| تقنيات القياس الموضوعي للجودة الفيديوية الملموسة في تلفزيون كبل رقمي بوجود المرجع الكامل |
توفر التوصية ITU-T J.144 المبادئ التوجيهية بشأن اختيار معدات ملائمة لقياس الجودة الفيديوية المدركة موضوعياً لاستخدامها في تطبيقات التلفزيون الكبلي الرقمي عندما تتوفر الإشارة الفيديوية المرجعية الكاملة. ولم تتضمن مواد اختبار الصحة أي خطأ في القنوات. وتحدد هذه التوصية النماذج الحاسوبية الموضوعية التي تبين أنها تفوق ذروة معدل الإشارة إلى الضوضاء كأدوات قياس أوتوماتي لتقييم جودة الفيديو. وتشتمل هذه التوصية المراجعة على أربع طرائق موضوعية من أجل تقييم الجودة الفيديوية المدركة في القسم الناظم. |
