| Abstract(in English) | Recently, multimedia communications services have made great progress. Communications quality assessment taking account of customer's opinion is requested for design and management of multimedia networks and terminals. End-to-end communications quality has been studied and standardized in SG12 under ITU (International Telecommunication Union). This paper describes current status of standardization in the ITU for subjective and Objective quality assessment. End-to-end communications quality is rated by loudness rating in relation to opinion rating method. Other impairment factors in networks and terminals are individually defined based on opinion ratings. For the individual impairment factors, this paper describes quality assessment for such multimedia coding as speech and video, and also quality assessment methods for transmission delay and echo in the multimedia networks. |
