DIGITAL BROADCAST RECEIVING DEVICE AND SOFTWARE DOWNLOAD METHOD

摘要

In a digital broadcast receiving device and a software download method, regardless of the operation of a main power switch, a power control unit supplies standby power to perform download and software update of a software storage unit when unperformed download scheduled time information is stored in an SDL information storage unit. After the completion of the software update, the power control unit stops the standby power supply and stops the supply of power to the digital broadcast receiving device similarly to when the main power is turned off by the operation of the main power switch. Further, when the supply of external power is stopped, the standby power is supplied by using a built-in charging battery.
