-[ HackTV - Analogue TV transmitter for the HackRF ]- WHAT'S IT DO Generates a PAL/NTSC/SECAM* video signal from a video file or test pattern. Also supports the older 819, 405, 240 and 30 line standards. Supports NASA Apollo video standards, both colour and mono. Input is any file type or URL supported by ffmpeg. Output can be to a file or directly to a HackRF. Teletext support. NICAM stereo audio. Videocrypt I/II hardware support. Videocrypt S simulator. Partial Nagravision Syster hardware support. * SECAM support is very basic and won't produce a good image. WHAT'S IT NOT DO (yet) There are no filters. Needed for proper audio and VSB modulation. An optional notch filter for the colour subcarrier would be nice. D-MAC / D2-MAC standards. WHAT IT WON'T DO DVB or other pure digital signals. Bring back Firefly. :( REQUIREMENTS Depends on libhackrf and various ffmpeg libraries. * For Fedora (with rpmfusion) yum install hackrf-devel osmo-fl2k-devel SoapySDR-devel ffmpeg-devel * For Debian and related apt-get update apt-get install libhackrf-dev libavutil-dev libavdevice-dev libswresample-dev libswscale-dev libavformat-dev libavcodec-dev INSTALL make make install EXAMPLES # Generate a file containing a PAL baseband signal from a video $ hacktv -o baseband.bin -m pal example.mkv # Transmit a test pattern on UHF channel 31 (PAL System I), 47dB TX gain $ hacktv -f 551250000 -m i -g 47 test # Transmit a test pattern with teletext $ hacktv -f 551250000 -m i -g 47 --teletext demo.tti test # Download and transmit teletext pages from the Teefax service # http://teastop.co.uk/teletext/ $ svn checkout http://teastop.plus.com/svn/teletext/ teefax $ hacktv -f 551250000 -m i -g 47 --teletext teefax test -Philip Heron <phil@sanslogic.co.uk>
