Suitable for broadcast-level HD video encoder IP transmission technology

Broadcast video encoders are very suitable for satellite, terrestrial broadcasting, cable networks, IPTV applications, and various other content point-to-point/point-to-multipoint applications. Low latency, smooth audio and video, and high-definition picture quality are the criteria for broadcast-level selection. The video encoder takes the captured video to the encoder to pull the stream and then to playback. Among them, the encoding ability will greatly affect the video definition and the consumption of bandwidth resources. Therefore, it is very important to choose a cost-effective encoder. The following editor will briefly popularize science: Broadcast-grade high-quality technology Thousand Vision's new 4K video encoder with NDI technology can realize broadcast-level ultra-high-definition video IP live broadcast. The traditional SDI/HDMI video signal can be reliably transmitted to IP-based on-site production equipment, such as various software and hardware production equipment, video mixers, image systems, etc., without complicated wiring, which helps you save complicated equipment Cost and maintenance cost. The biggest advantage of NDI is that the NDI standard is open and can be used with confidence. Many radio and television equipment manufacturers now support NDI and are compatible with traditional radio and television equipment. The entire system integration architecture is very simplified and has strong compatibility. At the same time, it supports 4:2:2 sampling specifications of 10bit color depth 4K60p ultra-high-definition color signal, which can reduce bandwidth by up to 50% under the same image quality, or significantly improve image quality under the same bit rate, effectively reducing network bandwidth , Reduce content production costs. Suitable for broadcast-level HD video encoder IP transmission technology End-to-end ultra-low latency From the video content collection of the camera to the display on the user side, there are many links, which can be roughly divided into camera collection→video encoding→image processing→streaming media format conversion and transmission→video decoding→display, any of which changes the video content and streaming transmission process Will increase the delay, so choose a low-delay encoder in the video encoding link, which can effectively reduce the entire end-to-end delay. N20 NDI 4K codec supports FULL NDI protocol, the end-to-end delay in the LAN is only 1-3 frames (about tens of milliseconds, while the traditional RTSP transmission end-to-end takes about 300 milliseconds), and supports 4K P60 ultra-high-definition resolution Rate, support Tally display and PoE power supply, transmission needs the support of gigabit network environment. Suitable for broadcast-level HD video encoder IP transmission technology Multiple streaming media protocols The most common encoders on the market support streaming media protocols such as TS-UDP, RTP, RTSP, and RTMP. In addition to common protocols, Thousand Vision also supports SRT, NDI, GB/28181, Onvif and other protocols. SRT transmission technology has the advantages of "low latency and anti-network jitter". The end-to-end transmission of the Internet can be controlled within 1 second, and the picture still does not flicker or freeze under the condition of 20% network packet loss. All the codecs of Qianshi Electronics have supported the SRT transmission protocol. Qianshi Electronics' full series of codecs are broadcast-level standard transmission equipment, which is widely used in program production, sports, news gathering and other live broadcast activities content distribution. Successful cases include the Hunan Radio Project, the 2019 Military Games, the outside video transmission and recording of the Jiaolong manned submarine, the Houguan Lake Half Marathon, etc., and they have had a very good reputation in the domestic live broadcast industry.
