Question
What’s the difference between high definition and standard definition TV?
Answer
Both standard and high definition television are digital formats. Standard definition (SD) television provides digital images and sound that is considerably better than analog. High definition (HD) television is an enhancement that provides higher resolution images and Dolby Digital surround sound. If you connect a set top box to an analog television, or have a television with a standard definition digital tuner, you will receive all the standard definition free-to-air digital channels. To see all the benefits of high definition television, including the free-to-air HD channels, you need a television capable of displaying high definition images that either has a built-in HD tuner or is connected to a high definition set top box.
