from national standard, one comes hastily to General Bureau of Radio, Film and Television " The brake " ,It is anxious " It is messy to put " ,It would be better first to unlock normally and again.
" plan, develop in harmony in unison " Become the key. " notice " points out, consider Chinese TV frequency resources have been already very in short up till now, in order to plan the frequency of digital television of ground, first set, the seventh set and province and the here first set of telecasts in the middle of construction of rural public service system except including in in the future, stop utilizing the wireless analog mode to be newly-set-up or relaying the examination and approval work of the television channel in principle, all frequency resources are used for carrying on the planning of the frequency of digital television of ground.
Meanwhile, it is not the conversion work with systematic national standard that the focal point of moving the pilot project of the digital television is existing, delay examining and approving the new pilot project before planning to finish in technology.
But Zhang Haitao emphasizes again at last week's meeting, strengthened the control over pilot project, carry out regulation and requirement that the general bureau has already send been strictly, further strengthen the cleaning work, it is not that the standardized system must be paid and changed to be clear, accomplish the strict enforcement of orders and prohibitions, guarantee the implementation of the national standard.
It is reported, more than 40 cities pilot the ground digital television in China at present. That is to say, the implementation of the national standard should finish " rotates and marks " in these cities first at least Work, and then the other cities and rural areas of China start broadcasting the ground digital television according to the national standard.
All parts wait " Open a sluice gate and draw out some water "
In fact, even " rotate and mark " ,It is being the final that all parts are waiting for the general bureau too " Issue an order " . An insider of system of some place broadcasting and TV say with feeling: "Change and mark the work and has not fixed up yet now, wait for the notice of the general bureau. The broadcasting and TV at present, it is nothing OK. The broadcasting and TV are a trade of unified planning, will switch off above now, just there is water as follows. "
However, a lot of operators have not felt pessimistic because of this. The figure of broadcasting and TV of Changsha moves the media Co., Ltd. Chairman, general manager to congratulate and is recognized as big, the norm at the beginning of this year of the digital television, are fermenting the next great development.
But archduke He says frankly it has difficulty in to all convert to the national standard before August 1. "First of all, it does not mean industrialization that the standard comes out, for example the related interface standard did not come out either; Whether the products could come out, whether there are chips, could be commercial, all these have a long times. " In addition, it is a question too that investment subjects are different. The investment subject of the system of broadcasting and TV is the departments of broadcasting and TV of all provinces and cities, because the regional financial resources are different, it can be unified that resources are planned, but investment is not unified, development will inevitablely be out-of-step.
Shenzhen moves Vice President of Co., Ltd. Hou Yao of telecom and says to reporters, they are doing the preliminary preparation that the national standard is being changed, including the adjustment of apparatus, network. "Rotate, be will inevitablely rotated, to start, change August 1 probably, at least several can finish changing month, install the terminal station and must take several months too after all. "
It is reported, probably there are 3000~4000 Shenzhen moves digital video terminal stations now, are mainly distributed in the bus, taxi, building and outdoor business street.
