In this embodiment, a method for delivering multimedia content is provided, as shown in fig. 1b, the specific flow of the method for delivering multimedia content may be as follows:

110. multimedia content, a delivery policy for the multimedia content, and at least one task object are obtained.

The delivery strategy comprises delivery time and terminal information of at least one terminal to be delivered, and the number of task objects is not more than the number of the terminals to be delivered.

Wherein, the multimedia content can refer to man-machine interaction information communication and propagation media, and can comprise video, audio, pictures, characters and the like. For example, each multimedia content may include any one of video, audio, picture, or text, and may also include at least two of video, audio, picture, or text, and so on.

The delivering policy may refer to a policy of delivering the multimedia content to a terminal, and the terminal receiving the delivered multimedia content may be a terminal to be delivered. The delivery policy may include information related to content delivery, such as push time, delivery duration, display mode, display trigger conditions, terminal information, and the like. Wherein, the push time may refer to a time of transmitting the multimedia content from the server to the terminal; the delivery time may refer to a time when the multimedia content is delivered on an application program of the terminal, and the delivery time may be one or more time periods; the display mode can refer to a display mode when the multimedia content is put on the terminal, for example, the display mode can comprise UI arrangement, a switching mode and the like, and the switching mode can comprise modes such as carousel, single diagram, popup, announcement, list, screen flashing, screen cutting and the like; the display triggering condition may refer to a condition that the display is triggered on the application program of the terminal, for example, the multimedia content may be automatically displayed in a time period of the release time, or may be displayed each time the application program is started; the terminal information may refer to information of the terminal to be delivered, and may include, for example, a terminal identification of the terminal to be delivered, such as a device code, an address of the terminal to be delivered, such as an IP address, and the like.

Where an object may refer to a basic unit of a computer program, for example, in object-oriented programming ((Object Oriented Programming)), the computer program may be considered a collection of objects, which may contain functions of data and operational data, each of which may receive messages from other objects and process those messages, and execution of the computer program is a series of messages passing between the various objects. A task object may refer to an object for handling a launch task.

For example, the multimedia content may be uploaded to a configuration platform carried by a server, and a delivery policy may be set, where the delivery policy may include a delivery time t and terminal information of m terminals to be delivered. Thus, the server can construct n task objects through the construction function, wherein n is not greater than m. Each task object can correspond to one terminal to be launched, and multimedia content, launching time, terminal information of the terminal to be launched corresponding to the task object and the like can be processed by calling a function in the task object to obtain a file to be launched, so that the file to be launched is issued to the terminal to be launched corresponding to the task object.

In some embodiments, the delivery policy may be determined by setting delivery parameters such as attribute information of a crowd, so that different delivery policies may be set according to different crowd attributes to provide diversified and directional content delivery. In particular, the obtaining the multimedia content, the delivery policy of the multimedia content, and the at least one task object may include:

Acquiring multimedia content and delivery parameters, wherein the delivery parameters comprise delivery time and attribute information of people to be delivered;

acquiring terminal information of at least one terminal to be put according to attribute information of the crowd to be put, wherein the terminal to be put is a terminal corresponding to the attribute information;

and constructing at least one task object according to the number of the terminals to be launched.

The delivery parameters may refer to parameters for determining a delivery policy, and may be preset parameters or parameters set by a user. For example, the delivery parameters may include parameters of information related to content delivery, such as push time, delivery duration, display mode, display trigger condition, attribute information of the crowd to be delivered, and the like.

The crowd to be put can refer to the crowd to be put with the multimedia content, and the crowd to be put can be selected according to actual needs.

Wherein, the attribute information may refer to information capable of being used for characterizing the characteristics of the crowd, and the attribute may include natural attributes or social attributes of the crowd, and the like. For example, the crowd can be classified into different types according to the characteristics of the crowd, and the types are the attribute information of the crowd. For example, the internet information of the user can be obtained under the condition of obtaining the consent of the user, and the user is classified into a follow-up group or a buying group, and the attribute information of the crowd formed by the users belonging to the follow-up group is the follow-up group.

For example, in the case where user consent is obtained, terminal information of a terminal associated with the server and attribute information of a user who uses the associated terminal may be stored in advance in the server. Therefore, the delivery parameters such as the push time, the delivery duration, the display mode, the display trigger condition, the attribute information of the crowd to be delivered and the like can be set through the configuration platform carried on the server, wherein the attribute information of the crowd to be delivered can be a follow-up group, so that the terminals corresponding to all users with the attribute of the follow-up group can be determined as the terminals to be delivered, the terminal information of the terminals to be delivered can be obtained, and the delivery strategy is generated by combining other information in the delivery parameters such as the push time, the delivery duration, the display mode, the display trigger condition and the like. After the launch strategy is generated, task objects with the number not greater than the number of the terminals to be launched can be constructed through a construction function according to the number of the terminals to be launched.

