Overview
NDS3542A V2 4K encoder modulator is DEXIN’s new breakthrough all-in-one devices which integrate encoding (H.264 /H.265) and modulating to convert V/A signals into Digital RF output. It is equipped with 4 HDMI channels input and 1 ASI 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 latency has been greatly reduced to achieve an extremely low value from the encoding progress to the decoding terminals. It adopts an inner drawer-type structural design which greatly facilitates the change of encoding modules as needed. The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Specifications: *2 or 4 HDMI inputs with H.265/h.264 video（4K encoding for H.265 only）; HEVC/ H.265 , MPEG 4 AVC/H.264; 255 input per channel; *IP output over UDP, RTP/RTSP from the 100/1000M self-adaptive data port; *Excellent modulation quality; RF output level; RF output level; RF output level
