In a method and apparatus for decompressing a digital video signal representative of an input sequence of digital video frames, a digital video signal is provided to a video decompressor having a target frame decompression rate which is initially set at the maximum possible frame rate. The output of the video decompressor is monitored to determine whether the video decompressor is timely generating the output sequence of digital video frames. If the video decompressor is not timely generating the output sequence of digital video frames, then the video decompressor output is adjusted by omitting from the output sequence at least one frame from the input sequence. A frames missed value is generated in response to each group of one or more omitted frames, and deviations in the frames missed value are monitored. The target decompression rate of the video decompressor is selectively adjusted downward in response to deviations in the frames missed value. |
