Abstract:
An information service system linked to a broadcasting system is provided which comprises at least one content provider, a broadcasting center and user sides. The content provider multicasts a content over the Internet to users. The broadcasting center broadcasts a program signal which contains an index for identifying the content after the content provider multicasts it. The user's facilities comprise a storage device for storing the content multicast from the content provider, an extraction device for extracting the index from the broadcast signal, an indication device, in response to the extraction of the index, for indicating that the index corresponding to the content previously stored in the storage device, has been received. When a user pushes a predetermined key of a PC terminal while the indication device indicates the reception of the index, a content corresponding to the index is read from the storage device and displayed on the PS screen.
