Abstract
An object is to make efficient pre-reading possible even in receivers having little memory for receiving. A CPU acquires data size in each module by referring module control information for a received DII, (step S ). The data sizes of the modules are compared with the remaining memory in a RAM (step S ), and modules smaller than the remaining memory are pre-read into the RAM (step S ). When a pre-read flag is not on, then no pre-reading is done even when a module is smaller than the remaining memory. Thus data that are updated from time to time can be excluded from being subject to pre-reading.
