    Default propagare sau?

    prin plimbarile mele prin tara ascult de obicei europa fm datorita acoperiri mari ce o au.insa am observat de multe ori ca radioul de masina atunci cand trece de pe un emitator pe altul apare o intarziere de cateva secunde.odata am numarat chiar 30 de secunde!cea mai mare veselie e atunci cand te afli in marginea de acoperire a 3 emitatoare si radioul sare de pe unul pe altu,ai impresia ca asculti la pickup si mai sare placa(cd romanesc)

    Fenomenul apare din retransmisie , eu nu am observat nicio data diferenta mai mare de 10 secunde .
    Fenomenul apare din tot lantul: studio-> codare A/D-> emisie catre satelit -> emisie satelit -> decodor satelit D/A -> filtre audio digitale -> emitator terestru.
    Eu am observat acelas lucru fiind pe acelasi post de televiziune cu receptorul de satelit si cu ss2 apare o intarziere foarte suparatoare de 3-4 secunde !

    europa fm emite nu prin satelit ci prin VPN prin vodafone ,intarzierea este citeodata si 20-30 secunde ,satelitul este back up
    asa ca de aici se trage toata povestea
