PROBLEM TO BE SOLVED: To provide a digital broadcast receiving set which disables a transport stream to be taken directly out of a front-end part (FE part) 1 by electrically programming the FE part 1 each time the FE part 1 is mounted on a back-end part (BE part). SOLUTION: The digital broadcast receiving set includes the FE part 1 which generates a transport stream from a received digital broadcast and the BE part 2 which generates a video signal and an audio signal from the transport stream; and a 1st interface (1st IF) 8 is arranged at the FE part 1 and a 2nd interface (2nd IF) 12 is arranged at the BE part 2, the FE part 1 and BE part 2 being enabled to contact and leave each other through the 1st and 2nd IFs 8 and 12. The FE part 1 is provided with an integrated circuit 7 which can program internal functions and the BE part 2 is provided with a memory 11 which stores program information of the integrated circuit 7; and the 1st and 2nd IFs 8 and 12 are provided with a program transmission terminal for transmitting the program information and a power supply terminal for supplying a source voltage.
