Referring to fig. 1, a flow diagram of one embodiment of an intelligent live method according to the present disclosure is shown. The execution main body of the intelligent live broadcasting method can be a control host in a live broadcasting Internet of things system, the live broadcasting Internet of things system further comprises a main controller and at least one auxiliary controller, and the control host is connected with the main controller and the auxiliary controller respectively.

As shown in fig. 1, the intelligent live broadcasting method includes the following steps:

and 101, receiving a switching instruction which is sent by the main controller and used for switching the current live video camera from the first video camera to the second video camera.

Here, the first camera is a currently live camera controlled by the main controller, and the second camera is a currently non-live camera controlled by any one of the at least one sub-controller.

In some embodiments, the live internet of things system may include at least two cameras, and the at least two cameras may be installed at suitable positions according to the scene that needs to be live. For example, taking a standard track and field and a football field as examples, installation positions of a plurality of cameras can be determined; as shown in fig. 2, eight mounting positions may be determined at four locations on the track and field and the soccer field; each mounting machine position can be provided with at least one camera, for example, a panoramic camera and/or a dome camera can be mounted at the first mounting machine position, while only one dome camera may be mounted at the second mounting machine position, and similarly, the third mounting machine position-the eighth mounting machine position can also select the mounted cameras according to actual conditions.

Of course, in the specific embodiment, in order to achieve better live broadcast effect, more installation positions can be arranged for an athletic field and a football field. That is, the specific installation position of the installation is not limited, and only the reasonable setting is needed according to the actual situation.

When the scene needing live broadcasting is a skiing sports scene, the top of a part of cable car supports can be determined as the installation position of the camera.

That is, in the embodiment of the present application, a live broadcast scene and a corresponding installation machine position are not limited, and only a reasonable installation machine position needs to be selected according to a live broadcast scene specifically required by a worker, and the type of a camera to be installed at the installation machine position can be determined according to the actual situation of each installation machine position. That is, the installation position and the number of the cameras can be reasonably set according to the actual scene needing live broadcasting, and only a plurality of cameras which are installed can collect all scenes needing live broadcasting.

In some embodiments, the control host may be used to control the switches of the installed cameras, as well as the shooting angles of the individual cameras. When a user needs to switch the cameras for shooting, a switching instruction can be generated through the main controller, and the control host can switch the cameras which are in live broadcasting according to the instruction of the switching instruction.

It should be noted that, in a specific application scenario, in order to reduce the recording amount of unrelated videos, during a live broadcast process, only some cameras are in a recorded state (live cameras), and some cameras are in a non-recorded state (non-live cameras). When the athlete is about to leave the shooting range of the live video camera, the main controller can be controlled to generate a switching instruction, and another non-live video camera is started according to the instruction of the switching instruction, so that continuous live broadcast of the sports event is realized.

In an embodiment, the sub-controller may control a shooting area of a non-live camera, for example, the sub-controller may align a second camera with an area to be shot, so that the main controller may not need to adjust a shooting direction of the second camera immediately after taking a control right of the second camera. That is, the shooting direction of the second camera has been previously adjusted by the sub-controller.

And 102, distributing the control authority of the sub-controller to the second camera to the main controller according to the switching command so that the main controller has the control authority to the second camera.

In some embodiments, after the master controller obtains the control authority of the second camera, the shooting direction of the second camera can be properly adjusted according to the movement direction of the athlete, and the master controller does not need to greatly adjust the shooting area of the second camera after obtaining the control authority of the second camera. Therefore, the phenomenon that the watching experience of a user is influenced due to the fact that the picture jumps greatly in the live broadcasting process can be avoided. That is, the lens switching can be coherent, and a better viewing experience can be presented to the user.

And 103, live broadcasting the live broadcasting picture acquired by the second camera.

In some embodiments, after the main controller obtains the control authority of the second camera, the live broadcast picture acquired by the second camera may be directly live broadcast, and the first camera may be turned off, and after the first camera is turned off, the sub-controller may control the first camera and may adjust the shooting area of the first camera.

In some embodiments, after the master controller obtains the control authority of the second camera, the first camera may not be turned off, such as: when two sports are required to be played directly (jumping and running), the first camera and the second camera may need to be in working states at the same time, that is, both the first camera and the second camera are live cameras and can be controlled by the main controller.

In some embodiments, after the main controller obtains the control authority of the second camera, the first camera may not be turned off, but the sub-controller may control the image capturing range of the first camera, and may upload and store the image captured by the first camera.

