Fig. 1 illustrates a kind of screen protection starting method schematic flow sheet that the embodiment of the present invention one provides。With reference to shown in Fig. 1, the flow process of this screen protection starting method includes:
Step 100: judge whether described intelligent terminal has signal source to input。
Concrete, in the execution process of step 100, it is judged that whether all input channels of this intelligent terminal have signal source to input, example, it is possible to detected by the mode scanned in all input channels of this intelligent terminal and whether have signal source to input。For intelligent television, the signal of intelligent television mainly includes ATV signal, DTV signal, HDMI signal, AV signal etc., wherein, example, the detection of AV signal and ATV signal can be completed by the CPU processor of intelligent television, the detection of HDMI signal can be detected by the synchronous processing device of intelligent television, and DTV signal can be detected by the digital conversion processor of intelligent television and CPU processor。
Concrete, signal source is had to input if step 100 determines intelligent terminal, illustrate that this intelligent terminal is in use state, example, if it is determined that have digital analogue signal to input in DTV (DTV) passage of intelligent television, illustrate that intelligent television is playing digital television program, or the HDMI (HDMI) determining intelligent television has anolog TV signals to input, illustrate that intelligent television is just in playing audio-video resource, now intelligent television does not present screen protection state, circulation performs step 100, until step 100 detects that intelligent television no signal source inputs, perform step 110。
Step 110: if the input of described intelligent terminal's no signal source, it is judged that whether there is user operation in preset time threshold。
Concrete, if step 100 determines the input of intelligent terminal's no signal source, illustrate that this intelligent terminal is likely to be at non-working condition, and then judge whether this intelligent terminal has user operation in preset time threshold, user operation herein can be any control instruction that user sends to intelligent television, example, user operation can be the phonetic control command that user passes through that the speech control module of intelligent television inputs to intelligent television, it can also be the control instruction of the control knob input that user passes through on intelligent television, can also is that user passes through the control instruction that remote controller inputs to intelligent television, can also is that user passes through the control instruction that the touch panel of intelligent television inputs to intelligent television, certainly it is merely illustrative of herein, the user operation not representing the embodiment of the present invention is limited thereto。
Concrete, after determining the input of this intelligent terminal's no signal source, further judge whether have user operation in this intelligent terminal preset time threshold later, this preset time threshold is the time span pre-set according to user habit, example, this preset time threshold can be 1min, it is also possible to be 30s, can also is that any time threshold value meeting user's request, the concrete time span of preset time threshold is not limited by the embodiment of the present invention。
Concrete, in the execution process of step 100 and step 110, if it is determined that input to this intelligent terminal's no signal source and no user operation in preset time threshold, then perform step 120, namely this intelligent terminal without the input of any signal source and inputs without any control instruction in preset time threshold, then perform step 120。
Step 120: if no user operation in described preset time threshold, it is judged that whether the quantity of the described intelligent terminal connected in LAN belonging to described intelligent terminal is less than predetermined threshold value。
In the execution process of step 120, this intelligent terminal determines the input of its no signal source and during no user operation in preset time threshold, and this intelligent terminal obtains the quantity of this intelligent terminal in its LAN connected。Concrete, this intelligent terminal can obtain the quantity of the terminal unit belonging to same manufacturer and described same signal in its LAN connected with this intelligent terminal；Or this intelligent terminal obtains in its LAN connected and belongs to same manufacturer with this intelligent terminal and belong to the quantity of of a sort terminal unit, does not differentiate between concrete product type；Or this intelligent terminal obtains the quantity belonging to of a sort terminal unit in its LAN connected with this intelligent terminal, do not differentiate between concrete manufacturer and product type。
Example, the intelligent television being LED55K720UC for the model of Hisense Group's production, if this intelligent television determines the input of its no signal source and no user operation in preset time threshold, first this intelligent television obtains its LAN Information connected, such as this intelligent television obtains the service set (SSID) etc. of its LAN IP address connected and this LAN, and then judges the quantity of the intelligent television connected in this LAN based on this LAN Information。Wherein, the quantity of the intelligent television that model is LED55K720UC that the Hisense Group that the quantity of the intelligent television connected in this LAN may refer to connect in this LAN produces；May also mean that the quantity of the intelligent television of the Hisense Group's production connected in this LAN, do not differentiate between the model of concrete intelligent television；Can also is that the quantity of the intelligent television connected in this LAN, do not differentiate between concrete intelligent television manufacturer and model。
