- Since the video encoding process requires unidirectional or bidirectional reference prediction, the order of image compression, transmission, and display is not consistent. ( ) A: 正确 B: 错误
- MJPEG encoding compression technology is a dynamic image compression method based on the development of static image compression technology, which can compress continuous video streams to produce an image sequence. Its advantages are: ( ) A: Relatively simple to implement B: Encoding delay is small C: The picture can be spliced arbitrarily (the picture does not matter directly) D: Can flexibly adjust the compression frame rate and resolution
- Evaluation criteria of video image coding and compression technology ( ) A: Bit rate B: Reconstructed image quality C: Encoding / decoding delay D: The capability of error repair
- According to the consistency between the original image and the reconstructed image, the encoding techniques are divided into ______ compression and ______ compression.
- 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
