Detailed Description
Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present application.
First, it should be noted that the method for publishing the multimedia information special-shaped screen in the embodiment of the present application is mainly used for realizing normal display and play of program contents with an unconventional resolution (that is, a program resolution is greater than a preset resolution) on a display device. The preset resolution can be flexibly set according to actual conditions, and is usually 1920 × 1080.
That is to say, the method for publishing the multimedia information special-shaped screen in the embodiment of the application is mainly applied to large scenes such as exhibition halls and airports and is suitable for large display devices, for example: hairtail screen, spliced screen or other specially-shaped display screen and the like. In an application scenario with a resolution greater than 1920 × 1080, the playing and presentation of the program content is not implemented by one playing terminal and one display device, but by a plurality of playing terminals.
Fig. 1 shows a flow chart of a multimedia information irregular screen publishing method according to an embodiment of the application. As shown in fig. 1, the method includes: step S100, after receiving a program production instruction, acquiring the resolution of the currently input program. Here, it will be understood by those skilled in the art that the program resolution may be arbitrarily specified or defined by the user according to actual needs. Namely, after receiving a program production instruction, pushing and displaying a window interface with a user-defined program resolution. The user determines the resolution of the currently produced program content in a pop-up window interface in a selection or direct input mode.
And step S200, performing program canvas layout according to the program resolution and the picture output resolution of each player configured by the client. Here, it should be noted that the program canvas to be laid out differs depending on the resolution of the program. When the program resolution is less than or equal to the preset resolution, a program canvas can be directly generated as a carrier of the whole program content. When the program resolution is greater than the preset resolution, the program canvas usually includes a plurality of sub-canvases during layout of the program canvas, and the plurality of sub-canvases are arranged correspondingly according to the program resolution and the screen output resolution of each player configured by the client to form the whole canvas of the program content. It should be further explained that, in the present application, the program canvas may be understood as a virtual screen display range, and may also be thought of as a display screen during the playing of an actual program.
Meanwhile, the preset resolution can be flexibly set according to the actual situation. Such as: when the screen output resolutions of the players configured by the client are the same, the preset resolution may be the screen output resolution of each configured player. That is, when the screen output resolutions of the players are the same, the screen output resolution of any one of the players is directly obtained as the preset resolution, and the layout of the program canvas is performed according to the self-defined program resolution and the screen output resolution of any one player.
And selecting the minimum picture output resolution from the picture output resolutions of the players, and setting the minimum picture output resolution as a preset resolution. When the program canvas layout is performed, the layout can be performed according to the program resolution and the minimum picture output resolution.
Then, through step S300, corresponding multimedia content is loaded on the program canvas that is laid out, so as to implement the production of different areas of the program content. Here, it should be noted that the loaded multimedia content may be various contents such as pictures, videos, letters, clocks, weather, carousel, PPT, Word, PDF, Excel, Iframe, video streams, music, and the like, and is not limited herein. Meanwhile, as will be understood by those skilled in the art, the program content produced in the present application refers to the program canvas generated after the required multimedia content is loaded.
Finally, in step S400, the program content and the segmentation information of the program content are sent to the client, and the players in the client cooperate to play and display the program content. Here, it should be explained that the segmentation information of the program content refers to a corresponding relationship between each sub-canvas in the program canvas and the loaded multimedia content.
That is to say, according to the method for publishing the multimedia information special-shaped screen, when a program is manufactured at the server side, the resolution of the program content is customized, and then the layout of the program canvas is performed according to the customized program resolution and the picture output resolution of the player configured by the client side, so that the well-laid program canvas can be matched with the resolution of the display device of the client side. After the program content is manufactured, the program content is sent to the client side to be displayed and played, and meanwhile, the segmentation information of the program content is sent, so that each player of the client side can display and play the program content cooperatively according to the segmentation information, the function of displaying point-to-point playing of the program content and the output of the client side is realized, the program content with different program resolutions can be flexibly formulated according to actual conditions when the special-shaped screen of the multimedia information is released, the limitation of the resolution of conventional display equipment is avoided, and the displayed content is more flexible and diversified. And finally, the high matching between the program content and the display equipment is achieved, and various personalized requirements of users are met.
According to the foregoing, in the method for publishing a special-shaped screen of multimedia information, a program canvas refers to a virtual screen display range, and can also be understood as a screen for playing an actual program. That is to say, in the method for publishing a special-shaped screen of multimedia information according to the embodiment of the present application, the program canvas is laid out according to the program resolution and the picture output resolution of each player configured by the client, so that the finally prepared program content can be completely prepared according to the display range of the actual screen, which effectively improves the high matching degree between the program content and the actual display range of the display device.
Further, when the layout of the program canvas is performed according to the program resolution and the screen output resolution of each player, the following specific implementation can be performed.
