Detailed ways

In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

It should be noted that the terms "first" and "second" in the specification and claims of the present disclosure and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein can be practiced in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

In related technologies, the server sends barrage in a full-time manner. In response to the client requesting bullet chatting, according to the current sorting result of the bullet chatting, the first N bullet chatting pieces are delivered, and after the client displays the Nth bullet chatting pieces, the client requests the next batch of bullet chatting. For example, the user watches a 5-minute video from the beginning, and at this time, the first N bullet chats are delivered according to the ranking results of the bullet chats. After analysis, it is found that: after the client has displayed the first N barrages, and the playback progress corresponding to the N barrage is 5 minutes, at this time, the client requests the barrage again from the server, but the client is about to complete the video Play, then, if there are bullet chats posted by other users within the first 5 minutes, the client cannot display these bullet chats, that is, users of this client cannot view bullet chats posted by other users within the previous 5 minutes . Furthermore, because the bullet chatting is delivered in a full-time manner, the N bullet chatting delivered each time may include some bullet chatting with very late playback progress. In the case that the user interrupts the playback for some reason during the playback , some barrages delivered to the client memory are not played, causing unnecessary performance overhead on the client side. For example, if a video is played for 10 minutes, there is no barrage in the first 5 minutes, and there are 200 barrages in the next 5 minutes. Assume that the number of barrages per request is limited to 200. When the playback starts, the client requests Barrage, the client receives 200 barrage. When the video is played to the 3rd minute, the user interrupts the playback. At this time, only some of the 200 barrages are played, and the rest of the barrages are not played, but are sent to the client’s memory through the network, thus wasting resources such as the memory of the client and the network bandwidth of the server.

Based on this, the bullet chatting delivery method provided in the present disclosure can be applied to the application environment shown in FIG. 1 . Wherein, the client 110 interacts with the server 120 through the network. The server 120 may be an electronic device with strong data storage and computing capabilities. For example, the server 120 may be implemented by an independent server or a server cluster composed of multiple servers. Clients 110 may be, but are not limited to, various personal computers, laptops, smart phones, tablets, and portable wearable devices. Wherein, the client 110 installs and runs an application with a video playing function, such as at least one of a browser, a social application, a live broadcast application, a shopping application or a payment application. The video file is provided with a video identification, and the video file has a playing time, such as 1 minute, 3 minutes, or 5 minutes or even longer. The playback duration of the video file is divided into durations to obtain several query time segments. Each query time period includes the start time of the query time and the end point of the query time. The end point of the query time is equal to the sum of the start point of the query time and the preset query duration threshold. For example, if a 2-minute video file is divided, the query duration threshold can be 30 seconds, and the obtained time period can include: 0 to 30 seconds, 31 seconds to 60 seconds, 61 seconds to 90 seconds , 91 seconds to 120 seconds. It should be noted that the preset query duration threshold may be a query duration limited according to the actual situation, for example, between 30 seconds and 60 seconds, and may be 30 seconds, 45 seconds, or 60 seconds. A bullet chatting database is deployed on the server 120, and the bullet chatting database includes video identifiers, query time periods, and corresponding relations of bullet chatting.

In response to the client 110 playing the video file, a first delivery request of the barrage is sent to the server 120. The first delivery request carries the video identifier of the video file being played by the client and the query time period to which the current playback progress belongs. The server 120 receives the first delivery request, and the server 120 searches the bullet chat database according to the video ID and the query time period, obtains the bullet chat set corresponding to the video ID and the query time period, and obtains the bullet chat from the bullet chat collection Target barrage, the target barrage is several barrages that need to be returned to the client. The server 120 returns the target barrage to the client 110, and the client 110 plays the target barrage.

