It is understood that the adaptable scene of the embodiment of the present disclosure: during live streaming, viewer end can receive two numbers According to a circuit-switched data can be live video data, and another circuit-switched data can be broadcast information to be synchronized.In live video data with The associated video frame of broadcast information to be synchronized need to be played simultaneously with broadcast information to be synchronized.Wherein, broadcast information to be synchronized and straight Broadcasting an at least frame video frame in video data, there are incidence relations.Exist for example, incidence relation can be in live video data Broadcast the video frame of broadcast information to be synchronized.In addition, broadcast information to be synchronized can be problem topic, answer statistical result, to Sell merchandise news, to data such as recall infos, it is numerous to list herein.

In one embodiment, live video data distribution and broadcast information to be synchronized can be realized by the same server Distribution.As described in Fig. 1 a, Fig. 1 a is the schematic diagram of a scenario of synchronizing information play system provided in an embodiment of the present invention.In the scene In, it may include main broadcaster end, server and viewer end, first information simultaneously playing device is integrated in viewer end, the second information Simultaneously playing device is integrated in server.It is understood that the scene is illustrated by taking a viewer end as an example, in fact, Viewer end can be one or more.

Main broadcaster end can be video data originating end, and user terminal can be video data receiving end, in certain scenes, main broadcaster End is properly termed as presiding over end, and viewer end is properly termed as user terminal.Main broadcaster end and viewer end, which can be, to be mounted on an electronic device Software, be also possible to terminal device.Main broadcaster end can call the methods of camera recorded video, shooting photo production live streaming number According to being then sent to server by network；Viewer end and main broadcaster end can be by the interactive messages (such as: barrage message) of input It is sent to server, interactive message can be played at each end of same direct broadcasting room by realizing.And it is directed to broadcast information to be synchronized, it is past Toward being to be sent to server by main broadcaster end, each viewer end is issued by server.Server is used to provide internet live streaming Background service, such as the corresponding relationship at main broadcaster end and viewer end is saved, and be broadcast live distribution and the interactive message of data Distribution and the distribution of broadcast information to be synchronized etc..In one embodiment, each straight in order to be adapted to the video data received Platform, various different agreements are broadcast, the video data received can be transcoded into server and support such as PTMP, HLS, FLV Format draws for corresponding viewer end to flow.

In another embodiment, in order to distinguish different business and improve the timeliness of information processing, server can be with Including Video Distribution Server and live streaming platform service server etc., Video Distribution Server can be used for carrying out point of video flowing Hair, live streaming platform service server are used to carry out the distribution of data, the distribution of broadcast information especially to be synchronized.It is understood that It is that according to actual needs, server can also include that the present for distributing the barrage server of barrage, for distributing present takes Business device etc., will not repeat them here.

For example, Fig. 1 b is another scene signal of synchronizing information play system provided in an embodiment of the present invention with reference to Fig. 1 b Figure.It in this scenario, may include main broadcaster end, first server (Video Distribution Server), second server (live streaming platform industry Business server) and viewer end, first information simultaneously playing device be integrated in viewer end, the second synchronizing information playing device is integrated in In first server and second server.

When needing to send video data to first server, main broadcaster end is collected video frame according to the frame per second of video Corresponding timestamp is added, is retransmited to first server, then is sent video data to viewer end by first server；Work as touching When sending out broadcast information to be synchronized and sending instruction, main broadcaster end is that broadcast information to be synchronized adds corresponding timestamp, is retransmited to the Two servers, then the broadcast information to be synchronized for carrying timestamp is sent to viewer end by second server.Wherein, to the second clothes When business device issues broadcast information to be synchronized, the video frame currently generated is determined as associated video frame.Due to be synchronized in transmission When broadcast information, positive generation and the associated video frame of broadcast information to be synchronized, that is, being at this time broadcast information to be synchronized addition Timestamp is corresponding with timestamp added by the video frame at this time for acquisition.Therefore, the video frame currently generated be with to same Walk the related video frame of broadcast information.Therefore, when viewer end synchronizes operation, video frame can be compared by viewer end The timestamp of timestamp and broadcast information to be synchronized, when the time difference between the two reaching minimum threshold, in the broadcasting of video Broadcast information to be synchronized is played in picture, to improve the broadcasting synchronism of associated video frame Yu broadcast information to be synchronized.

