detailed description

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with aspects of the invention as detailed in the appended claims.

FIG. 1 is a schematic diagram of a scenario according to an embodiment of the present invention. FIG. 1 includes: a server 21 and a plurality of clients, such as a client 11 and a client 12. The client may be a common electronic device with a display, such as : a desktop computer, a notebook computer, a smart TV or a tablet computer, etc., each client is connected to the server 21 via the network 31, and the client and the server 21 can transmit data through the network, and the network 31 can be a wired network, for example : Optical network, etc., can also be a wireless network, such as Wifi.

When the server 21 is a video live server, the server 21 may send live video data to the client, and the client may play the live video locally. In addition, in order to increase the user's participation, the client can also collect the barrage information input by the user, and send the barrage information to the server 21 through the network, and then the server 21 sends the barrage information to each client, so that all When the client plays the video, it can display the information of the barrage collected in different clients.

FIG. 2 is a schematic flowchart diagram of a video review control method according to an embodiment of the present invention.

In the embodiment of the present invention, the method can be applied to the server 21 in FIG. 1. As shown in FIG. 2, the video review control method can include the following steps.

S101. Obtain a barrage information sent by at least one client during a live broadcast.

In the embodiment of the present invention, the barrage information may include: a barrage content and a barrage release time, wherein the barrage content may be information input by the user in the client for commenting on the currently played video, and the barrage The content may include one or more of characters, pictures, and voices. The time when the barrage is published refers to the time when the user releases the barrage, which may be the system time, for example, the time in the client or the server, or may be played for the video. In the embodiment of the present invention, in order to match the content of the barrage and the video plot, the barrage release time is selected as the time of the video play.

S102. Determine whether the barrage information meets a preset playback condition.

Since the content of the barrage in the barrage information is usually the content of the user's comment on the video plot, when the user misses a certain lens or is interested in a certain lens, the content of the barrage is often used to express emotions, for example: The played footage is commented or sentimental, etc., so it can be passed through the barrage The analysis is performed to determine if the user wishes to look back at the played shot.

In the embodiment of the present invention, the preset playback condition may be used for statistics on specific words, symbols, or pictures in the content of the barrage, for example, statistics may be counted by counting the number of times of "looking back" appearing in the content of the barrage. When there are more than 50 in 1 minute, then it can be considered that the preset playback condition is satisfied. In a specific application, the preset playback conditions may be set according to the background controller, or may be set according to the content selected by the user.

When the barrage information satisfies the preset playback condition, step S103 is performed; otherwise, the process returns to step S101 to continuously acquire the barrage information.

S103. Determine a target playback video corresponding to the barrage information.

When it is determined in step S102 that the barrage information satisfies the preset playback condition, only the condition indicating the playback is triggered, but the specific playback of the video and how to play back need to be separately set.

In the embodiment of the present invention, the target playback video that needs to be played back can be determined by analyzing the information of the barrage, and is also described by the example in step S102. In the information of the barrage that meets the preset playback condition, the information can be found. The first one contains the content of the barrage with the word "playback", and then the first bar is the playback start time corresponding to the barrage content containing the word "playback", and then the playback time is followed. 5 minutes as the playback cut-off time, and also the 5 minute video as the target playback video.

S104. Send the target playback video to the at least one client.

After determining the target playback video, the server 21 may directly send the target playback video to the client, so that the client displays the screen of the target playback video.

In the embodiment of the present invention, step S104 may adopt the following manner:

And uploading the superimposed video to the at least one client for playing.

In this way, when the client is playing, the playback video is also displayed in the form of picture-in-picture.

In addition, in step S104, the screen of the target playback video and the screen of the live video may be sent to the at least one client independently for playing, so that when the client receives two independent video images When the client can choose to split the two video screens by screen, and also click on a certain playback video screen to zoom in and watch the playback video separately.

The above-described example of step S104 is merely illustrative and should not be construed as limiting the invention.

In a specific application, when the target playback video is sent, it can be sent to all clients watching the live broadcast, that is, globally. In addition, some conditions can be added, for example, it can be sent only to a specific smart TV, or only to users with member rights.

The video review control method provided by the embodiment of the present invention obtains at least one of the live broadcast processes The barrage information sent by the client, and then analyzes the barrage information to determine whether the barrage information satisfies the preset playback condition. When the barrage information satisfies the preset playback condition, the target playback video to be played is determined, and the target playback video is played. Send it to the client for display, so that the user can watch the live video at the same time while watching the live video on the client.

The method can automatically match the preset playback conditions according to the barrage information input by the user during the live broadcast of the video. Once the barrage information is determined to meet the preset playback conditions, the target playback video can be automatically determined and presented to the client. The live playback video transmits the target playback video to the client at the same time, and the playback process of the entire playback video does not require the user to perform separate playback control, and does not require any playback control of the background operator.

In addition, since the user-entered barrage content is a user's comment on the live video episode, the use of the barrage content to control the playback can also improve the playback accuracy of the highlight moment. In addition, when users understand the function, they will be more willing to participate in the barrage interaction, and can also improve the user's enthusiasm for using the barrage to communicate.

In another embodiment of the present invention, as shown in FIG. 3, step S102 shown in FIG. 1 may include the following steps.

