It should also be understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise.

The first embodiment is as follows:

fig. 1 shows a system structure diagram of a recording and broadcasting system according to an embodiment of the present invention, where the recording and broadcasting system includes at least two cameras 10 (only two are shown in fig. 1), bluetooth beacons 11 (3 bluetooth beacons are taken as an example in fig. 1), an infrared microphone 12, a digital infrared host 13, and a recording and broadcasting host 14. Fig. 1 is an exemplary illustration only, and does not limit the number of bluetooth beacons 11 and cameras 10.

And the camera 10 is used for shooting the target space to obtain a video corresponding to the target space.

The target space may be a space corresponding to a classroom, or a space corresponding to a conference room or a building. In the embodiment of the present application, an application scenario of the recording and playing system is described by taking a classroom as an example, and in an actual situation, the application scenario may also be applied to other scenarios, which are not limited herein.

Optionally, due to the limitation of the installation position and the shooting angle of the camera, when a single fixed camera is used for shooting recorded and broadcast videos, the whole space is difficult to cover, and a certain shooting blind area exists, so that the shooting effect of the recorded and broadcast videos is poor. Therefore, in order to obtain a video with a larger field of view, at least two cameras are provided in the embodiment of the present application, and the shooting ranges of the cameras are not completely the same. For example, if the application scene of the recording and broadcasting system is in a classroom, at least two cameras 10 are installed in the classroom to photograph the room. Because the shooting ranges of the installed cameras 10 are different, when a user is in the shooting ranges of the cameras 10, the video shot by the corresponding camera 10 can be obtained, and the recording effect and quality of recorded and broadcasted video are improved.

Optionally, since the recording and broadcasting system of the embodiment of the present application includes at least two cameras 10, when the cameras 10 in the target space are set, a corresponding unique identifier is set for each camera 10 to distinguish different cameras 10, and a correspondence between the identifier of the camera 10 and a divided region (a plurality of regions divided in the target space) is established according to the identifier of the camera 10, so that the corresponding camera 10 can be determined according to the identifier of the camera 10, thereby obtaining a video collected by the corresponding camera 10. The identification of the camera 10 may be set by the user, for example, the classroom number is the comprehensive building 301, the unique identification of the camera 10 is set according to the number of the camera 10 and the number of the classroom, the unique identification of the camera 10 is set as the comprehensive building 30101 in combination with the number 01 of the camera 10, or the position of the camera 10 is set as the left side of the comprehensive building 301, and the like, which is not limited herein.

Alternatively, if there are only two cameras 10, in order to reduce the dead angle of shooting of the cameras 10 and improve the effect and quality of recorded and broadcast video, the shooting directions of the two cameras 10 in the target space are set to be opposite. For example, as shown in fig. 2, assuming that the shooting space of the recording and broadcasting system is in a classroom, the cameras 10 installed in front of and behind the classroom are assumed to be a first camera and a second camera that shoot in opposite shooting directions. If there are at least 3 cameras 10, there are at least 1 pair of cameras 10 with opposite shooting directions, for example, when there are 3 cameras 10, a pair of cameras 10 with opposite shooting directions may be provided, and when there are 4 cameras 10, two pairs of cameras 10 with opposite shooting directions may be provided with 4 cameras 10, or only one pair of cameras 10 with opposite shooting directions may be provided, and the other two cameras 10 are set according to the user's needs, which is not limited specifically here.

Optionally, in order to improve the effect and quality of the recorded and broadcast video, the recorded and broadcast system includes at least 3 cameras 10, wherein one camera may be separately arranged to shoot the device recording the teaching content, such as the blackboard or the electronic teaching screen, to obtain the teaching content video, that is, the camera 10 is fixed to shoot the device recording the teaching content, and is not used as a camera for shooting the user, and the other two cameras 10 are arranged in opposite shooting directions to shoot.

Optionally, since the cost of shooting with the tracking camera is high, a single fixed camera is usually installed in a target space (such as a classroom) to shoot, and the shooting range of the fixed camera is fixed, that is, tracking cannot be performed, therefore, under the condition that the fund is limited or the fixed camera is already installed indoors, the number of the fixed cameras can be increased, for example, at least 2 cameras 10 are included indoors and the shooting ranges are different, and then the recording and playing system provided by the present application is used to obtain the video of the real-time position of the user, so that the shooting effect which is the same as that of the tracking camera is originally achieved with a low modification, that is, a good recording and playing effect is achieved.

