Abstract
A system for the so-called 'pay-per-program' is provided for viewing individual program on pay basis without signing a comprehensive contract. In response to a request for viewing a pay program executed via public telephone line from an applicant for viewing, a charging center sends a viewing permit code for viewing a pay program to a data communication device and collects a fee for the pay program. Upon receipt of the viewing permit code, a receiving device offers the pay program according to the viewing permit code. The broadcasting program is scrambled by three modes of fixed, selective and change. The request for viewing is executed in three modes by specifying time, program number and temporary number. As the viewing permit code, one of three modes is adopted: decode data, non-opened program number or decode data number.
