We are broadcasting the lIve-streams on three DVB-T transmitters in different modes each: One frequency with MPEG2 on standard DVB-T, one frequency with H264 on standard DVB-T and a third frequency with H264 encoding DVB-T2. We are not using HVEC (H265) encoding on DVB-T2 (like Germany is planning in the future) as there are practically no H265 DVB-T2 receivers available at the moment.
We use R&S Low Power Transmitters SLX8000 with a Tandberg MAS400 ASI/IP Gateway.
Antennas are self made Groundplanes with vertical polarisation with 0 dB gain.
Channels
The german regulatory authority (Bundesnetzagentur) assigned us following channels:
- Ch 35 - 586 MHz DVB-T MPEG
- Ch 40 - 626 MHz DVB-T H264
- Ch 49 - 698 MHz DVB-T2 H264
Maximum ERP Power are 37.8 dBm / 6 Watt
