This application provides a video encoding/decoding method, a corresponding video encoding/decoding apparatus. The video encoding method includes: obtaining a to-be-encoded video; encoding the to-be-encoded video to obtain a first bitstream and a second bitstream before outputting the first and second bitstreams. The first bitstream is obtained by performing frame skipping and encoding on the to-be-encoded video, and the second bitstream is obtained by encoding video frames in a second frame sequence by using video frames in a first frame sequence as key frames. The first frame sequence includes video frames obtained by downsampling video frames in the to-be-encoded video that are encoded into the first bitstream, and the second frame sequence includes video frames obtained by downsampling video frames in the to-be-encoded video that are not encoded into the first bitstream. The technical solutions provided in this application help improve video image prediction accuracy.

Frame skipping techniques in video encoding and decoding method

The apparatus includes a first transistor having a gate/base terminal to receive a first drive control signal used for controlling a driver stage of the transceiver and a drain/collector terminal coupled to a control terminal of a switch of the transceiver. The first transistor is switched on when the first drive control signal is at a first level that enables the driver stage to amplify a first RF signal. When the first transistor is switched on, the drain/collector terminal of the first transistor outputs to a control terminal of the switch a switch control signal at a second level that enables the switch to provide a portion of the RF signal reflected by the antenna to the load.
