专利摘要:
The present invention relates to an electronic device that identifies that it will transmit a matrix code to a display device. In this circumstance, the electronic device transmits a signal to a matrix code reader. The signal instructs the reader to perform a matrix code capture action, such as issuing an alert, starting an optical reader, opening a capture application, and so on. The electronic device evaluates one or more conditions before transmitting the signal and the reader evaluates one or more conditions before taking action. The electronic device can transmit the signal to any reader within a communication range, only to readers in a matrix code reader list, and so on. In addition, the reader can transmit an acknowledgment message to the electronic device by capturing a matrix code after receiving a related signal, thus confirming that the matrix code has been successfully captured.

DESCRIPTIVE REPORT REFERENCE TO RELATED REQUESTS
[001] This Patent Application pursuant to the Patent Cooperation Treaty claims priority to United States Application No. 12/984,385, filed on January 4, 2011, entitled "ASSISTING MATRIX CODE CAPTURE BY SIGNALING MATRIX CODE READERS", the contents of which are incorporated into this document by reference in its entirety. FIELD OF THE INVENTION
[002]In general terms, the present invention relates to matrix codes and more specifically to matrix code capture assisted by signaling to matrix code readers when the matrix codes will be displayed. SUMMARY
[003] The present invention discloses systems and methods to help capture matrix codes thanks to signaling to matrix code readers. An electronic device (such as a decoder, a television, an appliance, and so on) identifies that it will transmit a matrix code to a display device. Based on the identified matrix code, the electronic device determines the transmission of a signal to one or more matrix code readers (such as smartphones, mobile computing devices, and so on). Once received, the signal instructs the one or more matrix code readers to perform one or more actions associated with capturing the matrix code. These actions include, but are not limited to, issuing an alert, starting a machine-readable device, opening a matrix code capture application, and so on. Thanks to the assistance provided by the electronic device, the matrix code reader user is better prepared to capture a displayed matrix code and is therefore more likely to take advantage of the functionality associated with it.
[004] In some implementations, the electronic device transmits the signal for a certain period of time before transmitting the matrix code to the display device, such as ten seconds, one minute and so on. However, in other implementations, the electronic device transmits the signal at approximately the same time as it transmits the matrix code or even after that. The electronic device can transmit the matrix signal using several different wired and/or wireless communication links, such as a communication link via Bluetooth®, a communication link via WiFi and so on. In various implementations, the electronic device transmits the signal to any matrix code reader within a communication range of the communication link used for transmission. However, in other implementations, the electronic device transmits the signal only to a group of one or more matrix code readers previously paired with the electronic device.
[005] In one or more implementations, the electronic device identifies that the matrix code will be transmitted based on the fact that it will generate the matrix code and thus becomes aware that it will be transmitted. In several other implementations, the electronic device identifies that the matrix code will be transmitted based on image analysis of the content it is transmitting to a display device. In still other implementations, the electronic device identifies that the matrix code will be transmitted based on metadata included in the content it is transmitting to a display device.
[006] In various embodiments, the electronic device evaluates one or more conditions in one or more filtering lists to determine whether or not to signal one or more matrix readers based on imminent transmission of the matrix code. Filter lists include conditions under which signals must and/or must not be transmitted if a matrix code is identified. These conditions include one or more of time periods, characteristics of the matrix code, characteristics of the matrix code reader, characteristics of the content that the electronic device is configured to transmit to a display device, characteristics of the metadata included in the content that the electronic device is configured to transmit to a display device and so on. Furthermore, in various embodiments, a matrix code reader that has received a signal from the electronic device regarding the impending transmission of a matrix code evaluates the one or more conditions of one or more filter lists to determine whether or not to perform the ones. or more instructed actions.
[007] In addition, in some implementations, a matrix code reader transmits a confirmation message to the electronic device when it captures a matrix code after receiving a signal associated with it. The confirmation message attests that the array code was successfully captured.
