In this work, we present the results of a psycho-physical experiment in which a group of volunteers rated the quality of a set of audio-visual sequences. The sequences had up to three types of distortions: video coding, packet-loss, and frame freezing distortions. The original content used for the experiment consisted of a set of high definition audio-visual sequences. Impairments were only inserted into the video component of the sequences, while the audio component remained unimpaired. The objective of this particular experiment was to analyze different types of source degradations and compare the transmission scenarios where they occur. Given the nature of these degradations, the analysis is focused on the visual component of the sequence. The experiment was conducted using the basic directions of the immersive experimental methodology.
