Bibliography

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.
