摘要：A method and system that assesses video quality of transmitted video packetsignals suffering from packet loss and delay. This packet loss and delay can create freezeevents, which are observed as a jerkiness while viewing the video. The system and method
compares the frames in a video transmission to determine freeze events; extracts a set offeatures from the locations of the freeze events and decoded video frames; and mapsthe set of features into a video quality score using a neural network. The video qualityscore provides an assessment of the effects of irregular frame freezes due to packet lossor delay on the quality of the video.
