[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In order to solve the problems in the prior art, the present invention proposes a live broadcast system to meet the needs of high-quality live broadcast in multiple scenes. The live broadcast system is described below. Figure 1 As shown, including but not limited to the following modules:

[0041] Lighting module, recording module, track module and control module;

[0042] The lighting module is used to monitor the light conditions of the on-site environment in real time and adjust the brightness and color temperature of the lighting equipment according to the lighting control instructions of the control module;

[0043] The recording module includes a camera unit and a microphone array unit, the camera unit is arranged on the track module, and the recording module is used to collect sound information and video information of the target object;

[0044] The track module is used to control the camera unit to move along a preset path according to the device control instruction of the control module;

[0045] The control module is used to generate corresponding lighting control instructions according to the light conditions to adjust the brightness and color temperature of the lighting equipment; and is used to generate corresponding equipment control instructions according to the video information to control the camera unit to move along the preset path. The control module is wirelessly connected to the lighting module, recording module and track module.

[0046] The function of the lighting module is to automatically adjust the brightness and color temperature of the lighting equipment according to the lighting conditions of the scene, so as to ensure the best shooting effect and visual comfort. During use, the lighting module continuously monitors the changes in the light on the scene through the light intensity and color temperature sensors. Once the ambient light changes are detected, the control module will automatically generate lighting control instructions to instruct the dimming and color adjustment unit to adjust the brightness and color temperature of the lighting equipment to ensure that the light is always kept in the best state during video shooting.

[0047] The recording module is used to collect the sound and video information of the target object and transmit it to the control module. The recording module is equipped with multiple microphones and high-definition cameras, which can collect audio and video information of the target object in all directions. The microphone array is arranged in an array to ensure that the sound in each area can be clearly collected; the camera uses autofocus and auto exposure technology to ensure the stability of video quality. All collected audio and video information is transmitted to the control module in real time through the second communication unit.

[0048] The main function of the track module is to control the camera to move smoothly along the track according to the instructions of the control module to achieve automatic camera tracking. In actual operation, the visual tracking unit continuously tracks the movement of the target object and generates accurate movement instructions by analyzing the real-time position data of the target. After receiving the instructions, the track motion control unit drives the camera to move smoothly along the track. At the same time, the shock-absorbing buffer unit ensures that the camera will not be affected by vibration during movement, ensuring image stability.

[0049] The control module is the core part of the system, which is responsible for receiving real-time data from the lighting module, recording module and track module, and generating control instructions based on these data. In actual applications, the control module receives data from each module through the communication protocol unit, and generates corresponding control instructions through the control instruction issuing unit. Users can view the device status and perform real-time operations through the interactive terminal. In addition, the control module can also automatically generate control instructions according to the preset algorithm to optimize the collaborative work between devices.

[0050] The specific workflow is as follows:

[0051] The lighting module collects on-site light data through sensors and transmits the data to the control module.

[0052] The control module generates lighting adjustment instructions according to the real-time light conditions and sends them to the dimming and color adjustment unit to automatically adjust the brightness and color temperature of the lighting equipment.

[0053] The recording module collects audio and video information of the target object through a microphone array and a camera, and transmits it to the control module in real time.

[0054] The track module controls the camera to move smoothly along the track, always aiming at the target object.

[0055] The control module generates camera movement adjustment instructions based on the data provided by the sensors on the track module, and adjusts the lighting, recording equipment, etc. to optimize the on-site effect.

[0056] As a further optional embodiment, the lighting module includes: a light intensity sensor unit, a color temperature sensor unit, a first communication unit and a dimming and color adjustment unit, and the light condition includes light intensity and light color temperature;

[0057] The light intensity sensor unit is used to monitor the light intensity of the on-site environment in real time;

[0058] The color temperature sensor unit is used to monitor the light color temperature of the on-site environment in real time;

[0059] The first communication unit is used to forward the light intensity collected by the light intensity sensor unit and the light color temperature collected by the color temperature sensor unit to the control module;

[0060] The dimming and color adjustment unit is used to execute the lighting control instructions of the control module to adjust the brightness and color temperature of the lighting equipment.

