It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
First, some terms referred to in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
Bullet screen: refers to a commentary subtitle that pops up when multimedia is viewed over a network. In the process of watching multimedia, the user can watch the barrage published by other users and can also send the barrage, and the sent barrage can also be seen by other users, so that the interaction in the process of watching multimedia is realized.
Multimedia: a medium refers to a carrier that carries or transports some information or substance. In the computer field, media are mainly carriers for transmitting and storing information, wherein transmitted information includes voice, text, data, video, audio, and the like. Carriers for storing information include hard disks, floppy disks, magnetic tape, magnetic disks, optical disks, and the like.

The position of the playing progress mark: a marker bit for indicating how long the multimedia content has been played. For example, the mark position on the playing progress time axis is determined according to the played time length of the multimedia content, the total playing time length and the total length of the playing progress time axis.
The playing time point position: is determined according to the playing time length of the corresponding multimedia content when the barrage is released. The positions of the playing time points are distributed along the playing progress at intervals.
And (3) carrying out cycle display in sequence: and displaying the target objects from beginning to end according to the arrangement sequence of the target objects, and displaying the target objects from beginning again after the last target object is displayed. In the embodiment of the application, the bullet screens are displayed in sequence according to the sequence after the bullet screens are sequenced, and after the last bullet screen is displayed, the bullet screens are displayed from the beginning. For example, the release time T of each barrage is { T1, T2, … …, tn }, and the multimedia application displays the corresponding barrages at a constant speed in the order of the release time from morning to evening. And when the bullet screen corresponding to tn is displayed, displaying each bullet screen from the beginning. t is the release time, and n is the total number of bullet screens.
The design concept of the embodiment of the present application is described below.
With the development of internet technology, people increasingly like to open barrages when watching dramas, movies and listening to music on the internet, and enjoy the fun brought by the interactive experience. The user can see many interesting whistling languages through the barrage, as well as comments on the highlight.
In the related art, when a bullet screen of a played multimedia is displayed, the following two methods are generally adopted:
the first mode is as follows: and sequentially displaying a plurality of bullet screens of the played multimedia according to the sequence of the release time of the bullet screens.
By adopting the method, all the barrages can be seen when the multimedia is not played, but the user cannot determine the playing time of the corresponding multimedia content when the barrages are published.
The second way is: and storing each bullet screen and the playing time length of the multimedia content when the bullet screen is released in an associated mode, and displaying the associated bullet screen according to the playing time length of the current multimedia content of the multimedia content when the multimedia content is played.
By adopting the method, the playing duration of the corresponding multimedia content can be determined when the barrage is released, but before the multimedia playing is finished, a user cannot see all the barrages and cannot know the highlights of the unviewed multimedia content.
Obviously, the conventional technology does not provide a technical solution that can see all barrages before the end of multimedia playing and can determine the playing duration of the multimedia content when each barrage is released, so a technical solution for controlling the playing of the multimedia content is urgently needed, and the display mode of the barrages is optimized when the multimedia is played.
In view of the above analysis and consideration, the present application provides a playing control scheme for multimedia content, in which a playing time point position matched with each bullet screen is determined according to a playing duration of the corresponding multimedia content when the bullet screen is released, and the bullet screens matched with the playing time point positions are respectively displayed at playing time points distributed along a playing progress interval when the multimedia content is played.
To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide method steps as shown in the following embodiments or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed in the order of the embodiments or the method shown in the drawings or in parallel in the actual process or the control device.
Fig. 1 is a schematic diagram of a multimedia content playing control system. The system includes a server 101 and a control device 102.
Wherein the control device 102 has a multimedia application installed therein. The multimedia application acquires multimedia content and each barrage through the server 101, and when the multimedia is played, the barrages matched with the playing time points can be respectively displayed at the playing time points distributed at intervals along the playing progress.
Optionally, the playing progress may be represented by a playing progress timeline, that is, a playing progress bar of the application, or may be represented in other forms, which is not described herein again.
In one embodiment, the multimedia application determines the bullet screen display sequence of each playing time point position according to the acquired release time of each bullet screen, and sequentially and circularly displays the corresponding bullet screens at each playing time point position according to the bullet screen display sequence and the set speed.
And the playing time point position matched with each bullet screen is determined according to the playing time length of the corresponding multimedia content when the bullet screen is published. The playing time length of the multimedia content is determined by the playing time length of the multimedia. The playing time point position may be determined by the multimedia application in the control device 102 according to the playing time length of the corresponding multimedia content when the bullet screen is released, or may be obtained by the server 101.
Multimedia refers to a carrier carrying and transmitting some information or substance, and multimedia content can be audio, video, and the like. It should be noted that the multimedia content may be a single video, or may be a plurality of short videos or a series of pictures, such as a video obtained by combining a plurality of short videos, or a combination of a plurality of pictures.
