Xbox One Digital TV Tuner...on Windows

Post by altxro »


Xbox One Digital TV Tuner is a pretty good DVB-C/T/T2 device with a very affordable price (I bought mine for about 8 Euros, shipping excluded). For some reasons Microsoft decided to not release a Windows drivers for it, so it was a logical addition to my newly published Dev_UsbDirect interface.

I tested the tuner on DVB-C and works well for SR 6900 and QAM64, but on QAM256 it loses packets from time to time. (you will see some video artefacts when this happens). I don't know if this is a tuner/demodulator issue or is related to Dib0700 USB bridge and its firmware. Of course, your experience can vary depending on signal quality, USB controller, hardware revision, etc.

If you use the tuner for DVB-T2 terrestrial reception be sure to edit frequency list in AltDVB and change "Delivery Sys" to DVBT2, otherwise will not get the signal lock.

Download needed files and follow the installation guide from www.altx.ro/projects/dvb-usb-direct-interface

Wow! Thanks! :D Got some of these - very cheap devices :mrgreen:

Tested on both DVB-C and DVB-T/T2.

DVB-C: confirmed some small glitches on 256QAM, but basically works fine :)

DVB-T/T2: detected some small issues here:
  1. DVB-T MUX with 7 MHz bandwidth (we are using 7 MHz here on VHF) is not locking
  2. for DVB-T I've got no reading of signal quality, only strength (for DVB-T2 quality is present)
  3. for DVB-T2 - after changing Delivery Sys to DVBT2 I'm able to scan channels, but unable to lock them when changing channels from channel list (like Delivery Sys would not be passed?)
Thanks, it's great to be able to use this devices also under Windows :)

Thank you Mr. Orbita for testing! I will look into the issues related to DVB-T/T2. The truth is I did very few tests on the terrestrial reception, in fact the reason why I did not include this device in the first version was a bug related to DVB-T2 :)

Worry not, it's already a big achievement to have this device working under Windows ;) It offers very fast & stable lock, great for DVB-C scanning and just a day ago I could use these devices only @ Linux and mostly they were covered by dust ;) Thanks ;)

DVB-T2 tuning works if you use "Signal test". So my way to get AltDVB to receive something is to first select the channel, then go to Scan, select the frequency, click "Signal test", let it tune in and then close the window and start streaming. Only Full TS seems to work though.
