Abstract
The MPEG video data stored in a video memory is successively written to a buffer in accordance with an address held in an address register . When I picture is detected from the data read from the buffer, the information is fed to an I picture interval holder . The I picture interval holder holds an address register value when the previous I picture is detected, subtracts the previous address register value from the present address register value when the present I picture is detected, and holds the value (interval between the previous I picture address and the present I picture address). A next I picture address calculator adds the interval obtained in the I picture interval holder to the present address value stored in the address register , subtracts a predetermined value from the calculated value, and predicts the next I picture address.