Preferably, in the execution process of step 120, this intelligent terminal determines the input of its no signal source and no user operation in preset time threshold, this intelligent terminal obtains in its LAN connected and belongs to of a sort terminal unit with this intelligent terminal, does not differentiate between concrete manufacturer and product type。Example, the intelligent television being LED55K720UC for the model of Hisense Group's production, this intelligent television determines the input of its no signal source and no user operation in preset time threshold, this intelligent television obtains the quantity of intelligent television in its LAN connected, and does not differentiate between concrete manufacturer and product type。Because, intelligent television is in the process that market is shown, the quantity of the intelligent television of the same model of the same manufacturer connected in same LAN is often smaller, even in the process that market is shown, the quantity of the intelligent television of the same model of the same manufacturer connected in same LAN is only one, now, it is impossible to distinguishing this intelligent television is show in market or use in user family。But, intelligent television is in the process that market is shown, the quantity of the intelligent television of the different model of the same manufacturer connected in same LAN is relatively larger, further, intelligent television in the process that market is shown, the quantity of the intelligent television that the quantity of the intelligent television of the different model of the different manufacturers connected in same LAN is far longer than in user family to connect in LAN。
Further, this intelligent terminal can obtain the quantity of this intelligent terminal in its LAN connected by following three kinds of modes。
Method one: intelligent terminal adopts the mode of TCP poll to obtain the quantity of this intelligent terminal in its LAN connected。Concrete, this intelligent television obtains IP address and the subnet mask of himself, goes out all of IP address in its connected LAN according to the IP address of himself and subnet mask account, then uses PING method to be polled IP address one by one。Example, for intelligent television, the IP address of this intelligent television is 255.255.255.6, subnet mask is 255.255.255.0, 255 IP addresses (255.255.255.0 ~ 255.255.255.255) of existence in the LAN that this intelligent television connects can be calculated by the IP address of this intelligent television and subnet mask, and then the terminal unit foundation connection that this intelligent television is corresponding with above-mentioned IP address one by one, and then obtain the equipment identification information of this terminal unit corresponding to IP address, this equipment identification information at least includes the unit type of this terminal unit, manufacturer, one or more in device type and device name, and then judge that whether this terminal unit is identical with this intelligent television。
Method two: intelligent terminal adopts the mode of udp broadcast to obtain the quantity of this intelligent terminal in its LAN connected。Concrete, this intelligent terminal is to LAN broadcast's UDP multicast message that it connects, after the other-end equipment connected in this LAN receives this UDP multicast message, UDP response message is sent to this intelligent terminal, example, this UDP response message includes the equipment identification information of terminal unit, this equipment identification information at least includes one or more in the unit type of this terminal unit, manufacturer, device type and device name, and then this intelligent terminal judges that whether this terminal unit is same。Further, owing to the packet loss of udp broadcast is higher, therefore, this intelligent terminal can adopt the method repeatedly broadcasting averaged to obtain the quantity of this intelligent terminal in its LAN connected。
Method three: intelligent terminal can pass through to add the quantity of this intelligent terminal in its LAN connected of UsingNetworkServiceDiscovery (NSD) service acquisition。Concrete, certain conventional application program of this intelligent terminal adds NSD service, by obtain in this LAN can the quantity of NSD service judge the quantity of this intelligent terminal in this LAN。For intelligent television, the homepage of intelligent television adds NSD service, after intelligent television start, its homepage necessarily runs, and then this NSD service is registered activation, when this intelligent television needs the quantity obtaining this intelligent television in its LAN connected, this intelligent television can call the DiscoverServices of NSD service and inquire about this service, and then judges the quantity of this intelligent television connected in this LAN according to the NSD the inquired quantity serviced。
Further, this predetermined threshold value can be greater than any positive integer of 1, example, if this intelligent terminal obtains the quantity of the terminal unit belonging to same manufacturer and described same model in its LAN connected with this intelligent terminal, then this predetermined threshold value could be arranged to 2；If or this intelligent terminal obtains in its LAN connected and belongs to same manufacturer with this intelligent terminal and belong to the quantity of of a sort terminal unit, not differentiating between concrete product type, then this predetermined threshold value could be arranged to 4；If or this intelligent terminal obtains the quantity belonging to of a sort terminal unit in its LAN connected with this intelligent terminal, not differentiating between concrete manufacturer and product type, then this predetermined threshold value could be arranged to 6。Certainly being merely illustrative of, the predetermined threshold value not representing the embodiment of the present invention is limited thereto herein。
Concrete, the intelligent television being LED55K720UC for the model of Hisense Group's production, if this intelligent television obtains the intelligent television quantity that signal is LED55K720UC that the Hisense Group connected in its LAN connected produces, then this predetermined threshold value could be arranged to 2；If this intelligent television obtains the intelligent television quantity that the Hisense Group connected in its LAN connected produces, then this predetermined threshold value could be arranged to 4；If this intelligent television obtains the intelligent television quantity connected in its LAN connected, then this predetermined threshold value could be arranged to 6。
Further, it is judged that the quantity of the described intelligent terminal connected in LAN belonging to this intelligent terminal, whether less than predetermined threshold value, if the quantity of this intelligent terminal connected in the LAN that connects of this intelligent terminal is less than predetermined threshold value, then performs step 130。
Step 130: if the quantity of the described intelligent terminal connected in described LAN is less than predetermined threshold value, described intelligent terminal presents screen protection state。