In the embodiment of the application, at least two cameras 10 are installed in the recording and broadcasting system to shoot different regions of a target space, so that the shooting blind areas of the cameras are reduced, thereby being beneficial to shooting according to the real-time position of a user, improving the quality and effect of recorded and broadcasted videos, setting corresponding identifiers for the cameras, establishing the corresponding relationship between the identifiers of the cameras and the divided regions of the corresponding cameras, determining the real-time position of the user (namely determining the divided regions corresponding to the real-time position of the user), determining the corresponding cameras according to the identifiers of the cameras, and acquiring the videos collected by the corresponding cameras.

And the Bluetooth Beacon 11 is used for broadcasting Beacon signals at set time intervals.

Optionally, since the bluetooth Beacon 11 is a battery-powered bluetooth low energy device, the cost is low, and it is not necessary to change a power supply device, a power supply line, and the like, therefore, the cost can be effectively saved by using the bluetooth Beacon 11 to transmit a Beacon signal that can be recognized by other devices (e.g., bluetooth devices).

Specifically, when the Beacon signal is transmitted using the bluetooth Beacon 11, the Beacon signal is broadcast at a set time interval, which may be set by a user. Since the position of the infrared microphone 12 is determined according to the signal strength value of the Beacon signal acquired by the infrared microphone 12, and the position of the user holding the infrared microphone 12 may change in real time, when the time interval for broadcasting the Beacon signal is set, the time interval is usually set within a threshold value (e.g., 1 s), for example, the set time interval is 0.1s, so that the acquired position of the infrared microphone 12 (i.e., the position of the user) is the real-time position of the user.

Alternatively, when the bluetooth Beacon 11 is set up, a planar coordinate system or a spatial coordinate system is constructed in a classroom, for example, with the position of a certain wall corner in a room as a coordinate origin and 20 centimeters as a unit on a coordinate axis, a coordinate system is established, such as a position which is 1 meter apart from the origin on an x-axis and has coordinates of (5,0) so that each position in the room has a common coordinate reference, and specific position information of the set bluetooth Beacon 11 is determined, so that the position of the infrared microphone 12 which receives the Beacon signal of the bluetooth Beacon 11 can be determined with respect to the bluetooth Beacon 11 based on the specific position information of the bluetooth Beacon 11, thereby determining the position information of the infrared microphone in the room,

in the embodiment of the application, the Beacon signal is broadcasted by the Bluetooth Beacon 11 with low power consumption and battery power supply, so that the practical application is facilitated, and the cost of the practical application is reduced.

The infrared microphone 12 is used for acquiring the Beacon signal and determining the signal intensity value of the newly acquired Beacon signal; the infrared microphone 12 is further configured to send an infrared signal to the digital infrared host 13, where the infrared signal includes the signal intensity value.

Specifically, the infrared microphone 12 receives the Beacon signal sent by the bluetooth Beacon 11, analyzes the newly received Beacon signal, determines a signal intensity value of the Beacon signal, and sends an infrared signal including the signal intensity value to the digital infrared host 13.

Optionally, the infrared microphone 12 is provided with a bluetooth module and an infrared module, so as to receive the Beacon signal sent by the bluetooth Beacon 11 through the bluetooth module, and send an infrared signal containing the signal intensity value to the digital infrared host 13 through the infrared module.

In the embodiment of the present application, because the user teaches with a handheld microphone in the course of giving lessons, the real-time position of the infrared microphone 12 is the current real-time position of the user, therefore, the infrared microphone 12 provided with the bluetooth module and the infrared module receives the Beacon signal sent by the bluetooth Beacon 11, and send the signal intensity value of the Beacon signal to the digital infrared host 13 through the infrared signal, so that the digital infrared host 13 determines the real-time position of the infrared microphone 12 according to the signal intensity value, that is, the real-time position of the user is obtained, meanwhile, the infrared module of the infrared microphone 12 sends the infrared signal containing the signal intensity value, which is simple and convenient, does not need complex wiring, and is convenient for the indoor improvement of the recording and broadcasting system.

