VIDEO COMMUNICATION QUALITY ESTIMATION DEVICE, METHOD, AND PROGRAM

摘要

A multi-modal quality estimation unit (11) estimates a multi-modal quality value (23A) according to an audio quality evaluation value (21A) and a video quality evaluation value (21B). A delay quality degradation estimation unit (12) estimates a delay quality degradation amount (23B) according to an audio delay time (22A) and a video delay time (22B). A video communication quality estimation unit (13) estimates a video communication quality value (24) according to the multi-modal quality value (23A) and the delay quality degradation amount (23B).