Fig. 2 is a flow chart of a bullet chatting method according to an exemplary embodiment. As shown in Fig. 2, the bullet chatting method is used in the server 120 in Fig. 1 and includes the following steps: S210, receiving the client The first delivery request sent by the terminal; S220, according to the video ID and the query time period, search in the bullet chat database to obtain the bullet chat set corresponding to the video ID and the query time period; S230, obtain the target from the bullet chat collection Barrage, and return the target barrage to the client.

In step S210, a first sending request sent by the client is received.

Wherein, the first sending request carries the video identifier of the video file being played by the client and the query time period to which the current playback progress belongs, and the query time period is obtained by dividing the playing duration of the video file. The video file can have barrage, and the barrage can be distributed at any playback progress of the video file. The current playback progress of the video file played by the client can be understood as a playback time point, which belongs to one of several query time periods of the video file. For example, if a 1-minute video file is divided, the query duration threshold can be 20 seconds, and several query time periods can be obtained, including: 0 to 20 seconds, 21 seconds to 40 seconds, 41 seconds to 40 seconds 60 seconds. When the video file is played to 45 seconds, the current playback progress is 45 seconds, and the current playback progress belongs to the query time period of 41 seconds to 60 seconds. In some embodiments, the client plays a video file. In the case that the video file has a bullet chat, the client sends the first delivery request of the bullet chat to the server. screen, the first sending request not only needs to carry the video ID of the video file being played, but also needs to carry the query time period to which the current playback progress belongs.

In step S220, according to the video identifier and the query time period, a search is performed in the bullet chat database to obtain a bullet chat set corresponding to the video identifier and the query time period.

Among them, the bullet chat database can be deployed on the server, and the table structure of the bullet chat database can include video identification, bullet chat location, bullet chat identification, bullet chat content, etc. The bullet chatting position can be understood as the position of the bullet chatting in the video playback progress, that is, the bullet chatting posted by the user when the video is played to the video playback progress. The bullet chatting database stores the content of the bullet chatting posted by the user and the corresponding The playback progress of the video (that is, the barrage position). The content of the barrage can be understood as the text, pictures, emojis and other information corresponding to the barrage, such as "Does Tyson and Douglas have a second fight?" and other text content. In some embodiments, the server searches the bullet chat database according to the video identifier and the query time period, and determines the bullet chat set within the query time period in the bullet chat corresponding to the video identifier. For example, if the current playback progress belongs to the query time period of 41 seconds to 60 seconds, the searched barrage set can be the barrage set within the query time period of 41 seconds to 60 seconds, which can be understood as any user watching the video A collection of bullet chats published when the video content is 41 seconds to 60 seconds long.

In step S230, the target bullet chat is obtained from the bullet chat collection, and the target bullet chat is returned to the client.

Among them, the target barrage is several barrages that need to be returned to the client, and the client is used to play the target barrage. In some embodiments, the bullet chatting set corresponding to the query time period to which the current playback progress belongs has been found from the bullet chatting database. Part of the bullet chat or all the bullet chats can be obtained from the bullet chat collection as the target bullet chat, and the target bullet chat is sent to the client, and the client plays the target bullet chat. The current user watching the video on the client can see the query time period target barrage. Exemplarily, for example, the duration of each query period is agreed to be 30 seconds. When the video is played to the 15th second, a barrage of 0 to 30 seconds is received from the server. At this time, other users watch the video In the case of the video content after 30 seconds, and publish the barrage at the playback progress, wait until the current user watches the playback progress after 30 seconds (for example, 45 seconds, which belongs to the query time period of 31 seconds to 60 seconds) , the server sends the barrage posted by other users in the query time period to which the playback progress belongs in real time.

The above-mentioned bullet chatting delivery method is obtained by receiving the first delivery request carrying a video identifier and a query time period, and the query time period is obtained based on dividing the playing duration of the video file; and according to the video identifier and the query time period in the bullet chat database Search to obtain the corresponding barrage set; thus obtain the target barrage from the barrage set, and return the target barrage to the client, which not only reduces the number of barrages sent each time, but also reduces the impact of the barrage to be played on the client It also reduces the occupation of server-side network bandwidth and improves the real-time performance of barrage playback.

