Xbox One Digital TV Tuner…on Windows

June 1, 2021 Comments off

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 Dev_UsbDirect page.

Dev_UsbDirect – An experimental hardware interface for AltDVB

May 30, 2021 Comments off

This piece of software started as an experiment more than 13 years ago when I bought my first DVB USB device: Siemssen Opera DVB-S1. The existing driver did not work very well so I thought of using a universal USB driver from Cypress and accessing the device directly. I disassembled the device, noted the IC used and started looking for documentation. The programming of the demodulator STV0299 was simple and the full datasheet was available on the internet. Excited about the speed of new interface, I later added support for two other devices I own: DVBWorld Dw2102 and Dw2104. Later on, I replaced the Cypress CyUSB generic driver with WinUSB to be more compatible with recent windows versions.

For those brave enough to try this interface, here is the download link and a short installation guide:

Dev_StreamRead – AltDVB interface to StreamReader.dll

May 17, 2020 Comments off

I wrote a simple interface to the StreamReader.dll library. Most of the tuner parameters (Modulation, FEC, MIS/PLS, Rolloff, Pilot) are sent to the dll if there is a correspondence between my internal coding and values expected by library. Raw DiSEqC is also supported,if hardware has this capability.
Download and extract it into the .\AltDVB\Devices folder.

You also have to download the StreamReader.dll and extract it into AltDVB folder.

Many thanks to Crazycat for his nice and complex piece of software !

ICD2 programmer adapted for 64-bit Windows

April 21, 2020 Comments off

Microchip made major changes to the 64-bit driver for the ICD2 compared to the 32-bit one, so it took me a while to adapt the application. Now it works OK regardless of the driver used.
I also added the -V option to the command line in order to program the microcontrollers powered from another voltage source. (default is to set VDD = +5V). More command line options here

AltDVB Device Server

April 20, 2020 Comments off

This is an application used to remotely access a DVB device over TCP/IP. To install it extract the archive content into your AltDVB’s directory. The server is using one of the available interface libraries from .\Devices\ directory to access the DVB hardware. On network side, two TCP ports are used: one for commands (37000) and one for data (37001). You can change it by editing AltDVB_DevServer.cfg.

Warning: Be sure to stop the server if you want to use the same device directly in AltDVB !

To connect AltDVB to a remote server you have to manually edit Dev_Network.cfg. Please note that there is no autoreconnect feature: if the TCP/IP connection to the server is lost you have to restart the AltDVB.

AltDVB version v2.3 – Mr. Orbita Edition

January 4, 2020 Comments off

I’m pretty sure no one expected a new version of the application after so many years of inactivity. I tried once, back in 2016, but I didn’t have enough time to finish some of the started features and prepare a proper release.

This version is largely due to a special person, who through the passion and dedication to DVB technology has convinced me to work again on the rusty AltDVB’s sources. Thank you Mr. Orbita for your support, especially for professional testing and bugs report.

New version highlights:

  • AltDVB is completely portable. Just unpack & run. You don’t need admin rights and you don’t have to register any filters or decoders. LAV Filters v0.74.1-31 are bundled into the archive, but if you are still using WinXP downgrade to LAV Filters v0.70.2 by replacing the content of [.\AltDVB\Filters\LAV] folder.
  • added support for HEVC video and AAC,AAC-LATM and EAC3 audio
  • added support for EVR – Enhanced Video Renderer
  • added support for PLS and MIS. Currently is working only for TBS devices using my Dev_BdaDriver. I have tested on Eutelsat 5°W with TBS-5520SE and seems to be OK.
  • new file format for channel list. You can’t use channel list from v2.2, you have to re-scan ! In the next major version I have plan to move from proprietary format to SQLite database.
  • new file format for transponders. A few .tplist files are found in archive, but better use the [Import] button to download latest transponders.
  • fixed a lot of bugs, added new ones 🙂
  • change log here

There are no breaking changes in device interface. The “” by Diodato and CrazyCat is still compatible, if you wish to use it as alternative to my BDA interface. I will prepare an SDK to include the new changes, if anyone wants to update the library. In the current archive is included only the BDA interface, for the old WDM / USB interfaces I will make a separate download package.
