Abstract: 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.

Abstract translation: 公开了一种用于编码视频数据帧的视频编码器和方法。 视频编码器的编码器检查要编码的视频数据帧的总容量，并且通过使用从先前GOP提取的P帧的平均容量，根据检查的总容量来预测随后将被编码的P帧的数量。 根据缓冲器的可用容量，从P帧的预测数量计算由于缓冲器溢出而将被跳过的帧的数量。 根据预测的P帧数和GOP的帧数，将被跳过的帧的位置设置为不连续。 此外，在执行视频数据帧的编码的同时，选择当前编码的视频数据帧被布置在与要跳过的帧相同的位置，跳过视频数据帧的编码。 这里，从视频数据帧中，从成为其他视频数据帧的参考帧的1帧或从成为另一视频数据帧的参考帧的第一P帧除外的P帧确定跳过的帧。 因此，虽然防止了基本参考帧（即I和P帧）被跳过，但是也防止了连续的帧跳过，从而可以防止图像的整体质量下降。
