Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings, and the HFC network will be described in detail with the CATV network.

[0042] Cable television network monitoring system such as figure 1 As shown, it includes a server and a monitoring device connected thereto, and the server and each monitoring device are connected through optical fiber, coaxial cables, and the like. The server is set at the terminal of the monitoring personnel or the maintenance personnel of the cable television network, so as to realize the monitoring of the entire cable television network. The monitoring device can be set at the node of the cable TV network, such as the cable TV program conversion point of each building or floor, and can also be set at the terminal of the cable TV program signal, such as each cable TV user terminal, which can be adjusted according to needs and actual conditions. situation is set.

[0043] The monitoring device i...

Abstract

The invention discloses a monitoring device of an HFC (hybrid fiber coaxial cable) network, and the device is used for monitoring performance information of cable television signals at a position in which the monitoring device is located and sending the performance information to a server which is connected with the monitoring device by the HFC network. The monitoring device comprises a program image monitoring module, a digital television channel monitoring module, a DOCSIS (data over cable system interface specification) channel monitoring module and an optical transceiver monitoring module. The invention also provides a monitoring method utilizing the monitoring device. According to the invention, a decoding function for high-definition programs and multi-coding modes is added, the integrated level of the DOCSIS and information source decoding is improved, and an optical transceiver monitoring function is added.

Description

technical field [0001] The invention relates to the technical field of HFC networks, in particular to an HFC network monitoring device and a monitoring method thereof. Background technique [0002] With the increasing popularization and wide application of cable TV, especially digital TV, people's lives have undergone earth-shaking changes, especially after digital TV is adopted, the TV programs that people see are clearer and more in number. There are also more consultation information and richer content, which meets people's growing spiritual and cultural needs to a certain extent. Among them, the HFC (Hybrid Fiber Coaxial Cable, fiber-coaxial cable hybrid network) network has become the most mature and market-oriented TV program transmission network in the existing technology due to its advantages of large transmission data capacity and low network architecture cost. [0003] HFC is an economical and practical integrated digital service broadband network access technolog...
