Abstract:
1. A method of reproducing at least first images and second images simultaneously, synchronizing the first images with the second images, the method comprising the processes of: reading first image data which is compressed data representing the first images and second image data which is compressed data representing the second images from a recording medium; storing the first image data read from the recording medium into a first memory device and storing the second image data read from the recording medium into a second memory device; and separately and simultaneously decoding the first image data stored in the first memory device and the second image data stored in the second memory device by using a first decoding device for decoding the first image data and a second decoding device for decoding the second image data, wherein, on the recording medium, each of the first image data and the second image data is divided into a plurality of data units each having an equal time length, each of the data units of the first image data and each of the data units of the second image data are alternately arranged on the recording medium, the data units are sequentially read from the recording medium in an order of an arrangement of the data units recorded on the recording medium, the process of storing the first image data and the process of storing the second image data are alternately carried out for each of the data units, and the process of decoding the first image data and the process of the second image data are carried out at a same decoding rate in a parallel manner.
