Television has revolutionised your entertainment life! Stay home and thrill to your very own experience with television. Watch your favorite sitcom images with your home TV setup. Turn that cricket game on your TV and bring those thrilling tackles up close and personal. Viewers can see dynamic, vivid colours on their television screen. The last few years have seen the emergence of a number of choices:
Digital Television
Digital sets are the closest step towards realizing high-definition TV, the format of the future. A high definition signal carries more than twice the resolution of current analog signals, and today's digital TVs are ready to receive those signals. Some have as many as 1,200 lines of resolution, delivering a picture without visible scan lines.
Direct-View TVs
The old tried-and-true standby is the direct-view TV. Direct-view TVs are identified by one common feature: the picture tube. Tube TVs don't get any larger than 40 inches (in diagonal measurement), but they integrate well into a living room home theater system.
Tube TVs are also best for gaming, since burn-in is less of a problem with a picture tube. Burn-in occurs when a stationary graphic is on the screen for a long period of time, causing a ghost-like after-image to permanently appear in the picture.
Home Theatre
Home Theater includes speakers that surround you to create an immersive experience. Home theater is all about coming as close as possible to the cinema experience without leaving the comfort of your couch.
Rear Projection TVs
Rear projection sets pick up at 40 inches and get larger from there
- quite a bit larger. These sets use a different kind of tube -
three of them, in fact - to produce the picture. These three tubes,
called cathode ray tubes (CRTs), project the picture in three colors
- red, green and blue - onto a large mirror that in turn projects
the images onto a screen. (The word "rear" in rear projection
denotes that the images that are projected onto the back or rear
of the screen. Conversely, traditional movie theaters use front
projectors, named so because images are projected onto the front
of the screen.
