PACKET LOSS CHARACTERISTIC ANALYSIS APPARATUS, METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a packet loss characteristic analysis apparatus, method, and program capable of accurately discriminating video image deterioration due to a burst packet loss.

SOLUTION: A video deterioration discrimination section 12 discriminates invalid packets which a receiver side application terminal 2B cannot normally receive among media packets on the basis of transmission quality information and received quality information and discriminates the presence/absence of the video deterioration from the invalid packets by each invalid packet detection time within a prescribed video deterioration discrimination period on the basis of an assumed burst discrimination condition 13 for denoting a production state of the invalid packets within an optional invalid packet detection time, and a burst discrimination condition determining section 15 calculates an accuracy rate of a result of the video deterioration discrimination obtained from the video deterioration discrimination section by each of different burst discrimination conditions on the basis of a result of a video deterioration evaluation from a quality evaluation acquisition section 14 and determines an assumed burst discrimination condition indicating the highest accuracy rate as a burst discrimination condition 17.
