RECEPTION SYSTEM, BATTERY CHARGING DEVICE, PORTABLE INFORMATION TERMINAL, AND TRANSMISSION AND RECEPTION SYSTEM |
摘要 |
Data can be received by a battery charging device while a portable information terminal powered by a secondary battery is connected to the battery charging device to charge the secondary battery. For data reception, the battery charging device has a tuner as a data reception circuit. While the portable information terminal is mounted in the battery charging device, the secondary battery is charged by the battery charging device, and the tuner receives a television wave containing a data broadcast. Data multiplexed in a video signal outputted from the tuner is decoded by a data decoding circuit, and stored into a data storage device of the portable information terminal. The data stored in the data storage device can be reproduced on a liquid crystal display unit of the portable information terminal when it is detached from the battery charging device. |
