1. DVB-T demodulator: the global passport for terrestrial digital television
- Representative models: RTL2832U (support DVB-T/T2), RTL2838UH (4K HDR enhanced)
- Technical features:
- Supports COFDM modulation, adapting to complex multipath environments (e.g., urban high-rise clusters, mobile vehicle scenes).
- Integrated adaptive equaliser, stable decoding even under -95dBm weak signal.
- Application: Suitable for home receiver, car TV, portable terminal.

2. DVB-C demodulator: the efficient heart of cable TV network.
- Representative models: RTL2840C (compatible with J.83 Annex A/B/C), RTL2843C (DOCSIS 3.1 convergence programme)
- Technical Breakthrough:
- Supports 256QAM high-order modulation, spectrum utilisation increased by 30%.
- Built-in intelligent power management module, standby power consumption as low as 50mW.
- Application Scenario: Cable TV operator network upgrade, hotel IPTV system, commercial building multimedia distribution.

3. DTMB/CTTB demodulator: localisation benchmark of standards
- Representative model: RTL2872D (DTMB-A), RTL2876D (CTTB enhanced)
- Localisation Adaptation:
- Fully compatible with GB 20600-2006 standard, supports single carrier/multi-carrier hybrid mode.
- Optimised anti-noise algorithm for complex electromagnetic environment (e.g. 5G base station interference).
- Strategic value: help 4K ultra-high-definition channel landing, rural ‘household access’ project, emergency broadcasting system construction.