120. And updating the information carried by the task object according to the multimedia content and the delivery strategy to obtain updated information.

The information carried by the task object may refer to data in the object, for example, may refer to an identifier that is transmitted in a parameter form through a constructor when the task object is constructed. The information carried by the task object may include, but is not limited to, key information extracted from the multimedia content and the delivery policy, for example, may include an address of the multimedia content, a delivery time, an address of a terminal to be delivered, and the like, and may also include information such as a display mode, a display trigger condition, and the like.

In some embodiments, when constructing the task object, the identifier which is transmitted in the form of parameters by the construction function can be used for storing the multimedia content information and the terminal information of the terminal to be launched in the task object in the form of the identifier, so that the corresponding identifier information can be read by calling the function in the task object. Specifically, the information that the task object may carry may include identification information, and the identification information may include multimedia content information and terminal information of the terminal to be put in.

For example, the multimedia content information may be a tag task, and the terminal information of the terminal to be delivered may be a target communication address. The tag task may include a multimedia content address, such as a multimedia content address of a material, a picture, an audio/video file, etc., and the target communication address may include an address of a terminal to be released, such as a terminal IP after DNS resolution. the tag task may also include an address of information such as push time, display mode, display trigger condition, and the like.

Optionally, when constructing the task object, the obtained identifier of the task object is an initial value, key information can be extracted from the multimedia content and the delivery strategy, and the key information is transmitted into the identifier of the task object to update the identifier information carried by the task object.

130. And processing the updated information carried by the task object to obtain a file to be released corresponding to the terminal information.

The file to be released may refer to a file to be released obtained after the task object processes the updated information. The to-be-released file corresponding to the terminal information may refer to a to-be-released file corresponding to the to-be-released terminal of the terminal information, that is, the to-be-released file is used for being issued to the to-be-released terminal of the terminal information.

For example, a function of operation data in a task object can be called by a creation thread to process updated information in the task object to obtain a file to be released, wherein the file to be released can include information related to content release, such as multimedia content, push time, release duration, display mode, display trigger condition, terminal information of a terminal to be released and the like. And when the file to be released is obtained, the file to be released can be released to the terminal corresponding to the terminal information according to the terminal information recorded in the file to be released.

140. And updating the updated information carried by the task object into an initial value so as to use the task object to obtain a file to be released corresponding to the information of the next terminal.

The to-be-released file corresponding to the next terminal information may refer to a to-be-released file obtained by performing steps 120 to 130 again after the task object is processed to obtain the to-be-released file. And the file to be released corresponding to the next terminal information is used for being issued to the terminal to be released corresponding to the next terminal information.

For example, if there are terminal information of m to-be-launched terminals, the server constructs n task objects through a constructor, n is smaller than m, in the process of step 120-130, the n task objects may generate n to-be-launched files corresponding to the n to-be-launched terminals, and m-n to-be-launched files corresponding to the n to-be-launched terminals, at this time, the updated information carried by the task objects may be updated to an initial value, if m-n is less than or equal to n, the updated m-n task objects are used to generate m-n to-be-launched files corresponding to the m-n to-be-launched terminals, if m-n is greater than n, the updated n task objects are used to generate n to-be-launched files corresponding to the n to-be-launched terminals in the m-n to-be-launched terminals, and so on until all to-be-launched terminals have the corresponding to-be-launched files.

It should be noted that, if the number of task objects is the same as the number of terminals to be released, for example, 1, the task objects may generate files to be released corresponding to all the terminals to be released at one time, and at this time, after updating the updated information carried by the task objects to an initial value, a process of using the task objects to obtain the files to be released corresponding to the information of the next terminal may not be executed.

It should be noted that, step 140 may be before step 150 or after step 150. The updated information carried by the task object is updated to an initial value after the file to be released is processed by the task object and before the file to be released is sent; after the sending operation of the file to be released is executed, the updated information carried by the task object is updated to an initial value.

In some embodiments, when the information that the task object may carry includes identification information, the identification information may be set to an initial value. For example, the values in the tag task and the target communication address may be updated to initial values.

In some implementations, different states may be set for task objects to implement multiplexing task objects. Specifically, the identification information carried by the task object may further include status information of the task object.

For example, the identification information of the task object may further include status information of the task object acquired when the task is processed by communication.

Alternatively, the state information may include a new state, a task state, a multiplexing state, and the like. When constructing a task object, the obtained state information of the task object is in a new state, the state information of the task object is in a task state when the task object processes and generates a file to be released and issues the file, and the state information of the task object after the completion of issuing is in a multiplexing state. Therefore, the initial value of the state information can be in a multiplexing state, when the information carried by the task object is updated, the state information of the task object can be updated from a new state or multiplexing state to a task state, and when the file to be released is obtained and the file to be released is issued, the task state can be updated to the multiplexing state.