A digital infrared host 13 for receiving the infrared signal, analyzing the signal intensity value from the infrared signal, and calculating the real-time position of the infrared microphone 12 based on the signal intensity value; the digital infrared host 13 is further configured to determine an identifier of a camera corresponding to the real-time position of the infrared microphone, and send the identifier of the camera to the recording and broadcasting host, where when the identifier of the camera corresponds to the real-time position of the infrared microphone, the camera corresponding to the identifier of the camera can capture the real-time position of the infrared microphone.

Specifically, after receiving the infrared signal sent by the infrared microphone 12, the digital infrared host 13 analyzes the received infrared signal to obtain a signal intensity value of a Beacon signal included in the infrared signal, so as to calculate the real-time position of the infrared microphone 12 based on the signal intensity value.

Specifically, since the shooting ranges of the cameras are different, after the real-time position of the user is obtained, it is necessary to determine which shooting area of the camera 10 corresponds to the divided area where the real-time position is located according to the real-time position, and therefore, a preset corresponding relationship between the identifier of the camera 10 and the divided area is needed, so that after the real-time position of the infrared microphone 12 is determined, the identifier of the camera corresponding to the real-time position can be determined according to the divided area where the real-time position is located, and the identifier of the camera is sent to the recording and playing host 14, so as to obtain the video collected by the corresponding camera as the recorded and played video. When the identification of the camera 10 corresponds to the real-time position, that is, the real-time position is in the divided area of the camera 10 corresponding to the identification of the camera 10, the camera 10 can capture the real-time position of the infrared microphone 12.

Optionally, when setting the correspondence between the camera 10 and the divided regions, the size of the range of the divided regions is not uniquely defined, the shooting region of the camera may be used as the divided region, and the camera and the shooting region (divided region) are set to be in a one-to-one correspondence, or the classroom may be divided into a plurality of divided regions, and the correspondence between the camera and the divided region (which refers to a plurality of regions obtained by dividing the region in the classroom) is set to be one-to-many, that is, the region in the classroom is divided into a plurality of divided regions, and the shooting region of one camera may correspond to the plurality of divided regions, so that when the multiple cameras can shoot the same region, the region where the user is located is obtained as a camera with better shooting effect according to the correspondence between each camera and the divided region. For example, as shown in fig. 3, both the camera 1 and the camera 3 can capture the divided area 7 where the real-time position of the user is located, but since the divided area where the current position of the user is located is closer to the camera 1, the capturing effect is better, the divided area 7 is set to correspond to the camera 1, so that the video collected by the camera 1 corresponding to the divided area 7 is taken as the recorded and broadcast video by the subsequent recording and broadcasting host 14. In some embodiments, a camera instruction selected by a user may be received, and an identifier of a camera corresponding to the camera instruction is obtained, so that the recording and playing host 14 displays a video captured by the camera 10 indicated by the camera instruction. In some embodiments, in order to sufficiently display the captured video of the user, the identifiers of all the cameras corresponding to the divided area may also be obtained, so that the recording and broadcasting host 14 displays the video captured by the cameras.

The recording and broadcasting host 14 is configured to receive the identifier of the camera sent by the digital infrared host 13, and acquire a video acquired by the camera corresponding to the identifier of the camera.

Specifically, since the identifier of the camera sent by the digital infrared host 13 is the identifier of the camera in the divided area where the real-time position of the user is shot, the video shot by the user can be acquired according to the identifier of the camera, so that the video recording according to the real-time position of the user is realized at a low cost, the user is guaranteed to be shot by the recorded and broadcast video, and a good recorded and broadcast effect is achieved.

Optionally, each camera 10 of the recording and playing system may perform shooting simultaneously, and when the recording and playing host 14 needs to acquire the video acquired by the corresponding camera 10, the recording and playing host 14 switches the corresponding camera and displays the video shot by the switched camera, so as to improve the timeliness of the displayed video. Or a single camera (i.e. the currently required camera) may be set to work, and when the recording and broadcasting host 14 needs to acquire the video acquired by the corresponding camera, the corresponding camera is controlled to start working, so as to acquire the video acquired by the camera, thereby reducing unnecessary resource waste.

