Watching digital TV (SBTVD) in the Linux

Today I got Digital TV working on Linux, thanks to Mauro Chehab.

I used a PixelView PlayTV USB SBTVD (ISDB-T Full Seg):
http://www.pixelview.com.br/play_tv_usb_sbtvd_fullseg.asp

The PixelView uses a DiBcom 8000 chipset. Then the first thing to do is downloading new v4l tree which has support to this chip:

$ hg clone http://linuxtv.org/hg/v4l-dvb
$ cd v4l-dvb
$ make
$ make install

Plug the PixelView PlayTV in the USB, then you should see it:

[100113.248017] usb 1-6: new high speed USB device using ehci_hcd and address 6

Now we need the “scan” and “gnutv” software to see the channels, they are in dvd-apps branch:

$ hg clone http://linuxtv.org/hg/dvb-apps
$ cd dvb-apps
$ make
$ sudo make install

To scan channels we need to have a frequency file, this is the content of my ch_freq.conf:
# UHF channels 14 to 69

Note: This is the generic frequency table for Brazil, based on ABNT standard.

Execute scan to detect channels:
$ scan ch_freq.conf > channels.conf

Then the “scan” should create the channels.conf with content like this (for Belo Horizonte/MG):
BAND:509142857:INVERSION_AUTO:BANDWIDTH_6_MHZ:FEC_3_4:FEC_AUTO:QAM_AUTO:TRANSMISSION_MODE_AUTO:GUARD_INTERVAL_AUTO:HIERARCHY_NONE:250:255:23040

Now it time to watch TV, but unhappily the codec used (H.264) to SBTVD is not supported by gnutv until now, then we will save it to file and use VLC player to watch:

$ gnutv -out file band.mpg -channels channels.conf BAND
Using frontend “DiBcom 8000 ISDB-T”, type DVB-T
status SCVYL | signal aff2 | snr 0015 | ber 00000380 | unc 00000015 | FE_HAS_LOCK

Open a new terminal and execute:
$ vlc band.mpg

This is a snapshot:

Other option is using VLC directly to watch TV, just execute:
$ vlc channels.conf

To see all channels go to Playlist -> Show Playlist and double click the channel you want to watch.

  1. Hi Fabricio,

    I didn’t test it, but I think Windows driver already do that for you.

    To be honest I don’t care about windows 😉

    Best Regards,

    Alan

  2. Olá Alan!
    Acabei de adquirir uma PixelView PlayTV USB Hybrid (http://www.pixelview.com.br/playtv_usb_hybrid.asp). A primeira coisa que tentei, claro, é seguir os procedimentos acima. Mas depois de várias tentativas sem sucesso descobri que o(s) chipset (s) são diferentes (TDA18271 (NXP Hybrid Tuner), 86A20S (Fujitsu ISDB-T demodulator),
    CX23102 (CNXT AV Decoder – 10bit), USB Bridge).

    Procurei na árvore do v4l-dvb e no site linuxtv e não encontrei referências a respeito deste equipamento. Encontrei, contudo, drivers cx231xx e tda18271. Mas mesmo após carregar estes drivers via modprobe, não obtive resultado. Também tentei carregar o driver dvb_usb_cxusb se sucesso.

    Você por acaso sabe de algo a respeito deste equipamento ou se os drivers estão em desenvolvimento?

    Um abraço.

  3. Esqueci de postar as informações do dmesg:

    usb 2-3: new high speed USB device using ehci_hcd and address 8
    usb 2-3: New USB device found, idVendor=1554, idProduct=5010
    usb 2-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
    usb 2-3: Product: Polaris AV Capturb
    usb 2-3: Manufacturer: Conexant Corporation
    usb 2-3: SerialNumber: CIR000000000001
    usb 2-3: configuration #1 chosen from 1 choice

    o interessante é que o idVendor e o idProduct é o mesmo do PixelView PlayTV USV SBTVD, e por este motivo o linux tenta carregar automaticamento o driver do dib0700.

