Embodiment Construction

[0045] The following detailed description in conjunction with the accompanying drawings can clearly understand this patent.

[0046] This patent adopts the combination of computer front-end authorization CA and SMS user management, and at the same time adds a specific algorithm to scramble and encrypt the digital TV signal and analog TV signal to form a scrambled digital and analog TV signal. See the attached picture (a) of 1, when the scrambled signal is transmitted on the main line, when the scrambled signal arrives at the distribution network, the authorizer is separated from the terminal card machine and sent to the home. Functions are air-separated, which is true separation. The separated functions of descrambling, decryption, and user management are strictly managed and controlled by the network operator, and the user has no card in hand. The digital set-top box in the user's home only completes demultiplexing and decompression, and the one without interface does not ne...

Abstract

The method comprises: in the EPON network built by combining Ethernet and Passive optical network (PON), the authorizing manager is used to replace the network bridge in order to realize the free transmission between Ethernet and cable TV network. It has the advantages of EPON and authorizing manager so as to realize the multi functionalities of wideband access, watching TV, on-line and making telephone.

Description

technical field [0001] The invention belongs to network communication technology. It involves the two-way transformation of cable TV HFC optical fiber coaxial network, the access method to achieve the integration of three networks (cable TV network, data network, communication network), and the equipment used to realize the method, so as to realize broadband access for users , Watching TV, surfing the Internet, and making phone calls do not interfere with each other and can be performed simultaneously. Background technique [0002] In recent years, the development and application of triple play has become a hot spot in the IT industry. The technical solutions based on the cable TV network are as follows: [0003] 1. CM access technology: Cable Modem technology has been applied both at home and abroad, but the transformation cost of the cable TV network is high, and the single access cost may be as high as 3,000 yuan / line. The transformation must transform the branch tree t...
