Pwoteksyon siyal la nan yon zòn sèten ka bay pa yon kantite transmeteur, transmèt multiplex a nan televizyon dijital oswa siyal radyo nan kanal la frekans ki idantik. Kontribisyon pasyèl siyal yo nan pwen resepsyon an pa sèlman pa entèfere, nan sèten sikonstans lè sa a menm amelyore resepsyon an. Se konsa evidan ke rezo frekans sèl nan transmeteur dijital ka konsiderableman amelyore itilizasyon Gwoup Mizik frekans ak chanèl kòm byen ke balans enèji nan transmeteur dijital. Transmètè dijital nan SFN ka konsiderableman pi piti pouvwa pou kouvèti siyal la nan zòn yo bay la ase pou resepsyon bon jan kalite. Metòd nan SFN pa kapab itilize ak televizyon analogique terrestres difize a, kote an reyalite tout estanda televizyon mond lan prezan-jou sèvi ak anplitid vaksiman zepòl bandaj ak opere nan ...

The signal coverage of a certain area can be provided by a number of transmitters, transmitting the multiplex of digital television or radio signals in the identical frequency channel. Their partial signal contributions in the reception point not only do not interfere, under certain circumstances then even improve the reception. It is thus obvious that single frequency networks of digital transmitters may considerably improve the utilization of frequency bands and channels as well as energy balance of digital transmitters. Digital transmitters in SFN might be considerably lesser power for the signal coverage of the given area sufficient for quality reception. Methods of SFN cannot be used with the terrestrial analogue\ television broadcasting, where in fact all the present-day world’s television standards use amplitude vestigial sideband modulation and operate in
