Abstract
Provided is an EOC device with a branch distribution function, which allows a cable television branch distributor and an EOC device to be combined to be one device. The EOC device with a branch distribution function has functions of single-path network signal input, single-path television signal input and multi-path mixed signal output. Network signals are converted into multi-path network signals via a switch module 1. Television signals are converted into multi-path television signals via a distribution module 2. The network signals of each path and the television signals of each path are mixed in a filtering module 3, so that mixed signals are obtained and are output to a terminal user device via a coaxial cable.
Description
Technical field
The utility model relates to a kind of novel EOC equipment, has particularly related to the EOC equipment of TV signal finger assignments function integrated.
Background technology
EOC (Ethernet over Coax) technology is a kind of technology that Ethernet data is transmitted through coaxial cable.Original EOC equipment adopts the input of one tunnel TV signal to mix with one road ethernet signal aspect the transmission of TV signal more, and corresponding one the tunnel mixes the method for exporting carries out the transmission of signal.But terminal use's increase, this scheme make local side apparatus all have a lot of limitation in various aspects such as manufacturing cost, volume, constructions.For improving this situation, need EOC equipment can realize the finger assignments function of TV signal.
Summary of the invention
The purpose of the utility model is to provide a kind of EOC equipment that can realize TV signal finger assignments function.Thereby realize uniting two into one of cable TV branch distributor and EOC equipment.Realize the input of one-way network signal, the input of single channel TV signal, the function of multichannel mixed signal output.
The purpose of the utility model is achieved in that the input of single channel ethernet signal is converted into the multichannel ethernet signal through the ether switch module with the single channel ethernet signal; The single channel TV signal is converted into multi-channel TV signals through signal distribution module with the single channel TV signal; Each road network network signal and TV signal are mixed through filtration module, keep useful information separately, remove interference noise; Export each road mixed signal to terminal through coaxial cable at last.
The advantage of this utility model is, can realize the input of single channel TV signal and network signal, the output of multichannel mixed signal.
Description of drawings
Fig. 1 is the utility model signal transmission sketch map;
Embodiment
Below in conjunction with accompanying drawing, the power interface new structure of the utility model is done further explain.
As shown in Figure 1, network signal is converted into the multi-channel network signal through switch module 1, is sent to the inner filtration module of EOC, keeps the frequency content of 0-45MHz in each road network network signal.TV signal is converted into multi-channel TV signals through distribution module 2, is sent to the inner filtration module of EOC, keeps the frequency content in the 60MHz-800MHz in each road TV signal.Each road network network signal mixes in filtration module 3 with each road TV signal mutually, obtains mixed signal at last, exports end user device to through coaxial cable.
Claims (4)
1. the EOC equipment of band finger assignments function mainly comprises switch module, distribution module, several big modules of filtration module, is primarily characterized in that: the input of single channel ethernet signal is converted into the multichannel ethernet signal through the ether switch module with the single channel ethernet signal; The single channel TV signal is converted into multi-channel TV signals through signal distribution module with the single channel TV signal; Each road network network signal and TV signal are mixed through filtration module, keep useful information separately, remove interference noise; Export each road mixed signal to terminal through coaxial cable at last.
2. a kind of EOC equipment with the finger assignments function according to claim 1 is characterized in that through switch module, and the one-way network signal is converted into the multi-channel network signal.
