Ndi Multi-Channel HEVC encoder of ENC18 IPTV head suppots SRT H265 encoder live streaming protocol

Explain the importance of encoder in IPTV solution, the core of streaming video and audio encoders is to provide high quality and stable live streaming, then send it to the streaming service for distribution, and finally the client accesses the streaming server to watch the program. Because it is a very important source in the whole scheme, it is necessary to analyze the streaming media video and audio encoders.

1.Hardware video encoders use independent SOC chips to encode and push video and audio signals, ENC18 Ndi Multi-Channel HEVC 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,It can provide 100ms low latency live streaming.As for video and audio quality, it mainly focuses on encoder main chip provider, please check Chip algorithm evaluation. (I recommend ENC18 SRT H265 encoder live streaming ,As shown in figure 3.1)

2.The software encoder adopts the combination of video and audio capture card and computer, video and audio signals are encoded and pushed by computer software. 10 years ago, our client would build such a system, but now it is basically on the verge of obsoletion. The advantage of this system is that video has good quality with low code rate and flexible extension function, but running on high code rate or H 265 coding algorithm requires a lot of computer configuration requirements, and it is very unstable to use Windows operating system at the same time,It cannot provide low latency live streaming.(As shown in figure 3.2)

ENC18 ndi Multi-Channel HEVC encoder is a 18 channel of 4K embedded video and audio hardware encoder,It can be converted into a 26 channel IP transcoder. 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 18 channels of 3840×2160 30fps 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, ENC18 h 265 video compressor 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.

ENC18 multi-channel HEVC video encoder applies 1U design is easy to carry, embedded OS(embedded operating system), supports 7×24 hours non-stopping work. Its platform is based on BS configuration structure; management and configuration are done by this web-page in the long-distance without being supervised by human.

ENC18 h 265 video compressor supported h 265 and h 264 standard,  Supported audio encoding formats are AAC, MP3, PCMA, etc, Support live stream protocol SRT,NDI,HTTP, HLS, RTSP, 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.

ENC18 multi-channel HEVC video encoder support timing recording and network storage,IPTV head h 265 video compressor of ENC18 supports 26 channel real-time transcoding function.
