Abstract: A frame dropping method for a video frame and a video sending apparatus are used to perform frame dropping processing on video frames in order to reduce a quantity of dropped frames, enhance video playing smoothness, and improve user experience. A specific solution includes obtaining a video frame sequence of a to-be-sent video, establishing a reference relationship between video frames in the video frame sequence according to a preset criterion, and detecting a data occupation length of buffered video frames in a video sending buffer during a process of sending the video frame sequence, dropping a current to-be-buffered video frame when the data occupation length is greater than a preset threshold, and dropping all video frames in the video frame sequence that reference the current to-be-buffered video frame according to the reference relationship.

Abstract: A method for creating a configuration knowledge base, includes: determining a hierarchical structure between a plurality of modules in a product family based on the plurality of modules; determining a knowledge package of each module based on the hierarchical structure; and releasing the knowledge package of each module in the product family to a configuration knowledge base, to obtain a configuration knowledge base of the product family. The hierarchical structure indicates a hierarchical relationship between a parent module and a child module in the plurality of modules. Each parent module includes one or more child modules. A knowledge package of the parent module includes an input interface algorithm of the child module associated with the parent module.
