FIELD: information technologies.
SUBSTANCE: method is realised using the following facilities, where a DVB-T modulator comprises serially joined units, an interface, a randomiser, a Reed-Solomon encoder, a convolution interleaver, a convolution coder, a bit interleaver, a symbol interleaver, a QAM shaper, a calculator of reverse quick Fourier transform (RQFT calculator), a digital to analogue converter (DAC), a high-frequency unit (HF unit) and a shaper of pilot signals at the inlet of the QAM shaper, and also the following units are additionally introduced: a unit of packets breakdown, receiving information from the interface and sending it to the randomiser and a control unit, a register receiving signals from the randomiser and sending a signal to the Reed-Solomon coder and the convolution interleaver, the control unit receiving information from the unit of packets breakdown, and outlets are connected to all modulator units.
EFFECT: reduced requirements to a computing device due to optimisation of processes of synchronising operation of all units in whole, using less efficient computing devices.