It is illustrated individually below.

The present embodiment will be described from the angle of first information simultaneously playing device, which can be with It is integrated in viewer end, as illustrated in figure 1 c, the detailed process of the method for the present embodiment can be such that

101, the video data that first server is sent is received, and the video data is played out, the video counts According to the video frame for including carrying timestamp.

Wherein, video data can be with main broadcaster end by calling camera recorded video, shooting photo, can also be directly from sound Video acquisition end obtains audio, video data etc., and makes acquisition video data.In one embodiment, in order to reach audio and video It is synchronous, audio data and image data can be synthesized, and guarantees with main broadcaster end after obtaining audio data and image data Audio data is synchronous with image data, leads to picture and the nonsynchronous situation of audio to avoid transmission process.

Wherein, video data is made of multiple video frames, and timestamp is added according to the frame per second of video, than Such as, a timestamp is added every two frames.

Wherein it is possible to can be broadcast to video frame using the mode that receiving while plays when receiving video frame It puts.

102, when the needs for receiving second server transmission are believed with the broadcasting to be synchronized that the video data synchronization plays When breath, the timestamp of the broadcast information to be synchronized is extracted.

Wherein, broadcast information to be synchronized carries corresponding timestamp, the timestamp and view of the broadcast information to be synchronized Frequency timestamp entrained by an at least frame associated video frame in is corresponding.

Specifically, broadcasting letter to be synchronized can be extracted when receiving the broadcast information to be synchronized of second server transmission The timestamp of broadcast information to be synchronized can be compared by the timestamp of breath so as to subsequent with the timestamp of video frame, thus It can be treated according to comparison result and information is played simultaneously play out.

Wherein, broadcast information to be synchronized can be that there are the letters of incidence relation with an at least frame video frame in video data Breath.For example, incidence relation can be the video frame for existing in video data and broadcasting broadcast information to be synchronized.It is divided by type to same Broadcast information is walked, broadcast information to be synchronized can be character information, image information, audio-frequency information, video information etc..It is drawn by content Divide broadcast information to be synchronized, broadcast information to be synchronized can be problem topic, answer statistical result, goods for sale information etc..

Such as during live streaming, host can broadcast the broadcast information to be synchronized.So-called casting broadcasting letter to be synchronized Breath is broadcasted broadcast information to be synchronized and be can be and read to be synchronized broadcast if broadcast information to be synchronized is character information or image information The particular content for putting information is also possible to read the instruction information for being used to indicate broadcast information to be synchronized；If broadcasting letter to be synchronized Breath is character information, image information, audio-frequency information or video information, broadcasts broadcast information to be synchronized and can be and plays to be synchronized broadcast Information is put, information is played simultaneously is introduced at the same time it can also treat.Wherein, it plays and is not limited to playing audio-video, can also wrap Include broadcast information.By taking broadcast information to be synchronized is problem topic as an example, in one example, host can broadcast problem topic Particular content, such as: what animal Chinese national treasure is, or even can also broadcast answer choice, such as: A, kangaroo；B, panda； C, penguin.

103, the timestamp of newest video frame is extracted, wherein the newest video frame is in the video frame being currently received Nearest apart from current time and carrying timestamp video frame.

Wherein, newest video frame is nearest apart from current time in currently received video frame, and carries timestamp Video frame.For example, current time is 10:00,5 video frames are had received before this, receiving time is respectively 9:51,9: 53,9:55,9:57,9:59, wherein the video frame that only 9:53 and 9:57 are received carries timestamp, then, newest video frame It is then this video frame that 9:57 is received.

When needing to extract the timestamp of newest video frame, can from the video frame being currently received selected distance it is current Time is nearest, and carries the video frame of timestamp as newest video frame, then extract the timestamp of newest video frame, so as to The timestamp of broadcast information to be synchronized is compared, and information is played simultaneously plays out so as to be treated according to comparison result.

104, the time between the timestamp of the newest video frame and the timestamp of the broadcast information to be synchronized is obtained Difference.

