Terms
4:3 and 16:9 Refer to the ratio between the width and height of the TV picture or screen. In a
conventional TV, the ratio is 4 to 3. Hence the term 4:3. Conventionally, most TVs
are built in this ratio. Therefore, broadcaster also broadcast picture in this mode.
However, there are also TVs which are built in a ratio of 16 by 9 (or widescreen)
which resembles a movie theatre because movie pictures are made in this mode.
New TV systems support both 4: 3 and 16:9 modes and can switch automatically
between them.
100 Hz A conventional TV shows a picture by scanning 50 times per second (50 Hz). This
Digital Scan frequency can be detected by the human eye in the form of a flickering picture.
100 hz sets show a picture by scanning 100 times per second eliminating the
field flickering. Philips' digital scan doubles the rate of line scanning, making it
undetectable. The result is a more stable picture that is relaxing for your eyes.
Audio Video A term often used when discussing a channel on a TV receiver or on a video
(AV) equipment, which has been designed to accept audio-video signals. This channel
automatically activates special circuitry within the TV to prevent picture distortion
or skewing. It is also used for audio-video processors, which handle both types of
signal.
CVBS Stands for Composite Video Baseband Signal. In broadcast television, this refers to
the video signal, including the colour information and syncs.
HDMI Stands for High-Definition Multimedia Interface. HDMI makes an uncompressed
digital RGB connection from the source to the screen. By eliminating conversion
to an analog signal, it delivers an unblemished image. The non-degraded signal
reduces flicker and leads to a clearer picture. HDMI intelligently communicates the
highest output resolution with the source device. The HDMI input is fully backward
compatible with DVI sources but includes digital audio. HDMI uses HDCP copy
protection.
HD Prepared Enjoy the exceptional picture quality of a true High Definition TV signal and be fully
prepared for HD sources like HDTV broadcast, Blue-ray DVD or HDVD. HD pre-
pared is a protected label that offers picture quality beyond that of progressive scan.
It conforms to strict standards laid out by EICTA to offer a HD screen that displays
the benefits of resolution and picture quality of a High Definition TV signal. It has a
universal connection for both analog YPbPr and uncompressed Digital connection
of DVI or HDMI, supporting HDCP. It can display 720p, and 1080i signals at 50 and
60Hz.
RGB signals These are 3 Red, Green and Blue video signals which directly drive the red, green
and blue emitters in the cathode ray tube. Using these signals provides better
picture quality.
System TV pictures are not broadcast in the same way in all contries. There are different
standards. This is not to be confused with PAL or SECAM colour coding. PAL
is used in most countries in Europe, SECAM in France, russia and most African
countries.
