Abstract

A cable TV computer fees collection system is provided with network service, primary controlling computer, adjacent frequency modulator, adjacent frequency mixer, adjacent frequency amplifier, signal controller with slave control computer and user distributor with computer. The primary controlling computer sends out a digital controlling instruction to adjacent frequency modulator, mixer and amplifier according to user payment information provided by network service. After having been amplified to 110dB, the instruction is passed through the cable TV network and received by signal controller with save control computer, then frequency-changed and amplified, demodulated so as to control the user distributor with computer to cut off or on TV signal. The system replaces that person go to the doorstep to ask for payment of watching TV program, and makes automanagement of cable TV fees collection is realized.

Description

Computerized charge system for cable TV programme
The present invention relates to cable television charging system, particularly Computerized charge system for cable TV programme.
At present, it is the means professional TV programme of charge that started broadcasting with the digital compression signal scrambling technique that China Chinese Central Television (CCTV) utilizes No. 5 satellite repeaters of culminant star, and the mode that various places cable TV station then adopts two level scramblings is to each user professional TV programme of charge that starts broadcasting.The cable TV station that carries out this business removes needs to drop into the video server that huge fund is purchased import, outside the digital device such as ATM switch and Node Controller, each user also need purchase one and be worth about about 800 yuans decoder, owing to be subjected to the restriction of program source, the attraction of charging TV program is little, general program also can receive by television station, thereby, most of users are reluctant to spend nearly thousand yuan investment again and watch charging TV program, therefore, its exhausted most investment will be born by cable TV station oneself, in order to recoup capital outlay, cable TV station just needs to improve license fee, this also is that the user is burdensome, in view of reason technical and economically, the current domestic overwhelming majority's cable TV station all adopts manual toll collection, and the manual toll collection workload is big, leak is many, even causes the loss of a large amount of expense moneys.
The purpose of this invention is to provide a kind of Computerized charge system for cable TV programme, to solve many weak points that present manual toll collection exists.