[0061] Through the above implementation modes, the live broadcast system of the present invention can work together efficiently and accurately to provide high-quality real-time recording and live broadcast experience in a dynamic environment.

[0062] As a further optional embodiment, the recording module includes: a second communication unit;

[0063] The microphone array unit is composed of a plurality of microphones and is used to collect sound information of the target object;

[0064] The camera unit includes a plurality of high-definition cameras, which are mounted on the track module and are used to collect video information of the target object;

[0065] The second communication unit is used to forward the sound information and the video information to the control module.

[0066] Specifically, the microphone array unit is composed of multiple microphones in an array, which can efficiently collect the sound information of the target object. The unit covers a larger range of space by arranging multiple microphones in a circular or linear array, thereby ensuring comprehensive sound collection. The position and spacing of each microphone are precisely designed to ensure that the sound information in different areas can be clearly captured while avoiding blind spots or sound loss. The microphone array unit can sensitively capture the speech or other sound information of the target object in a live environment. The configuration of multiple microphones effectively enhances the directionality and receiving range of the array, ensuring all-round audio collection, and is suitable for a variety of application scenarios such as lectures and meetings.

[0067] The camera unit includes multiple high-definition cameras, which are installed on the track module. By placing multiple high-definition cameras in the track module, the camera unit can provide all-round video information of the target object, ensuring that video images from all angles can be captured in real time during the movement of the target object. The arrangement of multiple high-definition cameras ensures multiple shooting angles, which can simultaneously capture the front, side and other required angles of the target object. The camera uses a high-resolution sensor to ensure clear and detailed images. The camera of the camera unit is installed on the track module and can move smoothly in the horizontal or vertical direction on the track. The movement of the camera is controlled by the track module to ensure that it accurately follows the movement trajectory of the target object. In actual use, the camera unit automatically adjusts the shooting angle and focal length of the camera according to the position and movement of the target object, thereby ensuring that the target object always appears in the picture and maintains clear image quality.

[0068] The second communication unit is used to transmit the audio and video information collected by the microphone array unit and the camera unit to the control module in real time. The communication unit supports high-speed and stable data transmission to ensure the real-time and synchronization of audio and video signals. The second communication unit can use standard wireless communication protocols (such as Wi-Fi, Bluetooth or other suitable video streaming protocols) for data transmission. In this embodiment, the second communication unit is not only responsible for the transmission of audio and video data, but also has data compression and encryption functions to improve the efficiency and security of data transmission. The unit transmits the audio and video information to the control module via a wireless network for subsequent processing or storage.

[0069] As a further optional embodiment, the recording module further includes: a sound processing unit and an image processing unit;

[0070] The sound processing unit is used to optimize the sound information collected by the microphone array unit and perform noise suppression and echo cancellation processing;

[0071] The image processing unit is used to optimize the video information collected by the camera unit and perform automatic white balance, sharpening and denoising processing.

[0072] Specifically, the main function of the sound processing unit is to optimize the sound information collected by the microphone array unit to ensure that the audio signal is clear and pure, and to remove environmental noise and echo. This unit includes the following key parts:

[0073] Noise suppression: The noise suppression module can identify and remove background noise in the environment (such as wind noise, mechanical noise, equipment noise, etc.), so that the recorded sound only contains the voice information of the target object. The noise suppression algorithm effectively reduces the impact of unwanted noise through technologies such as spectrum analysis and adaptive filtering.

[0074] Echo Cancellation: The echo cancellation module can effectively remove the echo or reverberation generated in the audio recording, especially in large spaces or conference rooms. When sound reflections produce echoes, the echo cancellation module can restore clear sound signals through time domain and frequency domain processing.

[0075] Sound Enhancement: After noise suppression and echo cancellation, the Sound Enhancement module further optimizes the target subject’s sound, enhancing the clarity and naturalness of the speech, making it easier to hear during recording or live streaming.

[0076] The sound processing unit receives the audio signal from the microphone array unit and processes it in real time. Before the signal is transmitted to the control module, the audio signal has been processed by noise suppression, echo cancellation and enhancement to ensure that the final recorded audio quality is clear and interference-free.

