Embodiment Construction

[0038] In order to solve the above-mentioned problems in the prior art, an embodiment of the present invention provides a power control solution for EoC equipment. In the technical solution provided by the embodiment of the present invention, the EoC head-end device performs power control on the EoC terminal device according to the line attenuation (or transmission loss or line loss) and signal performance of the signal sent by the EoC terminal device, thereby realizing The EoC head-end equipment automatically controls the power of the EoC terminal equipment to reduce the impact on the TV signal and take into account the signal performance requirements. It is simple and easy to implement, and does not need to introduce additional hardware equipment such as signal attenuators, which is convenient for the laying of EoC equipment. , and there is no special requirement for EoC terminal equipment.

[0039] Generally, there are two types of devices in the EoC network, one is the EoC...

Abstract

The invention discloses an Ethernet over Coax equipment power control method and a device thereof. The method comprises the steps that: Ethernet over Coax EoC head end equipment detects line attenuation and signal performance of a signal sent by EoC terminal equipment; the EoC head end equipment judges, according to the detected signal performance and a preset signal performance threshold, whether power regulation of the EoC head end equipment is required, and regulates transmission power of the EoC terminal equipment according to the line attenuation and the signal performance of the EoC terminal equipment when the power regulation is required. According to the invention, the transmission power of the EoC terminal equipment can be automatically regulated by the EoC head end equipment according to the transmission power and the signal performance of the EoC terminal equipment, in order to reduce the interference with television signal in case of meeting certain signal performance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for controlling power of coaxial Ethernet equipment. Background technique [0002] The integration of the three networks refers to the mutual penetration and mutual compatibility of the telecommunication network, radio and television network and computer communication network, and gradually integrate into a unified information communication network. The integration of the three networks is to realize the sharing of network resources, avoid low-level redundant construction, and form a high-speed broadband multimedia basic platform with wide adaptability, easy maintenance, and low cost. Triple play is an inevitable trend in the development of modern information technology integration. [0003] With the gradual implementation of triple play, EoC (Ethernet over Cable, Ethernet over Cable) technology is widely used in broadcasting and television networks be...