In some embodiments, as shown in Figure 3, obtaining the target bullet chat from the bullet chat collection and returning the target bullet chat to the client can be achieved through the following steps: S310, the number of bullet chat in the bullet chat collection is greater than In the case of the preset barrage return upper limit, obtain target barrages whose number is equal to the barrage return upper limit from the barrage collection, and assign the page turning field as the first result value; S320, combine the target barrage and the first result value The resulting value is returned to the client.

In step S310, when the number of bullet chats in the bullet chat collection is greater than the preset bullet chat return upper limit, obtain the target bullet chat with a quantity equal to the bullet chat return upper limit from the bullet chat collection, and assign a value to the page turning field is the first result value.

Among them, the upper limit of bullet chatting return can be the maximum number of bullet chatting sent by the server to the client each time, and the upper limit of bullet chatting return can be set in combination with the performance parameters of the client and the performance parameters of the server. In the case that the upper limit of bullet chatting is 200, the server can send up to 200 bullet chatting to the client each time. In some embodiments, the bullet chatting set corresponding to the query time period to which the current playing progress belongs is searched from the bullet chatting database. Compare the set barrage return upper limit. The number of bullet chatter in the bullet chat collection can be greater than the preset bullet chat return limit, the bullet chat number in the bullet chat collection can be equal to the preset bullet chat return upper limit, and the bullet chat number in the bullet chat collection can be less than the preset bullet chat screen returns to the upper limit.

If the number of bullet chats in the bullet chatting collection is greater than the upper limit of bullet chatting returns, it means that the bullet chatting in the bullet chatting collection cannot be sent to the client all at once, so the page turning field needs to be set. The page turning field is used to indicate whether there are remaining bullet chatting in the bullet chatting set besides the target bullet chatting returned to the client (these remaining bullet chatting are regarded as bullet chatting to be delivered). The page turning field can be understood as a field provided by the server to the client interface and returned. Assign values to the page turning field according to the comparison result between the number of bullet chatter in the bullet chat collection and the preset bullet chat return upper limit. In the case that the number of bullet chatting in the bullet chat collection is greater than the upper limit of the bullet chatting returned, the page turning field is assigned the first result value. The first result value is used to represent that in the bullet chatting set, there are bullet chatting to be delivered besides the target bullet chatting returned to the client.

In order to reduce the memory usage of the client, the number of bullet chats sent by the server to the client is limited. Therefore, the target bullet chat can be obtained from the bullet chat collection corresponding to the query time period to which the current playback progress belongs according to the order of the bullet chat IDs. The number of target barrage is equal to the upper limit of barrage return.

In step S320, the target barrage and the first result value are returned to the client.

Wherein, the first result value is also used to instruct the client to send the second sending request. In some embodiments, the server searches the bullet chatting database to obtain the bullet chatting collection, and obtains the target bullet chatting from the bullet chatting collection. When the number of bullet chatting in the bullet chatting collection is greater than the upper limit of bullet chatting, the server assigns the page turning field to the first result value. The server returns the target bullet chatting and the first result value to the client, and the client receives and plays the target bullet chatting. When the target bullet chatting is finished playing, the first result value tells the client to remove the returned bullet chat from the bullet chatting collection. In addition to the target barrage to the client, there are still barrages to be delivered, so the client can send a second delivery request to the server to pull the barrage to be delivered.

In some embodiments, by setting the page turning field and assigning a value to the page turning field according to the comparison result of the number of bullet chatting in the bullet chatting collection and the preset bullet chatting return upper limit, it is ensured that the client can pull to the server again Barrage, to realize page-by-page playback of barrage, play barrage as much as possible, and strengthen interaction with users. And by setting the upper limit of barrage return, reduce the impact on client performance.

