The television broadcasting industry in the USA is ahead of schedule in deploying digital television (DTV), but its application to Intelligent Transport System (ITS) systems has been much slower. This article discusses DTV in some detail, and considers some of the problems of preparing for its use in ITS. The US Congress has supported the USA's rapid transition to the new Advanced Television Standards Committee (ATSC) DTV standard. Since then, many other countries have adopted this standard. By incorporating features that will be useful to TV equipment in ITS, the home entertainment market for DTV, supported by broadcast and cable TV, will be the driving force for ITS video technology. By 2003, DTV will have become very affordable, and the USA will phase out analog TV by 2006. There is already capability to deploy DTV in ITS. However, there are several reasons why ITS jurisdictions continue to use analog TV. Most CCTV cameras currently available are still mainly analog, though this situation will soon change. Another reason is a mistaken belief that DTV will not happen because of controversy over standards; the article discusses various relevant standards in some detail. Other reasons include perceived high DTV cost, and continuing sales campaigns by analog video technology companies.
