Embodiment
Technical scheme is for a better understanding of the present invention described embodiment provided by the invention in detail below in conjunction with accompanying drawing.
The embodiment of the invention provides a kind of television set automatic wake-up circuit, as shown in Figure 1, comprise CPU, described CPU connects the output of anti-phase comparator N1, the plus earth of described anti-phase comparator N1, the negative pole of described anti-phase comparator N1 connects an end of resistance R 1, the other end ground connection of described resistance R 1 by capacitor C 1 (generally can not surpass 1U).In addition, anti-interference in order to make better current limliting in a further embodiment, this circuit can also comprise: described CPU is by the output of the anti-phase comparator N1 of resistance R 3 connections, and described CPU is by C2 ground connection.Capacitor C 1 is come the vision signal coupling of set-top box, (mainly play current limliting through resistance R 2 after vision signal is come then, anti-interference effect) enters anti-phase comparator N1, the plus earth of anti-phase comparator N1, its operation principle is: when input signal during greater than 0V, output signal is for negative, when input signal during less than 0V, just is output as.The interrupt signal of anti-phase comparator N1 output enters the middle fracture of CPU through resistance R 3 and capacitor C 2.CPU can judge by the centering fracture.
The circuit that the embodiment of the invention provides utilizes the synchronous head in the vision signal to wake video TV up, because the signal section branch of vision signal changes according to picture material, but the synchronous head part is constant substantially, for negative sense-0.2V about, should this utilize this signal, through an anti-phase comparator N1 signal is amplified collection, thereby obtain the interrupt signal that we want.Utilize this interrupt signal to wake television set up, carry out normal program and play.
In addition, the embodiment of the invention also provides a kind of television set automatic awakening method, comprises the television set automatic wake-up circuit that the foregoing description provides, and as shown in Figure 2, the method comprising the steps of:
201, when television set is in holding state, detect whether interrupt signal is arranged (be high level in the present embodiment, in other embodiments also can low level, from the interrupt signal of anti-phase comparator N1), if having, then CPU counts; Further among the embodiment, this method also further comprises step: if do not detect interrupt signal, then described CPU is in interrupt status.
202, judge whether described counting reaches the number of setting;
CPU can calculate the umber of pulse of this pin in 1 second, because the line period of China's regulation is 64us, therefore, 1 second, the quantity of expert synchronous head probably was 15625, in actual count, set if 1 second count value surpass 10000, CPU just admits for signal is arranged.
If 203 described countings reach the number of setting, then wake described television set up and enter normal operating conditions.
Television set enters the state of normal play, and plays the content of this passage.If inside counting in 1 second does not reach 10000, know so to be re-set as interrupt status by register, wait for the arrival of next interrupt signal.That is: in a further embodiment, if described counting does not reach the number of setting, then the zero clearing register is re-set as interrupt status, and whether detect has interrupt signal.
Among the further embodiment, described step 202: judge that whether described counting reaches after the number of setting, further comprises step: described number is stored in the register.
The embodiment of the invention also provides a kind of television set, and as shown in Figure 3, it comprises this television set:
Detecting signal unit 301 is used for when television set is in holding state, and whether detect has interrupt signal;
Judging unit 303 is used to judge whether the counting of described counting unit 302 reaches the number of setting;
Further among the embodiment, this television set also comprises: memory cell 305 is used for the number that described counting unit 302 is counted is stored in register.
Further among the embodiment, this television set also comprises: reset cell 306, be used for not reaching the number of setting when described counting, and then the described register of zero clearing is re-set as interrupt status, and whether detect has interrupt signal.
More than the automatic awakening method of a kind of television set, circuit and television set that the embodiment of the invention provided are described in detail, for one of ordinary skill in the art, thought according to the embodiment of the invention, part in specific embodiments and applications all can change, in sum, this description should not be construed as limitation of the present invention.
