Overview - IEC 62753:2015 (DTMB receivers)
IEC 62753:2015 specifies the basic functions, interfaces, performance requirements and test methods for digital terrestrial television receivers designed for the DTMB (Digital Terrestrial/Television Multimedia Broadcasting) system. The standard applies to receivers delivering multiple SDTV or HDTV services and supports both mobile and stationary reception. It defines RF, demodulation, demultiplexing, transport stream decoding, video/audio performance and a suite of test procedures to verify compliance.
Key topics and technical requirements
IEC 62753 covers the full receiver chain and associated test methods, including:
- Receiver capabilities
- Frequency range, channel bandwidth and acquisition range
- Power supply and interface requirements
- Working modes, program search (automatic/manual) and tuning
- RF front-end and channel decoder
- RF input/output ports and return loss
- C/N threshold, minimum/maximum input levels
- Immunity to adjacent/co‑channel analogue and digital signals
- Resistance to multipath, 0 dB echo and pulse noise
- Demultiplex and transport stream (TS)
- TS data rate handling, PID filters, STC recovery and error control
- Service & Program Information (SI), EPG and subtitle/text presentation
- Video & audio characteristics
- Video acquisition, still-image handling, baseband input formats
- Audio decoding guidance (including informative annex on DRA audio decoder)
- Functional requirements
- Software update, service list, user settings, RTC, power-failure memory
- Test methods and models
- Detailed test set-ups and normative annexes (acceptable error-free criteria, multipath channel models)
Practical applications and who uses IEC 62753
This standard is essential for organizations involved in the DTMB ecosystem:
- Receiver manufacturers - to design and verify DTMB-compliant STBs, mobile receivers and integrated TVs
- Test laboratories and certification bodies - to implement repeatable RF, demodulation and TS compliance tests
- Broadcasters and network operators - to ensure transmitted services are reliably received under target conditions
- Regulators and procurement teams - to specify performance and interoperability for public tendering
- System integrators and OEMs - to validate receiver behavior in deployed networks
Using IEC 62753 helps reduce interoperability problems, improves field performance (mobility, multipath resilience) and supports consistent product certification for the DTMB market.
Related standards
For broader context, IEC 62753 is used alongside other digital terrestrial TV specifications and regional standards (e.g., DVB, ATSC families) and other IEC/ITU documents covering broadcasting interfaces and EMI/EMC test practices. Consider cross-referencing applicable national DTMB regulations when implementing the standard.
