Product Description

Overview:


Dibview OTV-DC20 ProHD Streaming SDI Decoder is a network (IP) HD video strong decoder with high performance. This decoder could get IP-Camera from network, stream media server or stream media from our OTT series encoders (based on RTSP, RTMP unicast or multicast), then outputs video and audio to SDI and HDMI/VGA/DVI through self-adaptive decoding. This decoder supports SDI signals including HD-SDI (1.485G) standard and 3G-SDI (2.97G), supporting 720p, 1080i and 1080p(maximum 60Hz); HDMI output supporting up to 1080p60Hz HD video signal; VGA supporting maximum UXGA output.


Dibview OTV-DC20 ProHD Streaming SDI Decoder support decoding simultaneously 2 channels HD video up to 1080p60, with functions of self-adaptive decoding and smart control on network delay. Under typical network environment, it can control decoding delay lower or equal to 200ms. Even though low code rate decoding and about 10% network packet loss, this decoder could use image enhancement and fault-tolerant technology to clearly restore encoding video and audio, no obvious distortion, smear, frame loss and mosaic phenomenon of pictures with features of actual color reproduction, clear sound and high fidelity. This decoder supports H.264 encoding video with bit rate high up to 12Mbps and decoding output of AACLC/ G.711 encoding video.

Dibview OTV-DC20 ProHD Streaming SDI Decoder has image scaling capacity, could let after-decoding video larger/smaller converting to adapt to different output video format. Audio could be embedded in SDI signal, then synchronously transmitting with video.

Dibview OTV-DC20 ProHD Streaming SDI Decoder supports ONVIF device detecting discovery. This Decoder provides open source SDK, supporting Windows/Linux/Unix cross-platform and programming second development to realize manage and control for equipments.


Key Features:
