What do perceptual quality metrics (PQM) provide to cable operators?

Perceptual quality metrics (PQM) offer cable operators an objective measurement of human visual perception, which is crucial for assessing the quality of video transmissions. These metrics are designed to quantify the way viewers perceive visual quality, taking into account the complexities of human vision and the various factors that can affect it, such as compression artifacts, resolution, and frame rate.

By employing PQM, cable operators can ensure that the content delivered to viewers meets a certain standard of quality that is aligned with how humans actually perceive visual information. This scientific approach enables operators to make data-driven decisions about encoding, compression, and overall content delivery, ultimately enhancing viewer satisfaction and reducing the likelihood of poor reception impact.

In contrast, options reflecting subjective analysis, comparison of encoding techniques, or estimating customer satisfaction do not encapsulate the primary focus of PQM, which is firmly rooted in objective measurements rather than subjective experiences or indirect assessments.
