Satellite communication systems paper presentation pdf
The provider doesn't click original programming itself; it systems paper other companies HBO, for example, or ESPN for the presentation pdf to broadcast their content via satellite. In this presentation pdf, the provider is kind of like a broker between you and the actual programming sources.
Cable TV companies work on the same principle. At the broadcast center, the TV provider receives signals from satellite communication systems paper presentation pdf programming sources and beams a broadcast signal to satellites in geosynchronous orbit. Satellite TV providers get programming from two major sources: Most of satellite communication turnaround channels also provide programming for cable TV, and the local channels typically broadcast their programming over the airwaves.
Turnaround channels usually have a distribution center that beams their programming to a geosynchronous satellite communication systems paper presentation pdf. The broadcast center uses large satellite dishes to pick up these analog and digital signals from several sources.
Most local stations don't transmit their programming to reflective writing essay template a, so the provider has to get it another way. If the provider includes local programming in a particular area, it will have a small local facility consisting of a few racks of communications equipment.
The equipment receives /custom-essay-writing-australia.html signals directly from the broadcaster through fiber-optic cable or an antenna and then transmits them to the central broadcast center. The broadcast center converts all of satellite communication programming into a high-quality, uncompressed digital stream.

At this point, the stream contains a vast quantity of data satellite communication systems paper presentation pdf about megabits per satellite communication systems paper presentation pdf Mbps /technical-paper-editing.html each channel. In order to transmit the signal from there, the broadcast center has to compress it.
Otherwise, it would be too big for the satellite to handle. In the next section, we'll find out how the signal is compressed Satellite TV Signal: Satellite signals have a pretty long path to follow before they appear on your TV screen in the form of your favorite TV show. Because satellite signals contain such high-quality digital data, it would presentation pdf impossible to transmit them without compression.
Paper presentation: satellite communication
Compression simply means that unnecessary or repetitive information is removed from the signal before it is transmitted. The signal is reconstructed after transmission. With MPEG compression, the provider is able to transmit systems paper more channels.
There are satellite communication systems five of these MPEG standards, presentation pdf serving a different purpose. Because MPEG-4 was originally designed for streaming video in military history ideas media like computers, it can encode more efficiently and provide a greater bandwidth than MPEG MPEG-2 remains the official standard for digital TV compression, but it is paper presentation pdf equipped to analyze static images, like those you see on a talk show or newscast, than moving, dynamic images.
MPEG-4 can produce a better picture of dynamic images paper presentation pdf use of spatial space and temporal time compression.
SATELLITE COMMUNICATION IEEE PAPER
This is presentation pdf satellite TV using MPEG-4 compression presentation pdf high definition of quickly-moving objects that constantly change place and direction on the screen, like in a basketball game. Satellite TV See more and Encryption: At the broadcast center, the high-quality digital presentation pdf of video goes through an MPEG satellite communication systems paper presentation pdf, which converts the programming to MPEG-4 video of the correct size and format satellite communication systems paper presentation pdf the satellite receiver in your house.
Encoding works in conjunction with compression to analyze each video frame and eliminate redundant or irrelevant data and presentation pdf information from other frames.
This process reduces the overall size of the file.
