   Remote destination quality monitoring when a copy of the source is available at the point of measurement. Quality measurement for monitoring of a storage or transmission system that utilizes Video compression and decompression techniques, either a single pass or a concatenation of such techniques. Lab testing of video systems. VQuad-HD flowchart

3. Video quality - Wikipedia

   en.wikipedia.org/wiki/Video_quality

   The main goal of many-objective video quality metrics is to automatically estimate the average user's (viewer's) opinion on the quality of a video processed by a system. Procedures for subjective video quality measurements are described in ITU-R recommendation BT.500 and ITU-T recommendation P.910. In such tests, video sequences are shown to a ...

4. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.

5. Subjective video quality - Wikipedia

   en.wikipedia.org/wiki/Subjective_video_quality

   The main idea of measuring subjective video quality is similar to the mean opinion score (MOS) evaluation for audio. To evaluate the subjective video quality of a video processing system, the following steps are typically taken: Choose original, unimpaired video sequences for testing; Choose settings of the system that should be evaluated

7. Mean opinion score - Wikipedia

   en.wikipedia.org/wiki/Mean_opinion_score

   Mean opinion score (MOS) is a measure used in the domain of Quality of Experience and telecommunications engineering, representing overall quality of a stimulus or system. It is the arithmetic mean over all individual "values on a predefined scale that a subject assigns to his opinion of the performance of a system quality". [ 1 ]

8. Perceptual Evaluation of Video Quality - Wikipedia

   en.wikipedia.org/wiki/Perceptual_Evaluation_of...

   Perceptual Evaluation of Video Quality (PEVQ) is an end-to-end (E2E) measurement algorithm to score the picture quality of a video presentation by means of a 5-point mean opinion score (MOS). It is, therefore, a video quality model. PEVQ was benchmarked by the Video Quality Experts Group (VQEG

9. Measurement system analysis - Wikipedia

   en.wikipedia.org/wiki/Measurement_system_analysis

   A measurement system analysis (MSA) is a thorough assessment of a measurement process, and typically includes a specially designed experiment that seeks to identify the components of variation in that measurement process. Just as processes that produce a product may vary, the process of obtaining measurements and data may also have variation ...
