H.264 codec and H.265 codec introduction:
H.264 codec and H.265 codec are both video encoding formats. Compared with H.264, H.265 can transmit higher quality network video under limited bandwidth, which means that only half of the bandwidth of the original H.264 encoding can transmit the same quality video.
The H.265 codec standard retains some of the original technologies of the H.264 video codec, while improving some related technologies. The new technology uses advanced technology to improve the relationship between code stream, encoding quality, delay and algorithm complexity, and achieve optimal settings.
H.264 codec is used in the deployment and management of high-definition surveillance, a high-end surveillance equipment integrating image processing technology, network technology, and embedded design. It is often used in applications such as video conferencing and streaming media, and is usually mainly used in the broadcasting industry and front-end applications.
The H.265 algorithm is more complex and the compression efficiency is higher.
The difference between H.264 codec and H.265 codec:
H.264 video codec is a low-latency high-definition video image processing algorithm; standard H.264 video compression algorithm; H.264 normally supports 4 channels of 1080p30 simultaneous decoding and output.
H.265 video codec is an upgraded version of H.264. H.265 normally supports 16 channels of 1080p30 simultaneous decoding and output, and 4K HD video simultaneous decoding and output. With the same image quality, H.265 encoder occupies less bandwidth than H.264 encoder.
1. H.265 is a new encoding protocol, which is an upgraded version of H.264. .
2. With the same image quality and same bit rate, H.265 theoretically takes up 50% less storage space than H2.64.
3. H.265 video decoder occupies less storage.
4. H.264 can realize standard definition digital image transmission at a speed lower than 2Mbps, while H.265 HighProfile can realize 1080p full HD video transmission at a transmission bandwidth lower than 1.5Mbps.
5. In the era when 1080P is the pursuit of ultimate movie viewing, H.264 is the most ideal decoding method, and as 4K becomes a major industry trend, H.265 is its most ideal partner.
H265 encoding can support 4K 3 0 Hz resolution video input, and supports H.265 (HEVC) encoding/H.264 high-performance encoding. After HDMI video source is encoded and compressed, it can realize long-distance transmission/live broadcast of ultra-high-definition video over the Internet WAN or LAN through a wired network.
D300H265 decoding can decode multiple network streams and output SDI signal and HDMI signal video, support 4K resolution, 16 channels split screen on the wall.
HDMI and SDI dual interface output, support the same or different content output of HDMI and SDI.
H265 decoded image enhancement and error tolerance technology, for low bit rate encoded video, about 10% network packet loss video, etc. can be clear, distortion-free decoding output. The input terminal supports mainstream network video protocols such as RTMP/HLS/TS OVER UDP/RTP/RTSP/SRT, and also supports protocols such as SIP/VOCP.