Wherein, since broadcast information to be synchronized is by signalling, and the real-time of signalling compares video data The real-time of transmission is high.Therefore video frame and broadcast information to be synchronized that synchronization is sent, broadcast information to be synchronized can arrive first It reaches, therefore the video frame and broadcast information to be synchronized that synchronization reaches, the timestamp of broadcast information to be synchronized is than video frame Timestamp is big, i.e., the timestamp of broadcast information to be synchronized is greater than the timestamp of newest video frame.

For example, timestamp is added according to sending instant.For example, 9:51 simultaneously have sent information to be played and be associated with regard Frequency frame, it is to be synchronized since the real-time of the information to be played by signalling is higher than the real-time of video data transmission Broadcast information can first be reached than associated video frame.Therefore, the video frame reached with broadcast information synchronization to be synchronized is not to close Join video frame, i.e. the timestamp of the video frame of synchronization arrival can be less than the timestamp of broadcast information to be synchronized, i.e., currently arrive The timestamp of the video frame reached is all less than the timestamp of broadcast information to be synchronized.

Specifically, the timestamp of broadcast information to be synchronized and the timestamp of newest video frame can be subtracted each other, obtain to same Walk the time difference between the timestamp of broadcast information and the timestamp of newest video frame.

105, the play time of the broadcast information to be synchronized is determined according to the time difference, and according to the play time Play the broadcast information to be synchronized.

Wherein, since the video frame that the broadcast information to be synchronized that synchronization is sent can be sent than synchronization first reaches, Therefore, the key for being aligned associated video frame and broadcast information to be synchronized is exactly that broadcast information to be synchronized reaches the view to be associated such as later Frequency frame for a period of time, guarantees that the time difference between the two is sufficiently small.It therefore, can be to be synchronized to play by setting minimum threshold Broadcast information, but the timestamp that video data transmission Caton may be caused to make video frame due to network difference can not timely update, Cause the time difference of the two timestamp infinitely great, so need to be arranged a max-thresholds, when the time difference being greater than max-thresholds, Broadcast information to be synchronized only waits the duration of max-thresholds.

Specifically, the time difference can be compared with the first preset duration and the second preset duration, tied further according to comparing Fruit determines the play time of broadcast information to be synchronized, then treats information is played simultaneously plays out further according to play time.

Wherein, the first preset duration is max-thresholds, and the second preset duration is minimum threshold, the first preset duration and second Preset duration can preview data according to existing net and obtain.

In practical applications, such as in live streaming answer scene, user can be forbidden to submit before host announces answer Answer, it is contemplated that the fairness of topic time of occurrence between network and user needs that an answer deadline is arranged on backstage, Provide user's residue Reaction time.After topic arrival, need with from the background to remaining Reaction time subtract and need stand by tone The time of audio video synchronization obtains the playing duration of topic.Due to network problem, it is possible that topic is reached than later, video Data transmission card or cutout, if topic just plays out after being simply waiting max-thresholds at this time, it is possible that user Remaining Reaction time is only left few time, such as 3s or even 1s, and its influences user experience.Therefore, in user's answer Between it is synchronous between, need preferentially to guarantee the Reaction time of user.In the specific implementation process, data can be previewed according to existing net It obtains averagely each user and answers one of topic object time, averagely each user is answered into one of topic object time and is set as leaving user's for Minimum Reaction time, then the real waiting time is that the remaining Reaction time that backstage is given subtracts the minimum Reaction time for leaving user for. Wherein, the remaining Reaction time given from the background starts counting after receiving topic from viewer end, and the remaining Reaction time given from the background can In the light of actual conditions to set.

Therefore, when the time difference being greater than max-thresholds, need to pay the utmost attention to broadcast information to be synchronized in the broadcasting of viewer end Duration.At this point, the waiting time of broadcast information to be synchronized is not max-thresholds.Wherein, the waiting of broadcast information to be synchronized at this time Shi Changwei maximum waiting time, it can be subtracted by the default playing duration given from the background and preset minimum playing duration and obtain.

Specifically, comparison result can be divided into three kinds of situations:

When the time difference being more than or equal to the first preset duration, belonging to Network Abnormal leads to video data transmission Caton, at this point, Broadcast information to be synchronized plays out after directly waiting maximum waiting time, play minimum playing duration, namely wait maximum etc. Current time after duration is the play time of broadcast information to be synchronized.

