The more the economy develops, the higher the living standard of people becomes. As a result, their needs for information and culture are also higher, especially in television - a key public media. The television viewer’s requirements for content and image quality are becoming higher and higher.
In order to satisfy those requirements, BTV has selected the earth-link digital television format as the best solution to solve the conflict between the need for information and entertainment and the limitations of present technology. In comparison with other broadcast forms around the world like broadcast television, cable network television or satellite television, this form of earth-link digital television has advantages in content and image quality. This technology is satisfying the needs of users in the 21st century. After 3 years of deploying the service, it has become an essential service for Binh Duong audiences. Instead of viewing foreign channels directly, almost every audience in Binh Duong enjoys the selection of BTV programmes.
In fact, in this renewal period, the need for digital television is higher and higher, with more channels clogging the airwaves, having an adverse impact on image quality. Choosing digital television, BTV has basically solved the conflict between the requirement for television development and the circumstances of frequency exhaustion. Digital television helps improve of transmission quality as well as save the national frequency spectrum. In a normal 8MHz frequency channel, only one analog technology program can be broadcast. But via a digital television channel, eight programs can be broadcasted in the same bandwidth. This means the previous limitations in the development of television broadcasting have been removed.

Moreover, digital television has also solved the conflict between the requirement for “Modernisation†and “Short Cut Advancing†even with financial limitations to investing in new technology. For the television industry, “Modernizationâ€, and “Short Cut Advancing†in technology investment has always been a headache for industry management. As the more modern and high quality the technology is, the higher the cost will usually be. Higher cost means a limited investment. With an expected low return for low investment, this would normally be considered a wasted investment. The digital television format that BTV has deployed in three years has now proved that digital television is an exception to the rule. Many people believe that moving to a new technology requires expensive investment.
BTV have in fact taken full advantage of much existing equipment like antenna, feeders, television towers, similar image recorders or even analogue image broadcasting equipment. Furthermore, digital television has helped saved investment capital when only one new broadcasting machine can replace eight old ones with complex antennas attached. Every TV, including black and white ones, can be used to receive digital television programs, with an additional receiving terminal. And computer can also be upgraded to receive digital television programs too.
It can be seen that deploying a digital television broadcasting system doesn’t cost much but to take full advantage of existing equipment like cameras, videocassette readers, VCD, DVD players, is hard work, which requires effort and creativity. The biggest benefit is that we can advance far with less expenditure and with the ability to take full advantage of currenet technology. Digital television has the advantage of a broader frequency spectrum in comparison with analogue television while its high quality is guaranteed. Many areas that are hundreds of km from Binh Duong town centre can also easily receive its transmitted programs. This kind of success cannot be achieved with the old analogue technology. Therefore, the number of audiences has increased tremendously already.