In some embodiments, each bullet chat in the bullet chat to be delivered has an identification. As shown in Figure 4, in response to the video playback progress when the target bullet chatting is finished playing still belongs to the query time period, the bullet chat delivery method also includes: S410, receiving the second delivery request; S420, still according to the video identification and the query time period Search in the barrage database to obtain the barrage set; S430, filter from the barrage set according to the first result value to obtain the barrage to be sent; S440, sequentially select the barrage from the barrage to be issued according to the identification of each barrage Obtain a new target barrage, and return the new target barrage to the client.

In step S410, a second delivery request is received.

In step S420, the bullet chatting database is still searched according to the video ID and the query time period to obtain the bullet chatting set.

Wherein, the second sending request carries a query time period, a video identifier and a first result value, and the first result value is used to represent the identifier of the target barrage that has been returned to the client. In some embodiments, when the number of bullet chatting in the bullet chat collection is greater than the upper limit of bullet chatting returns, the page turning field is assigned the first result value. In response to the server returning the target bullet chat and the first result value to the client, the client receives and plays the target bullet chat. When the target bullet chat is finished playing, the client can send the second bullet chat to the server because the first result value informs the client that there are bullet chats to be sent in addition to the target bullet chat returned to the client in the bullet chat collection. Sending the request, the server receives the second sending request. The second sending request carries the first result value, the query time period and the video ID. The server still searches the bullet chat database according to the video ID and query time period, and obtains the bullet chat collection corresponding to the video ID and query time period.

In step S430, screen the bullet chatting set according to the first result value to obtain the bullet chatting to be sent.

Wherein, the remaining bullet chatting refers to other bullet chatting in the bullet chatting collection except the target bullet chatting returned to the client. In some embodiments, the first result value can inform the server which bullet chatting is the target bullet chatting returned to the client. Therefore, according to the first result value, it is screened from the bullet chatting collection, and the target bullet chatting that has been returned to the client is processed. Filter to get the bullet chatting collection recomposed from the remaining bullet chatting.

In step S440, new target bullet chats are sequentially obtained from the bullet chats to be sent according to the identifiers of each bullet chat, and the new target bullet chats are returned to the client.

Among them, the number of bullet chats to be delivered can be greater than or less than the upper limit of bullet chat returns. In some embodiments, the bullet chatting in the bullet chat database can be stored in a preset order (such as the time when the bullet chatting is sent), and similarly, the bullet chatting in the bullet chatting to be sent can be stored in a preset order of. Each barrage in the barrage to be delivered has an identifier, and a new target barrage is obtained from the barrage to be delivered according to the identifier of each barrage. When the number of bullet chats to be sent is greater than the upper limit of bullet chats to be sent, the server obtains a number of bullet chats equal to the upper limit of bullet chats to be sent as the new target bullet chat. When the number of bullet chats to be sent is less than the upper limit of bullet chats returned, the server will use the bullet chats to be sent as the new target bullet chat. The server returns the new target barrage to the client, and the client receives the new target barrage, and further, the client can also play the new target barrage.

In some embodiments, when the number of bullet chatting in the bullet chatting collection is greater than the upper limit of bullet chatting return, in response to the target bullet chatting being returned to the client, it is filtered from the bullet chatting collection according to the first result value to obtain the next Send bullet chatting; obtain new target bullet chatting from the bullet chatting to be sent in turn according to the identification of each bullet chatting, and return the new target bullet chatting to the client. It can be seen that in some embodiments, the searched barrage collection is sent to the client in multiple pages, and on the premise of reducing the performance overhead of the client, it is also ensured that the client can play more barrage, and strengthen the relationship with the user. interactivity between them.

In some embodiments, as shown in Figure 5, obtaining the target bullet chat from the bullet chat collection, and returning the target bullet chat to the client, includes the following steps:

In step S510, when the number of bullet chats in the bullet chat collection is not greater than the preset bullet chat return upper limit, obtain all bullet chat from the bullet chat collection as the target bullet chat, and assign the page turning field to the second result value.

