摘要

PROBLEM TO BE SOLVED: To provide a technology for reducing computational complexity in reproduction state estimation of video data in a video distribution system for distributing video data to a terminal for the unit of a chunk.;SOLUTION: A video reproduction state estimation device configured to estimate a reproduction state of video data includes: calculation means for calculating, regarding a target chunk arriving at a certain time, the number of temporarily reproduced chunks by adding the number of estimated reproduction chunks each estimated to be reproduced from a time of arrival of a chunk prior to the target chunk to a time of arrival of the target chunk to the number of reproduced chunks at the time of arrival of the chunk prior to the target chunk; and estimation means for estimating the reproduction state by comparing the number of reproduced chunks with the cumulative number of received chunks up to the chunk prior to the target chunk.;COPYRIGHT: (C)2015,JPO&INPIT