The method comprises the steps of calculating the multiples of program resolution and picture output resolution, determining the horizontal coordinate pixel value and the vertical coordinate pixel value of a program canvas according to the calculated multiples, and then determining the number of the sub-canvases and the arrangement mode of the sub-canvases based on the horizontal coordinate pixel value and the vertical coordinate pixel value of the program canvas.
Here, when the multiples of the program resolution and the screen output resolution are calculated, the multiples of the horizontal coordinate pixel value of the program resolution and the horizontal coordinate pixel value of the screen output resolution and the multiples of the vertical coordinate pixel value of the program resolution and the vertical coordinate pixel value of the screen output resolution are calculated, respectively, and then the layout of the program canvas is performed based on the two calculated multiples.
Meanwhile, as can be seen from the foregoing, the screen output resolutions of the players configured by the client may be the same or different. Therefore, when the program resolution and the picture output resolution are multiplied and the layout of the program canvas is performed according to the multiple, the program resolution and the picture output resolution can be divided into two cases.
One situation is: the output resolution of the pictures of the players configured by the client is the same. In this case, when the layout of the program canvas is performed, any one of the screen output resolutions can be extracted directly from the screen output resolutions of the respective players, and then the multiples of the program resolution and the screen output resolution can be calculated.
The other case is that: the output resolution of the pictures of the players configured by the client is different. In this case, the minimum screen resolution may be extracted from the screen output resolutions of the players, and then the multiples of the program resolution and the minimum screen output resolution are calculated, and then the layout of the program canvas is performed according to the calculated multiples.
In order to more clearly describe the layout of the program canvas, the following description will be given taking the same screen output resolution of each player and 1920 × 1080 as an example.
Referring to fig. 2, when the program resolution is set to: 30720 × 1080, at this time: 30720/1920 is 16, 1080/1080 is 1, the two multiples are 16 and 1 respectively, so that 16 layouts are needed in the horizontal direction of the program canvas and only one layout is needed in the vertical direction. That is, the layout of the program canvas may be determined to be in the form of 1 row and 16 columns. Here, it should be noted that fig. 2 is only a schematic diagram of the embodiment, and only a part of the program canvas is shown. That is, FIG. 2 only shows a partial layout of the first 4 sub-canvases of the program canvas laid out in this embodiment, and the layout of the next 12 sub-canvases is the same as the layout of the first 4 sub-canvases. Meanwhile, as can be understood by those skilled in the art, the resolution of each sub-canvas block is 1920 × 1080.
Referring to fig. 3, when the program resolution is set to 3840 × 2160, the following are calculated: 3840/1920 is 2, 2160/1080 is 2, the two multiples are 2 and 2 respectively, so that it can be determined that the program canvas needs to be laid out 2 in the horizontal direction and 2 in the vertical direction, and thus the layout of the program canvas is determined to be 2 rows and 2 columns.
After the layout of the program canvas is completed, the corresponding multimedia content may be loaded on the program canvas. In a possible implementation manner, loading may be performed in a manner of dragging a control. Namely, acquiring a control corresponding to the currently triggered multimedia content, and adding the corresponding multimedia content to the program canvas according to the triggered control.
For example, referring to FIG. 4, various different types of controls for multimedia content may be preloaded in the left control bar. Therefore, when the multimedia content is added, the control in the control bar is directly dragged to the corresponding display position in the program canvas by adopting the control dragging method, and the addition of the multimedia content on the program canvas can be realized.
The method for triggering and dragging the control is adopted, so that the multimedia content is loaded on the program canvas more flexibly, the operation mode for loading the multimedia content is effectively simplified, and the program content is enriched.
In addition, it should be noted that, in the multimedia information irregular screen publishing method according to the embodiment of the present application, when a program is produced in any of the above manners, the multimedia information publishing system platform based on may adopt a B/S architecture, manage the broadcast terminal through a network, and may configure various management functions such as resource management, terminal management, program management, and user management.
Among them, resource management is mainly used to store various multimedia resources used in program production in advance. The terminal management is mainly used for acquiring and storing configuration information of each player configured by the update client, including information such as picture output resolution of each player. The program management is mainly used for executing any one of the program production processes to realize the production of program contents with any resolution. The user management is used for setting different authorities and the like for different users.
In the program management, a blank program canvas is provided, the program canvas is laid out, and meanwhile, various controls in a left control bar are dragged by a mouse to realize the program production.
Therefore, according to the multimedia information special-shaped screen publishing method, when the server side makes the program content, the size of the program resolution is defined by user, the program canvas is distributed according to the defined program resolution and the picture output resolution of the player of the client side, and then the corresponding multimedia content is loaded in the distributed program canvas to make the program content, so that the made program content is highly matched with the display screen of the display equipment of the client side, and conditions are provided for meeting the personalized display requirements of users.