[008] It should be borne in mind that both the foregoing general description and the detailed description below are given by way of example and explanation, not necessarily limiting the present invention. The attached drawings, which are incorporated into and form part of this report, illustrate the inventive subject. Together, the descriptions and drawings serve the function of explaining the principles of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following description includes exemplary computer systems, methods, and programs that incorporate various elements of the present invention. However, it should be borne in mind that the described invention may be practiced in various ways in addition to those described herein.
[0013] Electronic devices (such as signal decoders, television receivers, digital video recorders, digital video disc players, televisions, desktop computers, home appliances, and so on) may display matrix codes, such as QR codes, to various purposes. These include, but are not limited to, connecting users to information, providing content associated with an aspect of the electronic device, facilitating the ordering of products or services, helping users operate the electronic device, and so on. To make use of the matrix codes displayed by an electronic device, the user captures the matrix code using a matrix code reader device. For example, the user photographs the matrix code using the cell phone camera. The mobile phone includes an application that decodes the captured matrix code information and performs one or more actions based on that information (such as displaying the decoded information, connecting to a website, transmitting the decoded information to another device, and so on) , an application that transmits the captured matrix code to another device to decode and perform actions, and so on.
[0014] However, the role of the electronic device in capturing a displayed matrix code is essentially passive. The electronic device merely displays the matrix code for a period of time, perhaps with a time warning displayed beforehand that the matrix code is about to be displayed. If, after noticing that matrix code is being displayed (or is about to be displayed), the user cannot find the matrix code reader and use it to capture the matrix code in time, he loses the associated functionality to the matrix code in question. Therefore, the user is in charge of capturing the matrix code before the electronic device ceases to display it, not the electronic device. Even though the user needs help locating his matrix code reader, getting him ready to capture the matrix code, and actually using it to capture the matrix code, the device is unable to provide such help.
[0015] The present invention discloses systems and methods to assist in capturing matrix codes by signaling to matrix code readers. An electronic device identifies that it will transmit a matrix code to a display device. The electronic device identifies the matrix code based on the fact that it will generate the matrix code, based on image analysis of the content it is streaming to the display device, based on the metadata included in the content, and so on. Based on the identified matrix code that will be transmitted, the electronic device determines whether to transmit a signal to one or more matrix code reading devices (this determination may be based on the evaluation of one or more conditions in one or more filtering lists ).
[0016] The electronic device transmits the signal for a certain period of time before transmitting the matrix code to the display device, such as ten seconds, one minute and so on. The electronic device can transmit the matrix signal using several different wired and/or wireless communication links (such as a communication link via Bluetooth®, a communication link via WiFi and so on.). The electronic device transmits the signal to any matrix code reader within a communication range of the communication link used for transmission, only to a group of one or more matrix code readers previously paired with the electronic device or some other way.
[0017] As soon as received, the signal instructs the one or more matrix code readers to perform one or more actions associated with capturing the matrix code such as issuing an alert, starting an optical reader device, opening a code capture application of matrix and so on. The instructed array code reader evaluates one or more conditions in one or more filter lists to determine whether or not to perform the one or more instructed actions. In some implementations, when one of the matrix code readers captures the matrix code, the respective matrix code reader transmits an acknowledgment message to the electronic device stating that the matrix code was successfully captured.
[0018] Figure 1 is a block diagram illustrating a system 100 to help capture matrix codes by signaling matrix code readers. System 100 includes an electronic device 101, one or more display devices 102, and one or more matrix code reader devices 103. The electronic device may be any electronic device, such as a signal decoder, a television receiver, a a digital video recorder, a digital video disc player, a television, a desktop computer, an appliance, and so on. The display device can be any type of display device, such as a cathode ray tube screen television, a liquid crystal display television, a plasma screen television, a computer monitor, and so on. The matrix code reader device can be any type of matrix code reader device, such as a cell phone or mobile computing device that includes a camera, a bar code reader, and so on.
