Outline

Dexin NDS3508D IPTV modulator is a high integration device which is combined with two independent modules. One is IPTV gateway module which is used for the protocol conversion scenarios and streaming media distribution scenarios and it can convert the network IP stream over HTTP, UDP, RTP, RTSP, HLS and TS file into HTTP, UDP, HLS and RTMP protocol. The other is modulator module which supports IP in and IP out and DVB-C/T/ISDBT/DTMB RF out, and it can receive gateway source directly. So NDS3508D achieves IP (HTTP, UDP, RTP, RTSP and HLS) in to RF out in one box.

In conclusion, its high performance makes it widely used in CATV digital head-end, business application, IPTV/OTT system, etc. and it provides various solutions for operators to re-distribute programs.

Key Features

l 1 IPTV gateway module +1 IP modulator module, and they can work independently

l IP in (HTTP, UDP, RTP, RTSP and HLS) to RF out in one box

l Gateway Module:

² 8 Data ports:

First Data port: IP out over HTTP, UDP (SPTS), HLS and RTMP

Data CH1-7 ports: IP in over HTTP, UDP (SPTS), RTP (SPTS), RTSP and HLS

IP out over HTTP, HLS and RTMP (Unicast)

² Transmitting IP to modulator module through Data port

² Support adding scrolling caption, welcome words, boot picture and boot video (this function is only applicable to IP out application and the STB/Android TV must be installed Dexin IPTV APK)

² Support downloading Dexin IPTV APK directly from this module

l Modulator Module:

² IP input over UDP/RTP through Data/Data 1/2 port

² IP output over UDP/RTP/RTSP through Data 1/2 port

² Support 16 DVB-C/8 DVB-T/6 ISDBT/8 DTMB RF out

² Receiving IP from gateway module directly through Data port

l Support IP anti- jitter function

l Control the 2 modules separately via web-based NMS management

l Support TS files uploading through Web management
