| Resumo: | This Technical Report introduces a set of parametric blocks composing an alternative model for quality assessment of videotelephony services to Recommendation ITU-T P.940. This model uses the same building block for audio quality assessing block and audiovisual quality assessing block as in clause 7 of Recommendation ITU-T P.940. Therefore, this Technical Report only describes other parts of the model: the video quality assessing block, audiovisual interaction delay assessing block, audiovisual media synchronization assessing block and videotelephony quality assessing block. Clauses of this report address the description of the various building blocks of the model and their formulae, as well as the performance of the model on the databases used for the validation of Recommendation ITU-T P.940. |
