Abstract
The video sending method includes: acquiring a video stream to be transmitted; generating consecutive frame groups from the video stream, wherein setting a first frame in the current frame group to be a long-term reference frame that uses a first frame in a previous frame group as a reference during generation of at least one of the current frame group, wherein the long-term reference frame is a predictive coded frame configured to transmit a difference and a motion vector obtained by performing a comparison against the first frame in the previous frame group, the current frame group is a frame group other than the first frame group; and sending the frame groups to a receiving terminal. The video receiving method comprises: receiving the frame groups sent by a sending terminal; and restoring the frame groups to obtain the transmitted video stream.