[0019] The electronic device 101 may include one or more processing units 104, one or more non-transient storage media 105 (which may take the form, inter alia, of a magnetic storage medium, an optical storage medium, a magneto-optical storage medium, a read-only memory, a random access memory, an erasable programmable memory, a flash memory, and so on), one or more output components 106, and one or more communication components 107. The processing unit executes instructions stored on the non-transient storage medium to transmit data to the display device 102 by the output component 106. For example, the electronic device may be a signal decoder and the display device a television, and the set-top box can receive content (such as television programming, pay-per-view videos, and so on) from a content provider (such as a content provider. cable television, a satellite television provider, a pay-per-view video provider and so on) by the communication component 107 and transmit the received content to the television by the output component 106. The data that the processing unit transmits to the display device by the output component may include one or more matrix codes (such as one or more QR codes). These matrix codes may be transmitted to the display device for purposes including, but not limited to, connecting users to information, providing content associated with an aspect of the electronic device, facilitating the ordering of products or services, helping users operate the electronic device. and so on.
[0020] The matrix code reader device 103 may include one or more processing units 108, one or more optical detectors 109 (such as a still image camera, a video camera, a barcode reader and so on. ), one or more non-transient storage media 110 (which may take the form, inter alia, of a magnetic storage media, an optical storage media, a magneto-optical storage media, a read-only memory, a random access memory, an erasable programmable memory, a flash memory, and so on) and one or more communication components 111. The processing unit 108 executes instructions stored on the non-transient storage medium 110 to capture one or more codes from array displayed on the display device 102. The processing unit also executes instructions stored on the non-transient storage medium to decode the information of a matrix code captured and perform one or more actions based on this information (such as displaying the decoded information, connecting to a website, transmitting the decoded information to another device, and so on), to transmit the captured matrix code to another device to decode and perform actions and so on.
[0021] To help a user capture matrix codes displayed on the display device 102, the electronic device 101 identifies that it will transmit a matrix code to the display device, determines signaling to one or more matrix code reader devices 103 with based on that identification and transmits one or more signals to the one or more matrix code reader devices (by communication components 107 and 111) which instruct them to perform one or more actions associated with capturing the matrix code. The one or more actions include operations such as issuing an alert associated with capturing the matrix code (such as a bell, bell, light, vibration, and so on), initiating and/or otherwise preparing the optical detector 109 to capture the matrix code, opening a matrix code software application, and so on. Therefore, the user using a matrix code reader device that received the signal is better prepared to capture the matrix code, increasing his chance of accessing the functionality associated with it.
[0022] The electronic device 101 identifies that it will transmit a matrix code to the display device 102 and transmits a signal associated with a matrix code reader device 103 for a certain period of time (such as twenty seconds, one minute and so on) before transmitting the matrix code to the display device. As the signal can be transmitted before the display of the matrix code by the electronic device, the user who uses the matrix code reader device to capture the matrix code will have more time to capture it. However, in various implementations, the electronic device can transmit the signal related to the matrix code reader device at the same time (or at nearly the same time, such as five milliseconds after the matrix code is transmitted, but within the time period in that the matrix code is displayed by the display device) which transmits the matrix code to the display device, after transmitting the code to the display device, and so on.
[0023] The matrix code that will be transmitted from the electronic device 101 to the display device 102 can be identified by the electronic device 101 in several different ways. In some implementations, the electronic device generates the matrix code which it then transmits to the display device. In these implementations, the electronic device becomes aware that it will transmit the matrix code because it generated the matrix code and is able to identify that it will transmit this without further processing. In other implementations, the matrix code is included in the content that the electronic device transmits to the display device (such as content coming from the content provider 112) and the electronic device identifies that it will transmit the matrix code when processing the content to identify codes of matrix contained in it. In still other implementations, the matrix code is described in the metadata included in the content that the electronic device transmits to the device and the electronic device identifies that the matrix code will be transmitted by analyzing this metadata. In these implementations, the metadata may indicate that the matrix code will be transmitted after a period of time and thus the electronic device is able to transmit the signal to the matrix code reader device 103 a certain period of time before the transmission of the code. matrix based on the indicated time interval. For example, the metadata may indicate that in five minutes a matrix code will be transmitted and, based on this information, the electronic device transmits the signal to the matrix code reader one minute before the matrix code is transmitted (or four minutes after receiving the metadata).
