BATC announced that they had run out of DATV-Express boards and would no longer sell any more through the BATC Online Shop. The DATV-Express project team wants to thank BATC for their tremendous support and their help in getting sales of the boards started “from the beginning”.

The project team has made a decision to have an EU distribution centre ready by the new year. So anyone that wants their board shipped from inside the EU should hold off ordering until we have moved the stock. When ready, EU orders will be entered like normal orders on the DATV-Express-Project website www.DATV-Express.com using the PURCHASE-A-BOARD link at the top of the main page…but will ship from within the EU.

Charles G4GUO has been tweaking the DatvExpressServerApp software for Windows by tweaking the Windows Installation program and fixing a few bugs. Charles has just changed over to a new Windows-installation utility called InnoSetup. The InnoSetup package will allow the DatvExpressServerApp software to be “installed” and also “uninstalled” on a Windows machine in a more conventional manner.

Slowly but surely, Ken W6HHC (who recently has way too many conflicting interests for his spare time) is switching over to begin testing the new DatvExpressServerApp-with-InnoSetup-installer software package. The plan is to provide this new software package on the project web site as an alpha-release download.

Hi Ken,

Playing with the Logitech C920 and Lubuntu on the Odroid, I can use the camera with "GUVCVideo" Application.

DATV_Express board finds it as hardware, but can't get the ticked boxes on the Main tab of DVB Transmitter software.

Also played with Express_Server, and it finds camera, get full set of green lights on Tutioune but no pic or sound,

but it's not happy calculating the bit rate, as far as I can see?

Wonder if you have had and success in this area, also playing with windows server, MainConcept filters and Graph Studio,

wish I could find where they hide all the registry settings? where we change bitrates and pids etc

Hello Peter,

Express only supports Hauppauge PVR capture devices because Express has no software codecs in it.
If you want to transmit DATV with your web camera you would have to use FFMPEG and then output the
stream to Express via the server code available on Github. Have a look at what Chris MW0LLK has done

With the Windows setup the Mainconcept mux does not save it's parameters so the PIDs will all be incorrect.
They will have to be manually altered.
