CONSTITUTION:Of the data stored in a program RAM 5, for example, a stock quotation program is displayed on the screen of a TV receiver in accordance with a prescribed operation through a remote controller 15, etc. In addition, when, for example, a specific name is designated, a control section 6 takes out the price, etc., of the specific name and stores and accumulates the fetched data in a data memory 19 for selection. Therefore, accumulated prices of the specific name can be displayed collectively on the TV screen based on the necessary data stored in the data memory 19. Moreover, since, for example, the price fluctuation of the specific name can be calculated during the waiting time or vacant time, information indicating the tendency of price fluctuation can be obtained. |
