Digital Terrestrial Television Receivers for the DTMB system (IEC 62753:2015)

This International Standard specifies the basic functions, interfaces, performance
requirements and test methods of the receivers for the Digital Terrestrial/Television
Multimedia Broadcasting (DTMB) system. This standard can be applied to digital television
terrestrial receivers carrying multiple SDTV programs or HDTV programs for both mobile and
stationary receptions.
