DATA REDISTRIBUTION DEVICE AND DATA DISPLAY DEVICE

PROBLEM TO BE SOLVED: To provide a data redistribution device capable of narrowing down broadcast data which should be redistributed so as not to disturb the television viewing of a user, even when it becomes a situation that transmission bands of a communication line for redistributing digital broadcast data from a redistribution device to a display device run short. SOLUTION: The redistribution device is characterized by separating the digital broadcast data received by the redistribution device into data 1 which is used for data broadcast, and data 2 other than the data 1; adding program configuration identification information 1 to the data 1; adding program identification information 2 of the data 2 to the data 2; and preferentially transmitting the data 2 to the display device which displays broadcast data than the data 1.
