vidtas
Vidtas is a theoretical unit used to quantify the perceptual value of audiovisual content in digital media. It is defined as the amount of perceptually relevant information conveyed per second of video, integrating spatial, temporal, color, and motion cues into a single scalar measure. The concept emerged in information science and cognitive perception discussions as a way to bridge objective bitrate metrics with human viewing experience.
Concept and measurement: A vidta can be computed by applying a perceptual model to a video sequence,
Applications and reception: In research and industry, vidtas have been proposed as a complementary metric to
Limitations: The measurement depends on models of human perception, display characteristics, and viewing tasks. As a
