The inclusion of multimedia content in different web-based services has increased\r\nsignificantly. Through an extensive subjective testing campaign, we analyse the\r\nquality of experience concerning video transmissions associated to these types of\r\nservices when accessed from mobile devices and mobile Internet connections.\r\nContrary to traditional normalised quality assessment studies, we point out the\r\nservice context as a key aspect in quality assessments. Specifically, we analyse the\r\nimpact of the duration of the test material on quality assessments. We find out that\r\ntolerance to visual degradations is higher in the specific context of use compared to\r\nwhen using standardised methodologies for quality assessment, which has a\r\nsignificant impact in terms of commercial service acceptability.
