2. Description of the Related Art In the United States, several electronic newspapers using computer networks have already been published. Electronic newspapers use Videotex (text and graphics information system) to deliver articles with the same content as the morning edition of the day directly to a personal computer at home or office. The electronic newspaper system searches the news on the PC display and retrieves the article you want to read from the morning edition of the day. You can also search past articles. All electronic newspapers commonly publish all the newspaper articles on the day.

[0003]

Since electronic books and electronic newspapers carry a large amount of various information, a large-capacity storage device is required for the receiving / displaying device to receive and store all the information. . There is a limit to the storage capacity of a handy portable reception / display device that receives information via communication means such as mobile communication or broadcast radio waves and stores it in a memory. In order to popularize electronic book and electronic newspaper systems, how to efficiently store effective information in the limited-capacity memory of the receiving / displaying device is an issue.

The present invention aims to solve these problems.

[0005]

In order to achieve the above object, the present invention has the following constitution.

That is, in a system such as an electronic book or electronic newspaper that provides information by adding an identification code for each information to information such as a book or newspaper, it is added for each information together with the information about the book or newspaper. The receiving means for receiving the identification code of the information, the registration means for pre-registering the identification code of the information desired by the user, the identification code of the information received by the receiving means and the identification code of the information registered by the registration means A large amount of received information is provided by including an extracting unit that extracts only matching information from the received information and a storing unit that divides the information extracted by the extracting unit for each identification code and stores the information in a memory. The receiving / displaying device is characterized in that only information desired by the user is selectively stored in a memory and displayed.

[0007]

The receiving means receives the identification code of the information added to each information together with the information of the book or newspaper. The registration means previously registers the identification code of the information that the user wants to see. The extraction means extracts from the received information only information in which the identification code of the information received by the receiving means and the identification code of the information registered by the registration means match. The storage unit divides the information extracted by the extraction unit for each identification code and stores it in the memory.
