摘要： When inputting moving image data into a personal computer for display or for recording on a recording medium, there often occur cases where processing cannot catch up with the input, resulting in interruption of the processing. Also, when performing conversion from an input digital signal having an arbitrary number of samples to an output digital signal having an arbitrary number of samples, prior art methods entail the possibility that the memory capacity and the amount of computation may become enormous. In view of this, according to the present invention, if the image processing cannot catch up with the input, the data is re-input for processing by utilizing information concerning the recorded position, the recorded time, or the time at which playback is to be performed; this achieves the same effect as processing continuous moving image data without interruption.

摘要： The present invention includes methods and apparatus for attaining high speed coding and decoding. A first method decreases the number of memory access times by performing signal format conversion, orthogonal transform and continuous variable-length coding with predetermined small areas in a frame used as units. A second method omits orthogonal transform computation by using orthogonal transform coefficients to shorten the processing time. A third method uses additions and subtractions for orthogonal transform thereby decreasing the number of registers used and reducing the number of memory access times. The present invention further includes a decoding method for variable-length decoding wherein table size is not made larger because the number of table access times per code word is set to a maximum of 2, and plural code words are decoded by one table access operation to attain high-speed decoding.