After above-mentioned steps 120; determine the quantity of this intelligent terminal connected in the LAN that this intelligent terminal connects less than predetermined threshold value; this intelligent terminal presents screen protection state; example; this intelligent terminal presents screen protection state; can be the display screen display screen protection picture of this intelligent terminal, it is also possible to the display screen display screen for this intelligent terminal protects animation, it is also possible to the display screen for this intelligent terminal presents blank screen etc.。
The screen protection method that the embodiment of the present invention provides; when determining the input of this intelligent terminal's no signal source and no user operation in preset time threshold; further judge in LAN belonging to intelligent terminal; whether the quantity of this intelligent terminal connected is less than predetermined threshold value; if the quantity of this intelligent terminal connected in this LAN is less than predetermined threshold value, this intelligent terminal presents screen protection state。The screen protection method that the embodiment of the present invention provides, intelligent terminal can be prevented effectively from market displaying process, when the input of no signal source and user operation, present screen protection state and affect the comprehensive of intelligent terminal and show, because in the process that market is shown, the quantity of the identical intelligent terminal connected in same LAN is relatively more, it is usually not less than predetermined threshold value, and in the process used in user family, the quantity of the identical intelligent terminal connected in same LAN is less than predetermined threshold value, the process that intelligent terminal uses in user family can normally present screen protection state, therefore, the screen protection starting method of the embodiment of the present invention is not affecting while intelligent terminal user normally uses, the screen protection starting method solving intelligent terminal in prior art can not meet the problem that intelligent terminal carries out displaying comprehensively in market。
Intelligent terminal is in the process that market is shown, playing the image frame that a certain signal source is corresponding always, for showing the various performances of this intelligent terminal to client comprehensively, but, in the process that intelligent terminal shows, due to reasons such as client operatings, the homepage of intelligent terminal or the state of other no signal source input can be switched to, now, if the quantity that the intelligent terminal of the embodiment of the present invention determines the described intelligent terminal connected in LAN belonging to it is not less than predetermined threshold value, this intelligent terminal will not display screen guard mode, but this intelligent terminal can unanimously be in current operation interface or the state of other no signal source input, still comprehensive displaying of intelligent terminal it is unfavorable for。
Based on the problems referred to above, the another kind of screen protection starting method schematic flow sheet that Fig. 2 provides for the embodiment of the present invention two。As in figure 2 it is shown, after above-mentioned steps 110, also include:
Step 130: if the quantity of the described intelligent terminal connected in described LAN is not less than predetermined threshold value, described intelligent terminal presents the image frame corresponding to signal source used last time。
Concrete, if it is determined that the quantity of this intelligent terminal connected in the LAN connected to this intelligent terminal is not less than predetermined threshold value, this intelligent terminal presents the image frame corresponding to signal source used last time, namely this intelligent terminal show switching before image frame corresponding to signal source。Example, for intelligent television, this intelligent television is shown that the image frame that HDMI signal is corresponding before handover, after client is by its changing interface to application homepage, a period of time determines this intelligent television and inputs without any user operation, and this intelligent television determines the quantity of this intelligent television connected in its LAN connected and is not less than predetermined threshold value, then this intelligent television show before image frame corresponding to the HDMI signal of use。Or, example, still for intelligent television, the image frame that media resource that this intelligent television is shown that in movable storage device (such as USB flash disk, portable hard drive etc.) before handover is corresponding, after client is by its changing interface to application homepage, a period of time determines this intelligent television and inputs without any user operation, and this intelligent television determines the quantity of this intelligent television connected in its LAN connected and is not less than predetermined threshold value, then this intelligent television show before use movable storage device in image frame corresponding to media resource。
Because intelligent terminal is in market displaying process, businessman wishes that intelligent terminal plays the image frame that certain signal source is corresponding always, to show various performances and the effect of intelligent terminal to client comprehensively, example, for intelligent television, intelligent television, in the process that market is shown, plays the image frame that certain signal source is corresponding always, it is simple to comprehensively show the display effects such as the definition of intelligent television, contrast and color to client。The screen protection starting method that the embodiment of the present invention provides; when determining no user operation in the input of this intelligent terminal's no signal and preset time threshold; and this intelligent terminal determines the quantity of this intelligent terminal connected in its LAN connected and is not less than predetermined threshold value; then this intelligent terminal presents the image frame corresponding to signal source used last time; can avoid intelligent terminal in the process that market is shown; all the time it is in certain display interface in situation without client operating, improves the intelligent terminal's comprehensive bandwagon effect in market。
Fig. 3 illustrates a kind of screen protection starting method schematic flow sheet that the embodiment of the present invention three provides。With reference to shown in Fig. 3, the flow process of this screen protection starting method includes:
