- In IPC's independent chip+CPU architecture, the coding and compression work is done on the same chip as the system master. ( )
- From the external situation, IPC is integrated into video acquisition, image processing, video and audio coding and compression, network transmission, control, alarm and other functional modules on a circuit board to achieve video coding and uploading. ( ) A: 正确 B: 错误
- The difference between hard compression and soft compression in DVR is "who completed the encoding compression?" If it is done by the hardware chip on the board, it is called hard compression. If it is handed over to the CPU to complete, it is called soft compression. ( )
- 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. ( )
- The standards for measuring the advantages and disadvantages of coding and compression algorithms are ( ) A: Definition of image B: Real time C: Mosaic effect D: Smoothness, etc.