It can be seen that, in the embodiment of the present application, when the live video camera needs to be switched from the first video camera to the second video camera, the main controller may be controlled to generate a switching instruction, and the control host may control the second video camera to be the live video camera and distribute the control authority to the main controller; since the second camera is controlled by the sub-controller in advance, that is, before switching is performed, the user can adjust the shooting area of the second camera through the sub-controller. It can be seen that the user only needs to operate the main controller and the sub-controller, and does not need to arrange a worker for each camera, thereby reducing the manpower consumption.

In some embodiments, the number of at least one slave is less than or equal to the total number of cameras in the live internet system described above.

That is, one slave controller may control a plurality of non-live cameras, or one slave controller may control one non-live camera, and the specific control manner of the slave controller to the non-live cameras may be set according to the actual situation, where the number of the slave controller that may specifically control the non-live cameras is not limited.

In some embodiments, step 103 (live broadcasting the live broadcast picture captured by the second camera) may specifically include: and receiving a control instruction of the main controller to the second camera, adjusting the shooting direction of the second camera and/or the lens focal length of the second camera according to the instruction of the control instruction, and live broadcasting the live broadcast picture acquired by the adjusted second camera.

Here, the control command is used for controlling the second camera to rotate and/or instructing to adjust the focal length of the lens of the second camera.

In some embodiments, the control instructions are also used to control camera aperture size, focus mode, shooting orientation, and the like.

In some embodiments, after receiving the control authority of the second camera, the main controller may issue a control instruction to the second camera, and may adjust the rotation direction and the focal length of the second camera, thereby achieving a better live broadcast effect. Such as: in a football match, a certain player may be close-up after having made a goal (i.e. the focus may now be adjusted so that the goal appears in the live view as much as possible while the other players are no longer in the live view).

In some embodiments, the control command is generated by the main controller when detecting that a preset point button on the main controller is triggered.

In some embodiments, the main controller may preset a plurality of preset point buttons, and when one of the preset point buttons is clicked, the main controller may generate a control instruction, for example, click one of the preset point buttons for characterizing the focus adjustment; the focal length of the camera in live broadcasting can be adjusted to be small, and when a preset point button for representing the rotation direction is clicked, the shooting direction of the camera can be adjusted. Of course, the specific adjusting function of the plurality of preset point buttons and the specific number of the plurality of preset point buttons may be set according to practical situations, and are not limited herein.

In some embodiments, the preset point button for indicating the rotation direction may also be understood as a rotation handle, and the user may adjust the shooting direction of the live camera according to the rotation handle, for example, when the rotation handle is pulled downward, the shooting direction of the live camera may be moved downward, and when the rotation handle is pulled leftward, the shooting direction of the live camera may be moved leftward. That is, the moving direction of the camera which is live broadcasting can be determined by pulling the rotating direction, and the shooting direction of the camera which is live broadcasting can be easily adjusted by controlling the rotating handle.

In some embodiments, each camera is provided with a corresponding driving device, the driving device is used for driving the camera to perform direction adjustment, and since the driving device is driven by a motor, a phenomenon of picture shaking does not occur when the shooting direction of the camera is adjusted, whereas in the prior art, a shooting staff usually holds the camera for shooting, and therefore, a phenomenon of picture shaking often occurs.

In some embodiments, the sub-controller may also preset a plurality of preset point buttons for adjusting the non-live video camera, and the adjustment process and principle of the sub-controller for the non-live video camera may be the same as the adjustment process and principle of the main controller for adjusting the live video camera; for the sake of simplicity of the description, the adjustment process and principle of the sub-controller for the non-live video camera are not described in detail herein.

In some embodiments, the master controller may further include a toggle control, which when triggered, may generate a toggle instruction. That is, it can be understood that when the switching instruction is triggered, the camera currently being live and the camera not being live can be displayed on the display screen of the main controller, and the user can select the camera not being live, so as to generate the control instruction.

In some embodiments, the main controller may also automatically adjust the generation of control commands and adjust the capture of the second camera based on the scene captured by the camera. Such as: in the football match, main control unit can train a recognition model in advance, and the training sample of recognition model can be operator's characteristic and football characteristic, and after the training was accomplished, the recognition model can be according to the video frame image that the second camera transmitted back, confirms whether adjust the second camera. If the football is identified to be at the edge of the video frame image, a control instruction can be generated to adjust the shooting direction of the camera, and if the equipment is smaller than the football, a control instruction used for adjusting the focal length of the second camera can be generated. That is, the neural network model can be trained in advance, so that the main controller can automatically generate the control instruction according to the video frame image shot by the second camera.

In some embodiments, when the live view captured by the second camera includes at least two views of a scene, the method further comprises:

receiving pictures of at least two scenes collected by the second camera;

and extracting the picture of the target scene from the pictures of the at least two scenes, and carrying out live broadcast on the picture of the target scene.

