Starting in the 1990s , modern television sets diverged into three different trends:
• standalone TV sets;
• integrated s ys tems with DVD players and/or VHS VCR capabilities built into the TV
s et its elf (mos tly for small s ize T Vs with up to 17" s creen, the main idea is to have a
complete portable system);
• component systems with separate big-screen video monitor, tuner, audio system
which the owner connects the pieces together as a high-end home theater system. This
approach appeals to videophiles who prefer components that can be upgraded separately.
There are many kinds of video monitors used in modern TV sets. The most common
are direct view CRTs for up to 40 inch or 100 c m (in 4:3) and 46 inch or 115 c m (in 16:9)
diagonally; mos t big s creen TVs (up to over 100 inch (254 c m)) use projection technology.
Three types of projection systems are used in projection TVs: CRT-based, LCD-based, and
DLP(reflective micromirror chip)-based.
Modern advances have brought flat screens to TV that use active matrix LCD or
plasma display technology (this last one more uncommon and more expensive). Flat panel
plasma and LCD displays are as little as 4 inch or 10 cm thick and can be hung on a wall
like a picture or put over a pedestal. They are multifunctional, because they are used like
computer monitors too (VGA).
Text 3. Home cinema
Home cine ma, also called Home theater, seeks to reproduce cinema quality video
and audio in the home.
The video aspect usually involves a large-screen and/or high definition television or a
projection system. Quality audio reproduction is usually achieved with a high fidelity
surround sound system.
"Home cinema" has become something of a buzzword. Technically, a home cinema
could be as basic as a simple arrangement of a Television, VCR, and a set of speakers. It is
therefore difficult to specify exactly what distinguishes a "home cinema" from a "television
and stereo".
However, "home cinema" implies a real "cinema experience" and therefore a higher
quality set of components. A typical home theater would include the following:
