This device is commonly found on E-commerce sites that ship directly from China. The hardware supports DVB-C, DVB-T and DVB-T2.
Support
DVB-T supported since kernel 3.13, DVB-T2 since 4.6. Drivers being developed support DVB-C with 64QAM/128QAM, but not 256QAM.
Components
Original revision (2013):
- USB interface: Realtek RTL2832P
- Demodulator: Panasonic MN88472 (2014 revision: MN88473)
- Tuner: Rafael Micro R828D
RTL2832P configuration
The RTL2832P has 2 PID filter paths. One for the internal demod and one for a possible external one.
