Description
The 4 channel HDMI RF modulator encoder are all-in-one devices which integrate encoding (MPEG-2HD/SD, MPEG-4/AVC H.264 HD/SD) and modulating to convert V/A signals into Digital RF output. The 4channel HDMI encoder is equipped with 4 HDMI (4 SDI optional) channels input and 1 AS I input(optional) and output via 2 ASI ports(optional) and 1 DATA (4*SPTS or 2 or 4 MPTS–as per carrier numbers) output over UDP, RTP/RTSP. The 4 channel HDMI RF modulator features extremely low latency, making it suitable for live broadcasting, surveillance distribution, and real-time video delivery applications.
In addition to DVB-T RF output, the HDMI to DVB Modulator supports multiple IP output formats including UDP, RTP, and RTSP, enabling simultaneous RF and IPTV service deployment. Optional ASI input and output interfaces provide flexible remultiplexing capabilities for professional broadcast environments.
With excellent RF performance, MER≥40dB, web-based management, LCD front-panel control, and support for multiple audio encoding formats, this ISDB-T Encoder provides a reliable and cost-effective solution for digital television distribution.
