The present invention relates to methods and systems for transmitting information over different information networks and in particular to a method for transmitting information in an integrated telecommunications and broadcast system. The method for transmitting information across the integrated telecommunications and broadcast system incorporating a cellular network and a broadcast network with a plurality of broadcast content providers connectable to transmitter/receiver equipment installed at least one base station of the cellular network, consists of broadcast content generation by broadcast content providers, connecting the broadcast content providers to an internal IP network for broadcast program distribution, transfer of the broadcast content from the broadcast content providers by means of the internal IP network via communication links and line transmission equipment of the cellular network, transmission of cellular network information over the communication links and line transmission equipment of the cellular network, generation of a combined information stream of the broadcast content information and information of the cellular network for its transmission to at least one base station of the cellular network, separation of independent streams—the cellular network information stream and the broadcast network information stream from said combined stream, and transmission of the separated independent information streams to the above-mentioned transmitter/receiver equipment for their further transmission over appropriate independent channels to subscribers of the integrated telecommunications and broadcast system, located within the coverage area of the integrated system.
