摘要： A slice decoder control circuit sequentially supplies the parameter of the picture layer and the write pointer of a first slice to a first slice decoder, the parameter of the picture layer and the write pointer of a second slice to a second slice decoder, and the parameter of the picture layer and the write pointer of a third slice to a third slice decoder, and causes the slice decoders to decode the respective parameters and write pointers. On the basis of the input of signals indicating the completion of decoding processing inputted from the slice decoders, the slice decoder control circuit supplies the write pointer of a fourth slice to the second decoder and causes the second slice decoder to decode the write pointer at timing A, and supplies the write pointer of a fifth slice to the third decoder and causes the third slice decoder to decode the write pointer at timing B. Subsequently, the similar processing is repeated until the last slice is decoded. The operations of a plurality of slice decoders are thus controlled.
