Description
EMI3541 4K encoder modulator is DIBSYS’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
Key Features
- HDMI input with H.265/h.264 video（4K encoding for H.265 only）
- DVB-C/DVB-T/ISDB-T/ATSC RF OUT for order option
- IP output over UDP, RTP/RTSP from the 100/1000M self-adaptive data port
- Support AC3 Pass-through
- Support OSD (logo/QR Code) insertion，logo in PPT form is available
- Support CC (Closed Caption) /Teletext (CC is not available for H.265 at present)
- Excellent modulation quality
- LCN support (Logical Channel Number)
- LCD Screen for easy management
