Quality Assessment for Mobile Media-Enriched Services: Impact of Video Lengths
The inclusion of multimedia content in different web-based services has increased significantly. Through an extensive subjective testing campaign, the authors analyze the quality of experience concerning video transmissions associated to these types of services when accessed from mobile devices and mobile Internet connections. Contrary to traditional normalized quality assessment studies, they point out the service context as a key aspect in quality assessments. Specifically, they analyze the impact of the duration of the test material on quality assessments. They find out that tolerance to visual degradations is higher in the specific context of use compared to when using standardized methodologies for quality assessment, which has a significant impact in terms of commercial service acceptability.
