Difference Between TV and HDTV

TV vs. HDTV

High Definition Television, or HDTV, is the current trend of all TV sets on the market today. An HDTV set simply means that it is able to display images that have a much higher resolution, when compared to standard TV. DTV stands for Digital Television, and though they often go together with HDTV, they are totally independent technologies, that can be used in tandem or independently. Digital Television covers the digital transmission of moving images and sound, and is the successor to the current analog TV, that is widely in use today.

The common misconception that people make with HDTV and DTV, is that you only need to buy an HDTV set to get high definition video. An HDTV set can process DTV signals, but to maintain backwards compatibility with older systems, it also accepts analog signals. Even if you have an HDTV, but you are still receiving analog TV signals, then you still have standard definition. Although HD is feasible on an analog transmission system, the huge bandwidth requirement spelled its early demise, and all HD videos nowadays are on DTV.
