标准范围

IEC 62104:2015（E）描述了用于VHF波段III的地面和电缆接收的消费类设备的数字音频广播（DAB）接收机特性。特定应用的专用接收机不在本标准的范围内。本标准描述了不同类别DAB接收机的特性，如标准和多媒体接收机以及家用、汽车和适配器接收机。第三版取消并取代了2003年出版的第二版。本版为技术修订版。与上一版相比，主要变化如下。本文件已根据DAB系统的发展，尤其是DAB音频服务的引入进行了更新（见ETSI TS 102 563）。为了反映市场趋势，引入了对显示器、文本和数据应用程序的要求。引入了其他测试方法，以允许R。F.使用声学损伤方法，在带有集成天线和/或无外部误码率指示器的接收器上进行测量。第6条已经更新，以反映市场的发展，并为可选功能的实施提供更好的指导。

IEC 62104:2015(E) describes the digital audio broadcasting (DAB) receiver characteristics for consumer equipment intended for terrestrial and cable reception operating in VHF band III. Dedicated receivers for specific applications are not within the scope of this standard. This standard describes the characteristics for different classes and categories of DAB receivers such as standard and multimedia receivers and domestic, automotive and adapter receivers. This third edition cancels and replaces the second edition published in 2003. This edition constitutes a technical revision. The main changes with respect to the previous edition are as follows. The document has been updated in line with the development of the DAB system, and in particular the introduction of DAB audio services (see ETSI TS 102 563). Requirements for displays, text and data applications have been introduced to reflect market trends. Additional test methods have been introduced to allow R.F. measurements to be made on receivers with integrated antennas and/or no external BER indicators by using an acoustic impairment method. Clause 6 has been updated to reflect the development of the market and to provide better guidance for the implementation of optional features.
