What is HEVC?
HEVC, also known as H 265, is a next-generation compression standard that offers a number of enhancements over H.264. Compared to AVC (H.264) compression, HEVC is two times more efficient, which translates into maintaining the same video quality at half the bitrate or double the video quality at the same bitrate.
In summary, H 265 will save you on bandwidth overhead and cost, especially if you’re transmitting over cellular networks.
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 4K H 265 HEVC hardware encoder use independent SOC chips to encode and push video and audio signals, the ENC2 pro video codec 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, please check Chip algorithm evaluation. (I recommend ENC2 pro video codec,As shown in figure 3.1)
2.The software encoder adopts the combination of video and audio acquisition 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.(As shown in figure 3.2)
ENC2 Pro 4K H 265 HEVC hardware encoder which is studied, developed and manufactured independently by JLONvision is a 2 channel of 4K 60fps embedded video and audio hardware encoder,It is also a 1 channel decoder and can be converted into a 4 channel IP transcoder(As shown in figure 3.3). 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 2 channels of 4K 60fps 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, ENC video hardware codec 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. The creative full frame rate of 60fps deinterlacing technology is particularly important for live football and game live streaming broadcast.
ENC2 Pro 4k H 265 hevc hardware Encoder applies mini design is easy to carry, embedded OS(embedded operating system), supports 7×24 hours non-stopping work. Its platform is based on B,S configuration structure,management and configuration are done by this web-page in the long –distance without being supervised by human.
