Paper Abstract

Traditionally, subjective quality assessments are made in isolation of mediating factors (e.g. interest in content, price). This approach is useful for determining the pure perceptual quality of content. Recently, there has been a growing interest in understanding users' quality of experience. To move from perceptual quality assessment to quality of experience assessment, factors beyond reproduction quality must be considered. From a commercial perspective, content and price are key determinants of success. This paper investigates the relationship between price and quality. Subjects selected content that was of interest to them. Subjects were given a budget of ten pounds at the start of the test. When viewing content, subjects were free to select different levels of quality. The lowest quality was free (and subjects left the test with ten pounds). The highest quality used up the full budget (and subjects left the test with no money). A range of pricing tariffs was used in the test. During the test, subjects were allowed to prioritise quality or price. The results of the test found that subjects prioritised quality over price across all tariff levels. At the higher pricing tariffs, subjects became more price sensitive. Using data from a number of subjective tests, a utility function describing the relationship between price and quality was produced.
