Affordable Digital HD Video Transmission made easy!

Ez-WifiBroadcast is a radically simple digital data transmission system. A bidirectional data link is established using commercial off-the-shelf hardware like WiFi modules and a pair of Raspberry Pi computers. Coupled with special software this unique system allowes transmission of low latency HD video, telemetry and control data between endpoints. In comparison to a classical wireless connection Ez-WifiBroadcast tries to imitate the famous properties of an analog link like graceful signal degradation and no association between the endpoints.

EZ-WifiBroadcast system is based on Befinitiv's Wifibroadcast project but since then has signicantly evolved and matured thanks to the active support from open source community members.
