BUFFERING OF VIDEO STREAM DATA

摘要

Buffering of a video stream containing intra frames (I-frames) and inter frames (P-frames, B-frames) is disclosed. A buffer memory is segmented in two parts, a contiguous part for buffering of contiguous frames of the video stream (I-, P- and B-frames), and an intra part for the buffering of intra frames of the video stream. A decoding of the video stream may under normal conditions be done on data read from the contiguous part of the buffer, whereas the decoding of the video stream in a buffer-underrun situation may be done on data read from the intra buffer.