In step S520, the barrage set and the second result value are returned to the client.

Wherein, the second result value is used to inform the client that all bullet chats in the bullet chat collection have been returned to the client. In some embodiments, the server compares the number of bullet chats in the bullet chat collection with the preset bullet chat return upper limit, and if the bullet chat number in the bullet chat collection is not greater than the bullet chat return upper limit, it means that the bullet chat can be returned Each bullet chat in the set is sent to the client, and all bullet chats are obtained from the bullet chat collection as the target bullet chat. Set the value of the page turning field, indicating that there is no other bullet chatting in the bullet chatting collection except the target bullet chatting returned to the client, that is, assign the page turning field to the second result value, so as to inform the client of the bullet chatting through the second result value All bullet chats in the collection have been returned to the client.

In some embodiments, when the number of bullet chatting in the bullet chatting collection is not greater than the bullet chatting return upper limit, the page turning field is assigned the second result value, and the bullet chatting collection and the second result value are returned to the client . Use the second result value to inform the client not to send the second delivery request to the server, so as to avoid the client sending a delivery request to the server when the server has already delivered all bullet chats within the query time period , thereby further reducing the bandwidth resource occupation of the server.

In some embodiments, the second result value is further used to instruct the client not to send the second sending request in response to the video playing progress when the bullet chatting set finishes playing and still belongs to the query time period.

In some embodiments, the server returns the bullet chat collection and the second result value to the client, and the client receives the bullet chat collection and plays the bullet chat collection. In response to the completion of playing the barrage set, it is judged whether the video playback progress of the client belongs to the query time period. Then, when the barrage collection finishes playing, the client no longer sends the second delivery request to the server according to the second result value. Exemplarily, the second result value may be a preset value, such as 0. In response to the client detecting that the value assigned to the page turning field is 0, the client does not send a second delivery request to the server when the barrage set is played.

In some embodiments, in response to the video playback progress when the barrage collection completes playing still belongs to the query time period, the second result value indicates that the client does not send the second delivery request, which not only reduces the bandwidth resource occupation of the server, but also And further reduce the performance overhead of the client to ensure the smooth operation of the client.

In some embodiments, the bullet chat delivery method further includes: in response to the video playback progress when the target bullet chat is finished playing no longer belongs to the query time period, receiving a third delivery request sent by the client, the third delivery request carrying a new query time period.

Among them, the client receives the target bullet chat and plays it. When the target bullet chat is finished playing, it judges whether the video playback progress when the target bullet chat is finished playing belongs to the query time period used in the previous query. It does not belong to the query time period used in the last query, indicating that the video playback progress belongs to the new query time period, and the client can pull the barrage corresponding to the new query time period from the server. In some embodiments, in response to the video playback progress when the target barrage finishes playing no longer belongs to the query time period, the client sends a third sending request to the server, and the server receives the third sending request, and the third The sending request carries the new query time period and video identifier to which the video playback progress belongs. The server can search the bullet chat database according to the new query time period and video ID to obtain a new bullet chat collection. The bullet chatting position of the new bullet chat collection is within the new query time period. The target bullet chat in the new query time period can be obtained from the new bullet chat collection, and the client receives and plays the target bullet chat in the new query time period.

In some embodiments, in response to the video playback progress when the target barrage finishes playing no longer belongs to the query time period, the third delivery request sent by the client is received to ensure that when the user watches the subsequent playback progress, real-time Pull the barrage posted by other users to improve the fit between the barrage playback status and video playback progress and the real-time performance of the barrage.

In some embodiments, in response to the video playback progress when the target bullet chatting is finished playing no longer belongs to the query time period, if there are still unplayed bullet chatters in the bullet chatting set corresponding to the query time period, the unplayed bullet chatting will not be issued. The barrage is sent to the client, so that it can ensure that the barrage played corresponds to the progress of the video playback.

