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. ( )
举一反三
- 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. ( ) A: 正确 B: 错误
- When multiple people operate a machine tool, ( ) A: two people can operate the machine at the same time B: only one person can operate at the same time C: only one person can operate at the same time, and other students can leave the machine to rest D: All of the above are correct
- In order to obtain high compression ratio and high-quality images that can be randomly stored under the condition of efficient encoding and compression, MPEG defines three frame types, namely: ( ) A: I-frame B: P-frame C: B-frame D: T-frame
- Answer: First, this group lacks structure because it is made up of _______ who operate independently of each other. Second, _______.
- 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. ( )
