| نماذج قطارات البتات الإدراكية الهجين من أجل القياسات الموضوعية لجودة الفيديو |
توصف التوصية ITU-T J.343 طرائق قياس جودة الفيديو الموضوعية التي تستعمل بيانات قطار البتات بالإضافة إلى تتابعات الفيديو المعالجة. ويمكن لهذه النماذج أن تحصل من بيانات قطار البتات على معلومات إضافية عن نوع الكوديك ومعدل البتات ومعدل الأرتال وبعض أخطاء الإرسال والإزاحات المكانية/الزمنية. وبالتالي، يمكن لهذه النماذج أن توفر أداءً أفضل مقارنةً بنماذج جودة الفيديو الموضوعية التي لا تستعمل إلا تتابعات الفيديو المعالجة. |
