Abstract
The present utility model provides a low-power dissipation set top box which relates to the digital television technology field. The set top box comprises a set top box master control circuit, a button panel control circuit and a master control circuit power supply, the set top box is characterized in that the set top box also comprises a control panel power supply, and the button panel control circuit is electrically connected with the control panel power supply. When the set top box is in open state, the set top box master control circuit is power-supplied by the master control circuit power supply, and the button panel control circuit is power-supplied by the control panel power supply; thus the set top box master control circuit and the button panel control circuit are respectively power-supplied by independent power supplies. When the set top box is in standby state, the operation of operating or power-supplying a button panel is not necessary, the control panel power supply is stopped power-supplying the button panel control circuit, thus electric energy is saved.
Description
[technical field]
The utility model relates to the digital television techniques field, specifically, relates to a kind of STB of low-power consumption.
[background technology]
At present; Be applied to the STB of DTV; Under holding state, power supply supplies power for simultaneously the governor circuit of main frame and the circuit of control panel, and need supply power to the governor circuit of main frame following of holding state gets final product; Therefore, the control panel circuit supplied power during standby and wasted electric energy.
[utility model content]
The purpose of the utility model is to overcome a kind of low-power consumption STB that existing STB is supplied power and caused the deficiency of waste of electric energy to provide control panel at holding state.
The utility model is realized through following technical scheme: a kind of low-power consumption STB; It comprises STB governor circuit, key panel control circuit and governor circuit power supply; Said STB governor circuit is connected with said key panel control circuit signal, and said STB governor circuit and said governor circuit power supply electrically connect; Its improvements are that it also comprises a control panel power supply, and said key panel control circuit and said control panel power supply electrically connect.
Do further to set forth in the face of above technical scheme down:
Further, it also comprises a charging circuit; Said control panel power supply is a storage battery; The current input terminal mouth of said charging circuit and said governor circuit power supply electrically connect, and the current output terminal mouth of said charging circuit and said control panel power supply electrically connect.
The beneficial effect of the utility model is: the STB of one of which, the utility model, and when STB was opened, the governor circuit power supply was supplied power to the STB governor circuit, and the control panel power supply is supplied power to the key panel control circuit; By this, STB governor circuit and key panel control circuit have independently power supply that it is supplied power respectively; When STB the time at holding state, because need not key panel is operated, also need not it is supplied power, the control panel power supply will stop the key panel control circuit is supplied power, and therefore, practice thrift electric energy.Two, under the state of start, charging circuit charges to the control panel power supply for its power supply through the governor circuit power supply, for the control panel power supply provides applicable electric energy.
[description of drawings]
Fig. 1 is the circuit frame principle figure of the utility model.
Reference numeral: 1, STB governor circuit; 2, key panel control circuit; 3, governor circuit power supply; 4, control panel power supply; 5, charging circuit.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be further described:
With reference to shown in Figure 1; The STB of this structure; It comprises STB governor circuit 1, key panel control circuit 2 and governor circuit power supply 3; Said STB governor circuit 1 is connected with said key panel control circuit 2 signals, and said STB governor circuit 1 electrically connects with said governor circuit power supply 3; The STB of this structure also is provided with a control panel power supply 4, and said key panel control circuit 2 electrically connects with said control panel power supply 4.The STB of this structure, when STB was opened, 3 pairs of STB governor circuits 1 of governor circuit power supply were supplied power, and 4 pairs of key panel control circuits 2 of control panel power supply are supplied power; By this, STB governor circuit 1 and key panel control circuit 2 have independently power supply that it is supplied power respectively; When STB the time at holding state, because need not key panel is operated, also need not it is supplied power, control panel power supply 4 will stop key panel control circuit 2 is supplied power, and therefore, practice thrift electric energy.
Still with reference to shown in Figure 1, the STB of this structure also is provided with a charging circuit 5; Said control panel power supply 4 is a storage battery; The current input terminal mouth of said charging circuit 5 and said governor circuit power supply 3 electrically connect, and the current output terminal mouth of said charging circuit 5 and said control panel power supply 4 electrically connect.Under the state of start, charging circuit 5 charges to control panel power supply 4 for its power supply through governor circuit power supply 3, for control panel power supply 4 provides applicable electric energy.
According to the announcement and the instruction of above-mentioned specification, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to is in the protection range of the claim that also should fall into the utility model to some modifications and the change of the utility model.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the utility model is not constituted any restriction.
