Patent ID: 7936916

Claim:
A video quality measurement (VQM) system for a video stream, comprising: an image metric measuring module to measure an image metric of the video stream; a packet metric measuring module to measure a packet metric of the video stream; a neural network VQM module coupled to the image metric measuring module and the packet metric measuring module to calculate a video quality metric of the video stream based on the image metric and the packet metric; and a VQM test-bed coupled to the neural network VQM module to determine and validate the architecture of the neural network VQM module; wherein the video stream is a MPEG4 video stream and the packet metric is related to packet loss rate of I-frame, packet loss rate of P-frame, and I-frame rate; and wherein the packet metric measuring module further comprises: a frame type deciding unit for determining the type of the received MPEG4 image frame; a packet loss rate of I-frame calculating unit for calculating the packet loss rate of I-frame; a packet loss rate of P-frame calculating unit for calculating the packet loss rate of P-frame; and a I-frame rate calculating unit for calculating the I-frame rate.
