INFORMATION PROCESSING DEVICE, BROADCAST RECEPTION DEVICE, AND SOFTWARE-DATA UPDATE METHOD

摘要

The present invention reduces the amount of time from when a device such as a digital broadcast receiver is powered on until video corresponding to a digital broadcast signal received by the device can be displayed. In order to do so: the processing load on the main control unit (101) while software data used in a startup process in the broadcast reception device are being transferred and decompressed is measured; on the basis of information about the measured processing load on the main control unit (101) over time, a compression process using a compression type and compression ratio that minimize the total time taken to transfer and decompress the software data is determined; and the software data are compressed using the determined compression process and stored in an auxiliary storage unit (107).
