Recommendation ITU-T P.910 describes non-interactive subjective assessment methods for evaluating the one-way overall video quality for multimedia applications, such as videoconferencing, storage and retrieval applications, as well as telemedical applications. These methods can be used for several different purposes including, but not limited to, selection of algorithms, ranking of audiovisual system performance and evaluation of the quality level during an audiovisual connection. Recommendation ITU-T P.910 also outlines the characteristics, like duration, kind of content and number of sequences, of the source sequences to be used.