When the time difference being less than or equal to the second preset duration, belong to Network Abnormal cause broadcast information to be synchronized reach compared with Evening, at this point, broadcast information to be synchronized is not to wait for directly playing normal play duration namely current time is broadcast information to be synchronized Play time.

When the time difference is less than the first preset duration and is greater than the second preset duration, belongs to normal condition, can set at this time Timer is set, timing waits maximum waiting time.In waiting process, if having received the new video frame for carrying timestamp, The timestamp that new video frame can then be extracted is updated the timestamp of newest video frame, and then updates broadcast information to be synchronized Timestamp and newest video frame timestamp between time difference, and reset timer, timing waits current need The duration of waiting.When the timestamp of newest video frame has update, the step is repeated, until the timestamp of broadcast information to be synchronized Time difference between the timestamp of newest video frame is fixed less than before the update of time stamp of the second preset duration or newest video frame When the time until, terminate the cyclic process.

Wherein, currently need the duration waited can by from the background to default playing duration subtract and preset minimum playing duration The duration that broadcast information to be synchronized has currently waited is subtracted again, i.e., maximum waiting time has subtracted broadcast information to be synchronized currently etc. To duration obtain, when the update of time stamp of newest video frame, currently the waiting time waited is needed also to update therewith.Its In, default playing duration presets minimum playing duration and normal play duration and can preview data by existing net and obtain, can also be with It is set according to actual conditions.

That is, step " determining the play time of the broadcast information to be synchronized according to the time difference " may include:

When the time difference being not less than the first preset duration, waited according to the first waiting time, and waiting At when determine current time be the broadcast information to be synchronized play time；

When the time difference being not more than the second preset duration, determine that current time is broadcasting for the broadcast information to be synchronized Put the time, wherein second preset duration is less than first preset duration.

Step " play time of the broadcast information to be synchronized is determined according to the time difference " can also include:

When the time difference being less than first preset duration and being greater than second preset duration, waited according to first Duration is waited, and detects whether to receive the new video frame for carrying timestamp in waiting process；

If so, the timestamp based on the new video frame is updated the time difference, and according to it is updated when Between difference determine the play time of the broadcast information to be synchronized；

If it is not, then the current time after first waiting time will be waited to be determined as broadcasting for the broadcast information to be synchronized Put the time.

Wherein, the current time after waiting for the first waiting time refers to the time after the first waiting time of waiting, for example, The first waiting time for needing to wait is 10 seconds, and the time started waiting is 9:40:45 (when/point/second), then waiting first etc. Current time after duration is then 9:40:55.The first waiting time at this time is maximum waiting time, can by will after It default playing duration that platform is given and presets minimum playing duration and subtracts each other to obtain.

For example, default playing duration is 20 seconds, presetting minimum playing duration is 7 seconds, then need to wait at this time first Waiting time is then -7 seconds 20 seconds=13 seconds.

It in one embodiment, can be according to new after having received the new video frame for carrying timestamp in waiting process The timestamp of video frame is updated the timestamp of newest video frame, then the timestamp again based on broadcast information to be synchronized with The timestamp of newest video frame is updated the time difference after update.Namely step " the timestamp pair based on the new video frame The time difference is updated " may include:

It is updated according to timestamp of the timestamp of the new video frame to the newest video frame；

Obtain the new time between the timestamp of the broadcast information to be synchronized and the timestamp of newest video frame after update Difference；

The time difference is updated according to the new time difference.

Specifically, the timestamp of new video frame can be replaced to the timestamp of original newest video frame, that is, after updating most The timestamp of new video frame is the timestamp of new video frame.Then, then by the timestamp and new video frame of broadcast information to be synchronized Timestamp subtract each other, obtain the new time difference, the new time difference replaced to the original time difference again later.

Wherein, after updating the time difference between the timestamp of broadcast information to be synchronized and the timestamp of newest video frame, The updated time difference can be compared with the first preset duration, the second preset duration, then be determined according to comparison result The play time that broadcast information to be synchronized is played simultaneously.

