Effects of IP packet loss and picture frame reduction on MPEG1 subjective quality

This paper evaluates the effects of IP packet loss and picture frame reduction on MPEG1 subjective quality in order to clarify how to apply quality-guaranteed techniques such as RSVP (resource reservation protocol) to the Internet. Subjective assessment tests showed that IP packet loss was the dominant factor in MPEG1 audio-visual quality degradation compared with picture frame reduction. Moreover, there was no difference between individual audio-visual quality contributions to the overall MPEG1 quality.
