Problems solved by technology

Therefore, using a set-top box that uses the same user terminal to solve broadband access services and interactive digital TV services will not only increase production costs (the set-top box needs to be equipped with an Ethernet card, etc.), but will also increase the workload of installation
As for the existing set-top boxes that cannot be directly inserted into the built-in EOC terminal, if the original set-top box is replaced only to increase broadband services, it will undoubtedly greatly increase the investment of operators
[0003] On the other hand, network access technology and set-top box technology belong to two technical systems, and the development of the two is often out of sync.

Abstract

An EOC terminal belongs to the technical field of cable televisions. The EOC terminal comprises a radio frequency connector, a data exchange chip, a wireless routing integrated unit, a wireless radio frequency interface and a wireless transmission antenna, the CABLE interface of the radio frequency connector is connected with an EOC local side, the TV interface of the radio frequency connector is connected with the radio frequency interface of a cable television set top box, the DATA interface of the radio frequency connector is connected with the data exchange chip, the wireless routing integrated unit comprises a wireless routing integrated chip, the PHY (physical) interface of the wireless routing integrated chip is connected with the data exchange chip, the WAN (wide area network) interface of the wireless routing integrated chip is connected with the wireless radio frequency interface, and the wireless radio frequency interface is connected with the wireless transmission antenna. The EOC terminal has the advantages that the EOC terminal can be added on the side of an existing reserved set top box, consequently, smooth upgrading is realized, and the initial investment cost is saved; the EOC terminal can be mounted on demand, so that the invested cost of an operator can be reduced; the wireless home coverage of cable televisions and wired Internet access is perfectly realized; and the EOC terminal is adapted to the access of a variety of networks.

Description

technical field [0001] The invention belongs to the technical field of cable television, and in particular relates to an EOC (full English name: Ethernet over COAX, Chinese name: Ethernet data transmission through coaxial cable) terminal. Background technique [0002] With the rapid development of the digital TV industry, broadcasting and television operators are transforming into comprehensive service operators by taking advantage of the opportunity of the overall conversion of digital TV. Making full use of the existing huge HFC (English name: Hybrid Fiber-Coaxial, Chinese name: hybrid fiber-coaxial cable network) basic network to expand the development of two-way transmission services (such as: broadband, digital TV, video on demand) has become The main topic of the current two-way transformation of radio and television operators. The types of technologies to achieve two-way transformation of the network will coexist in a certain period of time. At present, the main tech...
