Embodiment
As shown in Figure 1; In the building-block of logic of audio & video equipment embodiment one of the present invention; Audio & video equipment 100 can be STB, DVD etc.; This audio & video equipment 100 comprises SCART interface 110, row synchronizing separator circuit 120 and MCU 130, and wherein, this audio & video equipment 100 is connected with TV through SCART interface 110; The 20th pin of SCART interface 110 (composite video terminal) connects the input of row synchronizing separator circuit 120, and the output of row synchronizing separator circuit 120 connects the GPIO mouth of MCU 130.
When TV in working order the time; The 20th pin output composite video signal (CVBS) of SCART interface 110; Row synchronizing separator circuit 120 is isolated line synchronizing signal with composite video signal; Row synchronizing separator circuit 120 can be differential circuit, and isolated line synchronizing signal is a pulse signal, the pulse signal that just can detect the variation of height rule of MCU 130; When TV during at standby or off-mode, the 20th pin of SCART interface 110 does not have composite video signal output, the output of row synchronizing separator circuit 120 pulse-free signals, and MCU 130 just can detect lasting low level.MCU 130 judges that according to detected level state TV is to be in start or holding state then; And get into corresponding state according to the State Control audio & video equipment of the TV that is detected 100; Be specially: when audio & video equipment 100 current during at open state; If its MCU 130 detects pulse signal, then keep its open state; Do not detect pulse signal if its MCU 130 has, then control audio & video equipment 100 and get into holding state from the work at present state.Current during when audio & video equipment at holding state, if having, its MCU 130 do not detect pulse signal, then keep its holding state; If its MCU 130 detects pulse signal, then control audio & video equipment and get into operating state from current holding state.
Building-block of logic at the audio & video equipment embodiment of the present invention two shown in Fig. 2; This audio & video equipment 200 comprises SCART interface 210, row synchronizing separator circuit 220, MCU 230, module 240 and memory module 250 is set; Wherein, SCART interface 210, row synchronizing separator circuit 220, MCU 230 respectively with audio & video equipment embodiment one in SCART interface 110, row synchronizing separator circuit 120, MCU 130 similar, do not do at this and to give unnecessary details, below its difference only is described.
Need to prove, more than be specific embodiment of the present invention, is not limited to the present invention, and for example, row synchronizing separator circuit 120,220 is replaceable be the field synchronization split circuit, and correspondence is that line synchronizing signal then becomes field sync signal therewith.
In the flow chart of the method for start-up and shutdown embodiment one of the audio & video equipment of the present invention shown in Fig. 3; In the present embodiment; The audio & video equipment that links to each other with TV is a STB, and the concrete steps of the method for start-up and shutdown of this STB are following: when STB in working order the time, at first get into step S101; Detect line synchronizing signal in real time; This line synchronizing signal be by the composite video signal of the 20th pin of SCART interface output through the resulting separation of row synchronizing separator circuit, if TV is in running order, this line synchronizing signal is the pulse signal that the height rule changes; If TV is in standby or off-mode, then the low level for continuing does not promptly have line synchronizing signal.Get into step S102 then, judge whether to detect line synchronizing signal, if, then turn to step S101, continue to detect line synchronizing signal; If not, then turn to step S103.In step S103, get into holding state from the work at present state.When STB during at holding state, at first get into step S201, detect synchronizing signal in real time.Get into step S202 then, judge whether to detect line synchronizing signal, if not, then turn to step S201, continue to detect line synchronizing signal; If then turn to step S203.In step S203, get into operating state from current holding state.
In the flow chart of the method for start-up and shutdown embodiment two of the audio & video equipment of the present invention shown in Fig. 4; Wherein, Step S303, S304, S401, S402, S403 respectively with the method for start-up and shutdown embodiment one of audio & video equipment in step S101, S102, S201, S202, S203 identical; Do not do at this and to give unnecessary details, below its difference only is described.
In step S301, receive the standby delay time that the user is provided with, for example in custom menu, do " standby delay time " option, the user can import the standby delay time of setting through remote controller, as is 30 seconds; Get into step S302 then, store set standby delay time.Under open state, do not detect line synchronizing signal if having, then get into step S305, the delay idle delay time, as delayed time 30 seconds, get into step S306 then, get into holding state from the work at present state.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
