Abstract

Bir dijital odyo/video bilgisi sinyali iletmek için OFDM bazlı yayın verici düzeneği olup, burada dijital odyo/video bilgisi sinyalinin kodlanmış bir versiyonu bir ağ tabakası bilgi sinyali elde etmek için DAB, DVB-T veya DVB-T2 tekniğine uygun olarak bir ağ tabakası kapsülleme aşamasında kapsüllenir. Ağ tabakası bilgi sinyali daha sonra bir Veri Hattı Tabakası bilgi sinyali elde etmek için bir Veri Hattı Tabakası dönüşüm aşamasında dönüştürülür, bu sinyal bir yayın bilgisi iletim sinyali elde etmek için bir Fiziki Tabaka dönüşüm aşamasına tabi tutulur.
