Innovative way to solve the problem of certification of DVB-T2 transmitters in Russia

Бесплатный доступ

The pending issue in digital TV and radio broadcasting technology is the certification of DVB-T2 standard transmitters, which are in operation in 85 regions of Russia. One of the main requirements to network transmitters, which is necessary for certification, is the requirement of time-calibrated information signal delay in modulators of network transmitters. The lack of time delay calibration of information signal processing is the main reason for technical defect in digital broadcasting, caused by the synchronization failure in the network transmitters. The results of the main stages of theoretical research and practical experiments carried out by the author earlier, which allow to take them into account in the development of the project «Rules of application of terrestrial television transmitters» at the level of the Ministry of Communications of Russia, are considered. The Ministry was renamed in its abbreviated name by Government Resolution No. 1389 dated September 9, 2020, into the Ministry of digits of Russia. The proposed algorithm of television transmitters settings, the innovative method and the calibration device, implemented on programmable logic integrated circuits, allow for synchronous operation of networks at the dispersal of information signal delays not only in the modulators of transmitters, as well as in data transmission channels. Upgrading of transmitters according to the recommendations of the article consists in additional equipment of modulators with one universal component of domestic production and adjustment of single-frequency network according to the algorithm considered. High manufacturability of the proposed solution allows to certify DVB-T2 standard transmitters in the shortest possible time and to provide reliable, uninterrupted TV and radio broadcasting by upgrading transmitters in operation in 85 regions of Russia.
