This study aims to understand the influence of the environment over the perception of Audiovisual quality on IPTV services. Thus, the test participants were distributed between 2 groups. One group performed the test in a living room lab. This laboratory has the typical characteristics
of a regular living room. The second group performed the test in a room which characteristics were based on the ITU Recommendation ITU-R Rec. BT. 500. To ensure the reciprocity of the conditions between both rooms, extreme care of environmental conditions were taken. Hence, factors such as
ambient light, ambient noise, temperature, and relation between TV size and viewing distance were replicated in both rooms. Preliminary results reveals discrepancies between subjective quality evaluations performed in both rooms.
