Naked hardware #14: DVB-T2 USB TV Stick HD-901T2

Teardown HD-901T2 DVB-T2

DVB-T/T2/C FM+DAB+SDR
That is relatively young device as it appeared to market around 2 months ago, beginning of September 2013. It is sold without any real brand, though model number HD-901T2 is mentioned by some sellers. USB interface advertises manufacturer string "astrometadvbt2" and product "dvbt2". From manufacturer string we could guess it is AstroMeta Co. - or not. Own USB ID, 15f4:0131, is assigned to that device by device vendor.

That DTV stick is basically almost same than RTL2832U + R820T reference design, but there is one big difference - external DVB-T/T2/C demodulator. It is also a little bit bizarre as it advertises unofficial SDR (provided by RTL2832P).

Looks like device is build upon some new Realtek reference design, whilst it may different somehow. Windows drivers are near Realtek drivers, but those are still customized (?) for that device. Drivers that are coming with the device, are in a quite bad shape as even standard BDA interface didn't work. Own Windows application is only application which could be used currently.

Initial Linux support is about to go in Kernel 3.13, or in a bad luck 3.14 as Kernel merge window is very near to open. Kernel driver has only DVB-T support at the moment, due to missing external DVB-T/T2/C demodulator driver.

Key components:
Realtek RTL2832P
Panasonic MN88472
Rafael Micro R828D

Hardware internals

RTL2832P, MN88472, R828D
All relevant components, RTL2832P, MN88472 and R828D, could be found from that side of PCB. Visible crystal near R828D is 16.000 MHz, clock source for R828D. Other side of PCB has 28.800 MHz crystal for RTL2832P and 20.500 MHz crystal for MN88472.

RTL2832P is same chip than RTL2832U, but it has extra TS (transport stream) interface to connect external demodulator. Shortly, RTL2832U is USB interface and DVB-T demodulator in one package. For more information about that chip see my old blog posts of RTL2832U.

Panasonic MN88472

Panasonic MN88472
MN88472 is DVB-T/T2/C demodulator. It is very first time when that chip is seen on PCTV device. Earlier DVB-T2 capable demodulators used for PCTV devices are Sony CXD2820 and Silicon Labs Si2168.

There is own 20.500 MHz crystal, which offers clock source for demodulator. TS bus (between RTL2832P and MN88472) is hardly visible. It is not clear whether it is connected using serial or parallel bus, though serial mode could be good guess, as there is no 8+ wires clearly visible needed for parallel mode.

I2C control bus is connected to RTL2832P I2C adapter.

Rafael Micro R828D

Rafael Micro R828D
R828D is Low-IF hybrid silicon RF tuner. That tuner is very similar than R820T tuner used earlier for some RTL2832U devices. R828D is flagship model, whilst R820T is reduced to DTV terrestrial only reception. There is own 16.000 MHz crystal, which is a little bit odd as older RTL2832U + R820T designs used shared clock source from RTL2832U.

Tuner IF bus is connected to both MN88472 and RTL2832P. Control bus, I2C, is wired to RTL2832P I2C adapter only (RTL2832P I2C adapter is property of integrated RTL2832 demodulator).

PCB backside



Only chip visible is 24C08 8k serial eeprom. It contains USB configuration information, e.g. device USB ID and manufacturer strings. It is connected to RTL2832P via I2C.

Black 3-leg component is IR-receiver. It is connected also to RTL2832P, which offers RAW mode remote controller signals.

Crystal "Y2", 22.500 MHz, for MN88472.
Crystal "Y3", 28.800 MHz, for RTL2832P.

  5. I know there is one person hacking with MN88472 Linux driver and it is not me! What I quickly tested (against generated code from the sniffs) I was able to view DVB-T2 without any changes to R828D tuner driver. For DVB-C it seems like some changes are needed also for tuner driver. But biggest part is of course that totally missing demod driver.

    1. Plain DVB-T support went Kernel 3.13. That DVB-T support was easy to add as it is quite same device than RTL2832U + R820T (but without MN88472), having integrated RTL2832 DVB-T demodulator. DVB-T2 and DVB-C support is not that easy as new chipset driver for MN88472 demodulator is needed. Also, writing multimode (DVB-C/T/T2), demodulator driver is about same than writing 3 separate demod drivers. All those mentioned DTV standards differs so much from each others, which means there is typically just 3 different demodulators in one package (3-in-1 demod).

      So it works with DVB-T only starting from 3.13. DVB-C/T2 will come later...

      hmm, what you mean about DVB-C? What I have tested on XP it works.

      I also did some Linux DVB-C tests as someone promised to pay for DVB-C support, but he haven't replied me almost 2 weeks ago :-( Basically Linux DVB-C works, but only for QAM128 and lower. QAM256 is not working as RTL2832U cannot feed that large video stream. Fortunately there is PID filters on RTL2832 to filter stream smaller, but it those PID filters needs to be implemented to Linux driver. There is two other persons working on it.

    1. I did some hacking for DVB-C, as some moron promised to pay for DVB-C support, but when I asked money he disappeared. I have no much motivation continue as there is more interesting things to do. DVB-C mode works up to QAM128, QAM256 will not work as stream is too wide. The trick to get QAM256 must be PID filtering, but I was not able to succeed with it for some reason. Anyhow, tree is here waiting for developer (I cannot give much help, so developer should be able to gather needed info itself):

  15. This seems like rather badly supported device quickly hacked together... eBay is full of this and it's cheap, but if it doesn't work, that's not much of use then. Is PCTV 290e still the only USB DVB-T2 tuner that works reliably under Linux? It's a bit pricy and availability is bad (Amazon tells me 1-2 months of delivery time), but maybe it's better to step in the queue.