[0024] The communication link that the electronic device 101 uses to transmit signals to the one or more matrix code reader devices by the communication components 107 and 111 can be one or more of several wired and/or wireless communication links many different. In various implementations, the communication links can be a communication link via Bluetooth®, a communication link via WiFi, a communication link via radio, an infrared communication link, a communication link via cellular, a communication link via telephone, a communication link via wireless LAN, and so on.
[0025] In some implementations, the electronic device 101 transmits a signal to a single matrix code reader device 103 based on the identification of a matrix code that will be transmitted to the display device 102. However, in other implementations, the electronic device transmits the signal to several different matrix code reading devices. For example, after the electronic device identifies that a matrix code is to be transmitted, it transmits a signal to all matrix code reading devices that are within communication range of the communication link to send the signal (such as within the maximum Bluetooth® radius if a Bluetooth® communication link is used to send the signal). In another example, the electronic device transmits the signal to a series of matrix code reader devices included in a list of matrix code readers on the non-transient storage medium 105. This list of matrix code readers can be created and updated by pairing matrix code reading devices with the electronic device, adding and/or removing matrix code reading devices from the matrix code reader list as identified by user input, receiving matrix code reading devices from another device to add and/or remove from the matrix code readers list and so on.
[0026] Furthermore, after identifying that a matrix code will be transmitted, the electronic device 101 evaluates one or more conditions contained in one or more lists of filtering conditions stored in the non-transient storage medium 105 before transmitting a signal. to one or more matrix code reader devices 103. If none of the conditions in the list of filtering conditions are satisfied, the electronic device determines transmission of the signal. However, if any of the conditions in the list of filtering conditions are satisfied, the electronic device determines that the signal will not be transmitted. Filter condition lists can include conditions in which signals must not be transmitted even though a matrix code is identified. These conditions may include one or more (including combinations thereof) among time periods, characteristics of the matrix code, characteristics of the matrix code reader, characteristics of the content that the electronic device is configured to transmit to the display device 102, characteristics of the metadata included in the content that the electronic device is configured to transmit to the display device, and so on.
[0027] In a first example, the list of filtering conditions specifies not to transmit any signal referring to matrix codes identified between six and seven at night because the user specified in the user's preferences that he does not want to be disturbed to capture matrix codes during that period. The user may not wish to be disturbed during this period as this corresponds to the broadcast of his favorite television program. Therefore, if the electronic device 101 identifies that a matrix code will be transmitted between six and seven in the evening, it analyzes the filter list, judges that a condition has been satisfied, and therefore does not transmit the signal.
[0028] In a second example, the filtering conditions list specifies not to transmit any signal referring to identified matrix codes that access information with a content rating above a parental control setting stored on the non-transient storage medium 105. Therefore, if the electronic device 101 identifies that a matrix code that accesses adult content will be transmitted and the parental control setting is set to block adult content, the electronic device analyzes the list of filtering conditions, evaluates that a condition has been satisfied and therefore does not transmit the signal.
In a third example, the list of filtering conditions specifies that no signal is transmitted on weekdays to a specific matrix code reader device 103 listed in the matrix code reader list mentioned above. In this example, the matrix code reader list includes the specific matrix code reader device and a second matrix code reader device. Therefore, if the electronic device 101 identifies that a matrix code will be transmitted on a weekday, it analyzes the list of filtering conditions, identifies that a condition has been satisfied, and therefore transmits the signal to the second code reader device. matrix, but not to the specific matrix code reader device.
[0030] In a fourth example, the list of filtering conditions specifies that no signal referring to car advertisements is transmitted during the display of football matches. Therefore, if the electronic device 101 identifies that a matrix code associated with an automobile advertisement will be broadcast during a football match, the electronic device analyzes the list of filtering conditions, identifies that a condition has been satisfied and therefore does not transmit the sign. The electronic device can identify that the matrix code refers to an automobile advertisement by analyzing the matrix code, the metadata included in the content that is configured to transmit to the display device 102, and so on. The electronic device can identify which matrix code will be transmitted during a football match by analyzing the content that is configured to transmit to the display device, the metadata included in the content, and so on.
