PURPOSE:To obtain a device which receives and displays information of plural programs simultaneously and displays information of a desired program out of them separately, by providing two systems for receiving of character information and etc. superposed in the vertical blanking interval of a television signal. CONSTITUTION:Plural means which select only multiplexed information signals of plural programs designated preliminarily by a program selecting circuit 12 and store and display them and a means which reads out the pattern data signal of a desired program and dispalys it are provided. For example, pattern data are stored successively in main memory 2 11 and are displayed on a CRT14 independently of designation of desired receiving programs in the program selecting circuit 12. Meanwhile, desired information found by pictures of multiplexed information or the CRT14 is displayed on a CRT13 through a main memory 1 10, and thus, specific desired information is selected while monitoring all of multiplexed information as the whole. |
