Embodiment
Technical problem underlying to be solved by this invention is: how to realize the PVR reservation when the PVR set-top box is in holding state, automatically wake the PVR set-top box up when time of PVR reserve requests is arrived and carry out the PVR reserve requests, make the PVR set-top box be in the holding state of low-power consumption as far as possible, reach energy savings and the technique effect that is user-friendly to.
As shown in Figure 1, the disclosed PVR set-top box of present embodiment comprises: realize comprising that Digital Television receives and the motherboard circuit 10 of PVR function; Be used to provide the power circuit 20 of working power; Be used to receive the front panel circuit 30 that remote signal is controlled described motherboard circuit 10 and 20 work of described power circuit, described control circuit 30 comprises that infrared receiving circuit 31, interface circuit 33, charactron show and key scanning circuit 34 and control circuit 32.
When the PVR set-top box was in normal operating conditions, described control circuit 32 did not respond remote control command and key command, chip selection signal and data content that its detection is transmitted by described motherboard circuit 10.When the user sends the standby request instruction by remote controller or button after, receive this standby request instruction or receive this standby request instruction by demonstration of the charactron in the described front panel circuit 30 and key scanning circuit 34 by the infrared receiving circuit in the described front panel circuit 30 31; And described motherboard circuit 10 instructs by scanning and the interface circuit 33 acquisition standby request in the described front panel circuit 30.
When described motherboard circuit 10 detects the standby request instruction, described motherboard circuit 10 is done following processing: choose control chip with chip selection signal (CS) output high level earlier, under clock sync signal (CLK), will comprise that by data transfer signal (DATA) system information of PVR reserve requests sends described control circuit 32 to; After the communicating pair data transmit end, after described control circuit 32 confirms that the information that receives is standby request information, send low level control signal (CONTROL), the stand-by circuit 21 in the described power circuit 20 starts, and makes described power circuit 20 enter the holding state of low-power consumption.During this period in order to guarantee the accuracy of time, described control circuit 32 can make the PVR set-top box enter normal operating conditions by of short duration output high level, so that described control circuit 32 carries out time calibration with described motherboard circuit 10, continue to make the PVR set-top box to enter holding state after finishing calibration.Though machine has had machine in the process of standby, this time is quite short, adds after the real standby power consumption of the machine 0.5W that only has an appointment, so consume the requirement of power consumption less than 1W during can satisfying standby generally fully.
In addition, after the PVR set-top box enters holding state, the real-time time timing that described control circuit 32 is sent here according to described motherboard circuit 10, when the time of PVR reserve requests arrives, pass to described stand-by circuit 21 by the control signal that described control circuit 32 sends high level, make described stand-by circuit 21 close and control and wake described power circuit up, thereby wake the PVR set-top box up; And described motherboard circuit 10 is carried out described PVR reserve requests, finishes reservation PVR function by USB interface.
In addition, the standby wakeup function is similar with the realization of reservation PVR in fact, by described control circuit 32 self-clockings, to the time chien shih PVR set-top box of subscribing enter the state of operate as normal automatically from holding state.
In conjunction with Fig. 2, described infrared receiving circuit 31 comprises: the infrared receiving terminal IC081 that is used to receive infrared remote-controlled signal; Constituted the cobasis homophase by transistor Q094, resistance R 098, R099, R704 and R071 and amplified buffer circuit, mainly solved under holding state because the infrared receiving function that draws the described control circuit 32 of current affects of described motherboard circuit 10.Described motherboard circuit 10 can receive all signals from described infrared receiving circuit when operate as normal.
In conjunction with shown in Figure 3, described control circuit 32 comprises: control chip IC01, and gating signal (CS) the institute gating that it is sent by described motherboard circuit 10, this control chip IC01 are MCU, DSP, PLD, FPGA or other programmable little process chip; Resistance R 102 and capacitor C 086 constitute reset circuit; Circuit RN64 and RN65 and transistor Q096 form inverter, and the output of inverter is as Opportunity awaiting control for linear signal (CONTROL).Inverter output high level makes the PVR set-top box enter holding state when the inverter output low level during operate as normal.
In addition, when operate as normal, the infrared ray of described control chip IC01 receives pin SW1 and SW2 is input state and presents high resistant, pin HIGH output low level, therefore charactron shown in Figure 5 is shown and key scanning circuit without any influence; And the standby button KN088 in standby button (STANDBY) connection layout 5 of described control chip IC01; Behind the PVR set-top box standby, infrared ray receives pin SW1 output low level, pin HIGH exports high level, infrared ray receives pin SW2 and is still read states, and when standby button KN088 does not press down, infrared ray receives the pin SW2 high level that reads back, and when infrared ray received pin SW2 and detects low level, described control chip IC01 just made the PVR set-top box enter normal operating conditions by the control signal of output low level.
In conjunction with shown in Figure 4.During operate as normal because the control signal (CONTROL) of described control chip IC01 output is a high level, so transistor Q095 conducting and from the emitter output voltage to circuit supply shown in Figure 5; During standby,,, be cut off for the supply access of circuit shown in Figure 5 so transistor Q095 ends because the control signal (CONTROL) of described control chip IC01 output is a low level, thus the unnecessary power consumption that reduces.
In conjunction with shown in Figure 5.When charactron demonstration and key scanning circuit 34 operate as normal, described motherboard circuit 10 can receive the information of all buttons.In addition, indicator light (green) LED081's chip for driving (DIVER IC) IC080 can brighten in operate as normal and when locking current program, can brighten when entering holding state rear indicator light (redness) LED082; Diode DN01 and DN02 prevent that the standby after-current from pouring in down a chimney from chip for driving IC080.
To sum up, under the situation of the present invention's existing circuit in utilizing the PVR set-top box as far as possible, by the control circuit that uses little process chip able to programme to realize, control it and under holding state, preserve PVR reserve requests information, and by the control circuit self-clocking, arrive when the time of PVR reserve requests, control wakes the PVR set-top box up and carries out the PVR reserve requests, thereby realizes the PVR reservation under the holding state of low-power consumption.Therefore, the present invention not only makes the PVR set-top box remain on low power consumpting state and save the energy, has also improved the intelligent degree of PVR set-top box, and more convenient user uses.