[0031] Furthermore, in some implementations, after a matrix code reader device 103 receives a signal referring to a matrix code that will be transmitted, it evaluates one or more conditions contained in one or more lists of filtering conditions stored in the medium. non-transient storage 110 before performing an action specified by the signal. If none of the conditions in the list of filtering conditions are satisfied, the array code reader device determines to perform the specified action. However, if any of the conditions in the filtering list are satisfied, the electronic device does not take the specified action. Filtering condition lists can include conditions under which the specified actions must not be performed even though signals are received. These conditions may include one or more (including combinations thereof) among time periods, characteristics of the matrix code, characteristics of the matrix code reader device, characteristics of the electronic device, content that the electronic device is configured to transmit to the display device 102, characteristics of the metadata included in the content that the electronic device is configured to transmit to the display device, and so on. For example, the list of filtering conditions can include a condition that commands that no action be taken on any signals other than those transmitted by a specific electronic device. When the matrix code reader device receives a signal that is not transmitted by the specific electronic device, it will not perform the actions specified by the signal. However, when the matrix code reader device receives a signal transmitted by the specific electronic device, it will perform the actions specified by the signal.
[0032] It should be kept in mind that the operation of the filter lists described above was given by way of example and is not intended to be limiting. For example, within the scope of the present invention, it is possible to use lists of conditions that require one or more conditions to be satisfied before signals associated with the transmission of a matrix code are transmitted and/or actions specified by those signals are performed on instead of conditions to be eliminated before they occur. Thus, the exclusionary type lists described above exemplify a possible scheme, but other configurations are also contemplated.
[0033] In some implementations, after the matrix code reader device 103 captures the matrix code referring to the signal transmitted by the electronic device 101, it transmits a confirmation signal to the electronic device by the communication components 107 and 111. The reader device of matrix code transmits the confirmation signal to the electronic device using the same communication link that it used to transmit the signal referring to the matrix code, using a different communication link than the one used to transmit the signal referring to the matrix code and so on.
[0034] Figure 2 illustrates a method 200 to help capture matrix codes by signaling matrix code readers. Method 200 can be performed by electronic device 101 of Figure 1. Flow begins at block 201 and follows block 202, where electronic device 101 operates. Thereafter, the flow proceeds to block 203, where the processing unit 104 determines whether or not to update the list of array code readers on the non-transient storage medium 105. If so, the flow proceeds to block 213. Do Otherwise, the flow follows block 204.
[0035] In block 204, after the processing unit 104 determines not to update the list of matrix code readers stored in the non-transient storage medium 105, the processing unit determines whether or not there is a matrix code that the electronic device 101 will transmit to display device 102 to be displayed by it. If not, flow returns to block 202, where the electronic device continues to operate. Otherwise, the flow goes to block 205.
[0036] In block 205, after the processing unit 404 determines that there is a matrix code that the electronic device 101 will transmit to the display device 102, the processing unit evaluates a filter list on the non-transient storage medium 105. Then the flow proceeds to block 206, where the processing unit determines whether any condition in the filter list has been satisfied or not. If so, flow returns to block 202, where the electronic device continues to operate. Otherwise, the flow goes to block 207.
[0037] In block 207, after the processing unit 104 determines that no condition in the filter list has been satisfied, the processing unit determines whether to broadcast (or multicast) a signal referring to the matrix code to all devices matrix code readers 103 within the radius of the communication link used by the communication component 107 or transmit the signal only to matrix code readers in a list of matrix code readers stored on the non-transient storage medium 105. processing unit determines the signal diffusion, the stream goes to block 212. Otherwise, it goes to block 208.
[0038] In block 208, after the processing unit 104 determines the transmission of the signal referring to the matrix code only to matrix code readers 103 in a list of matrix code readers, the processing unit transmits the signal to the readers of matrix code in the matrix code readers list using the communication component 107. Then, the stream proceeds to block 209. Separated from the stream between blocks 207, 208 and 209, the electronic device 101 transmits the matrix code to the display device by the output component 106. The matrix code can be transmitted before block 208, along with this block or after this block.
