Abstract: An access unit to be decoded is selected from data stored in a coded picture buffer (CPB) (56). If the access unit is an IDR (Instantaneous Decoder Refresh) picture, it is checked whether a decoded picture buffer (DPB) (60) has a free area enough to store the access unit. If the DPB (60) has a sufficient free area, a decoder (58) stores the decoding result in the DPB (60), and selects the next access unit from the CPB (56). If the DPB (60) does not have a sufficient free area and the earliest stored picture has already been displayed, the buffer area of the displayed picture is deallocated. If the earliest stored picture has not been displayed, a warning is displayed to the user. All memory areas in the DPB (60) except for the area of a currently displayed picture are deallocated to wait for an IDR picture.

Abstract: A recording apparatus includes a write unit to write information data read from a memory by irradiating a disk medium with a beam in accordance with the information data, and a control unit to, upon the amount of information data stored in the memory reaching a threshold, instruct the write unit to start writing of the information data. In response to the write instruction, the write unit reads the information data stored in the memory and writes the read information data onto the disk medium while it is rotating. Upon the amount of information data in the memory decreasing to a predetermined value, the write unit stops reading and writing of the information data from the memory and onto the disk medium. The control unit sets a value of the threshold in accordance with the number of times the write unit has performed writing of the information data.
