Abstract	Mobile TV services are available in an increasing number of countries. For cost reasons, most of these services offer material directly recoded for mobile consumption (i.e. without additional editing). This paper reports the findings of a study on the influence of text legibility and quality on the perceived video quality of mobile TV content. The study, with 64 participants, examined responses to news footage presented at four image resolutions and seven video encoding bitrates. The results showed that a simulated separate delivery of a news ticker and other textual information significantly increased the perceived video quality of the entire screen for native speakers. In addition, some automatable changes to the layout of news content resulted in substantial increases in perceived video quality. The results can be used to quantify the perceived quality gains when considering text delivery separately from the video stream and in the development of more accurate multimedia quality models.
