Abstract

An analytical system for moving picture regeneration is capable of ascertaining an appropriate method of improving the quality of a moving picture by executing satisfactory analysis of the state of moving picture regeneration. With the analytical system for moving picture regeneration, moving picture codes are decoded and regenerated by respective regeneration units. Thereupon, in each of the regeneration units, occurrence of picture freeze is detected by information subunits for picture freeze occurrence, a throughput is detected by throughput monitoring subunits, and delay in input time of the respective moving picture codes is detected by input-time information subunits and sent out to a display unit. Further, a SNR value is computed on the basis of a restored moving picture and a reference moving picture by respective SNR computation units, and a sum of the throughputs of the respective regeneration units is obtained by a total throughput monitoring unit, and sent out to the display unit. As a result, the state of the occurrence of the picture freeze and the SNR, for respective pictures, are detected and displayed concurrently, and also fluctuations in the input delay time and the throughputs for decoding are detected and displayed. Furthermore, a total throughput of constituent units having processing resources in common is detected and displayed.
