If the viewing condition is free, the received broadcast program is decoded by the multifunction device 75 (s
83) After that, the image quality is degraded by the transconductor 76 and output to the monitor 4. When the viewing condition is paid and only viewing is performed, billing information (low charge) is transmitted to the broadcasting device 1 via the modem 71 (s85), and the received broadcast program is decoded by the decoding device 77 as it is. Output to monitor 4. When the viewing conditions are stored (downloaded) for a fee, the billing information (high fee) is transmitted to the broadcasting device 1 via the modem 71 (s86), and the received broadcast program is stored on the hard disk 78, and appropriately. , Decoded by the decoding device 77 and output to the monitor 4.

The contents of the present invention described above are the same but different programs include, for example, a program for which the viewing fee is free but a large number of advertisements are inserted, and a program for which the viewing is paid but the advertisement is completely inserted. In addition to the no-show program, a program in which an advertisement is inserted can be handled as a different program depending on the degree of insertion. The programs having different quality are, specifically, a video quality program which is free of viewing fee but is compressed and transmitted at 3 Mbps, and a video quality program which is paid and charged at 6 Mbps but is compressed and transmitted at 6 Mbps. And can be treated as many more different programs depending on the degree of quality as well.

In the above-described embodiment, an example has been described in which the charging information is stored when the viewing method is selected. However, the charging information can be integrated as timekeeping information. Can be configured to be changeable. Further, although the description has been given of the example in which the charging information storage unit is provided on the broadcasting device side, it is needless to say that the charging information storage unit can be provided on the viewing device side.

[0061]

As described above, according to the program broadcasting method of the present invention, the same contents are not selected according to the selected viewing method, but the alternative contents to select whether or not to view a specific program. It gives you the opportunity to watch different programs,
It is possible to provide a program that meets various needs of the viewer. In particular, since the viewing conditions such as the billing settings are changed according to the viewing method of the viewer, even if the same viewing is performed, for example, the user may view a program with an advertisement with a low viewing fee or a program with a high viewing fee. It is possible to provide a program that can be selected according to the needs of the viewer such as whether to view a program without advertisement. It enables a broadcasting business that has never existed before.