Optionally, when the task object is used for obtaining the file to be released corresponding to the next terminal information, the task object in the multiplexing state is preferentially searched for obtaining the file to be released corresponding to the next terminal information, so that the utilization rate of the task object is improved.

In some embodiments, each task object may be processed in parallel by a plurality of parallel threads, so as to improve efficiency of generating the file to be released. Specifically, processing updated information carried by the task object to obtain a file to be released may include:

and when a plurality of task objects exist, the updated information carried by the task objects is processed in parallel through a plurality of threads.

For example, after constructing n task objects, n threads may be established to execute the workflows of the n task objects, respectively, so as to implement parallel processing of the n task objects.

150. And sending the file to be released to the terminal to be released so that the application program running on the terminal to be released displays the multimedia content in the releasing time.

The application may be an application running a content platform. The content platform may be a service type platform providing various kinds of content, through which a user can acquire content and use a service of the content. The type of the content is not limited in the present application, and may be various types of content such as video, audio, game, live broadcast, online shopping, application download, and the like. That is, the solution provided by the embodiments of the present application may be applicable to a content platform that provides different types of content, and may also be applicable to a comprehensive content platform that provides multiple types of content. The content platform can be operated in the form of App, H5, applet, etc. in the terminal to be launched.

For example, after receiving the file to be released, the terminal to be released can read the file to be released, and display the multimedia content in the application program of the terminal according to the released time read.

Optionally, when the file to be released is generated, information such as releasing time can be stored in a preset field of the head of the file to be released, and information such as a multimedia content field is stored after the preset field, so that the terminal to be released can know the releasing time only by analyzing the characters of the preset field of the head when receiving the file to be released, and the reading efficiency is improved.

In the prior art, an application program of a terminal generally acquires multimedia content from a server of a delivery platform after starting, displays the multimedia content acquired in the last starting time when starting next time, and requires the terminal to initiate a request to the server to acquire the multimedia content, so that the delivery process is complex. However, in the method provided by the application, after the file to be released is generated, the file to be released can be actively sent to the terminal, so that the releasing flow is simplified, the computing resources are saved, the file to be released is generated through the multimedia content, the releasing strategy and the task object, and the terminal can timely release the multimedia content according to the releasing time in the releasing strategy after receiving the file to be released, so that the timeliness of releasing the multimedia content is improved.

In the prior art, when multimedia content is put in, a terminal and a server are generally connected in a short connection mode, and the content can be put in only by a plurality of interaction processes, so that the putting process is complex and the timeliness is poor.

In some embodiments, before the terminal to be released is started for the first time, a long connection channel between the server and the terminal to be released is established, so that the server and the terminal to be released are connected in a long connection mode, after the server generates the file to be released, the file to be released can be actively sent to the terminal through the long connection channel, the releasing process is simplified, and the computing resources are saved. Specifically, before sending the file to be released to the terminal to be released, the method may further include:

when the terminal to be released starts an application program for the first time, a long connection channel is established, and the long connection channel is a channel for sending the file to be released to the terminal to be released.

For example, the method of the embodiment of the present application may be executed by a delivery server, where the delivery server may refer to a server for delivering multimedia content to a terminal to be delivered, the delivery server may include a configuration server and a push server, the configuration server is equipped with a configuration platform, a user may upload the multimedia content and set delivery parameters on the configuration platform, the configuration platform may determine a delivery policy and construct a task object according to the delivery parameters, and then generate a file to be delivered by the delivery policy and the task object, and send the file to be delivered to the push server, where the push server may issue the file to be delivered to the corresponding terminal to be delivered.

Optionally, establishing the long connection channel may include:

acquiring a data packet sent by a terminal to be put in, wherein the data packet is a data packet which is generated by the terminal to be put in and is used for creating a long connection channel;

and establishing a long connection channel according to the data packet.

The method for generating the protocol packet may include: determining an address of a terminal to be put in and a port of a put-in server; and setting an interface function between the release server and the terminal to be released according to the memory address and the port, and generating a protocol packet.

For example, as shown in fig. 1c, after an application program is installed on a terminal to be launched, when the application program is launched for the first time, the terminal to be launched may initiate creation of a long connection channel, call an incoming parameter through a socket function to determine a protocol domain and a protocol type, the incoming parameter may be the protocol domain and the protocol type, a value of the protocol domain may be IPV6 or IPV4, a value of the protocol type may be TCP or UDP, a memory is opened locally to store a sockaddr_in structure pointer, the structure pointer may include a port of a push server, an IP address of the push server, and an encryption/decryption algorithm, set up and receive a corresponding interface function, where the sending function needs an incoming content address and a content length, the receiving function is implemented by an anonymous function, call the received content buffer address and length back to an external service module, and call a connect function to open the long connection channel between the push server and the push server. Specifically, the terminal to be put in calls a connect function to send a TCP or UDP protocol packet to the push server, the push server generates a feedback message after receiving the TCP or UDP protocol packet and returns the feedback message to the terminal to be put in, the terminal to be put in generates a feedback message for the feedback message after receiving the feedback message and returns the feedback message to the push server, and the push server completes the process of establishing a long connection channel after receiving the feedback message.

