Recently, the introduction of HDTV standards, digital terrestrial television standard strong push, Wired Digital TV conversion, and so on, to give consumers the impression that the Chinese ushered in the "high definition digital TV age." While the CTV enterprises also hopes to be able to take the "high definition digital TV standard" train, homeopathy awareness of own high definition digital TV products.
The end color of the enterprise is just? end HDTV far away from us? this become distressed consumers two big questions. What is HDTV? many consumers may have to ask, high definition digital TV is not referring to enterprise promotion of digital TV?, in fact, such an interpretation is not correct, HDTV and digital TV are two different concepts, but high definition digital TV is not referring to a flat panel (LCD and plasma) TV. First, high-definition standards on TV. 1 January 2007 the formal implementation of the six digital television receiving devices — monitor standards, LCD, plasma HDTV if you want to known as the sharpness indicator must reach 720 lines. This standard means that the physical resolution usually need a 1366 × 768; in addition, the screen displays to the 16: 9 display standards. HD is a comprehensive concept, with the exception of the definition is an important indicator, circuit, brightness, contrast, etc. nearly 30 more indicators also check whether a TV is HD-TV. Although the LCD TV in high definition on an easy target, but its dynamic resolution but is it a big shortcoming, especially in more than 37-inch large-screen LCD TV. Due to the high definition standard is a recommended standard, many enterprises are stolen concept, call their LCD TV or plasma TV is HD-TV, 2005 "CCTV HD" is an example. New year begins, the requirements do not meet guojiaxinchanbu HD TV no longer play the "HD" flag. On the policy, there are solutions, while businesses have HDTV publicity cards decommissioning, POP, etc, but the sales staff or publicize their products as "national high-definition". In fact, a television with HDTV standards only through national certification can determine if consumers don't trust anyone, other institutions, profiled.
Then come to see what is a digital television. Digital television is not simply a TV, but digital content creation, content channel transport, Terminal receiving and displaying a system. Market common digital television, which is called by the TV company "digital TV", only in some internal TV has joined the digital signal processing technology, used to enhance and improve analog color television image and sound quality, but the antenna to receive signals for analog signal only, is not a real sense of digital TV. To watch digital TV, you can pass two methods, one is a digital cable TV, the other is a terrestrial digital TV. This need for radio and television operators send digital cable TV signal or wireless digital signal, plus cable TV set-top box or wireless digital TV set-top box to receive the signal. But there are many places also only analog signal transmission, so consumers are unable to watch digital TV. Finally to see high-definition digital TV. High definition digital television requires a high definition signal source, high-definition televisions, and digital television signals, digital TV receiver. While many TV companies are advertising themselves as high-definition digital TV, this is not correct. As HDTV is a huge system, not a simple TV will be able to achieve, this requires operators and TV companies together. High definition digital TV from us far from the above analysis, the majority of consumers buy TV won't be CTV enterprises publicity fooled. So, how high-definition digital television far away from us? from the point of view, HD TV high-definition LCD TV and at plasma TV prices still high as on million, in the short term and are still unable to effectively reduce the selling price, this impedes the popularity of high-definition digital TV; from a digital TV signal source, 2006 National complete digital TV conversion of user still only 1294.4 million, compared to the 2005 growth 275.2%, but not at the beginning of 30 million target and of 50%. While the national cable television subscribers up to 1.12 billion, complete digital TV conversion of user only for 1/10; at present, digital cable TV charges for $ 26, $ 22, $ 24, many users are digital cable TV charges higher and complain. China also has 3 million wireless subscribers, they are using the analog signal, State regulations 2007 and 1 August, all radio and television operators must be able to follow the digital signal ground standard publishing digital signals. These users are users in rural and suburban areas, income levels are low, a few hundred dollars for the start up fee and a $ 10 fee increases the difficulty of conversion. In addition, the digital television profit mode now is ambiguous, it also hinders the spread of digital television. Digital cable TV operators mainly by increasing month maintenance costs and increase profitability for sale set-top boxes, as Chinese consumers lower average income levels, so operators in custom programs on income less. Wireless digital TV is more difficult to find in addition to the advertisement a new profit-making mode, because users are generally low income rural users. Radio and television operators, TV companies, users, high definition digital industry chain of three key elements are not achieve high definition digital TV's conditions, short term HDTV for the majority of consumers still a dream.
The TV companies powerful concept of publicity, we are buying a TV?
The author gives consumers the following proposals: first, to see local operators publish signal. If it is a digital signal, you don't have to worry about, finance allows you to buy more than 37 inch LCD or plasma 50 inches above, funds were not allowed to buy short tube slim CRT or rear projection TV. Because the digital TV set-top box is free, so no need to spend more money to buy digital TV all-in-one.
Second, if this is the analog signal, what you buy, TV sharpness are quite Enterprise publicity of high definition digital TV without digital letter
Number of cases it is useless. And so there is a digital signal, the carrier will issue a set-top box, which requires a majority of consumers wait patiently. In the face of TV companies of high definition digital TV advertising, consumers should keep calm, do not be corporate false propaganda fooled. But recently, Beijing Gehua CATV recently to 10 partners announced digital HDTV in Beijing officially began marketing messages, and can only be seen as CTV enterprises and carriers combined show, due to the industry chain are not perfect and could not benefit consumers.
