The curve chart 410 of Fig. 5 top is that the sequential chart that display device 100 sends beacon packet b is shown.Transverse axis in figure refers to the time.Display unit 100 periodically sends beacon packet b with the predetermined interval of the rule of time t1 to the outside.
Because shutter glasses 200 uses internal storage usually, can guarantee that during the demonstration of content images the operation of shutter glasses 200 becomes problem.Especially, the power consumption that shutter glasses 200 should minimise battery 230, thereby the operating time that maximizes shutter glasses 200.
In order to realize above-mentioned situation, shutter glasses 200 receives beacon packet b according to the sequential shown in the second curve chart 420.Shutter glasses 200 receives beacon packet b from display unit 100, but with than time cycle t1(namely, the transmitting time cycle that display unit 100 adopts) interval of the rule of long time t2 receives beacon packet b.Interval t2 is not limited to specific numeral, as long as t2 is greater than t1.In some one exemplary embodiment, t2 has the default value as the multiple of t1.For example, if t1 equals 80 milliseconds, can be set to 560 milliseconds by t2, it is seven double-lengths of t1.
From receive the first beacon packet b first regularly 421 until receive second regularly during the 422 interval t2 that measure of next beacon packet b, shutter glasses 200 is forbidden glasses communication unit 210 by the electric weight that cut-out battery 230 provides, thereby do not allow glasses communication unit 210 to receive the intermediate conveyor of beacon packet b, and based on at the first information operating eyeglass 220 that regularly the first beacon packet b of receiving of 421 places is relevant.Such operation is called as free-running operation (free-run) operation.
At the second 422 places regularly, shutter glasses 200 is by allowing to provide electric weight to enable glasses communication unit 210 to receive next beacon package b from battery 230, and forbid glasses communication unit 210 after receiving next beacon packet b, in order to continue handling lens 220 under the state of free-running operation.
Particularly, shutter glasses 200 is than t1(to be, the transmitting time cycle that display unit 100 adopts) long interval t2 receives beacon packet b, and do not receive therein forbidding glasses communication unit 210 during the part of interval t2 of beacon packet b, in order to the electric power that will be provided by battery 230 is provided originally.
When shutter glasses 200 receives beacon packet b, depend on the environment for use of display system 1 and 2, the reception environment relevant to beacon packet b can change.
If glasses communication unit 210 is based on such as the operation of the RF wireless communication standard of bluetooth, may there be the various external equipments that use with the same or similar wireless communication standard of above-mentioned wireless communication standard in display system 1 and 2 environment for use.The existence of external equipment may cause with respect to the congested of radio communication or disturb.If the excessive interference with respect to radio communication is arranged, shutter glasses 200 may not can receive beacon packet b with scheduled timing.
In order to realize foregoing, according to this one exemplary embodiment, following configuration is applied to shutter glasses 200.
For based on playing and the Preset Time section of the scheduled timing of displaying contents image, shutter glasses 200 determines that display unit 100 is to the acceptance rate of the beacon packet b of glasses communication unit 210 transmissions.Shutter glasses 200 and the acceptance rate of determining change the receive frequency of the beacon packet b that is received by glasses communication unit 210 accordingly.
Determine that based on it sequential of acceptance rate and Preset Time section can the taking into account system environment and change, and be not limited to specific numeral.
The basis of determining the acceptance rate of beacon packet b can change.For example, the acceptance rate of beacon packet b can be relevant to the packet error probability that the time of glasses communication unit 210 reception beacon packet b is located.Packet error probability can be defined as the frequency that takes defeat of the grouping that receives with respect to time per unit.
Especially, the packet error probability that shutter glasses 200 is worked as beacon packet b is relatively high (for example, greater than the predetermined threshold rate) time improve the receive frequency of beacon packet b, and reduce the receive frequency of beacon packet b when the packet error probability relatively low (for example, less than the predetermined threshold rate) of beacon packet b.
More specifically, if determine that beacon packet b has many reception mistakes, shutter glasses 200 improves the receive frequency of beacon packet b, thereby improves the received quantity of time per unit beacon packet b.In order to realize above-mentioned situation, shutter glasses 200 is adjusted into interval t3 less than t2 as the acquiescence time of reception section that receives beacon packet b with sequential.In some one exemplary embodiment, interval t3 can be appointed as the multiple of t1, be similar to above-mentioned description for t2, but t3 is less than t2 and be equal to or greater than t1, as shown in curve chart 430.
If there are relevant to beacon packet b relatively many reception mistakes, that is, determine to have the relative a large amount of interference that affects radio communication in display system 1 and 2 environment for use, can be set to equal t1 by t2.
Otherwise shutter glasses 200 can determine to exist the relatively few reception mistake relevant to beacon packet.Particularly, may there be the interference of the less quantity of the radio communication that affects display system 1 and 2.Under these circumstances, shutter glasses 200 can reduce the receive frequency of beacon packet b, thereby reduces the received quantity of time per unit beacon packet b.Shutter glasses 200 can be realized the reduction of receive frequency by sequential being adjusted to the interval t4 larger than t2 as the acquiescence time of reception section that receives beacon packet b, as shown in the 4th curve chart 440.
Depend on wireless environment, shutter glasses 200 can improve the received quantity of time per unit beacon packet b in order to improve the precision of the operation of shutter glasses 200, perhaps shutter glasses 200 can reduce the power consumption of power consumption battery 230, thereby carries out the operating time that selectivity operated and optimized shutter glasses 200.
Below, with reference to the control method of Fig. 6 description according to the 3D glasses of one exemplary embodiment.Fig. 6 is the flow chart of explanation control method.
