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