Problems of DVB-2 standard telecasting with regional content insertion

This work is concerned with methods for the organizing of the First DVB-T2 multiplex with regional content telecasting insertion over various designs of SFN terrestrial broadcasting digital single-frequency network. We found problem on import substitution of technology for distribution program modification by using replacer because Enensys Technologies is owner of Russian patent of method and device for DVB-T2 broadcasting with regional content telecasting insertion. Disadvantage of used in Russian Federation technical solutions for problem of the First multiplex regional version telecasting is concerned with necessity of coincident T2-MI flow broadcasting in various regions with unified parameters stated by Federal Multiplexing Center. Because it is impossible to set optimal parameters for each region, there is a number of problems of SFN network stability providing, which are defined by bit error ratio. This factor can lead to technical drawbacks and under-utilization of designed network potentialities over bit rate.