In the first operation, with 3D glasses and display unit pairing (operation S100).The 3D glasses begin to receive beacon signal (operation S110) from the display unit of pairing.
The 3D glasses are determined the acceptance rate (operation S120) of beacon signal in the Preset Time section based on unrestricted scheduled timing.3D glasses and the acceptance rate of determining change the receive frequency (operation S130) of beacon signal accordingly.
The 3D glasses receive beacon signal (operation S140) according to the receive frequency that changes, and based on the beacon signal handling lens that receives (operation S150).
In previous exemplary embodiment, shutter glasses 200 changes receive frequency and receives beacon signal.Yet the scope of the present invention's design is not limited to foregoing, and can comprise other various modifications and variations.For example, display unit 100 but not shutter glasses 200 can change the transmission frequency of beacon signal, and send beacon signal according to the transmission frequency that changes.This demonstration sight below will be described.
Fig. 7 illustrate search signal that display unit 100 sends and shutter glasses 200 transmissions to the relation between the response of search signal.
As shown in Figure 7, display unit 100 can be exported search signal with search shutter glasses 200, so that the traffic operation of realization and shutter glasses 200.For example, when the pairing completed between display unit 100 and shutter glasses 200, display unit 100 sends and reconnects tandem grouping (operation 510).Can reconnect the tandem grouping as understanding similarly this as described in reference Fig. 4, thereby detailed explanation will be omitted.
Comprise that shutter glasses 200 should receive and reconnect the tandem grouping for receiving the necessary information of beacon packet because reconnect the tandem grouping before receiving beacon packet.
Reconnect tandem grouping (operation 520) if display unit 100 successfully sends, shutter glasses 200 sends respond packet to reply the successful reception (operation 530) that reconnects the tandem grouping to display unit 100.
Reconnect tandem grouping (operation 540) if shutter glasses 200 fails to receive from display unit 100 in the Preset Time section, shutter glasses 200 resends with request to display unit 100 transmission request groupings and reconnects tandem grouping (operation 550).
Fig. 7 illustrates mutual between single display unit 100 and single shutter glasses 200, yet for example in movie theatre environment shown in Figure 2, display unit 100 is carried out aforementioned process for each of a plurality of shutter glasses 200.
According to this one exemplary embodiment, display unit 100 determines to send in display unit 100 that in Preset Time section after reconnecting the tandem grouping, a plurality of shutter glasses 200 receive the acceptance rate that reconnects the tandem grouping, and according to the transmission frequency of the acceptance rate change beacon packet of determining.
Can determine acceptance rate by several different methods.For example, can determine acceptance rate to the received quantity of the respond packet 530 of display unit 100 transmissions and the received quantity of request grouping 550 based on a plurality of shutter glasses 200 in predetermined amount of time.Reconnect tandem when grouping and send respond packet 530 when shutter glasses 200 successfully receives, send request when sending request grouping 550 when reconnecting the tandem grouping and divide into groups 550 and fail to receive when shutter glasses 200.
Therefore, the wireless communications environment that a large amount of respond packet 530 indicates display system 1 to communicate by letter with 2 usually is relatively clear, and has less interference.The wireless communications environment that a large amount of request groupings 550 indicates display system 1 to communicate by letter with 2 usually is unclear, and has more interference.Particularly, can adjust pro rata acceptance rate with the received quantity of respond packet 530, and adjust inversely acceptance rate with the received quantity of request grouping 550.
If determine that the acceptance rate of a plurality of shutter glasses 200 is high, for example, greater than predetermined threshold speed, display unit 100 reduces the transmission frequency of beacon packet, if and the acceptance rate of determining a plurality of shutter glasses 200 is low, for example, less than predetermined threshold speed, display unit 100 improves the transmission frequency of beacon packet.Thereby display unit 100 is adjusted into transmission cycle of beacon packet and is longer than default value reducing the transmission frequency of beacon packet, and transmission cycle of beacon packet is adjusted into is shorter than default value to improve the transmission frequency of beacon packet.
Especially, if relatively a large amount of interference is arranged in communication environment, display unit 100 improves the quantity forwarded of time per unit beacon packet, makes the acceptance rate of the beacon packet of shutter glasses 200 employings improve.
If the interference of relatively small amount is arranged in communication environment, display unit 100 reduces the quantity forwarded of time per unit beacon packet.Because shutter glasses 200 receives beacon packet based on the information that is sent by display unit 100, can reduce by the transmission rate that reduces display unit 100 time per unit beacon packet the acceptance rate of the beacon packet that shutter glasses 200 adopts and reduce the power consumption of shutter glasses 200.
Below, with reference to the control method of Fig. 8 description according to the display unit 100 of this one exemplary embodiment.Fig. 8 is the flow chart of its control method of explanation.
In the first operation, display unit 100 output search signal are to search at least one shutter glasses 200(operation S200).
Preset Time section after the output search signal, display unit 100 receives in response to the respond packet of search signal or again asks the request of search signal to be divided into groups (operation S210) from shutter glasses 200.
Display unit 100 is calculated the acceptance rate (operation S220) of this at least one shutter glasses 200 based on the quantity of the request grouping of the quantity of the respond packet that receives and reception.
Display unit 100 changes the transmission frequency (operation S230) of beacon signal based on the acceptance rate that calculates.Display unit 100 sends beacon signal (operation S240) according to the frequency that changes to this at least one shutter glasses 200.
Although illustrated and described several one exemplary embodiment, but it will be apparent to those skilled in the art that principle and the category that can change and do not deviate from the present invention's design that its scope limits in appended claims and equivalent thereof in these one exemplary embodiment.
