VIDEO QUALITY ESTIMATION DEVICE, VIDEO QUALITY ESTIMATION METHOD, AND VIDEO QUALITY ESTIMATION PROGRAM

摘要

Provided is a video quality estimation device comprising: a packet analyzing unit (10) that derives the bit rate of an encoded video packet included in an inputted packet, and derives the bit quantity for each of the encoded video frame types of the encoded video packet; a video subset frame characteristic estimation unit (11) that derives the frame characteristics of each of the video frame types from the bit rate derived by the packet analyzing unit (10); and an encoding quality estimation unit (12) that derives a video quality value that quantitatively indicates the quality of encoded video data affected by deterioration in encoding, on the basis of the bit rate and the bit quantity on a per video frame type basis. A video quality estimation device (1) is thereby provided that takes into account the bit quantity on the per video frame type basis, estimating video quality more accurately.
