- 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. ( )
- 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. ( )
- Which of the following accurately describes the meaning of redundant cooling？（） A: The source of cooling to a RAID system B: The cooling system in a redundant power supply C: A cooling system that can be installed in case of failure D: A second cooling system in case of a failure
- The premise of data compression is that there is more or less redundant information in the data, and for multimedia information such as video and audio, humans can use their own perceived redundancy (distortion) characteristics to achieve a higher compression ratio. ( )
- The encoder of the block transform coding system performs four operations: subimage decomposition, transformation, ______ and coding.
