This invention provides a method to control the buffering of encoded video data organized as frames or fields. This method involves determining the picture number of each incoming decoded frame, determining the expected presentation number at any time and marking any buffer as ready when its picture number is on or after the presentation number.

1. An apparatus processing video data frames operating at a decoded data rate, and a display data rate, comprising:a first, second, and third buffers; the first buffer storing a first video frame, the first video frame being read from the first buffer at the display data rate; the second buffer storing a second video frame, the second video written to the second buffer at the decoded data rate; the decoded data rate being unequal to the display data rate; and the third buffer storing the video frame decoded immediately following the second video frame.
