[0048] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0049] In order to solve the above-mentioned technical problems existing in the background technology, an embodiment of the present application provides a barrage motion control solution. In order to facilitate the understanding of the present application solution, the video live broadcast system that may be applied to the present application is first introduced. It can be understood that the video live broadcast system introduced below is only to illustrate the possible application scenarios of the present application solution. The present application solution can also be applied to other application scenarios besides the following scenarios.

[0050] Please refer to Figure 1 , Figure 1 A possible interactive scenario diagram of a video live broadcast system provided by the present application is shown. The video live broadcast system 10 may include a server 100, an anchor terminal 200 and an audience terminal 300 that are in communication connection, and the server 100 may provide video image processing support for the anchor terminal 200.

[0051] In the embodiment of the present application, the host terminal 200 and the audience terminal 300 may be, but are not limited to, a smart phone, a personal digital assistant, a tablet computer, a personal computer, a laptop computer, a virtual reality terminal device, an augmented reality terminal device, etc. In the specific implementation process, there may be multiple host terminals 200 and audience terminals 300 connected to the server 100. Figure 1 Only one host terminal 200 and two viewer terminals 300 are shown. Among them, the host terminal 200 and the viewer terminal 300 can be installed with a live broadcast service program, for example, the service program can be an application APP or a small program related to Internet live broadcast used in a computer or a smart phone.

[0052] In the embodiment of the present application, the server 100 may be a single physical server or a server group consisting of one or more physical servers for performing different data processing functions. The server group may be centralized or distributed (for example, the server 100 may be a distributed system). In some possible implementations, if the server 100 uses a single physical server, different logical server components may be allocated to the physical server based on different business functions.

[0053] Understandably, Figure 1The video live broadcast scene shown is only a feasible example. In other feasible embodiments, the video live broadcast scene may also include only Figure 1 Some of the components shown may also include other components.

[0054] Combine the following Figure 1 The application scenario shown is an exemplary description of the bullet screen motion control method provided in the embodiment of the present application. Figure 2 The barrage motion control method provided in the embodiment of the present application can be executed by the aforementioned server 100. The order of some steps in the barrage motion control method in the embodiment of the present application can be exchanged with each other according to actual needs, or some of the steps can be omitted or deleted. The detailed steps of the barrage motion control method executed by the server 100 are introduced as follows.

[0055] Step S21, determining a bullet screen motion channel extending along a preset motion trajectory direction.

[0056] The barrage movement channel is the channel through which the barrage moves in the live display screen. In the live broadcast room, the barrage moves in the barrage movement channel in the form of a bitmap. In this step, the position coordinates of the barrage movement channel change with the extension direction of the barrage movement channel, or the position coordinates and channel direction of the barrage movement channel change with the extension direction of the barrage movement channel. Exemplarily, the preset motion trajectory includes a curve (for example, a parabola) and a straight line with a certain inclination angle, etc. The specific selection of the preset motion trajectory can be determined according to the preferences of the audience end 300 or the settings of the anchor end 200.

[0057] Step S22, based on the relative position relationship between the bullet screen movement channel and the bullet screen display area, determine the starting position and the ending position of the bullet screen movement channel in the bullet screen display area.

[0058] The barrage will only be displayed in the barrage display area set in the live broadcast screen. Determining the starting and ending positions of the barrage movement channel in the barrage display area can facilitate the subsequent control of the barrage to move in the barrage movement channel located in the barrage display area.

[0059] Step S23, assigning the barrage to the corresponding barrage movement channel, and controlling the barrage to move along the corresponding barrage movement channel in the barrage display area starting from the starting position of the corresponding barrage movement channel until the ending position of the corresponding barrage movement channel.

[0060] In this embodiment, after determining the starting position and ending position of the barrage movement channel, the position coordinates where the barrage should appear in the barrage movement channel when the barrage is refreshed at a preset time interval can be calculated based on the starting position, ending position, movement speed of the barrage, and the function expression corresponding to the preset motion trajectory. At each refresh, the barrage is moved to the corresponding position coordinates until it moves to the ending position of the barrage movement channel, so that the barrage can be controlled to move in the barrage display area.

[0061] The solution provided above can realize the barrage motion control in any preset trajectory direction, achieve various cool barrage effects, enrich the gameplay of barrage, and improve the live interactive effect.

[0062] For further information, please refer to Figure 3 In this embodiment, step S21 can be implemented in the following manner.

