Abstract
A program guide information producing apparatus outputs self-produced program guide information and other broadcaster's program guide information. In the program guide information producing apparatus, a common program guide information producing section generates self-produced common program guide information. Furthermore, a program guide information output section unites the self-produced common program guide information with other broadcaster's common program guide information received from a program guide information collecting/transmitting apparatus and outputs the united common program guide information. Thus, the self-produced common program guide information is surely output even when the program guide information collecting/transmitting apparatus or the like is in trouble.
