A video codec is a program or device that compresses or decompresses digital video. In real life, video encoders play a very important role. Let's talk about the role of video encoder.
Video encoder function
The role of the video encoder in the monitoring system is: the audio and video signals collected by the front camera, pickup, etc. are compressed and encoded, transmitted to the monitoring center of the back end through the network, and decoded by the corresponding decoding software or hardware running on the PC. The device performs decoding and playback.
For example, through the camera placed in the conference room, the image and sound inside the conference room are transmitted to the connected video and audio encoder, and the collected signal (via the internal network) is transmitted to the background management platform through the encoding of the encoder. In the DSS-R recording server. The live broadcast module of the server distributes the signals received from the audio and video encoders to the network, and each computer in the office that accesses the internal network receives the real-time content through the proprietary client, and simultaneously records the built-in recording module of the server. The decoded signal content is saved and recorded (there are hard disks available for storage in the server).
Video encoder application
Video encoders are widely used in home satellite broadcasting services, terrestrial digital television broadcasting, electronic cinema, electronic news gathering systems, personal communications, multimedia mail, web databases, home television theaters, remote monitoring and television on demand systems.
Summary: This article briefly describes the role of video encoders in surveillance systems. If you want to know more about the role of video encoders, please continue to pay attention to the hot security investment network.
