UpdateDVB

updateDVB is a QT based application for stv090x devices like PROF 7301 7500 8000, TBS 5925 5980 6925, Skystar 2 Express HD. It does satellite signal spectrum scan, IQ plot, frequency blind scanning, TS stream analysis and has features for outputting to various video players and streaming via HTTP. In loop mode spectrum scans can be done in 2-3 seconds per scan with most devices making it very useful for pointing your dish and finding satellites. Monitoring signal dB level on the tuning window makes it easy to peak your dish for maximum signal.

ATSC spectrum scan is supported for Hauppauge WinTV-HVR-950Q, 955-Q, Aero-m.

Dependencies

• QT 5.4 or later
• libqwt-6.1
• git
• v4l-updatelee [1]

Installation

Build and install the patched v4l-updatelee DVB kernel drivers. Instructions are in the README. An alternate driver install is media_build_udl.

Copy the frontend.h and dmx.h include files from this tree to /usr/include/linux/dvb/.

Now you are ready to build and install updateDVB. Follow the instructions in the README.

Initial Setup and Operation

On first run choose File => Settings and configure your LNB and Adapter settings. Hit save and close.

Pick your Adapter and LNB config from the lists. Click "Spectrum Scan" to generate a graph of the frequency spectrum. Takes about 4 to 14 seconds slow mode, 1 to 4 seconds fast mode depending on the device. Clicking on any of the frequency "bumps" in the graph pops open the Tuning window. If a signal lock is achieved the signal parameters will be displayed and the TS is parsed and analysed. You can play or stream the entire mux or select a single PMT.