In the embodiment of the present application, since the recorded and broadcast video needs to be recorded according to the real-time position of the user, the recorded and broadcast host 14 receives the identifier of the camera sent by the digital infrared host 13 to obtain the video acquired by the camera corresponding to the identifier of the camera as the recorded and broadcast video, so that the user can be shot in real time in the recorded and broadcast process, and the recorded and broadcast effect is improved.

In the embodiment of the present application, different areas in a classroom are photographed by at least two cameras 10, after a bluetooth Beacon 11 with low power consumption broadcasts a Beacon signal at a set time interval, an infrared microphone 12 can receive the Beacon signal and determine a signal intensity value of the newly acquired Beacon signal, and a digital infrared host 13 transmits the infrared signal, so that the digital infrared host 13 calculates a latest position of the infrared microphone 12 according to the signal intensity value, because the infrared microphone 12 is usually held or worn by a user, the latest position of the infrared microphone 12 is also a real-time position of the user, therefore, an identifier of a camera corresponding to the real-time position is determined according to the real-time position, and a recorded broadcast host 14 transmits the identifier of the camera, so that the recorded broadcast host 14 acquires videos collected by the corresponding camera as recorded broadcast videos according to the identifier of the camera, and the recorded broadcast videos can be photographed to the real-time position by the camera corresponding to the identifier of the camera determined according to the real-time position, and shooting ranges of different cameras are different, therefore, the recorded videos collected by the recorded broadcast host can be displayed according to the recorded in a relatively low-time recorded broadcast system, and the recorded videos acquired by the real-time recorded broadcast system can be displayed simply and the recorded by the user, and the recorded broadcast system, thereby improving the real-time recording system.

In some embodiments, the number of the bluetooth beacons 11 is greater than 2, because the three-point positioning method can perform positioning more accurately.

In some embodiments, since the Beacon signal is relatively susceptible to the environment, so that there is a certain error when performing positioning according to the signal strength value thereof, for example, the error caused by path loss is larger the farther the propagation distance is, so as to further improve the positioning accuracy of the infrared microphone 12 (i.e., the user), at least 3 bluetooth beacons 11 are installed at the same target height, so as to simultaneously reduce the propagation distances of the multiple bluetooth beacons 11, thereby reducing the error. That is, in the embodiment of the present application, if the number of the bluetooth beacons 11 is greater than 3, at least 3 bluetooth beacons 11 are installed at the same target height, and the installation heights of other bluetooth beacons 11 are not limited, and may be installed at the same target height or at non-target heights. For example, the effect of propagating the Beacon signal of the bluetooth Beacon 11 at a height of 2 meters is better, so that 3 bluetooth beacons 11 can be installed at the target height, and 3 bluetooth beacons 11 can be installed at a height of 2 meters, and then the corresponding real-time position 1 and real-time position 2 are obtained by calculation according to the bluetooth Beacon at the target height and the Beacon signal of the bluetooth Beacon 11 installed at a height of 2 meters, respectively, and the average value is obtained according to the real-time position 1 and the real-time position 2, so as to improve the positioning accuracy.

In the embodiment of the application, because factors such as propagation distance can influence the signal strength value of Beacon signal for positioning accuracy descends, has great error, consequently, when installation bluetooth Beacon 11, makes 3 at least bluetooth Beacon 11 install on same target height, with the propagation distance who reduces the Beacon signal, thereby reduces the error of the signal strength value of Beacon signal, and then improves the degree of accuracy of user's location.