In some embodiments, the query time period includes the start time of the query time and the end time of the query time, and the end time of the query time is equal to the sum of the start time of the query time and a preset query duration threshold.

Wherein, the video file has a playback duration, and the playback duration of the video file is divided to obtain several query time periods, and the query time period corresponds to the playback progress of the video file. As mentioned above, the query duration threshold can be set according to the actual situation. In some embodiments, the query time period includes the start time of the query time and the end point of the query time, and the start point of the query time (positionFromInclude) may correspond to the playback progress at the first time point in the video file as the starting point of the query time period. The end point of the query time (positionToInclude) may correspond to the playback progress at the second time point in the video file. As the end point of the query time period, the first time point is earlier than the second time point. The end point of the query time is equal to the sum of the start point of the query time and the preset query duration threshold.

In some embodiments, several query time periods are obtained by dividing the playback duration of the video file, and the end point of the query time is equal to the sum of the start point of the query time and the preset query duration threshold, and the query time period and video playback progress are established. The corresponding relationship, to achieve accurate control of the bullet chatting from the server, and to ensure the real-time performance of the bullet chatting. Furthermore, compared with the full-time method in the related art, the number of bullet chatting in the query time period is small, which can reduce the memory occupation of the client terminal by bullet chatting.

Fig. 7 is a flow chart of a bullet chatting receiving method according to an exemplary embodiment. As shown in Fig. 7, the bullet chatting receiving method is used in the client 110 in Fig. 1 and includes the following steps:

In step S710, a first delivery request is sent to the server.

In step S720, the target barrage returned by the server is received.

Among them, the first sending request carries the video ID of the video file being played by the client and the query time period to which the current playback progress belongs. The query time period is obtained by dividing the playing time of the video file. A number of bullet chats obtained from the bullet chat collection. The bullet chat collection is a collection of bullet chats corresponding to the video ID and the query time period obtained by searching the bullet chat database on the server side according to the video ID and the query time period. The barrage database includes the corresponding relationship between video identification, query time period and barrage.

In some embodiments, the client plays a video file, and if the video file has a bullet chat, the client sends a first delivery request of the bullet chat to the server. The server searches the bullet chat database according to the video identifier and the query time period, and determines the bullet chat set within the query time period in the bullet chat corresponding to the video identifier. In order to ensure the real-time display of bullet chats (that is, to see the bullet chats posted by other users in real time), the server obtains part or all of the bullet chats from the bullet chat collection as the target bullet chat. The server returns the query result to the client, and the client receives the query result, which includes the target barrage in the query time period. Furthermore, the client can play the target barrage, and the current user watching the video on the client side can see the target barrage in the query time period in real time.

In the method for receiving a barrage above, the client can play the target barrage by sending the first delivery request to the server and receiving the target barrage returned by the server. It can not only reduce the memory usage of the bullet chat to be played on the client side, but also save the bandwidth resources occupied by the server when sending the bullet chat, and improve the real-time performance of the bullet chat.

In some embodiments, receiving the target barrage returned by the server includes: receiving the target barrage and the first result value returned by the server.

Among them, when the number of bullet chats in the bullet chat collection is greater than the preset bullet chat return upper limit, the target bullet chat is a number of bullet chats that the server obtains from the bullet chat collection equal to the bullet chat return upper limit, and the first result is The value is the assignment of the page turning field by the server, and the first result value is used to indicate that the bullet chatting set still contains bullet chatting to be delivered, and the first result value is also used to instruct the client to send the second delivery request.

