FIELD: data processing.
SUBSTANCE: invention relates to the technology of broadcasting television programs, in particular to regional digital TV broadcasting of the second generation terrestrial (on-air) television and radio broadcasting standard (DVB-T2) using single-frequency networks (SFN). A device is proposed in which network tuning is performed by changing the parameters of the modified T2-MI stream generated in the replacer by replacing part of the T2-MI federal stream programs with regional T2-MI programs. Parameters management of the regional flow T2-MI of the SFN network is carried out simultaneously with the correction of the parameters of the federal T2-MI stream based on the results of estimating the data rate and bit error rates in the multi-channel receiver.
EFFECT: technical result is to ensure the operation of a modified regional SFN broadcasting network with a maximum or specified data rate and the required stability margin based on the bit error rate when it is deployed, as well as to monitor the performance quality during its operation.
