US 2001/0026630 A1 · Moving image reception quality evaluation apparatus

Abstract

A moving image reception quality evaluation apparatus has a moving image code reception section 101 for receiving the same moving image code branched by a branch unit 50 as the moving image code input to a moving image receiver 20 just before the moving image receiver 20 receives the moving image code, a moving image decoder section 102 having an equivalent function to a moving image decoder section 202 for decoding the moving image code in the moving image receiver 20 and detecting an anomaly of the moving image code, an image quality degradation evaluation section 103 for analyzing output of the moving image decoder section 102 and evaluating the image quality, and a transmission section 104 for transmitting the evaluation result to the outside.

Dependent claims

A moving image reception quality evaluation apparatus for evaluating the quality of a moving image at the receiving time of a moving image receiver for receiving moving image code output from a moving image transmitter through a network, said apparatus comprising:

a moving image code reception section adapted to receive the same moving image code branched as the moving image code input to the moving image receiver just before the moving image receiver receives the moving image code;
a moving image decoder having an equivalent function to means for decoding the moving image code that the moving image receiver has and detecting an anomaly of the moving image code;
and
an image quality evaluation section adapted to analyze output of said moving image decoder and evaluate the image quality;
wherein the moving image code received by the moving image receiver can be input from the moving image receiver to said moving image decoder.
