Abstract: A video processing method is provided. A target video frame is obtained from a video. A target data block is determined from the target video frame. Data block indicator information of the target data block is determined based on a scene complexity of the target data block. The target data block is divided into a plurality of subdata blocks. Subblock indicator information of the subdata blocks are determined based on scene complexities of the subdata blocks. An encoding mode for the target data block is determined according to the data block indicator information and the subblock indicator information. The target data block is encoded according to the determined encoding mode.

Abstract: A radio frequency transmitter includes N transmit channels, where each transmit channel includes one nonlinear module, a primary correction circuit, coupled to each of N nonlinear modules that correspond to the N transmit channels, and configured to provide a primary correction signal for the N nonlinear modules, and N secondary correction circuits, where the N secondary correction circuits are coupled to the N nonlinear modules respectively, and each secondary correction circuit is configured to provide a secondary correction signal for a nonlinear module coupled to the secondary correction circuit.
