• MPEG-2 encoding is done via ffmpeg / avconv. click here for details.
• every mpegts can include multiple video / audio streams
• in hierachical mode, 2 mpegts can be transmitted on the same channel
• https://github.com/siro20/dvbt-encoder/tree/master/app requires a mpeg-ts as input and does all the encoding up to complex baseband signal generation
• D/A and frontend have to be realized in hardware
• hardware includes baseband filters, frequency selection, sample rate selectors and power amplifiers

Project status

• the DVBT-Transmitter has been completed and is running

Source code

• the source code of the DVBT encoder can be found here: https://github.com/siro20/dvbt-encoder

Hardware

• as transmitter the bladerf is used
