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 capablility.
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 non-BDA interfaces

Comments off

Here are some interface libraries to a non-BDA DVB devices. Use them only if the BDA version of the driver for that device is not available. Please note that I cannot test them from various reasons: missing PCI interface from new motherboard or I don’t own the device anymore.

  • Dev_DvbWorld.int – v2.3.0.198
    – access the hardware using vendor’s DwUsbApi.dll which must be present in AltDVB directory
  • Dev_Pinnacle.int – v2.3.0.200
    – for older Pinnacle PCTV Sat/ PCTV 400i / etc.
  • Dev_SkyStar2.int – v2.3.0.770
    – fixed DiSEqC command when using driver >= 4.4.0
    – config dialog built without VCL
  • Dev_TTBudget.int – v2.3.0.294
    – need WDM drv. 2.19h (28.11.2006)
    – you have to copy “ttlcdacc.dll” (ver. >= into ..\AltDvb\Devices\
    – tested with S2-3200

Dev_BdaDriver – Version

January 19, 2020 Comments off


  • added DiSEqC, PLS & MIS support for TBS PCI-E devices
  • fixed DiSEqC for TBS USB devices

I think there is a driver issue with some TBS devices. After sending a DiSEqC command, the 22KHz tone is automaticaly set to ON causing the LNB to switch into HI band and loosing then transponder signal, if previously was in LO band. Of course, this only happens if the DiSEqC command is sent after the tuner is locked on the transponder, and is not noticeable if the DiSEqC commands are sent before setting the tuner.

I have tested on TBS-5520SE (USB) with driver v1.0.0.7 and TBS-6522 (PCI-E) with driver v1.0.1.2.
(many thanks to Mr. satelescu/satesco for borrowing the TBS-6522 device)

The setting TbsFix22KHz=1 from Dev_BdaDriver.cfg fixes the issue by sending TBSACCESS_22K with TBSBURST_OFF after the DiSEqC command, if the current TP is on LO band.

I already notified Mr.Steven from TBS Technology and he will verify the issue.

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 completly 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 is bundled into 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 “Dev_Bda2Driver.int” 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.
