R&S®AVBrun - Video analysis and speech quality test solution with the R&S®CMWrun sequencer software tool

With the introduction of voice and video over LTE (VoLTE), video telephony applications allow simultaneous transmission of video and audio. Both video and audio functionalities need to be verified during development and quality assurance. Customers are also demanding more audio and video testing capabilities in a single test and measurement solution for complete testing functionality in overlapping applications.

The R&S®VT-K2111 A/V distortion analysis option allows users to assess video quality. Audio quality is evaluated with the help of the perceptual objective listening quality analysis (POLQA) and perceptual evaluation of speech quality (PESQ).
