Digital CATV Modulator 24 in 1 RTSP HTTP RTMP HLS SRT IP to RF QAM DVB-T DTMB ATSC ISDBT Headend Modulator

Summary

YDS3324I is a cost-effective 24 in 1 IP to ISDBT modulator developed according tov ISDBT standard. It has 3*128 IP inputs. After multiplexing and modulating process, it gives 24 ISDBT non-adjacent carriers (50MHz~900MHz) output through the RF output interface. To meet customers’ various requirements, this device is also equipped with data port for 8 MPTS output over UDP and RTP. This is very adaptable to newly generation DTV broadcasting system.
