MDSA Technology MPEG DVB-2 TV Broadcasting

How It Works (at a glance)

Received satellite programs, or terrestrial television programs, and local video productions, are fed directly into specially designed encoders that compress both video and audio source signals into a continuous output bit stream with a constant data rate. If necessary, the video and audio is encoded into a MPEG-2 DVB transport stream. The stream is then modulated QPSK and transmitted from the unidirectional or directional antenna to the consumer's home. A wide area of coverage can be achieved by using a cellular structure. The use of repeaters can relay hundreds of analog or digital channels over many miles. MDSA has built the largest system of this type in the world.

An MDSA MVDDS system can completely replicate a DBS satellite system like DirecTV or Dish Network.

At the consumer or subscriber end, reception of the transmission is quite simple. The subscriber receives the encoded television signal with an approximately 20 inch (53 cm) tall flat panel antenna or a small dish. The information is then decoded by a receiver and displayed on the subscribers' television.

MDSA MVDDS wireless terrestrial transmission system is a versatile and powerful broadcasting solution.
