| نظام نفاذ مشروط قابل للتنزيل للشبكات أحادية الاتجاه - معمارية النظام |
توصف التوصية ITU-T J.1027 نظام نفاذ مشروط قابل للتنزيل (DCAS) أحادي الاتجاه للشبكات أحادية الاتجاه. ويحمي النظام DCAS أحادي الاتجاه المحتوى الإذاعي أو الخدمات ويراقب استحقاقات المستهلكين مثل أنظمة النفاذ المشروط (CA) التقليدية، ويمكّن مطرافاً، مثل جهاز فك التشفير (STB)، من التكيف مع نظام النفاذ المشروط الجديد بتنزيل وتركيب عميل جديد لنظام النفاذ المشروط بدون تغيير العتاد. وعلى وجه الخصوص، يمكن لنظام DCAS أحادي الاتجاه أن يعمل بشكل كامل في شبكات التلفزيون الكبلي (TV) أحادية الاتجاه وغيرها من الشبكات أحادية الاتجاه مثل شبكات التلفزيون الساتلية. |
