Embodiment Construction

[0017] The central office controller used for cable TV EOC network transformation of the present invention realizes two-way transmission on the coaxial cable of the cable TV HFC network after mixing the data baseband signal and the CATV signal, and transforms the one-way broadcasting type CATV network into A two-way, broadband, digital new access network that can adapt to multimedia services. According to the requirements of NGB, in the next 10 years, for different development stages, the bandwidth of radio and television users will gradually increase from 5-10Mbps>20-30Mbps>100Mbps, so as to ensure that home users can enjoy 1 channel of HDTV, 2 channels of SDTV and 4M at the same time. Data Internet access service, this device has the characteristics of fast wide coverage and low cost. It makes full use of the original network resources and does not need to upgrade the current network. It only needs to be installed at a single point to cover the users of the entire community...

Abstract

The invention discloses a next-generation broadcasting local-side controller modified by cable television network three-network fusion and belongs to the technical field of cable televisions. The next-generation broadcasting local-side controller comprises EOC (Ethernet Over Cable) local-side modules 1-4, radio frequency cables JP1-JP4, radio frequency seats J1-J7, joints IN1-IN4, OUT1-OUT4, AC60VIN, branch distribution plug-in units FP / FZ1-FP / FZ3, inductors L1-L36, inductors 1L1-1L8, overcurrent extension sockets CP1-CP8, discharge tubes D1-D9, capacitors C1-C29 and capacitors CC1-CC56. The next-generation broadcasting local-side controller has the advantages of small noise aggregation, high provided bandwidth, low average modification cost for each family and high reliability, is convenient in upgrade and expansion, and conforms to IP (Internet Protocol) base.

Description

technical field [0001] The invention relates to an NGB (Next Generation Broadcasting, next-generation radio and television network) local end controller used for the transformation of three networks in a cable television network, belonging to the technical field of cable television, in particular to a hybrid optical fiber coaxial cable network EOC (Ethernet Over Cable (Ethernet coaxial cable transmission head end) network transformation based on a cable TV two-way transmission equipment. Background technique [0002] On December 4th, the Ministry of Science and Technology and the State Administration of Radio, Film and Television jointly signed the "National High-performance Broadband Information Network and China's Next Generation Radio and Television Network Independent Innovation Cooperation Agreement". In the "Cooperation Agreement", the concept of NGB was first proposed, marking the The official launch of the NGB era of China Radio and Television. In the executive meet...
