Utilizing An ESP32-C3’s RF {Hardware} For DVB-S2 Video Transmission

Generally the DVB-S and -S2 requirements require a satellite tv for pc someplace in Earth orbit to offer a sign to obtain, however you may also transmit your personal DVB-S2 stream with any RF transmitter for those who’re so inclined. Courtesy of current breakthroughs in utilizing the RF {hardware} of the ESP32 on a uncooked stage, [SP8ESA] has created the ESP32-DATV project utilizing which you’ll broadcast a DVB-S2 sign utilizing an ESP32-C3.

While a bunch PC facet software handles the heavy lifting of turning the enter video sign right into a DVB-S(2) compliant sign, it’s the ESP32-C3 that prepares the samples for transmission earlier than sending them off to its RF block, with no exterior {hardware} wanted.

If this brings to thoughts the concept of utilizing an off-the-shelf DVB-S2 receiver to play again the sign, the frequency vary for DVB-S2 is 10.7 – 12.7 GHz, whereas the ESP32-C3 is proscribed to roughly 2.4 GHz courtesy of it focusing on solely 2.4 GHz Wi-Fi and Bluetooth indicators.

Targeting frequencies as low as 100 MHz might be possible with some {hardware} tweaks, however for greater frequencies the ESP32’s RF block would possibly want an entire overhaul.

Thanks to [ftg] for the tip.
