摘要:
In a content distributing system, a feature amount distributing server 140 includes a processing information generation unit 141 which generates processing information, a feature amount extraction unit 112 which extracts a content feature amount from distributed contents, a processing unit 142 which processes the content feature amount and generates a processed feature amount, a selecting unit 143 which selects an evaluation feature amount from the content feature amount or the processed feature amount, and a distributing unit 144 that distributes the evaluation feature amount to a client 130. A monitoring server 117 has a warning unit which collates the processing information generated by the processing information generation unit 141 of the feature amount distributing server 140 and a quality evaluation value received from the client, and gives a warning when the processing information and the quality evaluation value are mismatched with each other.

A video encoding device includes: a quantization step size encoding unit 11 for encoding a quantization step size for controlling quantization granularity; and a quantization step size downsampling unit 12 for downsampling one or more encoded quantization step sizes to generate a quantization step size representative value. The quantization step size encoding unit 11 predicts the quantization step size using the quantization step size representative value.

A video encoding device includes a planar prediction unit using planar prediction, and a noise injecting unit for injecting pseudo-random noise into a prediction image of a planar prediction block when a reconstructed prediction error value for planar prediction is less than a threshold determined by the size of the planar prediction block. The video encoding device then uses the pseudo-random noise in linear interpolation for calculating the prediction image, based on the conditions under which a gradient distortion occurs, to suppress the gradient distortion.
