Method and apparatus for measuring QoE guaranteed real-time IP-media video quality
First Claim
1. An apparatus for measuring Quality of Experience (QoE) guaranteed real-time Internet Protocol (IP)-media video quality, comprising:
- a receiver receiving a transmission video provided through an IP network service platform and an original video corresponding to the transmission video, and extracting frames of the transmission video and the original video;
a detector comparing the frames of the transmission video and the original video in real time to obtain a difference between the frames of the transmission video and the original video and detecting a matching segment between the transmission video and the original video; and
a measurement unit calculating a QoE parameter using the frames of the transmission video and the original video which correspond to the matching segment,wherein the detector comprises;
a dividing unit dividing the frame of the transmission video and the frame of the original video each into a plurality of blocks;
a mapping unit calculating a brightness of each block to create a rank map;
a distance calculating unit calculating a distance between the frame of the transmission video and the frame of the original video using the rank map; and
a matching segment detecting unit comparing the calculated distance with a predetermined reference distance and, if the calculated distance is shorter than the reference distance, determining a corresponding segment to be a matching segment.