Therefore, when the multimedia content is played, each bullet screen can be continuously displayed, and the playing time of the corresponding multimedia content when the bullet screen is published can be determined, so that a user can know various highlights of the multimedia content when the multimedia content is played at the beginning, and partial predictability is provided for the unviewed multimedia content.
And before the playing control of the multimedia content, the playing time point position matched with each bullet screen is predetermined. The execution subject may be a server or a multimedia application in the control device. Fig. 2 shows a flow chart of an implementation of the play time point position determination.
Step 200: and acquiring the playing duration of the corresponding multimedia content when each bullet screen is issued.
Specifically, in an embodiment, when receiving a multimedia playing request sent by a multimedia application, a server determines requested multimedia content, obtains each barrage of the multimedia content, and a playing duration of the corresponding multimedia content when each barrage is released.
In one embodiment, the control device sends a multimedia playing request to the server and receives the playing duration of the corresponding multimedia content when each barrage returned by the server is issued.
Before step 200 is executed, when the user issues the barrage through the multimedia application, the multimedia application obtains the playing duration of the multimedia content when the barrage is issued, and sends the barrage and the playing duration of the corresponding multimedia content when the barrage is issued to the server. And the server stores the received barrage, the played time length of the multimedia content and the played multimedia content in an associated manner.
Therefore, the server acquires the stored playing time of the multimedia content corresponding to each barrage, or the control device acquires the playing time of the multimedia content corresponding to each barrage through the server.
Step 201: and determining the corresponding playing time point position of the bullet screen according to the playing duration of the corresponding multimedia content when the received bullet screen is issued.
Specifically, when step 201 is executed, the following steps may be adopted:
s2011: and removing the duplication of the plurality of barrages according to the playing duration of the multimedia contents of the plurality of barrages to obtain the total number of the barrage marks after the duplication is removed.
For example, if the played time length of the multimedia content of the bullet screen a is 10s, the corresponding playing progress mark position is K1, the played time length of the multimedia content of the bullet screen B is 15s, the corresponding playing progress mark position is K2, the played time length of the multimedia content of the bullet screen C is 10s, and the corresponding playing progress mark position is K1, the total number of bullet screen marks is determined to be 2.
The playing duration of each multimedia content corresponds to one playing progress mark position, when the playing durations of the multimedia contents are the same, the corresponding playing progress mark positions are overlapped, and the total number of the displayed playing progress mark positions can be counted through duplication elimination.
S2012: and determining the playing time point position matched with each bullet screen according to the total number of the bullet screen marks and the playing duration of the multimedia content of each bullet screen.
Specifically, S2012 is executed, and the following two ways can be adopted:
the first mode is as follows: and when the total number of the bullet screen marks is not higher than the preset mark number, determining the playing progress mark position corresponding to each bullet screen according to the playing duration of the multimedia content corresponding to each bullet screen, and determining the playing progress mark position corresponding to each bullet screen as the matched playing time point position.
That is, when the number of the playing progress mark positions is small, the playing progress mark position of the bullet screen is directly determined as the playing time point position.
In practical applications, the number of the preset marks is set according to practical application scenarios, for example, the number of the preset marks is 10, and is not limited herein.
For example, let b be the bullet screen, n be the total number of bullet screens, and m be the number of playing time point positions. The set of multiple barrages of multimedia content C ═ { b1, b2, … …, bn }, and the set of barrages matched at each play time point position is C1, C2, … …, Cm, i.e., C ═ C1 ═ C2 ═ … … ═ ucm.
The second way is: when the total number of the bullet screen marks is higher than the preset mark number, the playing progress mark position corresponding to each bullet screen is determined according to the playing duration of the multimedia content corresponding to each bullet screen, the minimum distance of the distance between each playing progress mark position and the multiple set mark positions is determined, and the set mark position corresponding to the minimum distance of each bullet screen is determined as the corresponding playing time point position.
In one embodiment, when the total number of bullet screen marks is higher than the preset number of marks, the following steps are performed for each bullet screen:
and determining corresponding playing progress mark positions according to the playing duration of the multimedia content corresponding to the bullet screen, determining the distance between each playing progress mark position and each set mark position, and determining the set mark position corresponding to the minimum distance in the distances as the playing time point position matched with the bullet screen.
That is, the setting mark position where the bullet screen is closest to the user is determined as the play time point position of the bullet screen.
For example, referring to fig. 3a, a bullet screen clustering diagram is shown. The play time point position where the play progress mark position a1 and the play progress mark position a2 match is the set mark position H1. The play time point position where the play progress mark position A3 and the play progress mark position a4 match is the set mark position H2. The play time point position where the play progress mark position a5 and the play progress mark position a6 match is the set mark position H3.
