At present, there are still many radio and television fields that use traditional cameras instead of network cameras. Traditional videos will be very large without streaming media. At this time, high-definition encoders can be used to solve this problem, and compression can be reduced. To be suitable for network transmission, IP address can be set at the same time, and it has a streaming function. In order to better play the role of high-definition and standard-definition encoders, you should also pay attention to the following aspects when choosing.

高标清编码器选择需注意哪些事项

1. Pay attention to whether it has SDI/HDMI input interface


Since this is a high-definition interface, it is also a serial digital interface used for video transmission. It is based on the Smpte serial link standard, so you can use this to judge the quality of the high-definition encoder. This interface of the high-definition encoder uses the original video data for transmission, and without compression, it can ensure lossless image quality and truly present the video content, and because the video signal is not compressed, it will not cause image delay.


2. Pay attention to see if it has expanded 4G network function and wifi function


Because the device needs a Unicom network to operate, 4G and WiFi are very basic functions. Therefore, when choosing a high-definition encoder, you should look at whether it has such a function. This is one of the high-quality new-generation wireless broadband communication standards. It has the characteristics of high speed, low latency, and internationalization. It would be better if the HD and SD encoders can also be equipped with dual-band wifi modules, which can realize various forms of wireless network transmission.


3. Pay attention to the H.265 encoding function technology


At present, most webcasting platforms use this technology, because the best-selling HD/SD encoder in the industry is a video compression standard, and it has been improved a lot in terms of technology, making it better in video quality and transmission. Speed and other aspects have reached a very high standard. Therefore, this is also one of the reference standards for selecting high-definition and standard-definition encoders, which can optimize various functions and settings to a large extent.


The above are several aspects included in the selection of high-definition encoders. In addition, it should also be determined whether it can support multi-protocol functions. The current high-quality and durable HD and SD encoder output must support the RTMP/RTSP protocol, because it is the current standard protocol for encoder output, and Windows browsers basically support this protocol, so this is also a very basic requirement.
