As shown in Figure 5, top figure 410 is that the sequential chart that is sent beacon packet b by display unit 100 is shown, and following figure 420 is that the sequential chart that is received beacon packet b by shutter glasses 200 is shown.Figure 410 and 420 in both trunnion axis represent the time.
Display unit 100 outwards sends beacon packet b once periodically at each predetermined time interval t1.
Yet, because shutter glasses 200 uses internal battery 230 usually, thus when the user watching such as film have the content of long running time the time, shutter glasses 200 may or possibly can't continued operation.Therefore, for shutter glasses 200, the operating time of growing as far as possible with acquisition by the energy of minimally consuming cells 230 is important.
For this purpose, shutter glasses 200 receives beacon packet b once at each time interval t2 from display unit 100, and t2 is the transmit time segments of display unit 100 than t1() long.If t2 is longer than t1, the length of not special binding hours interval t2.In some example embodiment, time interval t2 can be set to the default value of t1 integral multiple.For example, t1 can equal 80ms, and t2 can be set and equal 560ms, and it is 7 times of t1 length.
Therefore shutter glasses 200 active spectacles communication unit 210 not in the interval t2 of received very first time point 421 to next beacon packet b received the second time points 422 from beacon packet b does not receive beacon packet b and based on the beacon packet b handling lenses unit 220 that receives at very first time point 421.This operation is called as the free-running operation operation.
At the second time point 422, shutter glasses 200 active spectacles communication units 210 and reception beacon packet b.After receiving beacon packet b, shutter glasses 200 is active spectacles communication unit 210 and with free-running operation pattern handling lenses unit 220 not again.
Especially, shutter glasses 200 receives beacon packet b periodically with the interval t2 of the transmit time segments t1 that is longer than display unit 100, and during they do not receive the interval t2 of beacon packet b active spectacles communication unit 210 not, thereby the power consumption of saving battery 230.
Yet content images has relatively long running time if battery 230 is full of fully, shutter glasses 200 might be before completing the content images demonstration terminating operation.Especially, when content images has relatively long running time, be necessary further to save the power consumption of battery 230.
For this reason, the shutter glasses 200 according to this example embodiment has following configuration.
Shutter glasses 200 extracts the information relevant with the running time of content images from the beacon packet b that receives from display unit 100, and crosses the divide into groups receive frequency of b of glasses communication unit 210 mouse beacons based on the information exchange relevant with content images running time that extracts and be changed.
Change the receive frequency of beacon packet b by following method.
Because content images has relatively long running time, so shutter glasses 200 reduces to the receive frequency of beacon packet b lower than default value.Because described receive frequency is the number of times that time per unit receives beacon packet b, the minimizing of time of reception causes (entail) receiving cycle of long beacon packet b.
For example, in the figure 420 of Fig. 4 that shutter glasses 200 reception beacon packet b are shown, be that in the example of default value, t1 is predetermined to be 80ms at the cycle t2 that receives beacon packet b, t2 is predetermined to be 560ms.In this case, can determine the default value 560ms of t2 content-based running time.
As shown in figure 430, if be longer than with reference to running time the running time of definite content of extracting from beacon packet b, shutter glasses 200 can be adjusted into the receiving cycle of beacon packet b the t3 that relatively is longer than default value t2.With reference to above-mentioned example, shutter glasses 200 can be set to 640ms by t3, and it is 8 times of interval t1 length, thereby the receive frequency of shutter glasses 200 is reduced to lower than described default value.Therefore, reduced the number of times of time per unit active spectacles communication unit 210, thus the power consumption of further having saved battery 230.
On the contrary, if be shorter than with reference to running time the running time of definite content of extracting from beacon packet b, shutter glasses 200 can keep the receive frequency of shutter glasses 200 to equal default value.Replacedly, shutter glasses 200 can be adjusted to t2 relatively short in order to guarantee the synchronizing quality of lens unit 220, thereby the receive frequency of shutter glasses 200 is increased to higher than default value.If the dump energy of battery 230 guarantees can move the operation of back in the continued operation of the whole service time of content shutter glasses 200.