[0077] The main function of the image processing unit is to optimize the video information collected by the camera unit to ensure that the recorded video quality is stable and clear, and can adapt to different lighting and environmental changes. The unit includes the following processing modules:

[0078] Automatic white balance: The automatic white balance module automatically adjusts the color temperature of the image based on the video image captured by the camera to ensure true color reproduction and avoid color cast caused by poor lighting conditions. The module automatically adjusts the color temperature of the light source by analyzing white or gray objects in the video to ensure the natural tone of the image.

[0079] Image sharpening: The image sharpening module improves the clarity and detail level of the image by enhancing the edge details in the image. The sharpening algorithm detects the edge of the image and performs reverse blur processing to make the outline of people or other important objects clearer, thereby improving the video viewing experience.

[0080] Denoising: The image denoising module is used to remove noise and stray light in video images, especially when shooting in low-light environments, which often produces image noise. The denoising algorithm improves image quality by smoothing the pixel data in the image, removing unnecessary noise, and preserving details and edges.

[0081] The image processing unit optimizes the video signal collected by the camera unit in real time. Before the video information is transmitted to the control module, the image has been processed by automatic white balance, sharpening and denoising to ensure clear and natural image quality to adapt to various shooting environments.

[0082] As a further optional embodiment, the track module includes: a visual tracking unit and a track motion control unit;

[0083] The visual tracking unit is used to generate a motion tracking instruction according to the position and motion trajectory of the target object;

[0084] The track motion control unit is used to control the camera unit to move along the track according to the motion tracking instruction issued by the visual tracking unit.

[0085] In a further optional embodiment of the present invention, the track module includes a visual tracking unit and a track motion control unit, which are used to achieve automatic tracking and precise control of the camera, thereby providing smooth and precise camera movement to achieve high-quality shooting effects.

[0086] The main function of the visual tracking unit is to generate motion tracking instructions in real time according to the position and motion trajectory of the target object. Based on computer vision technology, the unit can automatically identify the position of the target object and analyze its motion trajectory, thereby controlling the movement of the camera unit.

[0087] Specifically, a camera captures a scene image in real time and identifies the location of the target object. Object detection algorithms such as convolutional neural networks (CNNs) can quickly identify the location of the target object (e.g., a speaker or presenter) and mark its location in the image.

[0088] Next, based on the information provided by the target detection module, the target object's motion trajectory and speed are analyzed. The target object's motion path is calculated through a tracking algorithm (such as Kalman filtering or optical flow method) to predict the target object's future position.

[0089] Subsequently, according to the motion trajectory of the target object, the motion instruction generation module generates precise motion tracking instructions to instruct the camera to move along the track to aim at the target object. The motion instructions can be adjusted in real time to ensure that the camera always follows the movement of the target object.

[0090] The main function of the track motion control unit is to control the camera unit to move smoothly and accurately along the track according to the motion tracking instructions issued by the visual tracking unit.

[0091] Specifically, the track motion control unit uses high-precision drive devices such as electric servo drives or stepper motors to achieve precise control of the camera movement. And through position sensors (such as encoders, photoelectric sensors, etc.), it is used to monitor the position of the camera on the track in real time to ensure the accuracy of the camera movement. The data fed back by the track sensor will be fed back to the motion control unit in real time to adjust the motion instructions of the drive system. At the same time, deceleration and acceleration control algorithms are used to smoothly drive the camera to move on the track, avoid sudden acceleration or deceleration, and ensure the stability of the picture during movement. In addition, the smooth control of the camera can be accurately adjusted by the servo motor to avoid jitter or unstable movement.

[0092] After receiving the motion command from the visual tracking unit, the track motion control unit controls the camera to move along the preset track direction. Through the precise drive system and real-time feedback mechanism, the control unit can adjust the camera position in real time to ensure the accuracy and stability of following the target object.

[0093] As a further optional embodiment, the track module further includes: a shock absorbing and buffering unit and a sensor feedback unit;

[0094] The shock absorbing and buffering unit is arranged on the track motion control unit, and is used to reduce the impact and vibration when the camera unit moves;

[0095] The sensor feedback unit is used to monitor the track load on the track module and the motion state of the camera unit to adjust the motion tracking instruction.