In some embodiments, when the requirement on the accuracy of the real-time position of the user is high, in order to improve the precision of user positioning, at least 4 bluetooth beacons 11 may be set, and at least 4 Beacon signals are selected as target Beacon signals, the target Beacon signals are combined by using 3 target Beacon signals as a group, the real-time position of the infrared microphone 12 is calculated based on each combination, an initial position corresponding to each combination is obtained, and an average value is calculated according to each coordinate value (plane coordinate or space coordinate) of each initial position, so as to determine the real-time position of the infrared microphone 12. For example, the infrared microphone 12 receives Beacon signals sent by 6 bluetooth beacons 11, selects 4 Beacon signals (a, b, c, d) with the maximum signal intensity value as target Beacon signals, combines the target Beacon signals to obtain combinations abc, abd, acd, bcd, and respectively obtains the combinations according to the targets of the combinationsCalculating the Beacon signal to obtain the initial position m of the infrared microphone 12 ₁ (x ₁ ,y ₁ ,z ₁ )、m ₂ (x ₂ ,y ₂ ,z ₂ )、m ₃ (x ₃ ,y ₃ ,z ₃ )、m ₄ (x ₄ ,y ₄ ,z ₄ ) Calculate m ₁ 、m ₂ 、m ₃ 、m ₄ If the average value of the x axis is x = (x 1+ x2+ x3+ x 4)/4, obtaining the coordinate (x, y, z) of the real-time position of the infrared microphone 12 according to the average value of the values of the coordinate axes, thereby determining the identifier of the corresponding camera according to the divided area where the coordinate is located, obtaining the video collected by the camera corresponding to the identifier, and obtaining the video picture of the user according to the coordinate.

In some embodiments, the target height may be set according to the average height of a user (e.g., a teacher) using the infrared microphone 12 in order to reduce the propagation distance of the Beacon signal, because the error caused by path loss and the like is larger as the propagation distance of the Beacon signal is farther, and the propagation distance of the Beacon signal depends on the distance between the bluetooth Beacon 11 and the infrared microphone 12. Optionally, the target height may also be set by the user according to the user's own requirements, for example, when the Beacon signal is installed at 2 meters, the propagation effect of the Beacon signal may be better, and then 2 meters may be set as the target height. Optionally, one or more target heights may be set, for example, since the height difference between the male user and the female user may be large, and the error of the average height is large, the average height of the male user and the average height of the female user may be used as the target height to obtain the target height 1 and the target height 2, and then at least 3 bluetooth beacons 11 exist on the target height 1 and the target height 2, that is, at least 6 bluetooth beacons 11 coexist in the classroom.

In some embodiments, the infrared microphone 12 is further configured to:

acquires the voice signal of the user and sends the infrared signal containing the voice signal to the digital infrared host 13.

Specifically, since the user gives a lecture through the infrared microphone, the infrared microphone can acquire a good voice signal of the user, and therefore, the voice signal of the user in the course of giving a lecture is acquired through the infrared microphone 12, and the infrared signal including the acquired voice signal is sent to the digital infrared host 13, so that the digital infrared host 13 can send the voice signal to the recorded broadcast host 14, and the voice signal at the corresponding time of the recorded broadcast video is output. Optionally, the infrared microphone 12 sends the infrared signal containing the voice signal in real time or at a set time interval (e.g., 0.2 s), and obtains a clear voice signal at a corresponding time in real time, so that a video captured by a user and obtained subsequently can obtain an audio with a good signal.

Optionally, when the infrared microphone 12 sends the infrared signal, the voice signal and the signal strength value of the Beacon signal obtained at the same time are sent to the digital infrared host 13 together, so as to obtain the real-time position and the real-time voice signal of the user at the same time, so that the video obtained according to the real-time position has good audio at the corresponding moment, and the quality of the recorded and played video is improved.

In the embodiment of the application, the infrared microphone 12 sends the infrared signal which also contains the voice signal of the user, so that the video acquired according to the real-time position has good audio frequency, and the quality of recorded and broadcast video is improved.

In some embodiments, the infrared microphone 12 is specifically configured to:

and if the Beacon signals of more than 3 bluetooth beacons 11 are received, determining the signal strength value of each Beacon signal.

Specifically, because the signal strength value error of the Beacon signal is affected by the propagation distance, when the Beacon signal transmitted by more than 3 bluetooth beacons 11 is received, the signal strength value of the Beacon signal corresponding to each received bluetooth Beacon 11 is determined, the installation position of the bluetooth Beacon 11 of the received Beacon signal is not considered, that is, whether the bluetooth Beacon 11 is at the same target height or not is not considered, 3 Beacon signals with the maximum signal strength value are selected as target Beacon signals, and the infrared signals including the signal strength value of the target Beacon signals are transmitted to the digital infrared host 13, so that the digital infrared host 13 determines the real-time position of the user according to the signal strength value of the target Beacon signals. For example, in a recording and broadcasting process in a certain classroom, the infrared microphone 12 receives Beacon signals of 5 bluetooth beacons 11 (such as A, B, C, D, E), analyzes the received 5 Beacon signals, and obtains signal strength values (a, b, c, d, e) corresponding to each bluetooth Beacon 11, where the maximum value of the signal strength values a, c, d indicates that the bluetooth Beacon A, C, D is closest to the current position (i.e., the real-time position) of the infrared microphone 12 (user) at this time, and then the Beacon signal sent by the bluetooth Beacon A, C, D is used as a target Beacon signal at this time, and an infrared signal including the signal strength values a, c, d of the target Beacon signal is sent to the digital infrared host 13, so that the digital infrared host 13 can determine the real-time position of the user according to the signal strength values of the target Beacon signal, and reduce an error caused by the propagation distance of the Beacon signal.

