For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed to existing issue; there is provided a kind of by automatically detecting the technical scheme that HDMI high speed signal opens and closes to realize TV; wherein; HDMI is adopted to transmit digital signal without the need to carrying out D/A or analog/digital conversion; data transfer bandwidth up to 5Gbps can be provided; and supporting the video of a road 1080p and the audio signal of 8 sound channels, new standard HDMI1.4 can provide the bandwidth up to 10G.HDMI mainly comprises 3 for transmitting the TMDS transmission channel of data, also has 1 independently TMDS clock lane.
The embodiment of the present invention provides a kind of device controlling display device, as shown in Figure 2, comprising:
Detection module 101, for exporting the first control signal when the picture signal of display device being detected, this first control signal arrives a control module 102;
Control module 102, for switching according to described first control signal and maintaining the operating state of display device; In described operating state: allow the signal transmission from outside to pass through during on-state, forbid when being in the lock state that described signal transmission passes through.
The technical scheme provided is provided, detection module 101 does not rely on manual operation and triggers, but export the first control signal in real time when the picture signal of display device being detected and be sent to control module 102, therefore trigger control module 102 that can be real-time when display device receives picture signal, allowed to pass through from the signal transmission of outside by this control module 102, now display device broadcasting signal transmission shows corresponding picture, avoids the defect that the switching on and shutting down process of watching in program process is loaded down with trivial details and repeat.
Display device comprises high definition television machine, computer screen and other can the equipment of display frame content.
Following display device specifically adopts television set; Signal transmission is the data channel signal that HDMI exports, or clock lane signal; Described signal transmission formed after the HDMI controller conversion being arranged in TV can identify by TV and the picture signal play.
In embodiment as shown in Figure 3, control module 102 comprises power supply gate 104 and signal shifter 105, wherein:
Power supply gate 104, for being switched to power supply state when receiving described signal transmission, connects the power circuit of powering to TV under described power supply state;
And,
Signal shifter 105, for allowing the signal transmission from outside to pass through when being in on-state, and forbids that when being in the lock state signal transmission passes through;
Detection module 101 is specially detection control circuit 103, described detection control circuit 103 is for exporting the first control signal when the picture signal of TV being detected, and this first control signal arrives described signal shifter 105 place and controls described signal shifter 105 and be in described lock-out state, and this first control signal arrives described power supply gate 104 place as described signal transmission, controls described power supply gate 104 and is in power supply state.
Signal shifter 105 is specially relay, optical coupling switch or alternative selector; Described power supply gate 104 is specially power supply switch tube; Described detection control circuit 103 is specially micro-control unit.
Signal transmission is the data channel signal that HDMI (High Definition Multimedia Interface) HDMI exports, or clock lane signal.
Detection control circuit 103 also comprises: the second detection control circuit, and for exporting the second control signal when described picture signal not detected, this second control signal arrives described signal shifter 105 place and controls described signal shifter 105 and be in on-state; And this second control signal arrives power supply gate 104 place controls described power supply gate 104 and be in off-position; Described power supply gate 104, also for being switched to described off-position when receiving described second control signal, disconnects the power circuit of powering to TV under described off-position.
The device controlling display device is specially the Set Top Box be connected with television set.In embodiment as shown in Figure 4, automatically detect HDMI high speed signal between TV-set top box and TV in the following way and open and close to realize TV, comprising:
Step 301, Set Top Box and TV main system are in non-transformer supply condition.
Step 302, user opens the mains switch of Set Top Box, and export signal transmission to TV by HDMI, wherein, signal transmission is specially televised image data signal.
Step 303, the HDMI_CLK-bus of HDMI has lasting clock lane signal.
Step 304, signal shifter 105 is default is on-state, and does not receive the first control signal from detection control circuit 103, is therefore in on-state.
Therefore described clock lane signal directly can arrive power supply gate 104 place by signal shifter 105, and controls power supply gate 104 and be switched to or maintain power supply state; Now, power circuit is connected as TV is powered by power supply gate 104, and TV powers on start.
Step 305, HDMI receives after controller powers on and starts normal received television program data.
The HDMI of TV receives controller output image signal.
Step 306, detection control circuit 103 now normally works because TV powers on, and detect that the HDMI of TV exports the first control signal when receiving the picture signal of controller output, first control signal arrives described signal shifter 105 place and controls described signal shifter 105 and be in the lock state, and namely forbids that signal transmission on HDMI_CLK-is through signal shifter 105; And this first control signal arrives described power supply gate 104 place as signal transmission, locks described power supply gate 104 and is in power supply state.
Step 307, after user finishes watching TV, only need to close Set Top Box, now HDMI no longer receives controller to the HDMI of TV and exports signal transmission.
HDMI receives controller owing to not receiving signal transmission, then the picture signal that HDMI reception controller exports there will be the situation that output is 0 always.
Step 308, when detection control circuit 103 detects that picture signal is 0 in the given time always, show Set Top Box shut down-namely user wish closing television, perform and lock control signal removed.
Step 309, power supply gate 104 is deenergization input because lock control signal removes, and TV entirety realizes shutdown, and TV main system reverts to non-transformer supply condition.
The technical scheme that application above-described embodiment provides, by detecting in real time the signal transmission that HDMI exports in power free situation, switching according to testing result, can well realize the function opening and closing automatically TV between different states.
In above-described embodiment, described signal transmission is data channel signal or the clock lane signal of HDMI output.
As shown in Figure 5, signal shifter 105 is specially relay, optical coupling switch or alternative selector;