    Um abraço

    1. Eu tb comprei o Hybrid e estou com o mesmo problema. Acredito que dê para forçar o Linux a usar outro drive. Bastaria configurar algum arquivo em /etc/modprobe.d/ ou mesmo nos fontes que compilamos, mas eu ainda estou pesquisando as soluções.

      1. Pelo que eu verifiquei, falta só o driver do Fujitsu ISDB-T demodulator (MB86A20S) e alterar a identificação no usbid, para que ele não tente carregar o dib0700.

        Vamos esperar…

  4. Hi acassis,
    this post was really helpful, but I’m still having problems when scanning for channels. The device is correctly detected and intialized (dmesg says “dvb-usb: DiBcom STK8096GP reference design successfully initialized and connected.”). It’s MyGica S870,
    I live in Buenos Aires, Argentina. We are just beginning to broadcast in ISDB-T so we have very little coverage right now; I expect it to improve vastly.
    Where I live I receive two channels (each with multiple signals, of course), UHF 23 and 43. I used your frequencies file feeding dvb-apps’s scan. Most signals just are ignored with “tuning failed” (which is correct), but on channel 23 it just hangs forever (tried commenting 23 and it hangs on 43).
    My problem is I don’t know where to look to debug this (dmesg doesn’t show anything, so I guess the device is correctly initialized). What logs does dvb-apps keep? stdout doesn’t say anything, it just hangs.

    Thanks in advance,

    nachokb

  5. Amigo estou aqui tentando fazer funcionar um dos dois adaptadores usb que tenho aqui e nem to conseguindo. Você sabe me dizer como posso descobrir qual firmware devo baixar pra eles?

  6. Olá Bruno,

    Você precisa primeiro verificar qual o chip cada um deles utiliza, pois, se eles não forem suportados, de nada adiantaria ter o firmware certo para eles.

    Um abraço,

    Alan

  7. Alan

    Pelo lsusb vi que um tem o enc313alguma coisa que não lembro. E o outro a unica coisa que conseguir ver foi o modelo que dizia ser AVerTv h868. Onde consigo descobrir que firmware suporta um deles?

    Abraços

  8. Alan,

    Entrei nesse link que passou e um dos adaptadores tem la. É esse aoc que é o penultimo listado. Mais na pagina não diz que firmware devo baixar pra ele. AOC ConnecTV Digital o modelo. Pode ajudar ai?

    abraços

  9. Estou tentando instalar EzTV ISDB-T via USB em meu Ubuntu mas não estou conseguindo.
    1) Executando lsusb, é exibido “187f:0201” do dispositivo.
    2) Se executo “ls /dev/dvb”, é exibido “adapter0”;
    3) Se executo “dmesg”, é exibido:
    [19200.388111] usb 1-6: new high speed USB device using ehci_hcd and address 7

    [19201.080634] DVB: registering adapter 0 frontend 0 (Siano Mobile Digital MDTV Receiver)…

    Entretanto, o VLC não consegue encontrar nenhum serviço.

    O que posso estar fazendo de errado?

  10. Ola Jociel,

    Tente usar o gnutv para gravar o video como no exemplo acima. Se funcionar voce saberá onde está o problema, no vlc ou no driver do adaptador de TV Digital.

    Se o gnutv falhar tente usar o strace para descobrir mais informações sobre a falha.

  11. Eu apliquei o comando:
    nogueira@nogueira-asus-eeepc:~$ sudo hg clone http://linuxtv.org/hg/v4l-dvb
    diretório de destino: v4l-dvb
    pedindo todas as mudanças

  12. Ola Antonio Carlos,

    Creio que voce nao instalou o kernel headers no seu linux ou ainda nao efetuou a compilacao e instalacao do kernel Linux.

    Voce precisa dos headers (.h) instalados no seu sistema para efetuar a compilacao do subsystem V4L.

    Um abraco,

    Alan