In some embodiments, at least one connection channel may be set to ensure stability of a transmission process of the pushing server for issuing the file to be released. In particular, the long connection channel may comprise at least one of a primary connection channel or a backup connection channel.

The sending priority may refer to a priority of sending the file to be released to the terminal to be released by using the connection channel, and sending the file to be released to the terminal to be released by using the connection channel with high priority.

Optionally, the main connection channel is a channel for sending files to be released to all the terminals to be released, and the standby connection channel is a channel for sending files to be released to the terminals to be released associated with the standby connection channel.

Optionally, the primary connection channel has a higher transmission priority than the backup connection channel.

For example, the pushing server may include at least one of a main server and a proxy server, where the main server can send files to be released to all terminals to be released, a connection channel between the main server and the terminals to be released is a main connection channel, the proxy server can send files to be released to the terminals to be released associated with the main server and the proxy server can send files to be released to the terminals to be released, and the connection channel between the proxy server and the terminals to be released is a standby connection channel.

For example, if the push server is a main server, after the configuration server generates the file to be released, the file to be released may be sent to the main server, and sent by the main server to each terminal to be released through the main connection channel. If the push server is a proxy server, a plurality of proxy servers may be set as the push server, each proxy server is associated with a different terminal to be put, and different terminals to be put may be divided according to a type of an operating program, an operating system type, and the like, for example, a proxy server a is associated with a terminal to be put of the operating system a, a proxy server B is associated with a terminal to be put of the operating system B, a proxy server C is associated with a terminal to be put of the operating system C, and the like. Therefore, after the configuration server generates the file to be released, the file to be released can be sent to the proxy server corresponding to the terminal information through the standby connection channel according to the terminal information carried in the file to be released, and then the proxy server sends the file to the corresponding terminal to be released, so that the file to be released is distributed to different types of terminals to be released through a plurality of proxy servers.

Alternatively, if the long connection channel includes a plurality of connection channels, when the long connection channel is established, the connection channel may be established from high to low according to the transmission priority, so that the connection channel of high priority can be established and used first.

In some embodiments, two connection channels with different priorities may be established between the push server and the terminal to be released, so as to ensure stability of the push server in issuing the file to be released. In particular, the long connection channels may include a primary connection channel and a backup connection channel.

For example, the pushing server may include a main server and a proxy server, and may preferentially use the main server to send the file to be released to the terminal to be released through the main connection channel, if feedback information of the file received by the terminal to be released is not received within a preset period of time, the main connection channel is indicated to be unavailable, and at this time, the file to be released may be sent to the terminal to be released again through the proxy server through the standby connection channel.

In some embodiments, the server may verify whether the connection channel is available each time the file to be released is sent to the terminal to be released, and if so, issue the file to be released again, so that errors in issuing the file can be avoided. Specifically, the sending the file to be released to the terminal to be released may include:

verifying a long connection channel;

and if the verification is passed, sending the file to be released to the terminal to be released through the long connecting channel.

For example, the long connection channel can be used for transmitting and receiving data such as messages or files between the delivery server and the terminal to be delivered, if the data can be successfully transmitted and received, the long connection channel is available, the next step is carried out, if the long connection channel cannot be used, the long connection channel is unavailable, and the process is ended.

Optionally, the long connection channel may be verified before step 150, for example, when the multimedia content and the delivery policy of the multimedia content are acquired, that is, the long connection channel may be verified, and in the process of generating the file to be delivered, for example, steps 120 to 130, the long connection channel may be verified at the same time, and then the available long connection channel is selected according to the verification result to send the file to be delivered.

Optionally, when the long connection channel includes a plurality of connection channels, the priori certificate sends the connection channel with high priority, after verification, the connection channel with high priority is used to send the file to be released to the terminal to be released, if the sending fails, the connection channel with low priority is verified again, and after verification, the connection channel with low priority is used to send the file to be released to the terminal to be released. For example, the main connection channel is verified a priori, and if the main connection channel fails to send, the standby connection channel associated with the terminal to be put in is verified.

In some embodiments, message authentication may be performed between terminals to be delivered through a server to verify the availability of a connection channel. Specifically, verifying the long connection channel may include:

sending a message to be verified to a terminal to be put in through a long connection channel;

and acquiring a verification result of the to-be-released terminal to-be-verified information, and verifying the verification result.

