Description

Automatic search protocol 3D system and its communication protocol search method

The present invention relates to a 3D system having a function of selecting a communication protocol and a method thereof, and more particularly to a general-purpose 3D system having an automatic search protocol function, which can quickly search for a corresponding 3D communication protocol specification, which can be the same Pair of universal 3D glasses, you can watch 3D displays of different brands.

In recent years, due to the popularity of 3D (Three Dimensional) movies, the demand for 3D movies has increased, especially the 3D products have also moved from movies to 3D displays (eg 3D LCD TV). First of all, why can humans see the depth through the visual and feel the three-dimensional sense? The most important point is that the human eye can feel the depth, that is, the "depth perception"; After the information, the relative position in the three-dimensional space can be judged. Because the position of the two eyes of the person is different, the average distance between the two eyes is about 5 to 7 cm, so there will be binocular parallax when the object is seen, and the human brain will merge the two images together (convergence). ), and produce a three-dimensional feeling; and this is called "binocular cues". In addition, humans can also judge the distance of the object from the eye's adaptation to the near and far focal length, motion parallax, perspective or light and shadow, and even if the human eye has only one eye, it can judge the distance.

Therefore, in order to make a 2D (Two Dimensional) plane film into a 3D stereoscopic film, it is necessary to make the left and right eyes of the human being see different images (that is, the binocular parallax of the general object). Through brain fusion, 2D movies can become lifelike 3D movies.

In the prior art, shutter glasses are used. The basic principle of this technique is to interactively display the left eye and the screen at twice the frequency. The image of the right eye, and the glasses will dynamically shield the left and right eyes of the user, cover the right eye when the left eye image is displayed on the screen, and cover the left eye when the right eye image is displayed on the screen. Both eyes see different images. Although in this situation, no two eyes see the image at the same time, but because of the effect of the visual persistence of the human eye, it is still possible to feel that both eyes have different images, and thus a three-dimensional effect. .

The commercially available 3D display uses this technology to encode 3D images in a specific communication protocol, transmit them to the receiver of the 3D glasses via the transmitter on the 3D display, and then decode the 3D glasses to the 3D glasses. The opening/closing of the shutter glasses can be controlled according to the 3D video signal transmitted by the 3D display transmitter. However, commercially available 3D displays have a large number of brands, and their respective brands use their own brand of shutter glasses to match the communication protocols and 3D video signal transmitters built into the 3D display. In this way, when you need to view 3D images, you can only use the same brand of shutter glasses to complete the decoding, otherwise you can not complete the decoding, the shutter glasses can not see the 3D image. Therefore, when purchasing a 3D display of another brand, it is necessary to purchase the shutter glasses of the corresponding brand to complete the decoding. This not only increases the user's overhead, but also the new purchase of shutter glasses is also easy to take up space. For another example, when a plurality of people view the same brand 3D display, when using shutter glasses of different brands, the shutter protocol and the 3D display have different communication protocol codes, which makes it impossible to watch, and causes a lot of trouble.

Therefore, the present invention provides a universal 3D glasses, which can write the communication protocol of each brand specification into the main memory of the 3D glasses of the present invention, and then automatically search using the controller on the 3D glasses.

No restrictions.

Next, please refer to FIG. 2, which is a diagram showing the functional blocks of the search module of the present invention. As shown in Fig. 2, when the 3D display is already playing 3D images, the user will wear the universal 3D glasses 1 and press the power switch key 70, the controller 32 in the search module 30 will be 3D. The 3D video signal sent by the display is decoded by the communication protocol; when the general-purpose 3D glasses 1 can decode the 3D video signal sent by the 3D display, the signal receiver 20 receives the 3D video signal sent by the 3D display, so the use You can watch to see that the 3D display is already playing 3D images. If the user wears the universal 3D glasses 1 and presses the power button 70, the user still cannot watch the 3D display is already playing the 3D image, indicating that the controller 32 in the search module 30 cannot send the 3D display. The 3D video signal is decoded by the communication protocol, so it is impossible to watch the 3D display already playing 3D video. At this time, in the embodiment of the present invention, after the signal search key 40 is pressed, the controller 32 in the search module 30 performs the communication protocol of the 3D display and the communication protocol built in the main memory 34. Compare to find the appropriate communication protocol. When the controller 32 has found a communication protocol with respect to the 3D display in the main memory 34, the communication protocol is decoded by the communication protocol found: when the controller After the communication protocol is decoded, the signal receiver 20 can receive the 3D video signal sent by the 3D display and drive the right mirror 111 and the left mirror 113 to be turned on or off according to the received 3D video signal to form a complete image. 3D image.

Next, another preferred embodiment of the present invention will be described. Please refer to FIG. Since there are many brands of 3D displays, there may be hundreds of protocols built into the main memory 34. Therefore, when the user presses the signal search button 40, the controller in the search module 30 is searched. 32 will compare the communication protocol of the 3D display with the communication protocol built in the main memory 34. If each comparison takes 3 seconds, if the appropriate communication protocol is found until the 100th comparison, The user has been waiting for about 300 seconds. Therefore, in the embodiment of the present invention, an auxiliary memory 36 is further disposed. The secondary memory 36 is connected to the controller 32 and the main memory 34. In the foregoing process, when the controller 32 is already in the main memory 34. After finding the appropriate communication protocol, the controller 32 will decode the content of the communication protocol into the secondary memory 36, or create a common communication protocol in the secondary memory 36 (for example, the top 10) Dachang brand communication agreement). Therefore, in this embodiment, after the user presses the signal search key 40, the controller 32 in the search module 30 searches for the communication protocol stored in the secondary memory 36, thereby reducing the search time. If the controller 32 is unable to find an appropriate communication protocol in the secondary memory 36, it will search the primary memory 34 for the appropriate communication protocol.