It should be noted that, when it is not considered whether the bluetooth beacons 11 are at the same target height, there is a case that the bluetooth beacons 11 are not at the same height, at this time, because the distances from the bluetooth beacons 11 at different heights to the same infrared microphone 12 on the same plane coordinate due to the height influence are not the same, the intersection point obtained by drawing a circle on the plane based on the position of the bluetooth beacon 11 and the corresponding distance is not accurate, at this time, the intersection point of the spherical surface is obtained by taking the distance between each bluetooth beacon 11 and the infrared microphone 12 as a radius based on the position of each bluetooth beacon 11 as a center of circle, so as to accurately obtain the real-time position of the infrared microphone 12.

In this application embodiment, because reasons such as Beacon signal propagation path loss for the error of the signal strength value of Beacon signal increases along with propagation distance's increase, consequently, when receiving the Beacon signal that is greater than 3 bluetooth Beacon 11 and sends, regard as target Beacon signal 3 Beacon signals that signal strength value is the biggest, with the signal strength value based on above-mentioned target Beacon signal confirms user's real-time position. In addition, the signal intensity value of the target Beacon signal is the maximum 3 of the received Beacon signals, so that the propagation distance of the target Beacon signal is the minimum, the error of the target Beacon signal is the minimum, and the accuracy of the real-time position of the user calculated according to the target Beacon signal is improved.

In some embodiments, in order to reduce the cost and the calculation amount of the recording and broadcasting system for calculating the real-time position of the user, and reduce the burden of the system, the recording and broadcasting system sets 3 bluetooth beacons 11 installed at the same target height, at this time, the calculation of the height is not considered in the process of calculating the real-time position of the user, the position information of each bluetooth beacon 11 is determined according to the constructed horizontal coordinate system, and the target distance between each bluetooth beacon 11 and the infrared microphone 12 is calculated according to the signal intensity value of each bluetooth beacon 11, so that the position information of the infrared microphone 12 is calculated according to the position information of each bluetooth beacon 11 and the corresponding target distance, and the identification of the corresponding camera is determined according to the divided area where the infrared microphone 12 is located, which is indicated by the position information, so as to obtain the real-time video collected by the corresponding camera.

Corresponding to the recording and broadcasting system, fig. 4 shows a work flow diagram of a recording and broadcasting system, as shown in fig. 4, a bluetooth Beacon 11 broadcasts and transmits a Beacon signal, a bluetooth module of an infrared microphone 12 receives the Beacon signal transmitted by the bluetooth Beacon 11 and acquires a signal intensity value thereof, and acquires a voice signal of a user through the infrared microphone 12, and transmits an infrared signal including the signal intensity value and the voice signal to a digital infrared host 13 through an infrared module of the infrared microphone, and the digital infrared host 13 calculates a real-time position of the infrared microphone 12 based on the received infrared signal, that is, calculates the real-time position of the user. According to the preset corresponding relationship between the camera and the divided area, the identifier of the camera corresponding to the position of the infrared microphone 12 is determined, and the identifier of the camera is sent to the recording and broadcasting host 14, and the recording and broadcasting host 14 obtains the video acquired by the camera corresponding to the identifier of the camera according to the received identifier of the camera.

The following describes the steps of the recording and playing method shown in fig. 5:

step S501, receiving an infrared signal sent by the infrared microphone 12 of the recording and broadcasting system, where the infrared signal includes a signal intensity value of the Beacon signal received by the infrared microphone 12.

