Abstract

PURPOSE:To secure the instantaneous projection of at least one character broadcast program without any queuing time, by providing the nonvolatile memory and the program designation switching circuit. CONSTITUTION:In nonvolatile memory 24, the program designating code for one specified character broadcast program is memorized in the address of the corresponding channel with every TV broadcast channel. And with operation of channel selector 17, FF16 is set and the output turns to 1. Thus the AND gate of switch circuit 25 is opened, and then the designating code of memory 24 is supplied to comparator 11. Then transfer gate 8 is opened by the coincidence signal of circuit 11, and the designating code of memory 24 is memorized in main memory 15. And the output of FF16 is 1 in circuit 3, and the selected program is projected immediately under these conditions. Here if the selection is done by character broadcast program selector 12, FF16 is reset with the output turned to 0. And the information of memory 15 is projected instantaneously on the screen. In such way, at least one character broadcast can be viewed immediately.
