Video encoder is also called video server, or DVS (Digital Video Server) for short. It is mainly used to encode and compress analog video signals and provide network transmission function. The difference with DVR products is that DVS focuses on the "video recording" function. ( )
举一反三
- The video analysis based on the front-end encoder is completed at the front end, which can not only reduce the pressure of network real-time transmission, but also reduce the pressure of back-end server's operation processing, and make the video content analysis more distributed and real-time. ( )
- The video analysis based on the front-end encoder is completed at the front end, which can not only reduce the pressure of network real-time transmission, but also reduce the pressure of back-end server's operation processing, and make the video content analysis more distributed and real-time. ( ) A: 正确 B: 错误
- In case of DVS failure, the redundant encoder will start and perform coding compression, and the video stream will be recorded in the "account" of the redundant encoder. ( )
- In order to enable the computer to process the video, the analog video signal of the video source must be converted into a meter.The digital video form required by the computer is stored on the disk. This process is called the video () process. A: Sampling process B: ,Quantification process C: ,Decoding process D: ,Digitization process
- The function of the video distributor is one channel of video input and multiple channels of video output, with the functions of impedance matching and signal amplification. ( )
