摘要： A computer-implemented method includes receiving a feedback message from a receiver of image data. The feedback message includes a reference frame identifier associated with a reference frame correctly received or decoded by the receiver. The method further includes determining a difference between the reference frame identifier and a current frame identifier. The current frame identifier is associated with a current frame to be encoded and the difference indicates a number of frames between the reference frame and the current frame. The method also includes encoding the current frame based at least in part on the difference.

摘要： A radar data processing method is provided. The method includes dividing to-be-compressed radar data into groups, determining encoding parameters of each group according to at least one radar data in each group, and encoding each radar data in each group according to the encoding parameters of each group, to obtain encoded radar data.
