IEC 60107-8:1997 电视广播传输接收机的推荐测量方法 第8部分:对D2-MAC信息包设备的测量

The object of this part of IEC 60107 is to define quality parameters and to provide a guideline for measurement on D2-MAC/packet equipments, under uniform and repetitive conditions. The D2-MAC/packet process is specified in EBU SPB 489. The specifications of the limit values of the various parameters of the equipments are outside the scope of this standard; however theoretical curves and references are provided which could be used as a guide for presentation of measurement results. The characterization of signal performances at the radiofrequency interface is difficult to specify and measure; however, correlation elements between RF measurement and baseband measurement are given in annex A. Relations between subjective quality assessment and objective measurement of parameters are developed in annex B.

IEC 60107-1:1997 电视广播传输接收机的测量方法 第1部分:一般要求 广播和电视频率显示的测量

This part of IEC 60107 deals with the standard conditions and methods of measurement on television receivers that conform to the terrestrial broadcast television standards specified by the ITU-R. Such receivers may be used for direct off-air reception, reception via cabled networks or as a monitor for prerecorded video, home movies and games among other applications. This part does not include the measurements specific to the sound channels which are dealt with by other parts: IEC 60107-2, 60107-3, 60107-4, and 60107-5. Measurements for the non-broadcast signals are dealt with by IEC 60107-6. This part of IEC 60107 deals with the determination of performance 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 part of IEC 60107 does not deal with general safety matters, for which reference is required to IEC 60065, or other appropriate IEC safety standards, nor with radiation and immunity, for which reference is required to CISPR 13 and CISPR 20. note: * Former CCIR.
