36、on television (HDTV) displays. Such displays may be used as an integral part of an HDTV receiver for direct off-air reception, reception via cabled networks, or as a monitor for pre-recorded video, home movies and games, among other applications. This standard deals with the determination of perform
37、ance, and permits the comparison of equipment by listing the characteristics which are useful for specifications and by laying down uniform methods of measurement for these characteristics. Performance requirements are not specified. This standard does not deal with general safety matters, for which
38、 reference should be made to IEC65 1 1)or other appropriate IEC safety standards. NOTEMethods of measurement on wide-screen displays for conventional television signals are dealt with in IEC 60107-1. 1.2 Normative references The following normative documents contain provisions which, through referen

If audio channels and loudspeakers are provided, characteristics of the audio channels shall be measu
48、red by the methods specified in IEC60107-2. 2.1.1 Operation conditions Unless specified otherwise in the relevant clauses, both the audio and picture parts shall be in operation and the scanning circuits shall be properly synchronized. The contrast and brightness controls should be set at the standa
49、rd settings specified in2.5. If different values are used, they shall be noted with the results. 2.1.2 Presentation of results Measurement results shall be listed in a table or presented graphically. However, the relationship between two or more quantities is often more clearly represented in a graph than as a table. When the results of a point-by-point measurement for an individual sample are presented as a continuous curve in a graph, the me