[0096] In a further optional embodiment of the present invention, the track module further includes a shock absorbing buffer unit and a sensor feedback unit, which are used to further improve the stability and accuracy of the camera unit during the movement. Through these two additional units, the impact and vibration of the camera unit during the track movement can be effectively reduced, ensuring the stability and clarity of the captured images.

[0097] The main function of the shock-absorbing and buffering unit is to reduce the impact and vibration that the camera unit may encounter during its movement on the track to ensure image stability and picture quality. This unit is usually set on the track motion control unit and directly participates in the movement of the camera.

[0098] Specifically, by using shock-absorbing elements such as springs, rubber pads, hydraulic buffers, etc., the vibration of the camera caused by track friction, speed changes or external impacts can be reduced. The shock-absorbing device can effectively absorb and disperse the impact force during movement, reducing the impact of these impacts on the picture quality.

[0099] The buffer system uses soft start and soft stop control to avoid excessive instantaneous impact or sudden stop when the camera moves. The buffer device can achieve smooth transition during the acceleration and deceleration of the camera to ensure stability during movement.

[0100] When the track module is working, the shock-absorbing buffer unit controls the movement of the camera in real time, especially in the start and stop stages of the camera, to reduce the impact force and prevent the violent movement of the camera unit from having an adverse effect on the stability of the picture.

[0101] The main function of the sensor feedback unit is to monitor the track load and the motion status of the camera unit in real time, and feed this data back to the track motion control unit. This unit ensures that the camera unit can always run smoothly and can adjust the motion tracking instructions in time when the load changes, thereby improving the response accuracy and stability of the system. The unit includes the following parts:

[0102] Load sensor: Load sensor is used to monitor the weight or other external forces on the camera unit on the track. By monitoring the load changes in real time, the system can adjust the movement speed and acceleration of the camera unit to avoid unstable movement or jamming of the camera due to excessive or uneven load. Track load refers to the allowable load that the outer ring of the bearing and the track material in contact can withstand under long-term repeated use.

[0103] Motion state sensor: This sensor is used to monitor the real-time motion state of the camera unit on the track, including the position, speed, acceleration, etc. of the camera unit. By monitoring the motion state, the system can detect whether the camera unit is operating normally and whether there are any motion anomalies, such as unstable acceleration or deceleration.

[0104] When the load sensor or motion state sensor detects an abnormality, the sensor feedback unit transmits the data to the track motion control unit, and the control unit adjusts the motion command according to the information provided by the sensor to ensure smooth movement of the camera unit.

[0105] In actual applications, the sensor feedback unit can quickly detect abnormal conditions that may affect the smoothness of camera movement by monitoring the track load and the motion state of the camera unit in real time. When an abnormality occurs, the control unit will adjust the speed, acceleration and other parameters of the track movement based on the feedback information to ensure that the camera unit moves smoothly and efficiently along the track.

[0106] As a further optional embodiment, the control module includes: a communication protocol unit, a control instruction issuing unit;

[0107] The communication protocol unit is used to forward the light conditions collected by the lighting module and the video information collected by the recording module to the control instruction issuing unit. The control instruction issuing unit generates lighting control instructions according to the light conditions and generates device control instructions according to the video information. The communication protocol unit is also used to receive lighting control instructions and device control instructions from the control instruction issuing unit, and send them to the lighting module and the track module respectively.

[0108] The control instruction issuing unit is used to generate corresponding control instructions according to the real-time data collected by the device.

[0109] In a further optional embodiment of the present invention, the control module includes a communication protocol unit and a control instruction issuing unit, which is used to coordinate the work of each device in the system and generate control instructions according to real-time data to achieve intelligent control. The module obtains real-time data collected by the device, generates control instructions and forwards them to the target module, thereby optimizing the working efficiency and accuracy of the entire system.

[0110] The main function of the communication protocol unit is to realize real-time data communication between the control module and other devices. This unit is responsible for obtaining the real-time data collected by each device and passing this data to the control instruction issuing unit. The communication protocol unit is also used to forward the control instructions from the control instruction issuing unit to the target module to ensure efficient collaboration between devices.

