[中文适用范围]： 本国际标准描述了用于在 VHF 频段 III 中操作的地面和有线接收的消费设备的数字音频广播 (DAB) 接收器特性。用于特定应用的专用接收器不属于本标准的范围。该标准描述了不同类别和类别的 DAB 接收器的特性，例如标准和多媒体接收器以及家用、汽车和适配器接收器。 [外文原描述]： 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.
