Satellite television is a wireless
television system that can be accessed directly with a wider area. Satellitetelevision can provide distance and interference
solutions by transmitting signals through satellites.
Satellite Television Components
Satellite television has 5 main
components consisting of direct to home (DTH) or direct broadcasting (DBS)
satellite systems, namely:
1. Which broadcast source is the
channel that gives your television pictures to watch.
2. Transmitter center that can
become the main system center as a television service provider that can receive
signals from various broadcast sources.
3. Satellites which function to
receive signals from the transmitting station then the satellites can
re-transmit to earth.
4. Satellite dish that functions to
capture signals from satellites so you can watch television.
5. Receiver or receiver that
functions to process the signal.
Satellite TV broadcasts
Satellite television service providers get their channels through two main sources namely
through international channels and various local channels. Most international
channels that are used as satellites can provide broadcasts that are used for
cable television needs. The resulting transmitter center can transform all
existing broadcasts into digital streams for high-quality television.
Satellite Television Signals
Satellite television signals are rated
better than cable television. This is because satellite television signals
contain a lot of very high-quality and high-quality digital data. High signal
makes satellite television more preferred.
Compression Standards
Satellite television has and uses a
special type called the Moving Picture Experts Group MPEG-1: you can choose the
standard compress used in MPEG-1 to be used as encoding and also decoding on
your satellite television.
MPEG-2: When you choose MPEG-2, then you
can use it as a tool to compress your high quality files for your satellite
television.
MPEG-4: You can choose MPEG-4 when you
want to minimize the size of your video.
MPEG-21: While you can choose MPE6-21
related to multimedia.
As a frame, satellitetelevision has and contains better complete image
data. As a predicted frame that can provide enough information to satellite
television receivers, it can display frames based on frames. Meanwhile, as a
bidirectional frame, satellite television can display good information for your
television.
When the signal of satellite television obtained can reach the user's
home or user, the signal will be captured by the satellite dish through an
antenna designed to obtain a particular broadcast source. When a beam has made
it to the satellite dish, the radio signal can be transmitted to a certain
point. Then the LNB will filter the radio signals around the dish so that it
can then channel it to the satellite receiver in the user's home.