In addition, it should be noted that after the program content is manufactured in any one of the foregoing multimedia information special-shaped screen publishing manners, the manufactured program content needs to be sent to the client, and the program content is played and displayed by each player of the client in a cooperative manner. In the implementation aspect of the multimedia information distribution terminal player, the terminal program needs to be received and played, and the terminal needs to be linked and the like according to the actual situation.
Referring to fig. 5, when the resolution of a single device cannot cover the resolution of the special-shaped screen, multiple players are required to play a program content at the same time, but each player is required to play a different area of the program content, so that the program content can be displayed and played on the display device completely and normally.
In a possible implementation manner, when the players configured by the client cooperate to play and display the program content, the following manner may be implemented.
That is, referring to fig. 6, the program content and the slicing information transmitted by the server are received first, and then different areas of the program content are allocated to different players according to the slicing information based on the picture output resolution of each player. Here, it will be appreciated by those skilled in the art that different regions of the program content correspond to different sub-canvases within the program canvas. Then, the players are controlled to synchronously play different areas of the program content respectively.
That is, after the client receives the program content and the segmentation information sent by the server, different areas of the program content are correspondingly allocated to different players according to the segmentation information, so that the players only play the received program part content when playing. When different players play multimedia contents in different areas of a program, synchronous playing of multiple players needs to be ensured in order to ensure accuracy of playing pictures.
More specifically, when different areas of the program content are allocated to different players according to the slicing information, the following manner may be adopted.
That is, different areas of the program content and program resolutions corresponding to the different areas of the program content are first determined based on the slicing information. And then, matching the picture output resolution of each player with the resolution of each program one by one, and correspondingly distributing different areas of the program content to different players according to the matching relation.
For example, referring to fig. 7, when the server side makes a program, the program resolution is input, and at the same time, the frame output resolution of the player is input. Such as: the program resolution is 11520 × 1080, since the player output maximum resolution is 3840 × 2160 and the picture output resolution is 3840 × 1080, here, it will be understood by those skilled in the art that the player resolution includes the output maximum resolution and the picture output resolution. Therefore, when different areas of the program content are divided into the players, the resolutions of the corresponding different areas can be determined based on the multimedia content loaded in each sub canvas in the segmentation information, then the picture output resolutions of the players are matched with the program resolutions corresponding to the different areas one by one, and the different areas of the program content (i.e. corresponding to each program canvas in the whole canvas) are distributed into different players according to the matching relationship.
After the program distribution is finished, the accurate and complete display of the program content can be ensured only by controlling the players to play simultaneously. Therefore, in a possible implementation manner, when the players are controlled to synchronously play different areas of the program content respectively, a synchronization mechanism can be adopted to implement.
Namely, a main player is determined by each player, and the playing time of the main player is monitored in real time. Meanwhile, the playing time of the main player is used as the reference time, and the other players except the main player in the players are controlled to play the corresponding program content according to the reference time.
For example, referring to fig. 8, a first player is used as a master device, a playing program or a switching program is used as a reference time, and other players are used as slave devices, and the latest playing time of the master device is automatically obtained through a program synchronization service to implement synchronous playing of multimedia information across terminals.
It should be noted that, in order to ensure the continuity, stability and smoothness of playing the program content, the playing time of each player allows a minimum error. That is, when the playing time of the main player is used as the reference time and the other players in the players except the main player are controlled to play the corresponding program content according to the reference time, the error between the playing time of the other players except the main player and the reference time should be less than or equal to 1 millisecond.
In addition, it should be noted that, in the method for publishing the multimedia information irregular screen according to the embodiment of the present application, when the set program resolution is smaller than the preset resolution, the application scene may be adapted to a smaller display device. Such as: a square display device, a diamond display device, a polygonal display device, or other specially shaped display device. In this case, when the server side makes a program, the currently required program resolution may be directly input, and a corresponding program canvas may be set according to the input program resolution. The program canvas can be understood as a virtual screen display range and can also be considered as a screen for playing an actual program, corresponding multimedia content is directly loaded on the program canvas after the setting of the program canvas is completed, the manufactured program content is directly sent to a player of a client after the loading is completed, the program content and the program resolution of the program content are read by the player, the dynamic adjustment of the picture output resolution is carried out according to the read program resolution, the point-to-point playing of the program and the output display is realized, and the effect that the program is seen and answered in the program manufacturing is finally achieved.
In order to more clearly illustrate the set program canvas mode when the program resolution is smaller than the preset resolution, the following three embodiments are exemplified. The predetermined resolution is 1920 × 1080. Referring to fig. 9a to 9c, the program resolutions are set as: 1920 × 1080, 500 × 500 and 1920 × 300, the layout of the set program canvas.
When the server side makes the program content, the program resolution of the program content is defined by user, and the corresponding program canvas is automatically set according to the defined program resolution, so that the finally made program content can be highly matched with the display screen of the client side, the effect of indiscriminate display of the program content can be finally realized, and the personalized requirements of users can be met.
