◎At the same time many other countries are also included in the itinerary of this reform schedule, and as it a forcibly reform project.

　

The Advent Of The Era Of HDTVThe Advent Of The Era Of HDTVThe Advent Of The Era Of HDTVThe Advent Of The Era Of HDTV Since 2000, to improve the image quality of TV broadcasting, the broadcasting started to transform the signal from conventional analog signal into digital signal,. This reform of signal technology has been developed as a global-wide project today:

◎ In 2004 the United States has conducted such technological changing. In 2006 FCC has transformed the National television Broadcast signals into HDTV digital signal, and will fully stop to

broadcast the analog signals in 2009. ◎Taiwan will start to broadcast the digital HDTV in 2008.

◎China officially launched conversion project of digital television signal in 2006.In 2008 Beijing Olympic Games comprehensive TV will broadcast signals with high-definition digital.