For example, when the push server sends a file to be released to the terminal to be released, a message (the message may be an equation or a function with parameters for verifying the security of data transmission) needing a calculation result may be sent to the terminal to be released through the push server, the terminal to be released decrypts the message and calculates a message result, the message result is returned to the push server through the sending function, the push server receives the message result and then locally checks a signature, and after the signature passes, a long connection channel between the terminal to be released and the push server indicating the current period is available, so that the file to be released may be sent to the terminal to be released through the long connection channel; if the check mark does not pass, ending the release process.

Optionally, the issued file to be issued may be encrypted, so as to increase the security of the issued file. Specifically, the sending the file to be released to the terminal to be released may include: and encrypting the file to be released to obtain a processed file to be released, and sending the processed file to be released to the terminal to be released.

For example, the file to be released can be encrypted by an encryption and decryption algorithm in a sockaddr_in structure pointer. When the terminal to be released receives the processed file to be released, the file can be decrypted first, if the decryption is successful, the file is read, and if the decryption is failed, the flow is ended.

In some embodiments, before the connection channel between the server and the terminal to be put in is established, application information verification may be performed in advance to increase the reliability of the connection channel. Specifically, before the long connection channel is established, the method may further include:

when a terminal to be put in starts an application program for the first time, acquiring application information of the application program;

verifying application information;

and if the verification is passed, generating a terminal identifier of the terminal to be put in, and sending the generated terminal identifier to the terminal to be put in.

The application information may refer to information of an application program, for example, the application information may include, but is not limited to, at least one of an application ID, a certificate, and description information, etc.

Wherein the terminal identity may refer to a representation, such as a token, generated by the server to indicate the identity of the terminal. token refers to a token in computer authentication that can represent an object of rights to perform certain operations.

For example, when the user agrees, information generated when the user registers an application, such as an application ID, a certificate, and description information, may be acquired as application information, and when the application is started for the first time, the terminal transmits the application information to the push server. After receiving the application information, the pushing server internally associates with a configuration platform carried by the configuration server to carry out authentication, if the authentication is successful, a token is generated and put into the application program, the generated token can identify the uniqueness of the application program, and the version of the application program is not limited.

Optionally, after generating the terminal identifier of the terminal to be released and sending the generated terminal identifier to the terminal to be released if the verification is passed, the method may further include: and storing terminal information of the terminal to be put in and attribute information of a user using the terminal to be put in. For example, after receiving the terminal identifier, the terminal to be delivered may send the terminal information and the attribute information of the user using the terminal to the configuration server for storage. In this way, the terminal associated with the server may be determined through an authentication process.

Optionally, in order to make the configuration platform learn the terminal where the application program with successful authentication is located, the terminal to be delivered may forward the terminal identifier to the configuration server. Specifically, after generating the terminal identifier of the terminal to be released and sending the generated terminal identifier to the terminal to be released, the method may further include: and acquiring a terminal identifier sent by the terminal to be released through a configuration server. For example, after receiving a token, an application on a terminal to be launched may send the token to a configuration server.

In some embodiments, after receiving the file to be released, the terminal to be released can intelligently manage the file to be released according to the releasing time carried by the file to be released, so as to reasonably manage the file to be released stored locally and improve the utilization rate of local resources of the terminal to be released. Specifically, after sending the file to be released to the terminal to be released, the method may further include:

when the to-be-released terminal receives the to-be-released file, the to-be-released file is stored in the local storage of the to-be-released terminal;

when the terminal to be released starts an application program, preloading multimedia content to be displayed from a locally stored file to be released so as to display the multimedia content to be displayed according to the releasing time, wherein the multimedia content to be displayed comprises multimedia content with the releasing time meeting a preset time condition.

The preset time condition may be that the delivery time is located after the current time, or that the end time in the delivery time is located after the current time, or the like. In this way, the multimedia content to be displayed can characterize multimedia content determined from the delivery time, which can be displayed at the present time and after the present time.

For example, after the to-be-launched terminal receives the issued to-be-launched file, an application program on the to-be-launched terminal may cache the to-be-launched file locally. The to-be-launched terminal can locally cache a plurality of to-be-launched files, and after the to-be-launched terminal starts an application program, to-be-launched multimedia content with the closest to the current time in the launching time can be extracted according to the launching time of the to-be-launched files, and loaded in the memory, and when the display condition is triggered, the to-be-launched multimedia content can be read, rendered and displayed from the data loaded in the memory.

In some embodiments, the out-of-date file of the local cache may be cleared according to the delivery time, so as to improve the utilization rate of the local resource of the terminal to be delivered. Specifically, after sending the file to be released to the terminal to be released, the method may further include: deleting the locally stored expiration file according to the release time, wherein the expiration file comprises a file to be released, and the release time is the time before the current time. For example, when the to-be-launched terminal receives the to-be-launched file, the to-be-launched terminal can check whether an expired to-be-launched file exists in the local cache, and if so, an asynchronous thread can be started for cleaning.

