Recording medium video quality estimation apparatus, video quality estimation method, and frame type determination method,

摘要

The frame type determination unit by (15B), counted as the frame data amount of the frame number of TS packets based on the frame start position included in the TS packets of the video communication with the input constitute the individual frames, these and determines the frame type on the basis of the magnitude relation between the frame data amounts of the frames, the video quality estimation unit by (15C), the read frame type of each frame obtained frame type determination unit in (15B), from the storage unit (14) Based on the loss state TS packet detected from the TS packets of the video communication frame structure of the elementary stream, and (14A),, to estimate the image quality on the video communications.
