Digital satellite broadcasting services start in December 2000. Digital satellite broadcasting enables broadcasters to provide high-definition television (HDTV) service with advanced audio coding (AAC) digital surround sound or multicasting of three standard-definition television (SDTV) programs.Digital satellite broadcasting services, there are a number of ways to implement the service. To start, consider that you will need satellite related equipment at both the source and destination ends of the broadcast. The primary use of satellite broadcasting is typically to transmit one party's message to many and therefore the "source-end" equipment is likely to be needed only for one location while the "destination" equipment may be needed at many locations.The digital terrestrial TV broadcasts have also the high picture and sound quality of digital high definition (Hi-Vision) and attractive interactive features. Data broadcasting in Japanese characters provides information tailored to each locality. The digital terrestrial broadcasts are received by UHF antenna.

Satellite broadcast to take place, the point of origin must transmit a signal to a satellite that it then relays back to Earth. One method to transmit the signal to a satellite is for an uplink truck equipped with audio and video control equipment, transmitters, and a satellite uplink dish, to transmit the source signal to a geo-synchronous orbiting satellite.Satellite broadcast is the distribution of video content over a satellite network.

The audio and video signals are acquired at the origination point and transmitted through an uplink truck to a geo-synchronous satellite.satellite broadcast include a production crew (line-producer, director, technical director, camera operators, audio, engineering, and uplink engineer); the production equipment (lights, switchers, cameras, microphones, uplink truck); a team of technicians at the source end and a downlink, tuner and television monitor at each destination location.Satellite broadcast to take place, the point of origin must transmit a signal to a satellite that it then relays back to Earth.

Digital data is different from analogue data, because there is usually very little data loss that occurs. Compare cassette tapes and audio CDs, the analogue tape has a series of frequency curves that tell the speakers what sounds to emit through an amplifier. CDs do much the same except data is contained in binary form (i.e. zeros and ones) the device or player recognises these zeros and ones and arranges them into a frequency pattern which is then transferred through to the speakers. Basically it is the same process as with a tape except with one extra step – converting from binary code into frequency curves. So while tapes get stretched and damaged, the frequency curves embedded on the film deteriorates. Whereas this hardly ever occurs with CDs because the data is stored behind Perspex and it’s hard to change a zero to a one (and vice-versa.)

But what is binary? As I said before, it is either a zero or a one – but how is this done I hear you ask. Well binary code is generated most commonly with lasers or magnets and is why we call media “digital.” Digital media encompasses all CDs, DVDs, Hard Disc Drives (computers), iPods etc. For CDs, a laser will burn a microscopic “dot” in the media which a device will identify as a “one.” All other sections that the laser does not burn are read as a “zero.” Hence binary code is made! Magnetic media works in a similar way except instead of burning dots, the drive will change the magnetic field at a particular segment to make a “one.” (more...)