In some embodiments, the bullet chatting set has a certain number, and the number of bullet chatting in the bullet chatting set is compared with the preset bullet chatting return upper limit. The number of bullet chatter in the bullet chat collection can be greater than the preset bullet chat return limit, the bullet chat number in the bullet chat collection can be equal to the preset bullet chat return upper limit, and the bullet chat number in the bullet chat collection can be less than the preset bullet chat screen returns to the upper limit. If the number of bullet chats in the bullet chatting collection is greater than the upper limit of the bullet chatting return, it means that the bullet chatting in the bullet chatting collection cannot be sent to the client all at once, and the bullet chatting in the bullet chatting collection needs to be sent multiple times , so a page-turning field needs to be set. Use the page turning field to indicate whether there are other bullet chats in the bullet chat collection besides the target bullet chat returned to the client. It should be noted that the page turning field can be understood as a field provided by the server and returned by the client interface. If the number of bullet chatting in the bullet chatting collection is greater than the upper limit of bullet chatting returned, the server assigns the page turning field as the first result value.

The server returns the target bullet chat and the first result value to the client, and the client can receive and play the target bullet chat, because the first result value informs the client that in the bullet chat collection, there are also There are other bullet chats to be delivered, so the client can send a second delivery request to the server according to the first result value to pull the bullet chats to be delivered.

In some embodiments, by setting the page turning field and assigning a value to the page turning field according to the comparison result of the number of bullet chatting in the bullet chatting collection and the preset bullet chatting return upper limit, the value of the page turning field indicates whether the client Send the request to the server again to pull the barrage, realize the page-turning playback of the barrage in the barrage collection, play as many barrages as possible, and strengthen the interaction with users. And by setting the upper limit of barrage return, reduce the impact of barrage on client performance.

In some embodiments, each bullet chat in the bullet chat to be sent has an identifier, and the first result value is also used to represent the identifier of the target bullet chat that has been returned to the client. The bullet chat delivery method further includes: in response to the video playback progress when the target bullet chat is finished playing still belongs to the query time period, sending a second delivery request to the server, and receiving a new target bullet chat returned by the server.

Among them, the second delivery request carries the query time period, video ID and the first result value. The new target bullet chat is that the server still searches the bullet chat database according to the video ID and query time period to obtain the bullet chat collection. According to the first result value, the bullet chatting set is screened to obtain the bullet chatting to be delivered, and a preset number of bullet chatting is obtained from the bullet chatting to be delivered sequentially according to the identification of each bullet chatting.

In some embodiments, when the number of bullet chatting in the bullet chat collection is greater than the upper limit of bullet chatting returns, the page turning field is assigned the first result value. The server returns the target barrage and the first result value to the client, and the client receives and plays the target barrage. The client can judge whether the video playback progress when the target bullet chat is finished playing belongs to the query time period when the target bullet chat is finished playing, and respond to the video playback progress when the client finishes playing the target bullet chat still belongs to the query time period , the client sends a second delivery request to the server. The second sending request carries the first result value, the query time period and the video identifier. Therefore, the server still searches the bullet chat database according to the video identifier and the query time period, and determines the bullet chat set within the query time period in the bullet chat corresponding to the video identifier. In addition, the first result value is used to represent the identity of the target bullet chat that has been returned to the client, that is, the first result value can tell the server which bullet chat is the target bullet chat returned to the client. Therefore, the server uses the first result value to Filter from the bullet chatting collection, filter the target bullet chatting that has been returned to the client, and get the bullet chatting to be sent recomposed from other bullet chatting. Bullet chats to be delivered can be understood as other bullet chats in the bullet chat collection except the target bullet chat returned to the client.

It should be noted that when the number of bullet chats to be sent is greater than the upper limit of bullet chats returned, the server obtains target bullet chats whose number is equal to the upper limit of bullet chats to be sent. When the number of bullet chats to be sent is less than the upper limit of bullet chats returned, the server will use the bullet chats to be sent as the new target bullet chat. Then, the server returns the new target barrage to the client, and the client receives and plays the new target barrage.

In some embodiments, receiving the target barrage returned by the server includes: receiving the target barrage and the second result value returned by the server.

