Abstract
Prediction of and recovery from display buffer underflow are described. A first time delay for displaying a first group of one or more frames of a video picture stream located in an output frame buffer is calculated. A second time delay for displaying a second group of one or more frames in the picture stream is calculated. The second group directly follows the first group in the output buffer and is currently decoded by a decoder, but not yet deposited into the output frame buffer. A third time delay for decoding a third group of one or more frames in the picture stream is calculated. The third group directly follows the second group and is not yet decoded by the decoder. The decoder switches to or remains in a fast decoding mode if the sum of the first and second time delays is less than the third time delay.
