DDMALL HEV-4K HDMI over IP video encoder and HDD-20 HDMI IP streaming decoder are designed in mini with built-in HDMI type-A male connector for easy setup. Both are powered by USB connection and H.265 & H.264 Supported. The HEV-4K live encoder supports up to 2160p30/1080p60 HDMI input and up to 2160p30/1080p60 encoding output at video bitrate 64M. It empowers multistreaming function that users can stream to up to 4 live platforms in 1080p60 at 16M simultaneously. The HDD-20 IP video decoder supports up to 2160p60 streaming input and up to 2160p60 decoding output. Both are SRT protocl supported. (the HEV-4K supports NDI/HX2, SRT, HLS, RTMP/RTMPS, RTP, RTSP, TCP, UDP; while the HDD-20 supports ONVIF, SRT, RTSP, UDP).
With embedded H.265 SRT protocol, DDMALL HEV-4K and HDD-20 secure your SRT video in ultra-high quality and low latency.
