OTV-ENC1 SRT Encoder Decoder

    NDI SRT HLS RTMPs Encoder Decoder with USB Video Recording



OTV-ENC1 NDI|HX H.265 HDMI Video Encoder Decoder with USB Video Recording. It features high performance, low latency and low bit rates for IPTV/OTT systems, realized Video & Audio real-time transmission via internet, and adopts state-of-the-art compression technology of H.265 HEVC. As encoder, it support video source through the local USB files,HDMI video or over Ethernet in normal protocol of HTTP/HLS/RTSP/RTP/UDP/RTMP/RTMPS, or in NDI|HX streams (Optional) for use with other NDI|HX compatible systems, convert it to IP. Meanwhile It support Decoding function, IP streams or NDI|HX streams input H DMI out.

OTV-ENC1 NDI|HX H.265 HDMI Video Encoder Decoder Encoding support 1 channels of 1080P H 265 video and stereo audio simultaneously, built-in self-developed full frame

rate de-interlacing technology (e.g. 1080i@60 input, after de-interlacing is 1080p@60, rather than other manufacturers of 1080P@30, which is particularly important for high quality demand live Event ).

OTV-ENC1 NDI|HX H.265 HDMI Video Encoder Decoder be applied to education, health care, IPTV, conference, remote education, news interview, court, public security, banking, transportation and other industry application.

Key Features:

  • Support NDI HX encoding and NDI HX decoding functions. At the request of NewTek, the copyright owner, customers who need to use the complete NDI functions need to purchase NDI Authorization separately. If no authorization, only can be use 30 minutes but no affect on other functions.

  • Audio encoding formats are AAC, MP3, PCMA, etc, Support live stream protocol SRT,HTTP, HLS, RTSP, RTP,RTMP of flow push, RTMP pull flow, UDP, Multicast network protocol etc. And the one same channel can enable all network streams at the same time.
