ITU-R REPORT BT.1213 PDF

Introduction

The evaluation of digital transmission equipment for video such as codecs, can best be performed on a subjective basis, due to the complex and .adaptive natures of the multi-dimension impairments introduced by bit-rate reduction. CCIR Texts such as Recommendation 500, and Reports 1206 and 1211 provide information on the methods and objectives of this testing. The test pictures (both still and moving) and test sequences for the subjective evaluation of codecs is the subject of this Report, which describes also a recommended set available in digital form.

It is clear that the selection of appropriate test material is a key step in the planning of subjective assessment and that when results are to be correlated between a number of testing sites or groups that the same pictures be used and that they be available at the highest level of quality. The material detailed in this Report meets these criteria and offers the assessor material covering a wide range of criticality.
