This Recommendation presents an objective picture quality measurement framework that works as an automatic quality monitoring system in a digital television network by use of in-service test signals. In-service test signals are applied for applications such as video transmission between different two locations. This method is applicable for either compressed or uncompressed transmission; however, this method is practical especially when lossy compression is applied in the transmission chain, because compression degradation masks degradation caused by test signals themselves. When PSNR is to be estimated by the method, it is a good idea to adapt the intensity of the test signals to the compression bit rate (see Appendix III). This method is applicable, for example, to transmission between studios and to broadcasting to end receivers.
