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. ( )
举一反三
- Multimedia means that computer information can be represented through audio, video, and animation in addition to traditional media
- The higher compression ratio gives a ______thermal efficiency
- Because MPEG-4 encodes each object independently, it can achieve a high compression ratio, and at the same time, it also provides the possibility to operate the content on the receiving end as needed, adapting to the needs of "human-computer interaction" in multimedia applications. ( )
- 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 displacement ductility of compression member will decrease with the increase of axial compression ratio.
