The Broadcasting Technology Association (BTA) has carried out a series of evaluation tests with the aim of establishing a standard for EDTV-II. Among the tests conducted, this paper will report on the results of subjective evaluation tests of picture quality, susceptibility to noise or interference, and compatibility. In the picture quality test, we confirmed an average improvement of about half a grade in test materials including a still picture and four moving sequences when rating on a seven-grade comparison scale using, as a reference, the current NTSC with an aspect ratio of 4 : 3. However, we observed, the EDTV-II tends to be slightly more susceptible to random noise and interferences than NTSC.
