Abstract
Abstract 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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
138 words
A data broadcasting method for transmitting predetermined data via a broadcasting channel, comprising the steps of: scrambling retrieval page and article page data including one of a newspaper, a magazine, and a book using a scramble key to obtain scrambled data; encrypting data related to the scramble key, common information, a receiver ID, and subscription terms to obtain encrypted related data; inserting the scrambled data and the encrypted related data into a predetermined artificial satellite channel; transmitting the predetermined channel including the scrambled data and encrypted related data via an artificial satellite; receiving the transmitted scrambled data and encrypted related data from said artificial satellite; decrypting the received encrypted related data to obtain decrypted related data; and unscrambling the received scrambled data using the received scrambler key to obtain unscrambled data to reproduce said newspaper, magazine, and book.
