Abstract

Bu buluş, bir yayın ve alıcı sistemi ve bunlara yönelik şartlı erişim sağlama sistemi ile ilgilidir . Bu buluş, bir sağlayıcı tarafından korunan bir içeriğin bir bilgisayar ağında yeniden gönderilmesini ve abone kontrolünün içerik sağlayıcı tarafından engellenmesini mümkün kılar . Bilgisayar ağındaki buluş konusu dijital ortam sistemi, sağlayıcı içeriğinin akışlarını uyarlamak ve bilgisayar sisteminin ip adresini buraya atamak üzere kullanılan ve kendilerine, bir ortam oynatıcısını (ses, görüntü, oyun), şifre çözücüyü (dekoder) ve sunuculara bağlı bir içerik istem modülünü içeren bir grup ağ terminalleri tarafından erişilebilen, bir abonenin bir lokal bilgisayar ağına ve içerik sağlayıcısına ait kontrol kelimelerinin korunması için gereken oturum anahtarlarını temin eden bir doğrulama sunucusuna erişmesini kontrol etmek üzere kullanılan bir grup sunucuyu içerir . Kontrol edilebilir bir sistemin oturum anahtarları ve akış uyarlama sunucuları, sağlayıcının içeriğini koruyan ve sonradan bir içeriğin denetim hakkı mesajlarına dahil edilen kontrol kelimelerinin şifresini çözmek için kullanılır .
