MDSA Technology MPEG DVB2 TV

How It Works (at a glance)

The satellite, 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. A wide area of coverage can be achieved by using a cellular structure. The use of boosters can relay hundreds of analog or digital channels over many miles.

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

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