    1. PCTV nanoStick T2 290e is almost only DVB-T2 capable stick on the market that is supported on Linux native. However I remember someone added another stick recently, which was also using same demodulator. Sony CXD2820 is only DVB-T2 capable demod that having Linux driver and it very old... There is some DVB-T2 sticks having newer Silicon Labs chipset, but no open driver.

    2. PCTV has just published a new product: tripleStick 292e, which looks exactly the same as 290e, but internals are probably different. http://www.pctvsystems.com/Products/ProductsEuropeAsia/Hybridproducts/PCTVtripleStick/tabid/308/language/de-DE/Default.aspx

  17. получил вчера такой девайс с eBay. Установил драйвера и программу. После сканирования TV диапазона (Москва) никакого списка каналов не сформировалось. Хотя во время скнирования было видно как изменялся уровень сигнала. Но поднимался максимум до 8 из 10 на частоте 562 МГц, на остальных (там где есть вещание) максимум 6 из 10. Может не хватает силы сигнала? Раз ничего не распознал? Есть, кто тоже из Москвы? Пробывал сканировать с предустановками для России, UK, France. Если зайти в расширенные настройки (клавиша e), то попробывал отсканировать одиночный канал (тот самый 562 МГц). Но тоже безрезультатно.... Или просто напросто не рабочий тюнер?

  20. Hi Antti,

    I included merbanans RTL2832filter support code into your latest code.
    https://github.com/merbanan/nm88472/commit/5919b2057584b0ac963fba96aae9dfe2308cfc2f

    After some tiny changes I was able to compile and run the code. Unfortunately I doesn't see any effect (256-QAM is still not really working). I know that the driver is calling the function rtl2832u_pid_filter() to set PID filter and I would like to verify if the code is correct. Where I can find more information how the RTL2832U is working e.g. I2C commands?

  23. Hi Antti,
    I used the RTL2832U chip in the DVB-T dongle as SDR-RTL Mode S (1090MHz) receiver and read the I/Q samples as USB bulk-in with 2Msps.
    My question is can I read the data from the RTL2832P directly after modulation at a higher speed?

    ReplyDelete
    Replies
    1. Very max is 3.2Msps, but it could drop some samples as it is very near hw limits. I suspect chip USB buffers are so small that even minor delay on USB transfers and you will lose some data as FIFO buffer overflows. When I did some tests I found that disabling chip IR interrupts helps... so it might give idea how critical timing is at that high speed (chip handles remote controller interrupt and even it causes so much delay that FIFO overflows). Also it was needed to use very large and many USB URBs to get data from chip in order to avoid any delays.

  25. Hi Antti,
    I'm wondering if I can capture a full QAM256 ~40Mbps mux with the T292e, working well with a T290e but having problems buying more T290s! You made a comment before about needing a pid filter due to hardware limitations at QAM256 rates, is this really a hardware limit or does it work ok now the driver is a little more mature?

    I'm recording the BBC Ultra HD World Cup test transmissions so need to capture whole mux to be sure as not much understands the h.265 video, the video is 36Mbps anyway.

      so I will attach -v in the Makefile and run it again.

      So the make is running:
      CC [M] /home/debian/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0/RTL2832-2.2.2_kernel-3.0.0/rtl2832u.o

      without errors and similar so should produce a rtl2832u.ko IMHO.

      I found that the vermagic of the module produced was incorrect - it should be
      vermagic: 3.4.67-sun4i+ preempt mod_unload modversions ARMv7 p2v8

      instead get:
      vermagic: 3.4.67-sun4i preempt mod_unload modversions ARMv7 p2v8

      In trying to track this down I have not found the source of sun4i versus sun4i+. Is it being determined by scripts/setlocalversion by any chance since .config and Makefile look correct.

      So concluding:Along with some other advice I have concluded that the module is incomplete for device 0bda:2838 in kernel 3.4.x for the Allwinner A10 architecture and the best hope is for kernel 3.15
      at some unknown future date. If you can point me in a direction that fixes that I would be very grateful.

  32. I have noted that only some of the RTL2832U devices are 0bda:2838 like mine where most are 2832.
    I have added the vendor:product id to the dvb-usb-ids.h file but still get no rtl2832u.ko from the compile.
    Do I need different include files or just a patch for the 3.4 kernel? I have read that 3.7 kernel adds support for 2838, along with E4000, FC2580 and other tuners so maybe this device is not going to work on 3.4 kernel?

    Thanks

  33. Hi guys! I have recently bought this product and I have some problems with DVB-T2 channels. Tuner finds all channels but there is no picture (green picture), only sound. I can record it and watch it later normaly, but there is no live picture. Help?

    1. Which tree you were using? Driver has only minimal DVB-C support, no DVB-T2 at all. It should not be possible in any case to see DVB-T2 channels nor channel names.
      Or are you speaking Windows driver?

    2. I'm using Windows 7 x64. I've installed the newest drivers from AstroMeta site but the problem didn't go away. I'm from Serbia if that helps you.
