NDI HX encoder decoder for ENC1 Plus srt streaming 4K sdi encoder conversion live streams

ENC1 Plus NDI HX encoder decoder is a one channel of 4K 30fps(SDI 1080P) embedded video and audio hardware codec. It applies H 265 and H 264 encoding standard.Hardware h 265 encoders use independent SOC chips to encode and push video and audio signals, the srt streaming 4K sdi encoder encoding algorithm is used to transmit it to the network in the form of network packets. Since it only focuses on one thing, it is stable and has very low power consumption. As for video and audio quality, it mainly focuses on encoder main chip provider.


    ENC1 Plus NDI HX encoder decoder is the fastest, easiest, and best way to get video into IP workflows. it delivers the groundbreaking benefits of NDI®, NewTek’s innovative Network Device Interface technology. It captures any HDMI or SDI video source and convert it to IP. In its ultra-portable enclosure. Applications of the srt streaming 4K sdi encoder include hotel TV system, school teaching, digital TV broadcasting, recording system,live video streaming by web celebrity.

    ENC1 Plus NDI HX encoder decoder is a 1 channel of 4k 30fps embedded video and audio hardware encoder and decoder. It applies H 265 and H 264 encoding standard (this standard is a digital video encoding standard made out by TTU-T and ISO). With this encoding standard,it can encode 1 channels of 4k(HDMI) or 1080P(SDI)H 265 video and stereo audio simultaneously. It is inserted with DE-interlacing scanning algorithm, which makes video quality reach the best level. Compared with the present widely used H 264 encoding algorithm, ENC1 srt streaming 4K sdi encoder can save 30-50% of transmission bandwidth and storage space at the same video quality. It has the advantages of supporting international standards, high performance, flexible configuration and strong scalability. It is suitable for radio&TV operators, telecommunications operators, governments of different levels, and school etc.

    ENC1 Plus NDI HX encoder decoder supported audio encoding formats are AAC, MP3, PCMA, etc, Support live stream protocol NDI,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.

    ENC1 Plus srt streaming 4K sdi encoder can push live video stream to NDI,Facebook, YouTube, Amazon, Twitch, Livestream etc. Multiple platforms.
