Further, comprise up going port that provides network rings to go out function and the down going port that the data forwarding function is provided at least in said two network interfaces at least, said up going port is connected with router or switch, and said down going port is connected with other internet devices.
Further, said relay is a dpdt relay.
Further, said master chip is through the PHY network interface, links to each other with down going port with said up going port through said relay.
Further, said master chip is the chip with function of surfing the Net.
Implement the utility model embodiment, have following beneficial effect:
Adopt relay to control the power supply state between network interface and the master chip; Can make two-way interactive type STB when shutdown; Performance netting twine function; Guarantee that other internet devices go out and can normally surf the Net through the network interface ring of STB, not only energy-conserving and environment-protective, and avoided STB to occur because of the problem that long-term start work causes shortening useful life.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is that the structure of the embodiment of the utility model two-way interactive type STB is formed sketch map;
Schematic equivalent circuit when Fig. 2 is the start of embodiment of the utility model two-way interactive type STB;
Schematic equivalent circuit when Fig. 3 is the shutdown of embodiment of the utility model two-way interactive type STB.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Seeing also Fig. 1, is that the structure of the embodiment of the utility model two-way interactive type STB is formed sketch map.This two-way interactive type STB comprises: master chip 1, first relay 2, second relay 4, and uplink network port 3, descending network interface 5, wherein:
Said master chip 1 is connected with said uplink network port 3 through said first relay 2.
Said master chip 1 is connected with said descending network interface 5 through said second relay 4.
Concrete, said first relay 2 comprises: normally-closed contact 21, normally opened contact 22, moving contact 23; Said second relay 4 comprises: normally-closed contact 41, normally opened contact 42, moving contact 43.
The normally-closed contact 21 of said first relay 2 is connected with the normally-closed contact 41 of said second relay 4.
Said uplink network port 3 is connected with the moving contact 23 of said first relay 2; Said descending network interface 5 is connected with the moving contact 43 of said second relay 4.
Said master chip 1 is connected with the normally opened contact 22 of said first relay 2, also is connected with the normally opened contact 42 of said second relay 4 simultaneously.
Further, said uplink network port 3 is connected with router or switch, is used to provide network rings to go out function; Said descending network interface 5 and other internet devices such as PC, printer are connected, and are used to provide the data forwarding function.
Further, said first relay 2 and second relay 4 are dpdt relay.
Further, said master chip 1 is connected with the normally opened contact 22 of said first relay 2 through input PHY network interface; Said master chip 1 is connected with the normally opened contact 42 of said second relay 4 through encircling out the PHY network interface.
Further, the chip of said master chip 1 for having function of surfing the Net.
Concrete, see also Fig. 2, the schematic equivalent circuit during for set-top-box opening.When STB is in open state, 2 energisings of said first relay, then said moving contact 23 is connected with said normally opened contact 22, and said master chip 1 is connected with said uplink network port 3 through input PHY network interface;
Simultaneously, 4 energisings of said second relay, then said moving contact 43 is connected with said normally opened contact 42, and said master chip 1 is connected with said descending network interface 5 through encircling out the PHY network interface.
At this moment, said master chip 1 can be transmitted data through said descending network interface 5 through said uplink network port 3 accesses network, and STB has the two-way interactive function, is equivalent to a switch.
