Digital over-the-air TV transmissions require a lot of broadcast spectrum - wide enough for each station to transmit four different TV signals at once. This wide broadcast spectrum can also make it easier for viewers to interact with their TV sets.More >>
If your local stations are transmitting digital signals and you're watching on cable - you aren't getting a digital picture. In order to receive digital TV pictures, you must have a digital TV set with a digital tuner.More >>
For digital television, the numbers sound impressive: two million TV sets sold in the last three years. However, most of those sets aren't being used to receive digital over-the-air broadcast signals.More >>
North Reading, Massachusetts-AP -- Anyone who's seen "Pearl Harbor" or "Saving Private Ryan" in a Dolby Digital-equipped theater knows what an intense sound track can do to bring realism to the movie experience.
A lot of the sound effects are loud, low-frequency types -- produced faithfully by the high-quality speakers in such a theater. But at home, much of that experience is lost -- unless you add a subwoofer to your home theater system. The subwoofer is designed to reproduce those low-end sounds with incredible similarity to the big theater. And subwoofers come in many sizes and shapes, and range in price from reasonable to outrageous. B-and-W Loudspeakers of America reminds customers that you get what you pay for, whether buying one of their subwoofers or another brand. B-and-W has subwoofers ranging from several-hundred dollars to as much as three thousand. It all depends on how much realism you want... and how much noise your neighbors will tolerate.