Among them, when the number of bullet chats in the bullet chat collection is not greater than the preset bullet chat return upper limit, the target bullet chat is all the bullet chats obtained by the server from the bullet chat collection, and the second result value is the server-side flip The assignment of the page field, and the second result value is used to indicate that all the bullet chatting in the bullet chatting collection have been returned to the client.

In some embodiments, the server compares the number of bullet chats in the bullet chat collection with the preset bullet chat return upper limit, and if the bullet chat number in the bullet chat collection is not greater than the bullet chat return upper limit, it means that the bullet chat can be returned Each bullet chat in the set is sent to the client, and all bullet chats are obtained from the bullet chat collection as the target bullet chat. Set the value of the page turning field, indicating that there is no other bullet chatting in the bullet chatting collection except the target bullet chatting returned to the client, that is, assign the page turning field to the second result value, so as to inform the client of the bullet chatting through the second result value All bullet chats in the collection have been returned to the client. Therefore, the server returns the target barrage and the second result value to the client, and the client receives the target barrage and the second result value.

In some embodiments, when the number of bullet chatting in the bullet chatting collection is not greater than the bullet chatting return upper limit, the server assigns the page turning field to the second result value, and returns the second result value to the client. Use the second result value to inform the client not to send the second delivery request to the server, so as to avoid the client sending a delivery request to the server when the server has already delivered all bullet chats within the query time period , thereby further reducing the bandwidth resource occupation of the server.

In some embodiments, in response to the fact that the video playback progress when the bullet chatting collection finishes playing still belongs to the query time period, no second delivery request is sent to the server according to the second result value.

Wherein, the second result value is used to indicate that there is no bullet chatting to be delivered in the bullet chatting set except the target bullet chatting returned to the client, and the bullet chatting set is the target bullet chatting. In some embodiments, in the case that the number of bullet chats in the bullet chat collection is not greater than the upper limit of bullet chat return, it means that each bullet chat in the bullet chat collection can be sent to the client. Also, set the page turning field as the second result value. The server uses the bullet chat collection as the target bullet chat, the server returns the bullet chat collection and the second result value to the client, and the client receives the bullet chat collection and the second result value. The client judges whether the video playback progress when the bullet chat collection finishes playing belongs to the query time period. If the video playback progress belongs to the query time period, since the second result value indicates that there is no bullet chat to be sent within the query time, then After finishing playing the barrage set, the client no longer sends the second sending request to the server according to the second result value.

In some embodiments, when the number of bullet chatting in the bullet chat collection is not greater than the bullet chat return upper limit, the client receives the bullet chat collection returned by the server, and responds that the video playback progress remains the same when the bullet chat collection completes playing. In the query period, the client will no longer send a second delivery request to the server, further reducing the bandwidth resource occupation of the server, reducing the performance overhead of the client, and ensuring the smooth operation of the client.

In some embodiments, the bullet chat delivery method further includes: in response to the video playback progress when the target bullet chat is finished playing no longer belongs to the query time period, sending a third delivery request to the server, the third delivery request carrying a new Query time period.

In some embodiments, the client receives and plays the target bullet chat, and when the target bullet chat is finished playing, it is judged whether the video playback progress when the target bullet chat is finished playing belongs to the query time period used in the last query, If the video playback progress does not belong to the query time period used in the previous query, it indicates that the video playback progress belongs to the new query time period, and the client can pull the barrage corresponding to the new query time period from the server. The client sends a third delivery request to the server, and the server receives the third delivery request, where the third delivery request carries a new query time period and a video identifier to which the video playback progress belongs. The server can search the bullet chat database according to the new query time period and video ID to obtain a new bullet chat collection. The bullet chatting position of the new bullet chat collection is within the new query time period.

In some embodiments, in response to the video playback progress when the target barrage finishes playing no longer belongs to the query time period, the third delivery request is sent to the server to ensure that when the user watches the subsequent playback progress, Real-time pull to the barrage posted by other users.
