This paper deals with MMT (MPEG Media Transport), which is an application-level protocol for video transmission. We assess subjective QoE (Quality of Experience) and objective application-level QoS of video IP transmission with error concealment mechanisms of H.264/AVC and application-level forward error correction (AL-FEC) of MMT. In the experiment, we employ two contents, two types of the number of slices per picture frame, and two types of the total bitrate of video and its FEC code. We experiment with several load conditions. We then compare FEC schemes with three code rate values and no FEC scheme. From the assessment results, we show that the appropriate code rate for QoE enhancement depends on not only network conditions but also contents.
