摘要:
A billing system for use in a chargeable program broadcasting is capable of reliably billing a subscriber for program reception while preventing unauthorized reception thereof. A receiving terminal includes a primary terminal 100 and a secondary terminal 150. The primary terminal 100 receives a compressed video signal and confirms by an error checker 113 thereof whether there is a transmission error and bills, by means of a billing device 114 thereof, the receiving subscriber on the basis of an error information and a program information, etc., separated from the video signal by a separation circuit 112. The compressed video data is time-axis multiplexed with a terminal identifying code and a key signal and transmitted to the secondary terminal 150. In the secondary terminal 150, a bill for the subscriber is confirmed by the terminal identifying code and the compressed data is decoded by a decoder circuit 166 thereof.
