PCB of the 2017 revision (top)

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):

2013 and 2014 revision look very similar. Probably, the text on the 2013 revision always reads "FM+DAB+SDR", while the 2014 one says "DVB-T/T2/C+FM+DAB". However, seller pictures do not always reflect that change and one could end up buying a random version even years later.

The 2014 revision version is also sold as "Andoer Digital DVBT2 USB TV Stick" or "Docooler YRC1415458446568TZ". Those devices are identical in appearance to the usual Astrometa devices.

TeVii sells a similar device under the name "H630". The case is black. The PCB layout is a bit different, e.g. the IR sensor is in a different position.

In late 2015, a version with analog video input was released, powered by the Conexant CX23102-11Z USB bridge.

In 2017, a clone of the 2014 version with a red PCB (original Astrometa one's is green) also appeared on E-commerce sites that ship from China. The case looks like the H630's, but is white with silver text that reads "DVB-T/T2/C/FM/DAB". This device is shipped in bulk in just a plastic bag with a simple stick antenna, a remote control (21 buttons) and a Mini CD that dates to 09 Jan 2017. Some sellers call it OXA ZC905500 or S SKYEE.

All these models share the same USB IDs.

RTL2832P configuration

The RTL2832P has 2 PID filter paths. One for the internal demod and one for a possible external one.

External ts mode

0x21[3]         enable_ETS, set to enable external ts input
0x21[5]         pass_err, when set reject error packets
0x21[6]         PID_mode, when set reject matched PIDs
0x21[7]         PID_output, when set output data from enabled PID filters
0x22[7-0]       PID_enable, when set enable PID in corresponding register (0-7)
0x23[7-0]       PID_enable, when set enable PID in corresponding register (8-15)
0x24[7-0]       PID_enable, when set enable PID in corresponding register (16-23)
0x25[7-0]       PID_enable, when set enable PID in corresponding register (24-31)
0x26-0x27[12-0] PID_0, PID storage register 13 bits wide
0x28-0x29[12-0] PID_1, PID storage register 13 bits wide
0x2A-0x2B[12-0] PID_2, PID storage register 13 bits wide
0x2C-0x2D[12-0] PID_3, PID storage register 13 bits wide
0x2E-0x2F[12-0] PID_4, PID storage register 13 bits wide
0x30-0x31[12-0] PID_5, PID storage register 13 bits wide
0x32-0x33[12-0] PID_6, PID storage register 13 bits wide
0x34-0x35[12-0] PID_7, PID storage register 13 bits wide
0x36-0x37[12-0] PID_8, PID storage register 13 bits wide
0x38-0x39[12-0] PID_9, PID storage register 13 bits wide
0x3A-0x3B[12-0] PID_10, PID storage register 13 bits wide
0x3C-0x3D[12-0] PID_11, PID storage register 13 bits wide
0x3E-0x3F[12-0] PID_12, PID storage register 13 bits wide
0x40-0x41[12-0] PID_13, PID storage register 13 bits wide
0x42-0x43[12-0] PID_14, PID storage register 13 bits wide
0x44-0x45[12-0] PID_15, PID storage register 13 bits wide
0x46-0x47[12-0] PID_16, PID storage register 13 bits wide
0x48-0x49[12-0] PID_17, PID storage register 13 bits wide
0x4A-0x4B[12-0] PID_18, PID storage register 13 bits wide
0x4C-0x4D[12-0] PID_19, PID storage register 13 bits wide
0x4E-0x4F[12-0] PID_20, PID storage register 13 bits wide
0x50-0x51[12-0] PID_21, PID storage register 13 bits wide
0x52-0x53[12-0] PID_22, PID storage register 13 bits wide
0x54-0x55[12-0] PID_23, PID storage register 13 bits wide
0x56-0x57[12-0] PID_24, PID storage register 13 bits wide
0x58-0x59[12-0] PID_25, PID storage register 13 bits wide
0x5A-0x5B[12-0] PID_26, PID storage register 13 bits wide
0x5C-0x5D[12-0] PID_27, PID storage register 13 bits wide
0x5E-0x5F[12-0] PID_28, PID storage register 13 bits wide

These filters would overlap with the internal ts address space.

0x60-0x61[12-0] PID_29, PID storage register 13 bits wide
0x62-0x63[12-0] PID_30, PID storage register 13 bits wide
0x64-0x65[12-0] PID_31, PID storage register 13 bits wide

Most likely the the external PID filter path has less then 32 pid filters.
