Overview:

OTV-DC20 HDMI/HD-SDI/VGA Streaming Media Decoder is a network (IP) HD video decoder with high performance. OTV-DC20 could get IP-Camera from network, stream media server or stream media on OTT-EC serial encoder (based on RTSP, RTP unicast or multicast, then outputs video and audio to SDI and HDMI/VGA/DVI through self-adaptive decoding. OTV-DC20 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.

OTV-DC20 support decoding simultaneously for 2 channels HD video up to 1080p60, with functions of self-adaptive decoding and smart control 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 package loss, OTV-DC20 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. OTV-DC20 supports H.264 encoding video with bit rate high up to 40Mbps and decoding output of AAC-LC/G.711 encoding video.

OTV-DC20 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 and HDMI signal, then synchronously transmitting with video.

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