Abstract
In Japan, digital broadcasting services via BS are planned to start in 2000. To consider sufficient bandwidth for the transmission, the ARIB carried out subjective assessment tests for existing hardware codecs compliant with the MPEG-2 Main Profile. This paper describes the procedure of the picture quality evaluation for digitally coded picture and shows the results of the subjective assessment tests. The results ahow that approximately 22 Mbps for HDTV and 8Mbps for SDTV are appropriate bit rates for digital broadcasting.