Can or move aforesaid process when beginning displaying contents image during the default time period, perhaps the cycle is carried out aforesaid process when the displaying contents image, wherein in aforesaid process, shutter glasses 200 extracts the information relevant with content images running time from beacon packet b, and changes the receive frequency of beacon packet b based on the information relevant with content images running time of extracting.
In the situation of back, beacon packet b comprises the remaining runtime of the content images of calculating according to corresponding transmitting time, and shutter glasses 200 can be adjusted described receive frequency in the remaining runtime of the content-based image of time point that receives beacon packet b.In this case, the remaining power energy of shutter glasses 200 in the time of can accurately being controlled at the displaying contents image.
Only consider that with reference to shutter glasses 200 situation of content running time described aforesaid example embodiment, but can carry out various modifications.
Specifically, the dump energy of shutter glasses 200 inspection battery 230 when obtaining the information relevant with content running time.If determine that based on the dump energy of battery 230 battery 230 can not be 200 power supplies of operation shutter glasses in the whole service time of content, shutter glasses 200 can be reduced to less than default value with the receive frequency of beacon packet b.
In addition, if determine to change accordingly running time with the content that obtains the receive frequency of beacon packet b, perhaps determine that based on the dump energy of battery 230 battery 230 can not be 200 power supplies of operation shutter glasses in whole content running time, shutter glasses 200 can be controlled definite result that error messages notifies the user to be shown.
Described error messages can comprise that indication does not guarantee the information of the operation of shutter glasses 200, the information of report battery 230 needs chargings or the information that report shutter glasses 200 needs are changed when the displaying contents image.
Described error messages can shown on display unit 100 or on shutter glasses 200.In situation, shutter glasses 200 sends to display unit 100 with the information corresponding with error messages in front, in order to show error messages on display unit 100, and display unit 100 shows image based on the information that receives from shutter glasses 200.In the situation of back, shutter glasses 200 can be presented at error messages on lens unit 220, identifies described message in order to adorn oneself with the user of shutter glasses 200.
Show between can be in due course that error messages is not in order to interrupt user's view content image.For example, shutter glasses 200 can be in the content centre of running time, but is being used for showing that the time of having a rest of advertisement shows or present error messages.
In aforesaid example embodiment, shutter glasses 200 obtains the information relevant with content images running time from beacon packet b, but can be by the described information of other method acquisition.For example, described information can be contained in (see figure 4) in query-response grouping 330, perhaps (see figure 4) in reconnecting chain link grouping 360, rather than in beacon packet b, and shutter glasses 200 can extract the information relevant with content running time from respective packets.
Replacedly, shutter glasses 200 can not extract described information from beacon packet b, but receives the independent information grouping that sends from display unit 100.
After this with reference to the control method of passing through use 3D glasses realization of Fig. 6 description according to this example embodiment.Fig. 6 is the flow chart that illustrates by the control method of using the realization of 3D glasses.
As shown in Figure 6, in operation S100,3D glasses and display unit are carried out or are created pairing.Then, in operation S110, the 3D glasses receive beacon signal from the display unit of matching.
In operation S120, the 3D glasses obtain the information relevant with content images running time from beacon signal.Then, in operation S130, the 3D glasses change the receive frequency of beacon signal based on the information relevant with running time that obtains.
In operation S140, the 3D glasses receive beacon signal with reformed receive frequency, and in operation S150,3D glasses handling lenses unit is in order to optionally transmit/stop the light of user's eyes according to the beacon signal that receives.
Can control the 3D glasses by this way.
