Standalone streaming without PC and capture card

NDI’s low-latency and high-definition connectivity technology is perfect for multiple gaming industry applications from a streamer’s home setup to a global e-sports championship live stream. Through NDI, users can directly send audio and video to OBS, vMix for live broadcast, and each PC could be the monitor without any capture card and cable connection.

Powerful encoding and decoding

ZowieBox can encode formats such as H.264 HP/MP/BP, H.265/HEVC MP, NDI, NDI|HX2 and NDI|HX3 as well as SRT, RTMP, RTMPS or RTSP protocols whose bitrate could be up to 50 Mbit/sec. Simultaneously it can directly push streams to multi-platforms such as Facebook, Twitch and YouTube, without a PC. Alternatively, these IP streams could decoder into high-quality HDMI outputs.