Optionally, when the to-be-launched terminal receives a new to-be-launched file, the over-period file of the local cache can be cleaned immediately, so that the utilization rate of the local resource of the to-be-launched terminal is improved. Specifically, deleting the locally stored expiration file according to the delivery time may include: when the to-be-released terminal receives the to-be-released file, if the to-be-released terminal caches the historical to-be-released file with the same file identification as the received to-be-released file, deleting the historical to-be-released file with the same file identification as the received to-be-released file. For example, the file identification may include a multimedia content type, a multimedia display location, and the like.

Optionally, when the terminal to be released analyzes the received file to be released, only part of the file data can be analyzed for caching the file, so that the analysis efficiency is improved. Specifically, storing the file to be released in the local storage of the terminal to be released may include: analyzing a preset field positioned at the head of the file to be released to obtain an analysis result; and storing the file to be released in the local storage of the terminal to be released according to the analysis result.

For example, after the terminal to be released receives the issued file to be released, the application program on the terminal to be released can analyze only the key fields of the file header, such as the buffer time, the buffer mode, the release time, and the like, and other fields, such as the multimedia content field, the display mode, the display trigger condition, and the like, are not analyzed at this stage. When the files to be released are stored, the files to be released can be cached locally according to the analysis to obtain the caching time, the caching mode and the like, when the multimedia content is displayed or the out-of-date files are deleted, whether the multimedia content of the files to be released is required to be displayed can be judged according to the analysis to obtain the releasing time, if so, the fields related to the multimedia content in the files to be released can be continuously analyzed to read, render and display, or whether the files to be released are the out-of-date files to be deleted is judged, and if so, the files to be released are deleted.

The multimedia content delivery scheme provided by the embodiment of the application can be applied to various content pushing scenes. For example, taking advertisement delivery as an example, acquiring multimedia content, a delivery strategy of the multimedia content and at least one task object, wherein the delivery strategy comprises delivery time and terminal information of at least one terminal to be delivered, and the number of the task objects is not more than the number of the terminals to be delivered; updating information carried by the task object according to the multimedia content and the delivery strategy to obtain updated information; processing updated information carried by the task object to obtain a to-be-released text corresponding to the terminal information; updating updated information carried by the task object into an initial value so as to use the task object to obtain a file to be released corresponding to the information of the next terminal; and sending the file to be released to the terminal to be released so that the application program running on the terminal to be released displays the multimedia content in the releasing time. According to the scheme provided by the embodiment of the application, when the file to be released is generated, the task object can be reused by updating the information carried by the task object, so that the computing resource is saved.

In addition, after the file to be released is generated, the file to be released can be actively sent to the terminal, so that the releasing flow is simplified, and the computing resources are saved. The file to be released is generated through the multimedia content, the releasing strategy and the task object, and after the terminal receives the file to be released, the multimedia content can be released in real time according to the releasing time in the releasing strategy, so that the timeliness of releasing the multimedia content is improved.

The method described in the above embodiments will be described in further detail below.

In this embodiment, a method according to an embodiment of the present application will be described in detail using multimedia content as an advertisement.

As shown in fig. 2a, the delivery server may include a configuration server and a push server, where the configuration server is equipped with a configuration platform, and the push server may include a main server and a plurality of proxy servers. An SDK for managing advertisement delivery may be integrated into an application running on the terminal.

As shown in fig. 2b, a specific flow of a method for delivering multimedia content is as follows:

200. when the terminal starts the application program for the first time, the application information of the application program is verified through the pushing server and the configuration server.

For example, as shown in fig. 2c, when receiving user consent, the user may register an application through the terminal SDK and generate application information such as an app id, a certificate, and description information unique to the corresponding application for each user. The terminal SDK may send these application information to the push server when the application is first started. After receiving the information, the pushing server (the main server or the proxy server) internally associates with the configuration platform to carry out authentication, if the authentication is successful, a release token is generated and returned to an application program running at a terminal, and after receiving the release token, the application program sends the release token to the configuration server. If the configuration server receives the release token sent by the terminal, the verification is passed, and if the configuration server does not receive the release token, the verification fails, and the process is exited.

In the software development process, a certain general function is involved, and the general function is abstracted into an SDK, for example: sharing function, login, payment, etc. The application process of the multimedia content delivery method described in the embodiment of the application is based on the SDK, and the main functions are to provide personalized advertisement delivery capability in an App, H5 and applet multi-application terminal, support advertisement delivery aiming at a directional crowd, help operators to reach users accurately and timely, and achieve the purposes of retention, activation and service growth. The advertisement types mainly comprise carousel, single graph, popup window, bulletin, list, screen flash, screen cut and the like.

