Abstract
This invention provides a video quality estimation apparatus (1) including a packet analysis unit (10) that derives the bit rate of an encoded video packet contained in an input packet, and the bit amount of the encoded video packet for each encoded video frame type, a video subset frame characteristic estimation unit (11) that derives the frame characteristic of each video frame type from the bit rate derived by the packet analysis unit (10), and an encoding quality estimation unit (12) that derives, based on the bit rate and the bit amount of each video frame type, a video quality value quantitatively representing the quality of encoded video data that is affected by encoding degradation. The video quality estimation apparatus performs more accurate video quality estimation by taking account of the bit amount of each video frame type.