It, can be directly true by current time when the updated time difference being not more than the second preset duration in one embodiment It is set to the play time of broadcast information to be synchronized.When the updated time difference is between the first preset duration and the second preset duration When, the duration for currently needing to wait is obtained, is then waited, carries the new of timestamp if having received in waiting process Video frame can then be updated the time difference according to the timestamp of new video frame.That is, step is " according to the updated time Difference determines the target video frame needed with the broadcast information to be synchronized " may include:

When the updated time difference being not more than second preset duration, determine that current time is the broadcasting to be synchronized The play time of information；

When the updated time difference being less than first preset duration and being greater than second preset duration, second is obtained Waiting time；

First waiting time is updated according to second waiting time, and returns to execution and is waited according to first The step of duration is waited.

Specifically, the second waiting time can be replaced for the first waiting time, after update after obtaining for the second waiting time The first waiting time be not maximum waiting time.

Wherein, the second waiting time can be subtracted by the default playing duration given from the background presets minimum playing duration and subtracts again The duration for going broadcast information to be synchronized currently to wait obtains, and is that broadcasting letter to be synchronized can be subtracted by maximum waiting time The duration that breath has currently waited obtains.

Wherein, the duration that broadcast information to be synchronized has currently waited can for broadcast information to be synchronized from reach it is current The duration of waiting.For example, broadcast information to be synchronized has waited 10 seconds from current time is reached, then broadcast information to be synchronized The duration currently waited is then 10 seconds.For example, current waiting time is 10 seconds, maximum waiting time is 20 seconds, then second Waiting time is then -10 seconds 20 seconds=10 seconds.

In one embodiment, when broadcast information to be synchronized is display information, broadcast information to be synchronized can be played On the picture of target video frame.When display, broadcast information to be synchronized can be directly displayed, can also by broadcast information to be synchronized into It is shown again after row processing, to provide the control that can be operated by spectators.It, can be with by taking broadcast information to be synchronized is problem topic as an example Answer frame comprising problem topic is shown on video frame picture.In one embodiment, not only comprising in topic in answer frame Hold, also furnish an answer input control, so that spectators are by inputting answer in answer input control.In another embodiment, in order to Raising is answered efficiency, each option all can be trigger control, when spectators click or touch option, the option conduct that is triggered The answer that spectators submit.

The video data that the present embodiment is sent using first server is received, and the video data is played out, institute Stating video data includes the video frame for carrying timestamp；When the needs and the video data that receive second server transmission are same When walking the broadcast information to be synchronized played, the timestamp of the broadcast information to be synchronized is extracted, the time of newest video frame is extracted Stamp, wherein the newest video frame is nearest apart from current time in the video frame being currently received and carries the view of timestamp Frequency frame；Obtain the time difference between the timestamp of the newest video frame and the timestamp of the broadcast information to be synchronized；According to The time difference determines the play time of the broadcast information to be synchronized, and plays described to be synchronized broadcast according to the play time Put information.The program is by separately transmitting video data and broadcast information to be synchronized, and according to the video frame in video data Time difference between timestamp and the timestamp of broadcast information to be synchronized determines the play time of broadcast information to be synchronized, further according to Play time plays broadcast information to be synchronized, improves the broadcasting synchronism of video Yu broadcast information to be synchronized.

For better implementation above method, the present invention also provides another synchronizing information playback methods, with the second letter Breath simultaneously playing device is integrated in for an entity device realization.

The present embodiment will be described from the angle of the second synchronizing information playing device, and with reference to Fig. 2, which is played The detailed process of method can be such that

201, video data is obtained, the video data includes multiple video frames.

202, it when needing to send the video data, retransmits after adding timestamp for the video frame to first service Device.

Specifically, can be the video frame in video data according to the frame per second of video when receiving video transmission instruction Corresponding timestamp is added, for example, adding a timestamp every 2 frames.Then by the video data encoding after addition timestamp Plug-flow is to first server.Wherein, timestamp can be added according to current time.

203, the broadcast information to be synchronized for needing to play with the video data synchronization is obtained.

204, it when needing to send the broadcast information to be synchronized, is added after timestamp again for the broadcast information to be synchronized It is sent to second server.
