Abstract: This application provides an image encoding and decoding method and apparatus. The image encoding method in this application includes: obtaining a to-be-processed first image feature; performing non-linear transformation processing on the first image feature to obtain a processed image feature, where the non-linear transformation processing sequentially includes a first non-linear operation, convolution processing, and an element-wise multiplication operation; and performing encoding based on the processed image feature to obtain a bitstream. This application can avoid limitation on a convolutional parameter, to implement efficient non-linear transformation processing in an encoding/decoding network, and further improve rate-distortion performance of an image/video compression algorithm.

Abstract: A data transmission method and a device is provided. The method includes: receiving, by a first terminal device on a broadcast channel, a broadcast message sent by a second terminal device; sending, by the first terminal device, a first acknowledgment message to the second terminal device on the broadcast channel, where the first acknowledgment message is a response message indicating that the first terminal device successfully receives the broadcast message; obtaining, by the first terminal device, first data carried in the broadcast message when determining that the broadcast message carries the first data; and reporting, by the first terminal device, the first data to a corresponding application server. According to the method and the device in this disclosure, signaling overheads of a device can be reduced.

Abstract: A file processing method and a storage device are disclosed. In the method, a storage device receives T files that are to be stored in the RAID, and determines a sequence number of a check block in a stripe of the RAID. The storage device repeatedly obtains a data block of the Kth file in the T files as the Kth data block in the stripe, where a value of K progressively increases from 1 to T, and the value of K is not equal to the sequence number of the check block in the stripe. After computing the check block according to data blocks, the storage device writes, into the T disks, the data blocks and the obtained check block in the stripe. By using the foregoing method, one file can be written into one disk of the RAID while ensuring security of file storage.

Abstract translation: 公开了文件处理方法和存储装置。 在该方法中，存储装置接收要存储在RAID中的T文件，并且确定RAID的条带中的检查块的序列号。 存储装置重复获得T文件中的第K个文件的数据块作为条带中的第K个数据块，其中K的值从1逐渐增加到T，并且K的值不等于 条纹中的检查块。 在根据数据块计算检查块之后，存储设备将数据块和获得的条带中的检查块写入到T盘中。 通过使用上述方法，可以将一个文件写入RAID的一个磁盘，同时确保文件存储的安全性。
