摘要

The invention provides a memory address generation device (507) capable of generating a plurality of addresses used in a memory, which enables signal processing of a plurality of non-synchronous video signals using only one memory. One of a plurality of reference addresses (508) may alternatively be selected (509). One of a plurality of offset values (503) may alternatively be selected (504).