[0039] In block 209, after the processing unit 104 transmits the signal, it determines whether or not to wait for a response from the matrix code readers 103 to which the signal has been transmitted. If not, flow returns to block 202, where the electronic device continues to operate. Otherwise, the flow follows block 210.
[0040] In block 210, after the processing unit 104 determines to wait for a response from the matrix code readers 103 to which the signal has been transmitted, it waits for the response. Then the flow goes to block 211. In block 211, the processing unit determines whether or not the response has been received by the communication component 107. If so, the flow returns to block 202, where the electronic device continues operating. Otherwise, the flow returns to block 210, where the processing unit continues to wait for the response. It is understood that while method 200 has been illustrated and described so that electronic device 101 waits for the response to transmitted signals before sending signals relating to new matrix codes that will be displayed, other configurations are possible and contemplated. For example, the processing unit may perform a listening process that waits for the response and, at the same time, another process that identifies new matrix codes that will be transmitted and signals to one or more matrix 103 code readers about these new matrix codes. headquarters.
[0041] In block 212, after the processing unit 104 determines the broadcast (or multicast transmission) of the signal to all matrix code reader devices 103 within the radius of the communication link, the processing unit broadcasts the signal to the matrix code readers within the radius of the communication link using the communication component 107. The flow then proceeds to block 209. Separated from the flow between blocks 207, 212 and 209, the electronic device 101 transmits the code of matrix to the display device by output component 106. The matrix code can be transmitted before block 212, along with this block 212 or after this block 212.
[0042] In block 213, after the processing unit 104 determines to update the list of matrix code readers, it updates the list of matrix code readers. Updating the matrix code reader list may include pairing one or more matrix code reading devices 103 with the electronic device 101, unpairing one or more matrix code reading devices previously paired with the electronic device, adding one or more matrix code reader devices to the matrix code reader list based on information received about the one or more matrix code reader devices, remove one or more matrix code reader devices from the matrix code reader list with based on information received about the one or more array code reader devices, and so on. The flow then proceeds to block 204, where the processing unit determines whether or not there is a matrix code that the electronic device 101 will transmit to the display device 102 for display by the latter.
[0043] Figures 3A to 3G illustrate an exemplary 300A to 300G system that helps a 305A to 305G user to capture a matrix code displayed on a 302A to 302G television. This system may be that of Figure 1. As shown in Figure 3A, the user 305A is watching television programming that a set-top box 301A sends to a television 302A for display on a 303A television screen. As also illustrated, the user has a 304A smartphone, which he can use to capture one or more matrix codes displayed on the television screen.
[0044] In the exemplary system 300A illustrated in Figure 3A, the smartphone 304A was not previously paired with the signal decoder 301A. However, the user 305A can use selection elements associated with the set-top box or smartphone to initiate a process to pair Bluetooth® communication components of the smartphone with the set-top box (as shown in Figure 3B). As part of the pairing, the decoder 301B adds the smartphone 304B to a list of matrix code reader devices.
[0045] Thereafter, the decoder 301B identifies that it will transmit a matrix code to the television 302B in two minutes based on the analysis of the metadata included in the television programming, which describes the matrix code. Based on the identification, the decoder determines signaling to all devices in the matrix code device list (which includes smartphone 304B) about the matrix code one minute before the time the matrix code will be transmitted.
[0046] As illustrated in Figure 3C, the signal instructs the smartphone 304C to light an indicator light 307C to notify the user that a matrix code will be displayed. In addition, as illustrated in Figure 3D, the signal also instructs the 304D smartphone to then open a matrix code capture app (displayed on the 306D smartphone screen).
[0047] After that, as illustrated in Figure 3E, the signal decoder 301E transmits the matrix code to the television 302E, which, in turn, displays it on the screen 303E. As Figure 3F illustrates, the 305F user then uses the 304F smartphone to capture the matrix code. Furthermore, as illustrated in Figure 3G, the 304G smartphone transmits a confirmation message to the 301G beacon decoder which indicates that the matrix code has been successfully captured. In response to receipt of the confirmation message, the decoder transmits a confirmation indication to the 302G television, which the television displays on the 303G screen.