The setting mark positions are distributed along the playing progress interval and are initial positions of the playing time point position. Thus, a plurality of bullet screens can be assigned to the nearest set mark position.
In one embodiment, the playing progress of the multimedia content is divided according to the number of preset marks, and a plurality of set mark positions are obtained.
Optionally, when determining the position of the play progress mark, the following formula may be adopted:
Pj＝L/(m+1)*j；
wherein, Pj is the jth set mark position, L is the total length of the time axis of the playing progress, m is the number of the preset marks, and j is an integer.
For example, the participation of fig. 3b is a schematic diagram of the playing progress. Three set flag positions are included, namely set flag position H1, set flag position H2, and set flag position H3.
That is, a plurality of setting mark positions of the preset mark number are uniformly distributed along the playing progress. Thus, the positions of the plurality of setting marks can be uniformly distributed on the time axis of the playing progress at equal intervals. In practical applications, the positions of the multiple preset marks with the preset number may also be distributed along the playing progress in other manners, which is not described herein again.
Further, for each playing time point position obtained by the second method, the playing time point position may be updated according to the playing duration of the multimedia content of the plurality of barrages matched with the playing time point position.
That is, the average value of the playing progress mark positions of the plurality of barrages matched with each playing time point position is respectively determined, and the corresponding playing time point position is updated according to the average value corresponding to the playing time point position.
Specifically, when the playing time point position is updated, the following steps may be adopted:
s2013: and respectively determining the summation of the playing progress mark positions of the plurality of bullet screens matched with each playing time point position.
Specifically, the sum of the playing progress mark positions of the plurality of barrages matched with each playing time point position is calculated respectively.
S2014: and respectively determining the display quantity of the plurality of bullet screens matched with each playing time point position.
Specifically, for each playing time point position, the number of the bullet screens matched with the playing time point position is counted to obtain the display number.
S2015: and aiming at the playing time point position of which the adding and displaying quantity meets the preset updating condition, updating the corresponding playing time point position according to the adding and displaying quantity corresponding to the playing time point position. The updated playing time point position is positively correlated with the summation and negatively correlated with the display quantity.
Optionally, when S2015 is executed, the following steps may be executed for each play time point position respectively:
and determining the ratio between the sum of the playing time point positions and the display quantity, and updating the playing time point position to the ratio when the absolute value of the difference between the ratio and the playing time point position is lower than a preset convergence value.
When the updated playing time point position is determined, the following formula may be adopted:
Figure BDA0002355598170000131
wherein Pj is the updated jth playing time point position, x is the playing progress mark position of the barrage, Bj＝{x1，x2，x3，……xnAnd n is a positive integer. I BjAnd | represents the number of presentations.
For example, referring to FIG. 3c, an exemplary diagram of program code for playing point location determination is shown. In fig. 3c, pj is the jth playing time point position, the initial value of pj is the set mark position, xi is the playing progress mark position of the ith bullet screen, i is the serial number of the bullet screen, j is the playing time point position serial number, n is the number of the bullet screens, m is the number of the playing time point positions, epsilon is the preset convergence value, and i, j, m, and n are positive integers.
As can be seen from fig. 3c, for each bullet screen, the distance between the playing progress mark position xi of the bullet screen and each playing time point position is determined, the bullet screen is allocated to the playing time point position pj closest to the playing time point position, and the ratio between the sum of the playing time point positions of the playing time point position pj and the corresponding display number is updated to the new playing time point position pj. Then, an absolute value diff of a difference between the play time point position pj before updating and the play time point position pj after updating is calculated, and when diff < epsilon, the play time point position pj after updating is output.

Figure BDA0002355598170000141
Because the quantity of broadcast time point position is when more, the broadcast time point position that shows in the screen can be comparatively intensive, and the user is difficult to distinguish a plurality of broadcast time point positions, consequently, in this application embodiment, when bullet curtain mark total number is less, with the broadcast progress mark position of a plurality of bullet curtains, directly confirm for the broadcast time point position of matching, otherwise, confirm a plurality of bullet curtain distance nearest settlement mark position as the broadcast time point position of matching.
In one embodiment, when a multimedia playing request sent by a multimedia application is received, a server returns a multimedia file containing playing time points of a plurality of barrages to the multimedia application based on the multimedia playing request, so that the multimedia application respectively displays the barrages matched with the playing time points at the playing time points according to the multimedia file.
Therefore, after the playing time point positions matched with the plurality of barrages are obtained, the barrages matched with the playing time point positions can be displayed at the plurality of playing time point positions through multimedia application.
