A system for transmitting content to transmitters of dvb-t synchronous network includes at transmitting site: a multiplexer of transport stream MPEG-2 having adapter SFN, to which sources of transport stream are connected, a receiver of signal of GPS system with antenna having outputs connected to a multiplexer. To multiplexer output, a modulator is connected. At receiving site, the system includes a receiver-decoder of corresponding standard connected at intermediate frequency, to output of which a transmitter of synchronous network DVB-T standard is connected, to corresponding port of which GPS receiver outputs are connected. Transmitter outputs are connected to transmitting antennas DVB-T. QPSK modulator output of the main station is connected to line channel input of a transmitter of a satellite transmitting station being composed of a particular converter, a power amplifier, transmitting antenna. At receiving part, an abonent station is installed. The station includes an antenna, a converter of particular range in intermediate frequency range with output connected input of the receiver-decoder. |