The release server and the configuration server can determine the terminal associated with the release server according to the release token sent by the received terminal, namely, the sent release token is associated with the release server.

210. If the verification is passed, a long connection channel between the delivery server and the terminal is established through the delivery server and the terminal.

As shown in fig. 2a, the long connection path between the delivery server and each terminal may include a main connection path, which is a connection path between the main server and the terminal, and a standby connection path, which is a connection path between the proxy server and the terminal.

For example, as shown in FIG. 2c, after verification passes, the primary connection channel may be established during the installation cycle of the application. The installation cycle of an application may not have the process of the application from installation to uninstallation. For example, after the terminal associated with the main server is started for the first time and passes verification, a long connection channel is established based on an API corresponding to the Socket, and information to be used in the process includes a use protocol, an IP address of the terminal device, a protocol port number, an IP address of a remote server host, a port number of the remote server, and the like.

The specific process for establishing the long connection channel comprises the following steps: the terminal establishes a pass through a socket function, the input parameters are protocol fields (IPV 6 or IPV 4), the protocol types (TCP or UDP) and opens up a client memory address; creating a sockaddr_in structure pointer, including a port and an IP address of a main server and an encryption and decryption algorithm, and calling a connect to open a connection; setting an interface function corresponding to sending and receiving, wherein the sending function needs to transmit the content address and the content length, the receiving function is realized by an anonymous function, and the received content buffer address and the length are returned to an external service module. This procedure can also be used to establish a backup connection channel.

220. And acquiring the multimedia content and the delivery parameters through a configuration server.

For example, when a user wants to deliver advertisements to a terminal used by a target crowd, the multimedia content and delivery parameters can be configured through a configuration platform. The multimedia content can comprise relevant fields such as pictures, videos and texts of advertisement materials, and the delivery parameters can comprise delivery time, target crowd attribute information and the like. The delivery time may be an effective period of the application of the advertisement at the terminal. The user-set multimedia content may include advertising material for one or more advertisements.

230. And determining a delivery strategy of the multimedia content through a configuration server, and constructing at least one task object.

For example, after the user completes configuration, the configuration platform stores the delivery task in the configuration server after the configuration is completed, the configuration server counts down through the issuing time, determines the terminals corresponding to the target crowd as the terminals to be delivered according to the attribute information of the target crowd, the number of the terminals to be delivered is m, and obtains the address information of the terminals to be delivered from the database. It can be understood that each to-be-launched terminal corresponds to one pushing task, and m to-be-launched terminals are equivalent to the to-be-launched files corresponding to each to-be-launched terminal through m pushing tasks, and the to-be-launched files are sent to the corresponding to-be-launched terminals so as to complete the launching tasks configured by the user on the configuration platform.

The configuration server can construct m/2 initiator objects to start concurrent threads according to the number m of the terminals to be released, each concurrent thread has a workflow to process the initiator, and each initiator object has three identifiers: the tag task (including the integration information of the advertisement materials), the target communication address (the address of the terminal to be put down) and the information (describing the state information of the Actor in the server) acquired during the communication processing task. the target communication address only contains the address of one terminal to be put in.

The basis of the Actor objects is message passing, and an Actor object may be considered a basic computing unit that can receive messages and perform operations based thereon, and may also send messages to other Actor objects. The Actors are isolated from each other, and do not share memory. According to the method and the device for processing the push task of the configuration server through the Actor object, concurrency and memory cache multiplexing can be improved.

240. And updating the information carried by the task object according to the multimedia content and the release strategy by the configuration server to obtain updated information.

For example, as shown in fig. 2d, the configuration server may extract three pieces of information of the identifier of the initiator object from the database, and assemble the three pieces of information in the initiator object to obtain an assembled initiator object.

250. And processing the updated information carried by the task object through the configuration server to obtain a file to be released corresponding to the terminal information.

For example, m/2 assembled Actor objects are respectively processed through the workflow of m/2 concurrent threads, so that m/2 files to be released are obtained. The files to be released can be in an Xlog format, and mainly comprise advertisement materials, types, texts, displayed UI arrangement, expiration time, effective time and the like, wherein the materials are stored in a base64 mode, and other information is stored in a key-value mode. It can be understood that each process of processing the assembled Actor object is to encapsulate the Actor object into a file to be released. And the steps 240 to 250 are the process of completing one pushing task.

260. And verifying the main connection channel through the push server.

For example, as shown in fig. 2c, before the file to be released is released, a message that needs a calculation result may be sent to the terminal to be released through the main server, where the message may be an equation or a function with parameters, and is used to verify the security of data transmission. After receiving the message, the terminal to be put in decrypts and calculates the message result through the SDK, and transmits the message result to the main server through the transmitting function, the main server locally checks the signature after receiving the message, and the main connection channel between the main server and the terminal to be put in, which indicates the current period after the signature checking is passed, is available. If the signature verification fails, the process is exited. The master server may send the verification signature to the configuration server to instruct the configuration server to send the file to be released to the push server.

