Abstract
The utility model provides an EoC (Ethernet over Coax) and a digital television receiving terminal. The EoC comprises a main chip, a drive chip, a coupler, a receiving filter and a high/low-pass filter, wherein the coupler is coupled with the high/low-pass filter, the receiving filter and the drive chip respectively, and the drive chip is coupled with the main chip. The EoC is characterized in that the coupler comprises a channel which is coupled to a power line. As the channel coupled to the power line is additionally arranged in the coupler of the EoC, the EoC provided by the utility model can simultaneously realize the function of a power modem, the networking cost can be reduced, and the convenience in networking can be improved.
Description
Technical field
The utility model belongs to network communication field, relates in particular to a kind of new E OC.
Background technology
EoC (Ethernet over COAX, the ether data are through the coaxial cable transmission) mainly is converted into network signal with the signal on the cable.Use the existing digital tv network local area network (LAN) mode that founds a family to use an EoC, two electric power cable modulator-demodulators could be realized a computer to access the Internet, and cost is than higher.Specifically please refer to Fig. 1, Fig. 1 carries out the application scenarios figure that local area network (LAN) is built for using existing EOC.LAN comprises EOC main frame 101, EOC equipment 102, electric power modem 103, STB 104 and computer 105.EOC main frame 101 is coupled to EOC equipment 102 through cable, and EOC equipment 102 can be coupled to STB 104 through cable, in addition, can also be coupled to electric power modem 103 through netting twine.Can know that from Fig. 1 need two electric power modems 103 could realize computer 105 access internet, cost is higher.Existing EOC is converted into network signal with the signal on the cable, need draw in the net line when forming family lan, if in different rooms, netting twine can be very long, and is very inconvenient.If directly use the mode of two EOC, need the line television interface be installed at chummery not, directly draw power line for the room that this interface is not installed, very inconvenient.
Summary of the invention
In view of this, a kind of new E OC need be provided, the convenience that can reduce networking cost and improve networking.
The utility model provides a kind of EOC; Comprise master chip, chip for driving, coupler, receiving filter and high-pass and low-pass filter; Said coupler couples with said high-pass and low-pass filter, said receiving filter and said chip for driving respectively; Said chip for driving and said master chip couple, and it is characterized in that: said coupler comprises the passage that is coupled to power line.
More excellent, said master chip is coupled to memory.
More excellent, said memory is in order to store configuration files.
More excellent, said configuration file comprises EOC configuration file and electric power modem configuration file.
The utility model also provides a kind of receiving terminal for digital television, it is characterized in that, comprises any described EOC like claim 1-4.
Because the newly-increased passage that is coupled to power line in the included coupler of this EOC, thereby make the utility model EOC can realize the function of electric power modem, the convenience that can reduce networking cost and improve networking simultaneously.
Description of drawings
Fig. 1 carries out the application scenarios figure that local area network (LAN) is built for using existing EOC.
Fig. 2 is the EOC block diagram of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 2, Fig. 2 is the EOC block diagram of the utility model.As shown in the figure, after radio frequency (hereinafter to be referred as RF) signal inserted from high-pass and low-pass filter 201, through high-pass and low-pass filter 201 filtering, high-frequency signal got into STB 202, and low frequency signal gets into coupler 203.In this embodiment, the high-frequency signal that gets into STB 202 comprises TV signal, and STB 202 can be handled to televise this high-frequency signal; The low frequency signal that gets into coupler 203 comprises network signal, can support to be coupled to the STB online of master chip 208 after handling through master chip 208.
Low frequency signal gets into receiving filter 205 through coupler 203 coupling backs, and receiving filter 205 filtered signals are sent to the analog-to-digital converter (hereinafter to be referred as A/D) 2082 in the master chip 208 through chip for driving 206.208 pairs of received signals of master chip are handled the STB that is coupled to master chip 208 to be sent to.Accordingly; The digital signal that master chip 208 will receive from the STB that couples with it is sent to chip for driving 206 through digital to analog converter (hereinafter to be referred as D/A) 2081, carries out data interaction through coupler 203 coupling backs with high-pass and low-pass filter then.
Can know that according to above description the utility model EOC realizes the bidirectional data interaction path through master chip 208, chip for driving 206, coupler 203 and receiving filter, to realize the network data two-way interactive.
Wherein, in the utility model preferred embodiment, coupler 203 also comprises a passage 2031, and passage 2031 is coupled to power line 204.In this embodiment, the low frequency signal that gets into coupler 203 then can get into power line 204 through passage 2031, to realize the network data two-way interactive through power line 204.Therefore, new E oC can use in the presence of EoC, also can work as electric power modem and use.
In addition, memory 207 is coupled to master chip 208, in order to the storage configuration file.Configuration file comprises EOC configuration file and electric power modem configuration file.In the utility model one embodiment, the MDU Configuration in the configuration file is arranged to Slave, communication Medium is set to coax-only, then can be used as EOC and uses.Equally the MDU Configuration in the electric power modem configuration file is arranged to Slave; Communication Medium is set to Powerline; Electric power modem just can use in the presence of EoC like this, links to each other with the EoC main frame with cable through power line.This mode has been practiced thrift cost on the one hand, has avoided backguy on the one hand.The program request of STB and the function of surfing the Net of other room computers have been realized simultaneously.
In another embodiment of the utility model, the MDU enable in the new E oC configuration file removed to get final product, this moment, modified model EoC can use in the presence of electric power modem.The STB of this moment electric power modem capable of using is realized the function of program request and IPTV.