S201: Determine whether the content of the barrage in the barrage information includes a preset word;

When the user misses the exciting moment, he or she often enters "too good", "too wonderful", or "pity, but also wants to look at it again" and other comments, so in the embodiment of the present invention, the preset words It can be a specific text, for example, one or more combinations of "review", "replay", "exciting", "pity", "like", of course, in other embodiments, preset words It can also be analyzed according to the habits of the user when watching the video, so that the selection of the preset words is more accurate.

In the embodiment of the present invention, S201 may include the following steps:

S1: Identifying the content of the barrage in the barrage information to obtain a recognition result;

When the content of the barrage is text, it is identified by means of text recognition, etc., and when the content of the barrage is a picture, it can be identified by means of image recognition or the like.

S2: determining whether there is a word matching the predicted word in the recognition result;

When there is only one preset word, the matching may refer to whether it is completely the same, that is, the matching degree is 100%; when there are multiple preset words, the matching may also mean that the number of recognized result words exceeds the preset quantity, that is, the matching degree Can be less than 100%, for example: 80% or more, etc.;

S3: When there is a word matching the predicted word in the recognition result, determining that the barrage content includes a preset word.

When the preset content is included in the content of the barrage, step S202 is performed; otherwise, the process is ended.

S202. Count the number of the contents of the barrage content including the preset words in the preset time interval according to the barrage release time.

Normally, global playback or playback to a certain part of the user is not performed for one user's comments, and whether or not playback is performed based on feedback from multiple users. Whether the reaction needs to be played back or not, a very important condition is that a plurality of users have the demand at the same time in a short time, that is, the demand density. Therefore, in this step, all the preset time intervals can be counted as the barrage containing the preset words. The number of contents is used as a basis for judgment.

S203. Determine whether the number of the statistics obtained exceeds a preset threshold.

The preset number of thresholds can be set according to the samples collected in the actual application.

When the number of the statistics obtained exceeds the preset number threshold, step S204 is performed; otherwise, the process ends.

S204. Determine that the barrage information meets a preset playback condition.

For example, in any one minute of video playback, it is judged whether there is more than 50 comments of "like" word. If it appears, it means that the user thinks that the video within three minutes is very exciting, and then it is determined that the three-minute video may need to be played back. a bit.

The method provided by the embodiment of the present invention can accurately determine whether video playback is required by analyzing the words appearing in the content of the barrage in the barrage information and the density of the content of the barrage content. The accuracy of video playback can be improved, so that the user can quickly and timely enjoy the playback video after evaluating the wonderful story.

In another embodiment of the present invention, as shown in FIG. 4, the foregoing step S103 in FIG. 2 may include the following steps.

Each barrage information has a corresponding barrage release time. By comparing the barrage release time, the first barrage information can be found.

S302. Determine a barrage release time corresponding to the first barrage information as a playback start time.

Taking the case mentioned in the embodiment shown in FIG. 3 as an example, when the comment of the word "Like" exceeds 50 times in one minute of video playback, it is considered that the preset playback condition is satisfied, that is, the one minute. The video is more exciting, then in the embodiment of the present invention, the first content of the barrage containing the word "Like" can be extracted, and the first release time of the barrage corresponding to the content of the "Lan" word barrage can be determined. For the playback start time.

S303. Determine, in the first preset time period after the playback start time, the video as the target. Standard playback video.

Normally, the playback video will not be a long video. Therefore, after determining the playback start time, the video in the first preset time period after the playback start time can be uniformly determined as the video to be played back. A preset time period can be 1 minute, 2 minutes, and the like.

The method provided by the embodiment of the present invention uses the first barr information in the barrage information that satisfies the preset playback condition as the playback start time of the playback video, and uses the video of the content of the first preset time period after the time as The target playback video, although the setting of the first preset time period may exceed the wonderful lens, since the starting time is accurate, the integrity of the playback video can be maximized, and the problem that the user still misses the wonderful lens by looking back can be avoided.

In another embodiment of the present invention, as shown in FIG. 5, the foregoing step S103 in FIG. 2 may include the following steps.

S401. Extract the last barrage information from all the statistics of the preset number of thresholds in chronological order.

Each barrage information has a corresponding barrage release time. By comparing the barrage release time, the last barrage information can be found.

S402: Determine a barrage release time corresponding to the last barr information as a playback cutoff time;

Taking the case mentioned in the embodiment shown in FIG. 3 as an example, when the comment of the word "Like" exceeds 50 times in one minute of video playback, it is considered that the preset playback condition is satisfied, that is, the one minute. The video is more exciting, then in the embodiment of the present invention, the last content of the barrage containing the word "Like" can be extracted, and the last release time of the barrage corresponding to the content of the "Lan" word barrage is determined as playback. Deadline.

S403: Determine a video in the second preset time period before the playback cutoff time as the target playback video.

Normally, the playback video will not be a long video. Therefore, after determining the playback cut-off time, the video in the second preset time period after the playback cut-off time can be uniformly determined as the video to be played back. The time period can be 1 minute, 2 minutes, and the like.

According to the method provided by the embodiment of the present invention, the last barr information in the barrage information that satisfies the preset playback condition is used as the playback cutoff time of the playback video, and the video of the content of the second preset time period before the time is used as the target playback. Video, although the setting of the second preset time period may exceed the wonderful shot, since the deadline is accurate, the integrity of the playback video can be maximized, and the problem that the user still misses the wonderful shot by looking back can be avoided.
