First, the concept of Internet TV. The emergence of the Internet and Internet access to television has triggered a revolution in the way of TV reception. Which directly led to the birth of “Internet TV”. The title “Web TV” was first proposed by the United States and also know as World Wide Web TV. As the name suggests, it is a form of media that uses the Internet as a transmission channel.
Here are the articles to explain, the concept of Internet TV
There are various theories about the concept of Internet TV. According to the analysis of the receiving terminal, there are two kinds of understanding. One is the Internet TV with the computer as the receiving terminal. And the other is the Internet TV with the TV as the receiving terminal.
The so-called Internet TV of TV terminals means that TV terminals can choose to watch and order digital TV programs through the set-top box, can browse information on the Internet, and provide TV program lists, information on TV, e-commerce, and other services. This is a cable television service that belongs to the category of digital television.
Digital TV (ITV or InterActive), also known as ” broadband interactive TV”, integrates network modules and application software with the TV core, and realizes online browsing through telephone lines or broadband. TV display and digital TV trinity of household high-brightness, high-definition display. Digital TV is the product of TV digitization and networking.
With the rapid development of network technology, digital technology, and multimedia technology, digital TV has achieved great development in many countries in the world. The related market value of digital TV content in the United States has exceeded 10 billion US dollars. The company predicts that the digital TV market in 2004 will reach 20 billion US dollars. China is the world’s largest TV consumer.
First concept
Experts estimate that if my country completes the transition from analog TV to digital TV within 10 years. There will be a market size of nearly one trillion yuan each year. Cities such as Beijing, Shanghai, Hangzhou, Shenzhen, Qingdao, and Foshan have carried out digital high-definition and standard-definition TV broadcast experiments. The CCTV Sports Information Channel, which has already been piloted, is a good example. This channel mainly provides sports information services.
When watching a sports game, viewers can use the remote control to call up a selection menu, and then choose to watch in segments. You can also choose to watch some relevant information about the game, such as the background of the game, player introduction, relevant comments, etc. So that the audience can fully understand all the information about the game. In addition, digital TV can also provide various information services. Such as stock information, weather forecasts, e-commerce, etc., and even realize the function of electronic banking under the condition of complete related technologies.
Second concept
This integration of the Internet and TV can separate from the Internet, but it can also combine with the Internet. Regardless of whether it is based on the Internet or not, the use of network technology to integrate the network and TV media enables TV media to have many network characteristics, making it no longer TV in the traditional sense, and overcoming many of the inherent deficiencies of TV media. theory and practice.
It has been proved that the integration of TV media and network media is not only a requirement of their development. But also the inevitable requirement of the development of digital technology in TV media. That is to say, digital TV has great market and development prospects. However, the development of the digital TV industry, like the development of the network broadcasting industry, still faces many bottlenecks that restrict its development.
Main concept;
These bottlenecks are mainly as follows:
First, the development of digital TV restricts by “infrastructure”. The “infrastructure” mentioned here includes two aspects: on the one hand, capital investment; on the other hand, the content of TV programs, which can provide a large number of service contents that can withstand the audience’s choice. Only when these two “infrastructures” are in place, digital TV can replace analog TV.
The second is high technical standards. To ensure that the content of digital TV programs can send and receive through different cable and satellite communication systems and set-top boxes of different brands, a unified standard specification must establish, which requires the industry to cooperate and cooperate.
The third is how to change the viewing concept of traditional TV users. Some people equate digital TV with video on demand. But the real value of digital TV is not limited to video content. Digital TV has many value-added service businesses that need to develop. People are still exploring digital TV resources and value-added services from different angles and the policies that should adopt. In addition, most viewers have a nostalgic feeling for traditional TV, which makes the growth of digital TV viewers slow. As a result, TV program producers are not very motivated to invest, and the digital TV industry has formed a slow cycle.
The so-called Internet TV of computer terminals refers to the way that users can order or watch film and television programs in real-time in the form of downloading and online broadcasting through the Internet. The “TV” in this “Internet TV” concept refers more to video content than to “TV”.
