Subjective quality evaluation is used to optimize the produced audiovisual quality from fundamental signal processing algorithms to consumer services. These studies typically follow the basic principles of controlled psychoperceptual experiments. However, when compromising compression and transmission parameters for consumer services, the ecological validity of conventional quality evaluation methods can be questioned. To tackle this, we firstly present a novel user-oriented quality evaluation method for mobile television in its usage contexts. Secondly, we present the results of an experiment conducted with 30 participants comparing acceptability and satisfaction of quality as well as goals of viewing in three mobile contexts and under four different residual transmission error rates, when the participants also performed simultaneous assessment tasks. Finally, we compare the results with a previous laboratory experiment. The studied error rates impacted negatively on all measured tasks with some contextual differences. Moreover, the evaluations were more favorable and less discriminate in the mobile contexts compared to the laboratory.