In some embodiments, if the second camera is a panoramic camera, the video frames captured by the panoramic camera may be used to capture one of the video frames of a match to form a single-match rebroadcast video stream for each match performed on the same playing field as desired. Such as: the track and field sports field has sports items such as running, high jump, long jump, shot and the like to match simultaneously, pictures of the high jump or the running can be independently captured to respectively form rebroadcast videos of the high jump and the running, and the pictures of the high jump or the running which are independently captured can be understood as pictures of a target scene.

Therefore, the user is not influenced by other motions when watching the live broadcast of a certain motion in such a way, and the watching experience of the user is improved.

In some embodiments, the above method further comprises: receiving at least one comment content which is input into the live broadcast picture when at least one user watches the live broadcast picture; the start time and the end time of each narration content are recorded.

In some embodiments, a user can watch live broadcast through live broadcast software installed on a terminal device, that is, the control host can display a picture acquired by the live broadcast camera on the display screen, and can transmit the acquired picture to a corresponding cloud platform through a wireless network, and the user can acquire live broadcast data from the cloud platform through the live broadcast software, so that the live broadcast can be watched. Of course, in some embodiments, the collected pictures are transmitted to the corresponding cloud platform through a wired or wireless network.

In some embodiments, when watching a live broadcast, a user can listen to the explanation of the commentator of the live broadcast, and the user can also select to enter his voice through live broadcast software, that is, to realize his explanation, and in the user explanation process, the explanation of the user can be uploaded to the cloud platform, and after receiving the explanation of the user, the cloud platform can add a corresponding identifier to the explanation and store the corresponding identifier.

It can be seen that in this application embodiment, when watching the live broadcast, the user not only can listen to the explanation of the commentator, but also can upload the explanation of the user, that is to say, so that the user can have more selectivity when watching the live broadcast, thereby promoting the enjoyment of watching the live broadcast by the user.

In some embodiments, a target commentary content in the at least one commentary content selected by the user when the user watches the live screen is determined; and playing the target comment content.

In some embodiments, since the uploaded commentary of the user is performed in real time, the user can select different commentary while watching the live broadcast, and therefore the enjoyment of watching the live broadcast by the user can be further improved.

In some embodiments, the content of each live broadcast can be stored on the cloud platform, so that the user can conveniently watch and playback, and the user can select favorite commentary when watching and playing back, that is, the commentary content of the user is input during live broadcast, so that the user can select more commentary types when watching and playing the live broadcast. Meanwhile, the comment content and the introduction video can be correspondingly stored, and a user can select more comment content when watching and playing back. When the players of the game watch the replay, the players can also know some opinions of other people about the game according to the comments of other people about the game, so that the players are also beneficial to the movement and the improvement of the strength of the players.

In some embodiments, the above method further comprises: determining voting information of the user on the at least one commentary content; and determining the final commentary content aiming at the live-broadcast picture according to the voting information of the at least one commentary content.

In some embodiments, the final commentary content may be understood as a default commentary of the live view, that is, when the user watches the live view, if the commentary content is not selected, a final commentary content is determined for the user according to the voting information.

In some embodiments, the user may vote on the commentary content to select the commentary that is most preferred, and the commentary that votes most may characterize the commentary style that is probably preferred by most people, so that the commentary may be determined as the final commentary content of the live screen.

In some embodiments, the live broadcast software is mainly installed on various platforms of a personal computer client, a personal computer webpage end, a mobile phone APP end, a mobile phone webpage end, a mobile phone WeChat end and an IPTV (Internet protocol television) end. The user can log in the live broadcast software through the registration of a user name and a password or can directly log in through WeChat.

In some embodiments, the live software can have both live and playback functions, such as: the client can check the currently live content and play back the recorded game; the right side of the live broadcast software display interface can be chatted, commented and popped with other users watching the match; the right side can also display the live data, for example: detailed information such as ball cover, name, position, reward and punishment, calendar year data and the like worn by the player; events in the game, such as goal time, point and the like, can be displayed, the occurrence period of each event can be checked in live broadcasting, the effect of the game can be known even if the events are watched midway, and the point event can be directly jumped to a corresponding interface for watching in recorded broadcasting; the user can enjoy the operations of appreciation, gift giving and the like for the player and the recorder.

In some embodiments, the user may also clip the game video into a highlight compilation using live software and upload the clipped short video to the cloud platform.

In some embodiments, after a student participates in a competition and an athletic meeting, the cloud platform can keep recorded video content, and meanwhile, the cloud platform can permanently store scores kept in the competition and the athletic meeting; the students can claim their scores and generate a report by combining the videos of their competition, when they participate in the interview, they can directly submit the ID of their report, and the interviewer can verify the ID of the report, check the scores of the students in the past years and the video contents of the competition or sports meeting, and verify the results.
