Abstract

Bir uydu dogrudan yayin sistemi, yayin programlarinin bitlerini, bir çati içine toplanan, asil deger fazlaliklari içine toplamaktadir. Çatilar, asil oran kanallarinin bir çoklugu içine birden fazla mesajin gönderilmesini önleyen sembollere bölünmektedir. Asil oran kanallari, bir uyduya iletim için, tekabül eden, yayin frekanslarina birden fazla mesajin gönderilmesini önlemektedir. Bir gövde-üzeri (birden fazla mesajin gönderilmesini önleyen cihaz, yukari-link sinyallerini sembollerin zaman bölümlü birden fazla mesaj göndermis akimlari içine ayirmaktadir. Bir faz farki manüple demodülatörü, sembollerin, dijital temel bant bilgileri içinde ayarini bozmaktadir. Uydu yükü, sembolleri, iki ping-pong tampon ve bir yöneltme dügmesi kullanarak, zaman bölümlü birden fazla mesaj göndermis bilgi akimlari içine çevirmektedir. Alicilar, TDM akimlarini, uydu tarafindan saglanan çati baslangiçlari kontrol kanallari ve yayin istasyonlari tarafindan saglanan kontrol basliklari DEVAMI VAR
