History and updates
Latest version is now hosted on github. All instructions to build is there. Before that, complete SD image could be downloaded but size of download files is huge (1.2GBytes). Updates of image are also hard to maintain. In future, only some released versions could be built based on github sources.
First documentation UglyDATV01 is obsolete
You can look at HamRadio Presentation made at HamRadio 2015.
Main output modes of operation
RF output (formaly named Ugly mode)
RF could be transmitted without any other hardware through a pin of the Raspberry pi header. It is mainly a test mode as QPSK spectrum is not filtered. By using harmonics it could be received directly by a set top box on L band.
Send IP Transport stream to datv express : Datv Express Server (G4GUO).
This output the transport stream to an external modulator. Using this method, it is possible to upgrade an all-in-one encoder/modulator from MPEG-2 to H264.
- DTX1 with dock PCB picture
- SR-SYSTEM Minimod
rpidatv could be configured through several ways
- Command line
- Menu on console (from local keyboard/screen or via network)
- Graphical menu with a touchscreen : video demonstration
- Audio/Video are sent from an external PC running VMix software : Vmix2Rpi