[0063] Step S211, determine the number of barrages that can be accommodated simultaneously on the barrage sending starting line.

[0064] The bullet screen sending start line is a position line formed by the starting position of the bullet screen. In this embodiment, the bullet screen sending start line can be located in the bullet screen display area or outside the bullet screen display area. The bullet screen sending start line can be used for multiple bullet screens to be sent from this position.

[0065] Step S212, determining equal division points on the bullet screen sending start line for dividing the bullet screen sending start line into a number of equal parts as the number of bullet screens.

[0066] Generally speaking, the display width of the barrage is the same, so the length of the barrage starting position accommodating different barrages in the barrage sending starting line is equal. In this step, after determining the number of barrages that can be accommodated, the barrage sending starting line can be divided into multiple equal parts equal to the number of barrages, and the corresponding equal division points are obtained.

[0067] Step S213, using the endpoints and the equally divided points of the bullet screen sending start line as starting points to create multiple trajectory lines extending along the preset motion trajectory direction, and the bullet screen motion channels are defined by adjacent trajectory lines.

[0068] Taking the endpoints and the equally divided points of the bullet screen sending start line as the starting points, multiple trajectory lines extending along the preset motion trajectory direction are created. The multiple trajectory lines are parallel to each other. The area between the first trajectory line and the second trajectory line is used as the first bullet screen motion channel, and the area between the second trajectory line and the third trajectory line is used as the second bullet screen motion channel, and so on, to determine multiple bullet screen motion channels.

[0069] Furthermore, in this embodiment, the bullet screen sending start line may be located outside the bullet screen display area. The bullet screen movement channel determined based on the bullet screen sending start line is partially located outside the bullet screen display area. The bullet screen will not be displayed when it moves in this part of the bullet screen movement channel outside the bullet screen display area. The audience needs to wait for a while before they can see the bullet screen. In order to avoid the above situation, please refer to Figure 4 In this embodiment, step S22 can be implemented in the following manner.

[0070] Step S221, based on the relative position relationship between the bullet screen movement channel and the bullet screen display area, determine the intersection points of the bullet screen movement channel and each side of the bullet screen display area.

[0071] Step S222, the intersection point of the barrage movement channel and each side of the barrage display area close to the barrage sending start line is used as the barrage starting point, and the intersection point of the barrage movement channel and each side of the barrage display area far from the barrage sending start line is used as the barrage ending point.

[0072] Step S223, the starting position of the bullet screen movement channel is determined by the bullet screen starting point, and the ending position of the bullet screen movement channel is determined by the bullet screen ending point.

[0073] Through the above method, the starting position and the ending position of the bullet screen movement channel are determined in the bullet screen display area, so that the bullet screen can be directly displayed in the bullet screen display area, avoiding the audience waiting for a long time for the appearance of the bullet screen.

[0074] Furthermore, in order to avoid the situation where the length of the bullet screen movement channel in the bullet screen display area is too short, causing the bullet screen to flash by and the audience cannot perceive the content of the bullet screen well. Figure 5 In this embodiment, after step S22, the bullet screen motion control method provided in this embodiment also includes the following steps.

[0075] Step S24, calculating the length of the bullet screen movement channel in the bullet screen display area based on the starting position and the ending position of the bullet screen movement channel.

[0076] Step S25, detecting whether there is a bullet screen movement channel in the bullet screen display area whose length is less than a preset bullet screen display length threshold.

[0077] Step S26, when the length of the barrage movement channel in the barrage display area is less than the preset barrage display length threshold, adjust the positional relationship between the barrage sending start line and the barrage display area so that the length of the barrage movement channel determined by the adjusted barrage sending start line in the barrage display area is greater than the preset barrage display length threshold.

[0078] Through the above implementation method, each barrage movement channel can have a certain length in the barrage display area, ensuring that when the barrage is assigned to different barrage movement channels, it can be displayed in the barrage display area for a certain length of time (for example, 10 seconds).

[0079] Furthermore, in this embodiment, in order to avoid that different barrage motion channels have inconsistent lengths in the barrage display area, resulting in different display times for the barrages assigned to different barrage motion channels, the barrage motion control method provided in this embodiment also includes the following steps.

[0080] First, obtain the lengths of different bullet screen motion channels in the bullet screen display area.

[0081] Next, the longest bullet screen movement channel in the bullet screen display area is used as a reference bullet screen movement channel, and the movement speed of the bullet screen in the reference bullet screen movement channel is used as a reference speed.

