Video quality estimation apparatus, video quality estimation method, frame type determination method, and recording medium

摘要

A frame type determination unit (15B) counts, as the frame data amount of each frame, the number of TS packets included in the frame based on a frame start position included in an input TS packet of video communication, and determines a frame type based on the large/small relationships between the frame data amounts of the frames. A video quality estimation unit (15C) estimates the video quality of the video communication based on the frame type of each frame obtained by the frame type determination unit (15B), the frame structure (14A) of an elementary stream read out from a storage unit (14), and a TS packet loss state detected from the TS packets of the video communication.
