Video quality estimation apparatus, video quality estimation method, and program

A non-transitory computer-readable recording medium recording a video quality estimation program for causing a computer to execute

• the packet analysis step of deriving a bit rate of an input encoded video packet, and deriving a bit amount of an encoded video for at least one video frame type out of a plurality of video frame types,
• the frame characteristic estimation step of deriving a frame characteristic representing a characteristic of the bit amount of each video frame type from the bit rate derived in the packet analysis step, the frame characteristic including an average bit amount, a maximum bit amount and minimum bit amount and
• the encoding quality estimation step of deriving a video quality value based on the bit rate of the encoded video packet and the bit amount of each video frame type that have been derived in the packet analysis step, and the frame characteristic of each video frame type that has been derived in the frame characteristic estimation step, using a ratio, for each video frame type, of 1) a difference between the bit amount and the average bit amount to 2) a difference between a) the maximum bit amount or the minimum bit amount and b) the average bit amount.
