This Technical Report specifies an objective JND-based video quality measurement method utilizing availability of the full reference video signal. It is a double-ended measurement identified as the PQR (Picture Quality Rating) method as shown in Figure 1. The PQR method specified in this Technical Report is based on processing 8-bit digital component video as defined by ITU-R Recommendation BT.601 in a manner representative of the response of the human visual system. Due to the perceptual nature of the measurement@ various compression methods can be accommodated (MPEG@ NTSC@ PAL@ etc.). In addition@ the transmission system may include a concatenation of compression methods or be a simple pass-through for evaluation of a codec (encoder/decoder combination). Results of the PQR method are stated in picture quality rating (PQR) values. Normalization of the processed video is required for application of the PQR method defined by this Technical Report. This Technical Report specifies only the PQR method algorithm and the normalization accuracy. See 3.1 for normalization requirements. Purpose This Technical Report provides the technical description of an objective perceptual video quality measurement method that is currently in use within the U.S. While improved methods may be developed in the future@ this Technical Report provides a video measurement method necessary to support the interconnection and interoperability of telecommunications networks at interfaces with end-user systems@ carriers@ information and enhanced-service providers@ and customer premise equipment.