[0111] During use, the communication protocol unit communicates with other devices through wireless networks or wired connections. It obtains real-time data from the devices regularly or on demand, and transmits these data to the control instruction issuing unit according to the needs of the control module. At the same time, when the control unit generates control instructions, the communication protocol unit ensures that these instructions are correctly forwarded to the target module, such as the lighting module, camera or sound system.

[0112] The main function of the control instruction issuing unit is to generate corresponding control instructions according to the real-time data received from the communication protocol unit and pass the instructions to the target module. This unit realizes intelligent control and system optimization through data analysis and processing.

[0113] In a specific implementation, the control instruction issuing unit first receives data input from the communication protocol unit. Then, based on these data, combined with preset control logic or real-time calculation, a corresponding control instruction is generated. The generated instruction is then transmitted to the target module through the communication protocol unit to perform the adjustment or adjustment operation.

[0114] As a further optional embodiment, the control module further includes: an interactive terminal;

[0115] The interactive terminal is used to display real-time data collected by the device and to obtain device operation instructions input by the user.

[0116] In a further optional embodiment of the present invention, the control module further includes an interactive terminal for displaying real-time data collected by the device and obtaining device operation instructions input by the user. The interactive terminal provides real-time feedback of the device status through an intuitive user interface and allows the user to conveniently operate the system, thereby improving the operability and flexibility of the system.

[0117] The main function of the interactive terminal is to serve as an interface between the user and the control module, provide real-time data display, and receive device operation instructions input by the user. The interactive terminal usually includes a touch screen, a display screen, and related input devices (such as buttons, keyboards, mice, etc.).

[0118] The interactive terminal displays real-time data from various modules of the system (such as lighting module, recording module, track module, etc.). The data can include light intensity, audio signal, camera position, device status, etc. Through the graphical interface, users can intuitively view the real-time operation status of the system.

[0119] The interactive terminal provides a user input operation interface, allowing users to input instructions as needed, such as adjusting the brightness of lighting equipment, controlling the movement of the camera, adjusting audio settings, etc. Users can easily control the device and adjust system settings through touch screens, virtual buttons or other input methods.

[0120] The interactive terminal not only displays real-time data, but also provides feedback based on the user's operation. For example, when the user adjusts the lighting brightness through the touch interface, the interactive terminal will display the adjusted brightness value in real time, ensuring that the results of the user's operation can be fed back in a timely manner.

[0121] In actual applications, the interactive terminal obtains real-time data and displays it through the connection with the control module. When the user needs to adjust the device settings, he can input instructions through the interactive terminal (such as touching buttons, sliding bars, etc.), and the system will generate corresponding control instructions based on the user's input and transmit them to the target module (such as lighting equipment, cameras, etc.), thereby realizing the control and adjustment of the equipment.

[0122] The interactive terminal obtains real-time data of each module of the system from the control module, such as light intensity, camera position, volume data, etc., and displays it to the user in real time. The data is displayed through charts, indicator lights, digital displays, etc. to ensure that users can accurately understand the system status.

[0123] The user operates the system through the interactive terminal. The user can adjust the parameters of lighting, audio, camera and other equipment through touch, buttons or other input devices. For example, the user can adjust the brightness through the slider, adjust the angle of the camera by selecting the button, or enter other custom control instructions.

[0124] After receiving the user's operation instruction, the interactive terminal forwards the instruction to the relevant equipment (such as lighting module, track module, etc.) through the control module. The control module generates corresponding control commands according to the user's instructions and transmits them to the target equipment to ensure that the equipment executes the user's operation.

[0125] After the device executes the user's instructions, the interactive terminal will update the displayed information in real time to feedback the new status or parameters of the device. The user can further adjust the device settings based on the feedback to ensure that the system runs as required.

[0126] As a further optional embodiment, the track motion control unit includes: an embedded ceiling track and a pan / tilt control device;

[0127] The pan / tilt control device is used to control the camera unit to move on the embedded ceiling track, and the embedded ceiling track is driven by magnetic suspension.

[0128] In a further optional embodiment of the present invention, the track motion control unit includes an embedded ceiling track and a pan / tilt control device. The embedded ceiling track adopts magnetic levitation drive technology to achieve higher precision, low friction and smooth movement, while the pan / tilt control device is used to accurately control the movement of the camera unit on the track.

