This multi-channel HDMI to IP encoder is designed for professional IPTV streaming and video distribution over IP networks. It converts HDMI video signals into high-quality IP streams using H.265 (HEVC) or H.264 encoding, helping reduce bandwidth while maintaining excellent video quality.
The encoder supports up to 48 HDMI inputs, allowing multiple video sources to be streamed simultaneously across LAN or the internet. Each channel generates its own SPTS stream, which can be delivered to IPTV set-top boxes, PCs, smart TVs, or mobile devices.
Multiple streaming protocols are supported, including UDP multicast/unicast, SRT, RTSP, RTP, RTMP, HTTP, and HLS, making this encoder compatible with most IPTV middleware platforms and streaming servers.
Additional features such as logo insertion, QR code overlay, caption support, and audio gain control make it suitable for professional broadcasting environments.
