A kind of Homeplug for supporting online and the double business of IPTV to transmitTechnical field
The present invention relates to a kind of Homeplug, specifically a kind of Homeplug for supporting online and the double business of IPTV to transmit.
Background technology
Power modem device is with one of preferred embodiment that distinctive technical characterstic is always home network networking, especially nearPropulsion of the year with major operators to IPTV service, traditional WiFi networkings and netting twine networking encounter unstable networks or clothAfter the difficult bottleneck of line, Homeplug is highlighted all the more as the advantage of Network stretch function.Home network is set up using HomeplugDuring network, the up home gateway of network interface connection or MODEM network interface of female cat, sub- cat connect ustomer premises access equipment.Ustomer premises access equipmentIncluding PC, flat board, mobile terminal and IPTV set top box etc..Generally female cat only one of which, sub- cat can need according to specific networkingAsk collocation one or more, communicated between female cat and sub- cat using home power line networks.But traditionally HomeplugAs the transmission channel of network data, otherwise it is purely by way of IPTV transmission channel.If both to meet network dataTransmission meets IPTV transmission again, it is necessary to which two complete equipments are realized respectively, are significantly increased networking cost and are safeguarded complexity.
Prior art a set of equipment only meets single network data transmission function or IPTV transfer functions, needs at the same timeWant the family of the two functions to be accomplished by laying two sets of Homeplugs, cost is high, safeguard that complexity is high.And two sets of Homeplugs can bePowerline bandwidth is fought for a certain extent, causes overall performance to reduce.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of Homeplug for supporting online and the double business of IPTV to transmit, to solveThe problem of certainly being mentioned in background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of Homeplug for supporting online and the double business of IPTV to transmit, including the female cat of Homeplug and the sub- cat of Homeplug, the electric powerIt is connected between cat mother cat and the sub- cat of Homeplug by power line interface, the female cat of the Homeplug is provided with network interface and IPTVInterface, the sub- cat of Homeplug is provided with upper network interface and set top box interface.
It is used as the preferred scheme of the present invention：The network interface connects upstream gateway equipment, and the connection of IPTV interfaces is upIPTV。
It is used as the preferred scheme of the present invention：Upper network interface connection user's equipment for surfing the net, set top box interface connection IPTVSet top box.
Compared with prior art, the beneficial effects of the invention are as follows：By mode of the present invention, it is using a set of power modem deviceUser's online can be met simultaneously and IPTV transmits two kinds of business demands, the cost of investment of user's distributing network is reduced, for netAlso mitigated for network operator and safeguard complexity.
Brief description of the drawings
Fig. 1 is structure chart of the invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeSite preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based onEmbodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not madeEmbodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, a kind of Homeplug for supporting online and the double business of IPTV to transmit, including the female cat of Homeplug and HomeplugSub- cat, is connected between the female cat of the Homeplug and the sub- cat of Homeplug by power line interface, and the female cat of the Homeplug is provided withNetwork interface and IPTV interfaces, the sub- cat of Homeplug are provided with upper network interface and set top box interface.
Network interface connects upstream gateway equipment, and IPTV interfaces connect up IPTV.Upper network interface connection user's online is setIt is standby, set top box interface connection IPTV set top box.
The present invention operation principle be：When user has network data transmission and IPTV transmits two kinds of demands, by motherTwo network interfaces are reserved on cat, this two network interfaces connect the network interface and IPTV interfaces of upstream gateway equipment respectively, at sub- catBoth IPTV service can be provided by the LAN mouth dial-up connections IPTV server in sub- cat, and can also provides network access facility, this netNetwork access function includes LAN is accessed or WiFi is accessed etc..
