Abstract: 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 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.

Abstract: A cooling apparatus for use with an electronic system provides an uninterrupted operation capability. A pump supplies a cooling liquid to a liquid-cooled electronic system. The pump is controlled by a controller that also controls a three way valve for controlling the operation of a three-way valve for regulating the flow quantity of the cooling liquid flowing into a heat exchanger for cooling the cooling liquid. The cooling apparatus has a plurality of cooling control units. While one cooling control unit is in operation, the other is in the standby state. If one cooling control unit fails, the standby cooling control unit is automatically put in the operating state, thereby allowing servicing of the failing unit without interrupting the operation of the liquid-cooled electronic system and the cooling apparatus.