[0082] Then, based on the length of other barrage motion channels in the barrage display area, the length of the reference barrage motion channel in the barrage display area and the reference speed, the barrage motion speed of the other barrage motion channels is determined.

[0083] Exemplarily, in this embodiment, step S23 may be implemented in the following manner.

[0084] The barrage is assigned to the corresponding barrage motion channel, and based on the barrage motion speed control of the corresponding barrage motion channel, the barrage moves along the corresponding barrage motion channel in the barrage display area starting from the starting position of the corresponding barrage motion channel until the ending position of the corresponding barrage motion channel.

[0085] The above method can ensure that the bullet screens assigned to different bullet screen movement channels have the same display time, and avoid high-quality bullet screens being ignored by the anchor due to the short display time when they are assigned to a shorter bullet screen movement channel, thereby affecting the live interactive effect.

[0086] The above scheme is described below by taking the bullet screen display area as a rectangular area and the preset motion trajectory as a straight line from the upper right side of the bullet screen display area to the lower left side of the bullet screen display area as an example.

[0087] like Figure 6As shown, a coordinate system is established with the upper left corner vertex of the barrage display area as the origin o, the left side as the Y axis, and the upper side as the X axis. Suppose now that the barrage is allowed to move from the upper right corner of the barrage display area toward the lower left corner of the barrage display area (tilt angle θ), then the X coordinate of the barrage needs to decrease by a each time, and the Y coordinate increases by a*tanθ each time. Conversely, if the barrage is to be moved from the lower right corner of the barrage display area toward the upper left corner of the barrage display area (tilt angle θ), then the X coordinate of the barrage needs to decrease by a each time, and the Y coordinate needs to decrease by a*tanθ. Similarly, for other motion trajectories (such as parabolas), the change relationship of the position coordinates can also be determined based on the motion trajectory function combined with the above principles.

[0088] Please refer again Figure 6 , when the barrage moves from the upper right of the barrage display area to the lower left of the barrage display area at an angle of 45 degrees, if the barrage sending start line coincides with the right side of the barrage display area, the barrage will all be concentrated in the lower right area, which will cause part of the barrage to be unable to be displayed in the barrage display area. In order to overcome the above problems, the direction of the barrage sending start line can be adjusted. For example, the width of the barrage display area is defined as w, the height is defined as h, the starting point of the barrage sending start line is A, the end point is B, and its intersection with the X-axis is C, where offsetX=offsetX', offsetY=offsetY', offsetY=offsetX*tanθ, and when the tilt angle θ increases, offsetY will also increase accordingly. When the tilt angle θ reaches 90 degrees, offsetY becomes the height of the visible area h. When the tilt angle θ is 0, offsetY should theoretically be 0. Therefore, offsety and θ are in a linear relationship, but when the tilt angle θ is very small, such as 1 degree, in order to ensure that the bullet screen does not flash by, offsetY needs a minimum value to guarantee the bottom line, for example, 1 / 3 of the height h of the bullet screen display area. The value can be determined according to the actual situation. Specifically, it can be determined by adjusting the position relationship between the bullet screen sending start line AB and the bullet screen display area (for example, by translation or relative rotation). When the tilt angle θ is determined, offsetx and offsety are also determined. Next, the length of the bullet screen sending start line AB can be calculated, AB=AC+BC=(w-offsetx)*sinθ+(h-offsetY)*cosθ. In this embodiment, the starting line for sending the barrage can be determined in the following way: first, based on the right side line of the barrage display area, a line segment of a preset length overlapping with the right side line is determined; then, the line segment is translated a certain length toward the top of the barrage display area; then, after translating a preset distance, the translated straight line is rotated relative to the upper right vertex of the barrage display area, and the rotated line segment is used as the starting line for sending the barrage.

[0089] After determining the length of the bullet screen sending start line AB, the bullet screen sending start line AB can be divided into multiple equal parts based on the number of bullet screens that the bullet screen sending start line AB can accommodate. For example, Figure 7 As shown, multiple trajectory lines (straight lines) with an inclination angle of θ are made using the two endpoints and equally divided points (M1 to M4) on the bullet screen sending starting line AB, and a bullet screen movement channel is formed between adjacent trajectory lines.