Next, please refer to FIG. 3 , which is a schematic diagram of data transmission of a general-purpose 3D glasses according to another embodiment of the present invention. As shown in FIG. 3, on the universal 3D glasses 1, a USB slot 17 is disposed, and the USB slot 17 can be connected to a computer (personal computer, database, etc.) by a connection line 503. Computer slot 501, so you can directly write new communication protocol directly to main memory 34 or secondary memory 36. With the purpose of this USB slot 17, that is, the 3D display is changing with each passing day, and the manufacturer's brand and communication specifications will be more and more in the future. Therefore, the new communication protocol can be connected via the connection line 501 in this way. It is written and stored in the main memory 34 or the sub-memory 36 of the general-purpose 3D glasses 1; in addition, unnecessary communication protocols can be deleted to save the memory space in the main memory 34.

Next, please refer to FIG. 4, which is a schematic diagram of a method for the 3D system of the automatic search and frequency function of the present invention. As shown in Figure 4, when the transmitter of the display is already transmitting the 3D video signal including the communication protocol; first, please refer to step 601. At the beginning, the general-purpose 3D glasses 1 must first perform system initialization, by pressing Pressing the signal search key 40 causes the system to perform the search function. At the same time, the universal 3D glasses 1 receives the 3D video signal sent by the transmitter from the signal receiver 20. Next, proceeding to step 602, the general-purpose 3D glasses 1 first enters the secondary memory 36 to search for data. Since there is no data in the secondary memory 36 in the initial stage, at this time, the process proceeds to step 6031, and the general-purpose 3D glasses 1 The main memory 34 is searched for the corresponding communication protocol; since the communication protocol of many brands has been stored in the main memory 34; if the general-purpose 3D glasses 1 does not find a communication protocol that can be decoded, then the main memory is represented. When there is no communication agreement corresponding to the label in the body 34, it is necessary to connect the external computer 50 by USB transmission in the manner described in the above FIG. 3, and input a new communication protocol into the main memory 34; When the general-purpose 3D glasses 1 searches for the corresponding communication protocol in the main memory 34, the process proceeds to step 604. At this time, it is possible to test whether each communication protocol is correct one by one, if it is wrong (thus, the user sees If the 3D video signal played by the display is not available, the universal 3D glasses 1 will return to step 602 and, via step 6031, search for other communication protocols stored in the main memory 30 again. If you pass the universal 3D glasses 1 After the test, the current communication protocol is correct (so the user can see the 3D video signal played by the display), and then proceeds to step 605, and the universal 3D glasses 1 will determine whether the communication protocol already exists in the vice. In the memory 36; if there is no such communication protocol in the secondary memory 36, the process proceeds to step 606, the new communication protocol is stored in the secondary memory 36, and then the process proceeds to step 607 to complete the setting. Thus, when the communication protocol is already in the secondary memory 36, the process proceeds directly to step 607 to complete the setting.

The above is the first system search step, and in the second system search, the same is started in step 601, by pressing the signal search key 40 to cause the system to perform the search function. Then, proceeding to step 602, the universal 3D glasses 1 first enters the secondary memory 36 to search for data. Since the second search is performed, the secondary memory 36 has been stored in the common communication protocol, so that it is not necessary to pass the main memory. 34; then proceeds to step 6032, the universal 3D glasses 1 directly search for the communication protocol by the secondary memory 36; when the general-purpose 3D glasses 1 has searched the communication protocol in the secondary memory 36, the process proceeds to step 604, that is, the test If the search protocol is correct, if it is wrong, it means that the corresponding error (so that the user can't see the 3D video signal played by the display), the universal 3D glasses 1 will return to step 602 and via In step 6031, the general-purpose 3D glasses 1 search for other communication protocols in the main memory 32. If the communication protocol currently searched by the universal 3D glasses 1 is correct (so the user can see the 3D video signal played by the display), the process proceeds to step 605, and the general-purpose 3D glasses 1 determine whether the communication protocol has been If there is no such communication protocol in the secondary memory 36, the process proceeds to step 606, the new communication protocol is stored in the secondary memory 36, and then the process proceeds to step 607 to complete the setting. Thus, when the communication protocol is already in the secondary memory 36, the process proceeds directly to step 607 to complete the setting.

It should be emphasized here that when viewing the display as the same brand, in addition to pressing the signal search button 40 for the first time, the universal 3D glasses 1 will be started by the previous communication protocol when viewed for the second time. It is not necessary to press the signal search key 40 again. However, when changing the display of different brands or models, the communication protocol may be different, so the 3D video signal played by the display cannot be seen. In this case, the signal search key 40 must be pressed to match again. Therefore, by wearing the universal 3D glasses 1, the display of different brands or models is eliminated, and different 3D glasses need to be worn, and only the communication protocol in the main memory 34 is searched for pairing.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The patent protection scope of the invention is subject to the definition of the scope of the patent application attached to the specification.
