Highstar cable TV plus descrambling CA and SMS

In the process of cable TV charging and management, most of the cable TV network companies charge the viewing and maintenance fees to the analog TV users by the company's toll collectors – the fees are difficult, the cost is high, and the benefits are low. In response to this situation, our company put forward an effective new idea of ​​cable TV charging management and business development, and developed a new generation of cable TV plus descrambling user control (CA) and management (SMS) system. The system installs a cable TV scrambling device and computer management system in the original cable TV front-end computer room, and installs a descrambler set-top box on the user's TV end to effectively manage and control the cable TV users in the network. The user steals and owes money. The system solves the difficulty of collecting subscription fees, and at the same time provides protection for value-added services due to multi-band scrambling. The system does not need to change the original TV network, and does not need to change the user's viewing habits. The user can be charged and managed at any time and anywhere. The project has low investment cost and high technical content, and is the best choice for the basic fee and value-added service development of the HFC network.

The high-speed DADA user control (CA) and management (SMS) system is mainly used in cable TV networks, which can effectively solve the problem of charging charges that are currently faced by wired networks, and can effectively guarantee the safe transmission of broadcast television networks and prevent them. Illegal signal access, comprehensively improve the management level of cable TV.

System implementation:

1) The first way: front-end scrambling

In this way, the computer system (user authorization and management) and the scrambling device are installed in the front-end equipment room to achieve full-network scrambling on the cable television network (can be scrambled per fiber), and the mode can implement segmentation. Scrambling (up to three segments) is convenient for value-added services, and is applicable to county and township-level cable networks for scrambling on the entire network. The schematic diagram is as follows:

2) The second way: line scrambling

In this way, the computer system (user authorization and management) is installed in the front-end equipment room, and the scrambling equipment is installed on each branch of the network to achieve localized scrambling on the cable television network, which is suitable for local and municipal cable television networks for local use. Regional charge control. The schematic diagram is as follows:

The replacement of analog TV by digital TV is an inevitable trend, but it should also be clearly seen that the realization of digital TV requires huge investment, and the household level is at least 1,000 yuan. Negative waiting can only make the difficulty worse. The application of analog TV plus descrambling system helps local cable TV management departments to collect arrears, clean up "black households", carry out pay TV business, enhance their "hematopoietic" function, and can prepare for the transition to digital TV in a down-to-earth manner. Market preparation. Digital analog TV will coexist for a long time, simulating the application of cable TV scrambling system, can avoid the demand for direct digital TV service, the hardware and software conditions are not mature enough, the program source is not rich enough, and the operation management mode Issues to be explored, etc., enable TV users to pay their viewing fees on time and cultivate the market for digital TV.
