Proper data is selected from a plurality of data which are multiplexed and transmitted to download the proper data. The maker and model of a receiver and the version of a control program are stored in a load section as a maker ID, a model ID, and a version ID. The section number and the total number of sections are also stored. It is checked whether the maker ID and the model ID coincide with those stored in the ROM of the receiver to check whether the version number is newer than that of the control program of the receiver. Therefore, it can be checked whether the program should be downloaded. With reference to the list of section numbers which have been downloaded, it can be found whether a program divided into a plurality of sections to be transmitted is completely downloaded. With reference to the list of section numbers and the total number of sections, the progress state of downloading can be known.