[0129] The main function of the recessed ceiling track is to provide a smooth and precise movement path for the camera unit. Unlike traditional floor tracks, the recessed ceiling track is hidden in the ceiling, which not only saves space but also avoids interfering visual effects. Its key features include:

[0130] The embedded ceiling track uses magnetic levitation drive technology, which uses magnetic force to keep the camera unit at a certain suspension distance from the track surface, reducing friction and wear, thereby achieving smoother and more efficient movement. Magnetic levitation drive can effectively eliminate the friction and vibration problems that may occur in traditional mechanical drives, and improve the movement accuracy and stability of the camera unit.

[0131] Due to the low friction characteristics of the magnetic suspension drive, the movement of the camera unit is more precise and less susceptible to interference from the external environment. The track is designed with stability and noise control in mind, ensuring that the noise generated during the movement of the camera unit is minimized.

[0132] The embedded track can be hidden in the ceiling, saving space and not affecting the interior aesthetics. Due to its concealedness, this design is very suitable for places such as modern conference rooms or classrooms that require high integration and aesthetics.

[0133] The embedded ceiling track uses magnetic levitation drive technology to achieve smooth movement of the camera unit. The camera unit can move precisely along the track and can accelerate, decelerate or stop at a fixed point according to actual needs, ensuring clear images from every shooting angle.

[0134] The PTZ control device is mainly used to control the movement of the camera unit on the track to ensure that the camera can maintain alignment with the target object at any time. The device is usually equipped with multiple degrees of freedom control functions (such as horizontal rotation, vertical pitch and focal length adjustment) so that the camera unit can flexibly adjust the shooting angle. The key features of the PTZ control device include:

[0135] The pan / tilt control device usually has at least two degrees of freedom, namely horizontal rotation and vertical pitch. In this way, the camera unit can adjust its shooting angle according to real-time needs to ensure that the target object is always in the center of the picture.

[0136] The PTZ control device can achieve precise motion control through servo motors or stepper motors. The system can automatically adjust the PTZ angle according to the current position of the camera and the position of the target object to ensure that the camera unit always follows the target object.

[0137] The PTZ control device works in conjunction with the embedded ceiling track, allowing the camera unit to not only move smoothly along the track, but also adjust the shooting angle during movement to cope with dynamic changes in the target object.

[0138] The pan / tilt control device adjusts the pitch and rotation angle of the camera unit by controlling the servo motor. The control signal is transmitted by the track motion control unit, and the pan / tilt angle is adjusted according to the real-time position of the camera unit and the motion trajectory of the target object to ensure that the camera unit is always aimed at the target object.

[0139] The magnetic levitation drive technology provides low-friction, high-precision motion control, significantly improving the stability of the camera unit and avoiding the friction and vibration in traditional mechanical drive systems. The embedded track is hidden in the ceiling and does not affect the beauty of the interior decoration. It is suitable for high-end live broadcasts, conferences and education venues in modern scenes.

[0140] As a further optional embodiment, the microphone array unit is a circular array consisting of 6-12 microphones, and the distance between each microphone is 30-50 cm.

[0141] The microphone array unit adopts a ring array structure and includes 6 to 12 microphones. The spacing between each microphone is 30-50cm. This array design can effectively capture sound information in the environment and is particularly suitable for scenes that require high-quality audio collection.

[0142] The ring microphone array can evenly distribute the sound collection area, thereby achieving all-round sound capture and reducing bias or blind spot problems. Through the collaborative work of multiple microphones, high-precision sound positioning and noise suppression can be provided to improve audio quality.

[0143] According to actual needs, the number of microphones can be selected from 6 to 12, which can provide a wider coverage and stronger sound collection capabilities. The distance between each microphone is set between 30-50cm, which can avoid interference and ensure sensitive capture of surrounding sounds.

[0144] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.

[0145] Through the description of the above implementation methods, those skilled in the art can clearly understand that each implementation method can be implemented by means of software plus a necessary general hardware platform, and of course, it can also be implemented by hardware. Based on this understanding, the above technical solution is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each embodiment or some parts of the embodiments.

[0146] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