Specifically, the digital infrared host 13 is provided with a digital infrared receiver, and receives an infrared signal sent by an infrared microphone 12 in the recording and broadcasting system through the digital infrared receiver, where the infrared signal includes a signal strength value of a Beacon signal received by the infrared microphone 12.

Specifically, since the infrared signal includes a signal strength value of the Beacon signal received by the infrared microphone 12, the received infrared signal is analyzed to obtain the signal strength value of the Beacon signal, and a distance between the corresponding bluetooth Beacon 11 and the infrared microphone 12 receiving the Beacon signal sent by the bluetooth Beacon 11 is calculated according to the signal strength value, so as to calculate a real-time position of the infrared microphone 12 according to the distance, and determine an identifier of a camera corresponding to the real-time position according to a preset corresponding relationship between the camera and a divided area.

Optionally, if the number of the bluetooth beacons 11 in the recording and broadcasting system is greater than 2, when the real-time position of the infrared microphone 12 is calculated based on the infrared signal, the signal strength values (r 1, r2, r 3) of Beacon signals of 3 bluetooth beacons 11 are obtained, and the distance between the corresponding bluetooth Beacon 11 and the infrared microphone 12 is calculated according to the signal strength values, so as to determine the real-time position of the infrared microphone 12 according to the distance. For example, the signal strength values R1, R2, and R3 of the bluetooth beacons 11R1, R2, and R3 are acquired, and the distances between the bluetooth beacons 11R1, R2, and R3 and the infrared microphone 12 are calculated from the signal strength values R1, R2, and R3, respectively.

Step S504, sending the identifier of the camera to the recording and playing host 14, so that the recording and playing host 14 obtains the video collected by the camera corresponding to the identifier of the camera.

In this embodiment, the digital infrared host 13 receives the infrared signal sent by the infrared microphone 12, and calculates the real-time position of the infrared microphone 12 according to the signal strength value of the Beacon signal contained in the infrared signal, because the infrared microphone 12 is usually held or worn by the user, the real-time position of the infrared microphone 12 is the real-time position of the user, therefore, the identification of the camera corresponding to the real-time position is determined, and the identification of the camera is sent to the recording and broadcasting host 14, so that the recording and broadcasting host 14 obtains the video collected by the corresponding camera according to the identification, thereby realizing the real-time shooting of the user in the recording and broadcasting process, and further improving the recording and broadcasting effect.

the distance between each bluetooth beacon 11 and the infrared microphone 12 is calculated based on each signal strength value.

Optionally, the distance d between each bluetooth beacon 11 and the infrared microphone 12 calculated by the signal strength value is:

wherein abs is an absolute value, RSSI represents a signal strength value of the received Beacon signal, a represents a signal strength value when the bluetooth Beacon 11 is 1 meter away from the infrared microphone 12, and n is an environmental attenuation factor.

Optionally, the real-time position of the infrared microphone 12 is calculated according to the target distance between each bluetooth beacon 11 and the infrared microphone 12, 3 bluetooth beacons 11 may be selected as target bluetooth beacons 11 based on a three-point positioning method, a circle is drawn according to the target distance between the coordinate position of each target bluetooth beacon 11 and the infrared microphone 12 by taking each target bluetooth beacon 11 as a center of the circle and the corresponding target distance as a radius, and intersection coordinates of the three circles are obtained, so as to obtain the real-time position of the infrared microphone 12. Optionally, when selecting the target bluetooth Beacon 11, the bluetooth Beacon 11 installed at the same height may be selected as the target bluetooth Beacon 11 to reduce the amount of calculation in the height aspect, and the bluetooth Beacon 11 corresponding to the Beacon signal with the largest signal strength value may also be selected as the target bluetooth Beacon 11 to reduce the error of the signal strength value of the Beacon signal caused by the propagation distance, thereby improving the accuracy of real-time positioning.

It should be noted that, since the selected bluetooth beacons 11 are not necessarily installed at the same height, the coordinates of the intersection point of the sphere with the corresponding target distance as the radius and the center of each of the target bluetooth beacons 11 as the center of the circle are required to be used as the position coordinates of the infrared microphone 12 as the real-time position of the infrared microphone 12, so as to avoid errors caused by different heights.
