A data broadcasting system for the low-cost delivery of character-heavy data such as newspapers and magazines. Newspaper or other data are transmitted from a newspaper publisher or service to an artificial satellite via a broadcasting center to be relayed to a subscriber. The subscriber receives the data by means of a receiver via an outdoor apparatus. The received data are sent to a recorder to be recorded on a recording medium such as a compact magneto-optical disc for later display.

1. Field of the Invention
The present invention relates to a data broadcasting system suitable for electronically distributing, via an artificial satellite, such information mainly composed of text (or characters) as newspapers, magazines, and books that are conventionally distributed directly to readers or sold in stores on a daily or otherwise regular basis.
2. Description of the Related Art
FIG. 1 is a diagram illustrating the data broadcasting system practiced as one preferred embodiment of the present invention;
FIG. 2 is a block diagram illustrating a construction of a broadcasting center of the embodiment of FIG. 1;
FIG. 3 is a diagram illustrating spectra of data to be entered in an FM modulator of FIG. 2;
This invention will be described in further detail by way of example with reference to the accompanying drawings.
Now, referring to FIG. 1, there is shown the data broadcasting system practiced as one preferred embodiment of the present invention. A newspaper publisher as an information sending party has a mainframe 1. The mainframe 1 holds a newspaper page database. The newspaper page database contains article information to be printed and layout information. The data held in this database are transmitted as required to an editing workstation 2 to be edited.
To be more specific, the article data are edited by the editing workstation 2 on an article type basis into a form in which the data can be most easily retrieved by the receiving party. For example, this editing facility creates a screen for retrieval in which a page is reduced with its layout unchanged and only headlines displayed. Further, the retrieval screen (headlines) listing is related to the articles whose headlines are displayed so that selecting one of the headline displays the corresponding article. The data thus edited into a form in which the receiving party can retrieve the data easily are transmitted to a broadcasting center 3 via a ground data circuit.
