ETSI EN 303 372-2适用于卫星广播接收的室内设备（IDU）。室内机通过输入接口接收来自卫星并由室外机（ODU）处理的信号。它执行载波选择、解调、音频和视频解码。部分IDU功能可与ODU集成。在这种情况下，本文件适用于这部分功能以及IDU中的其余部分。室内机可与家用电视接收器集成。本文件包含证明无线电设备有效使用并支持有效使用无线电频谱以避免有害干扰的要求。

ETSI EN 303 372-2 applies to indoor units (IDUs) for satellite broadcast reception. An indoor unit gets on an input interface the signal that has been received from satellite and processed by the outdoor unit (ODU). It performs carrier selection, demodulation, audio and video decoding.Part of the IDU functionality may be integrated with the ODU. In that case the present document applies to this part of functionality as well as the remaining part in the IDU. The indoor unit may be integrated with a domestic television receiver.The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