In another example embodiment, if determine that at the time point of play content image battery 230 can not be 200 power supplies of operation shutter glasses in the remaining runtime of content, shutter glasses 200 can change by glasses communication unit 210 receive frequency of beacon signal.Replacedly, shutter glasses 200 can calculate no longer receive beacon signal but subsequently with the particular point in time of free-running operation pattern handling lenses unit.With reference to Fig. 7, this control method is described.Fig. 7 is the flow chart that illustrates by the control method of using shutter glasses 200 realizations.
As shown in Figure 7, in operation S200, shutter glasses 200 can obtain following parameter in the specific operation time:
Tr: the remaining runtime of content (unit: second (sec));
Tb: the receiving cycle (unit: sec) of beacon signal;
Pb: the power consumption (unit: MAH (mAh)) when receiving beacon signal;
Ps: the power consumption (unit: mAh/sec) of each unit interval when driving lens unit 220; And
Pg: the dump energy (unit: mAh) that stores battery 230 from the current time
Shutter glasses 200 can extract Tr from the beacon signal that receives from 100 cycles of display unit.Other parameter relates to lens unit 220, glasses communication unit 210 and the battery 230 of shutter glasses 200.Just to the unit that parameters conveniently is shown, so the unit of parameters can change according to the configuration of equipment.
In operation S210, shutter glasses 200 can go out following information by using the calculation of parameter that obtains:
[Tr*Ps]: the power consumption (unit: mAh) that drives lens unit 220 in the remaining runtime of content;
[Tr/Tb]: the quantity (unit does not stipulate) that receives beacon signal in the remaining runtime of content; And
[Tr/Tb}*Pb]: the power consumption (unit: mAh) that receives beacon signal in the remaining runtime of content.
By using above information, in operation S220, shutter glasses 200 can calculate Pr based on following equation, and it is to receive the needed electric weight of beacon signal in the remaining runtime from the current time:
Pr=[{Tr/Tb}*Pb]+[Tr*Ps] (unit: mAh)
In operation S230, shutter glasses 200 compares Pr and Pg.If Pg is greater than Pr, in operation S240, shutter glasses 200 does not change operator scheme, but keeps the current operation pattern.Yet, [if Tr*Ps]＜Pg＜Pr, as operate in S250 determined, shutter glasses 200 reduces to lower than original value by the receive frequency of glasses communication unit 210 with beacon signal in operation S260, perhaps shutter glasses 200 calculates the particular point in time that no longer receives beacon signal, and replace in operation S270, shutter glasses 200 is with free-running operation pattern handling lenses unit 220.
Especially, determine whether that [Tr*Ps]＜Pg is considered, because if in the situation that in the remaining runtime of the content of current time inoperation glasses communication unit 210, the dump energy of battery 230 is even for the inadequate words all of handling lenses unit 220 only, even do not receive beacon signal, can not guarantee the operation of shutter glasses 200.
The receiving cycle T of beacon signal can be calculated as follows:
N=[Pg-{Tr*Ps}]/Pb (unit of regulation); And
T=Tr/N(unit: sec)
N is at the possible received quantity of the beacon signal of the remaining runtime of content.In operation S260, T is increased preset multiple, thereby has reduced the receive frequency of beacon signal.
In operation S270, when battery 230 is not only given lens unit 220 power supply to 210 power supplies of glasses communication unit, determine that lens unit 220 can operate until complete the particular point in time of play content.Described particular point in time can be calculated as follows:
A=[[Pg-{Tr*Ps}]/Pb] * Tb(unit: sec)
A is time quantum, and deducts A by the termination time from the play content image and determine particular point in time.When content images reached this particular point in time, shutter glasses 200 began not receive beacon signal from particular point in time, and handling lenses unit 220 just.
Therefore, can guarantee that the user just can watch at viewed image continuously to finishing, and no matter the dump energy of the battery 230 of shutter glasses 200.
Although illustrated and described several example embodiment, it will be appreciated by those skilled in the art that, principle and the spirit of the present invention's design of the scope that is defined in appended claims and equivalent thereof do not breaking away from the situation that can change in these example embodiment.