[0090] Since the barrage sending starting line AB is outside the barrage display area, this will cause some barrage movement channels to be partially not located in the barrage display area, and the barrage will need to wait for a while after being sent before it appears in the barrage display area. For this reason, the intersection points of each barrage movement channel and the barrage display area can be calculated, which are T1~T6 and T1'~T6', respectively. Among them, the intersection points T1~T6 correspond to the intersection points close to the barrage sending starting line AB, and the intersection points T1'~T6' are the intersection points far from the barrage sending starting line AB. In this way, the intersection points T1~T6 can be used as the barrage starting point, and the intersection points T1'~T6' can be used as the barrage ending point. The line segment between adjacent barrage starting points is used as the starting position, and the line segment between adjacent barrage ending points is used as the ending position. For example, the line segment T1T2 is the starting position of the first barrage movement channel, and the line segment T1'T2' is the ending position of the first barrage movement channel.

[0091] For further information, please refer to Figure 8 , Figure 8 A functional module diagram of a bullet screen motion control device 400 provided in an embodiment of the present application, the embodiment of the present application can divide the functional modules of the bullet screen motion control device 400 according to the method embodiment executed by the server, that is, the following functional modules corresponding to the bullet screen motion control device 400 can be used to execute the above-mentioned various method embodiments. Among them, the bullet screen motion control device 400 can include a first determination module 410, a second determination module 420 and a control module 430. The functions of each functional module of the bullet screen motion control device 400 are described in detail below.

[0092] The first determining module 410 is used to determine a bullet screen motion channel extending along a preset motion trajectory direction.

[0093] The barrage movement channel is the channel through which the barrage moves in the display screen. In the live broadcast room, the barrage moves in the barrage movement channel in the form of a bitmap. In this embodiment, the position coordinates of the barrage movement channel change with the extension direction of the barrage movement channel, or the position coordinates and channel direction of the barrage movement channel change with the extension direction of the barrage movement channel. Exemplarily, the preset motion trajectory includes a curve (for example, a parabola) and a straight line with a certain inclination angle, etc. The specific selection of the preset motion trajectory can be determined according to the preferences of the audience end 300 or the settings of the anchor end 200.

[0094] In this embodiment, the first determination module 410 may be used to execute the above step S21. The detailed implementation of the first determination module 410 may refer to the above detailed description of step S21.

[0095] The second determining module 420 is used to determine the starting position and the ending position of the bullet screen movement channel in the bullet screen display area based on the relative position relationship between the bullet screen movement channel and the bullet screen display area.

[0096] The barrage will only be displayed in the barrage display area set in the live broadcast screen. Determining the starting and ending positions of the barrage movement channel in the barrage display area can facilitate the subsequent control of the barrage to move in the barrage movement channel located in the barrage display area.

[0097] In this embodiment, the second determination module 420 can be used to execute the above step S22. The detailed implementation of the second determination module 420 can refer to the detailed description of the above step S22.

[0098] The control module 430 is used to allocate the barrage to the corresponding barrage movement channel, and control the barrage to move along the corresponding barrage movement channel in the barrage display area starting from the starting position of the corresponding barrage movement channel until the end position of the corresponding barrage movement channel.

[0099] After determining the starting position and the ending position of the bullet screen movement channel, the control module 430 can calculate the position coordinates where the bullet screen should appear in the bullet screen movement channel when the bullet screen is refreshed at a preset time interval based on the starting position, the ending position, the movement speed of the bullet screen, and the function expression corresponding to the preset movement trajectory. At each refresh, the control module 430 moves the bullet screen to the corresponding position coordinates until the bullet screen moves to the ending position of the bullet screen movement channel, so that the bullet screen can be controlled to move in the bullet screen display area.

[0100] In this embodiment, the control module 430 can be used to execute the above step S23. The detailed implementation of the control module 430 can refer to the detailed description of the above step S23.

[0101] It should be noted that it should be understood that the division of the various modules in the above device or system is only a division of logical functions. In actual implementation, they can be fully or partially integrated into one physical entity, or they can be physically separated. And these modules can all be implemented in the form of software (for example, open source software) that can be called by the processor; they can also be implemented in the form of hardware; some modules can also be implemented in the form of software called by the processor, and some modules can be implemented in the form of hardware. As an example, the control module 430 can be implemented by running a separate processor, and can be stored in the memory of the above device or system in the form of program code. The functions of the above control module 430 are called and executed by a processor of the above device or system. The implementation of other modules is similar to it, which will not be repeated here. In addition, these modules can be fully or partially integrated together, or they can be implemented independently.
