GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner. It's based on the following components: - USB bridge: RTL2832P (contains also DVB-T demodulator) - Demodulator: Si2168-A30 - Tuner: Si2148-A20 The demodulator and the tuner will need firmwares. The Si2148 uses Si2158 firmware. Antti has the firmwares available for download: http://palosaari.fi/linux/v4l-dvb/firmware/ Do note that for DVB-T either of the demodulators can be used. DVB-C and DVB-T2 are only supported by the Si2168 demodulator. The driver will register 2 frontends for the same adapter. Frontend 0 will be the RTL2832 demodulator and frontend 1 will be the Si2168 demodulator. The same tuner is used for both. As a consequence of the above, it's recommended to use application that does implement proper DVBv5 support. For some reason, the old I2C write method sporadically fails. Thus the need for an option to only use the new I2C write method supported by the RTL2832.
