Abstract:
1. A video quality estimation apparatus comprising: a packet analysis unit that derives a bit rate of an input encoded video packet, and derives a bit amount of an encoded video for at least one video frame type out of a plurality of video frame types; a frame characteristic estimation unit that derives a frame characteristic representing characteristic of the bit amount of each video frame type from the bit rate derived by said packet analysis unit, the frame characteristic including an average bit amount, a maximum bit amount and a minimum bit amount; and an encoding quality estimation unit that derives a video quality value based on 1) the bit rate of the encoded video packet and the bit amount of each video frame type that have been derived by said packet analysis unit, and 2) the frame characteristic of each video frame type that has been derived by said frame characteristic estimation unit, 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.
