    摘要： Disclosed is a video encoder and a method for coding a video data frame. The encoder of a video encoder checks overall capacity of video data frames to be encoded, and predicts the number of the P frames which are to be subsequently encoded according to the checked overall capacity by using mean capacity of P frames extracted from a previous GOP. The number of frames that will be skipped due to an overflow of a buffer is computed from the predicted number of the P frames according to available capacity of the buffer. The position of those frames that will be skipped is set not to be continuous according to the predicted number of the P frames and to the number of frames of the GOP. Furthermore, while coding of the video data frames is being performed, a video data frame chosen to be currently encoded is arranged in the same position as a frame to be skipped is arranged, coding of the video data frame is skipped. Herein, the skipped frames are determined, from among the video data frames, from 1 frames which become reference frames of other video data frames, or from P frames, except a first P frame, which becomes a reference frame of another video data frame. Accordingly, while essential reference frames (i.e., I and P frames) are being prevented from being skipped, consecutive frame skips are also prevented from occurring, and therefore the overall quality of pictures can be prevented from being degraded.
