Tuning in to Digital TV

摘要

Let's get one thing straight: Digital TV is not synonymous with high-definition digital TV (HDTV). It's much more than that. Digital TV encompasses not only HD, but satellite TV, cable TV, Internet Protocol TV (IPTV), and mobile TV as well. So, is it the next big thing? Believe it or not, you likely have digital TV already, possibly several of them. And you may not even realize it. In fact, the number of digital TV sources continues to climb, as does the number of products that display it. And expectations are that all of these products will find some kind of consumer success.