270. And if the verification is passed, sending the file to be released to the terminal to be released through the pushing server by using the main connection channel.

For example, after the signature passes, the configuration server may encrypt the file to be released, send the encrypted file to be released to the main server, and send the file to be released to the terminal to be released corresponding to the file to be released through the main connection channel by the main server. If the main server does not receive the feedback information that the terminal to be released is successfully released within the preset time period, the configuration server can send the encrypted file to be released to the proxy server associated with the terminal to be released, and the proxy server sends the file to be released to the terminal to be released corresponding to the file to be released through the main connection channel.

As shown in fig. 2c, the configuration server may send the file to be released to the main server, and then the main server or the proxy server encrypts the file to be released and sends the encrypted file to the terminal to be released.

280. And updating the updated information carried by the task object into an initial value through the configuration server so as to use the task object for obtaining a file to be released corresponding to the information of the next terminal.

For example, as shown in fig. 2d, after the assembled Actor-object finishes processing one push task, the state attribute of the assembled Actor-object is set to be in a multiplexing state, and three identifiers are emptied to process the next push task. And recovering the Actor object to release the memory until all pushing tasks are processed, and when all the terminals to be released receive the files to be released.

290. An application running on the terminal to be released manages the multimedia content.

And the application program running on the terminal to be released can manage the received multimedia content in the file to be released through the SDK according to the information carried by the file to be released. The management means may include, but is not limited to, caching, preloading, displaying, cleaning, etc. As shown in fig. 2e, the manner in which the application manages the multimedia content may include steps 291-295.

291. When the to-be-released terminal receives the to-be-released file, the to-be-released file is stored in the local storage of the to-be-released terminal through the to-be-released terminal.

For example, as shown in fig. 2f, after receiving the issued file to be released on the terminal to be released, after decrypting the file to be released, the field information in the file to be released can be analyzed through the SDK, the file to be released is cached locally, the local cache is used for caching materials by advertisement types and advertisement position IDs, and a plurality of advertisement materials can be cached locally.

292. When the terminal to be released starts an application program, the multimedia content to be displayed is preloaded from the locally stored file to be released through the terminal to be released.

For example, after the terminal to be released starts the application program, as shown in fig. 2f, the application program may take out the corresponding advertisement material through the SDK according to the effective period of the advertisement in the local data and load the advertisement material into the memory, and the caller may read, render and display at any time.

293. And displaying the multimedia content to be displayed according to the delivery time through the terminal to be delivered.

For example, as shown in fig. 2f, when the delivery time is reached, a module of an application running on the terminal to be delivered may call the display interface to read the preloaded multimedia content from the memory through the SDK, and render and display the multimedia content to be displayed according to the read data.

294. And deleting the historical files to be released, which are the same as the file identifiers of the received files to be released, through the terminals to be released.

For example, if the advertisement material is cached, the coverage operation is directly performed if the advertisement material has the same advertisement position ID as the advertisement material in the currently received file to be released.

295. And deleting the locally stored expiration file according to the release time by the terminal to be released.

For example, as shown in fig. 2f, after the terminal to be released receives the issued file, the terminal may check that the local cache has outdated advertisement material through the SDK, and start an asynchronous thread to clean. The cleaned expiration files can be stored in other cache areas in the terminal to be released and then deleted.

In the prior art, as the functions of the application program are gradually perfected, the requirement on the update frequency of the delivery is higher and higher, and the delivered content has important significance on the retention of users and the conversion of the users, so that the timeliness of the advertisement is required to be improved.

For example, the client a puts a splash screen advertisement into the terminal, the splash screen advertisement is also called a start screen advertisement, the display time is displayed between when the client starts the APP and when the top page loading is completed, the downloading time of the material is after the client starts, and the display time of the advertisement is next start, because the splash screen advertisement material is locally available when the client starts next time. In this case, there is a problem: if the display logic of the flash advertisement put in is displayed only on a certain day, the advertisement activity disappears after the day, but the application program is actually started only once on the terminal on the day, which is equivalent to only triggering the downloading logic of the material, and then the application program is started for the second time after a few days, and the advertisement material cached last time is displayed, so that the marketing activity fails.

As can be seen from the above, in the embodiment of the present application, after the file to be released is generated, the file to be released may be actively sent to the terminal, so as to simplify the releasing flow and save computing resources. The file to be released is generated through the advertisement materials, the releasing strategy and the task object, and after the terminal receives the file to be released, the advertisement materials can be released in time according to the releasing time in the releasing strategy, so that the timeliness of releasing the advertisement materials is improved.

In addition, by adopting two long connection schemes of the main connection channel and the standby connection channel, the stability and the certainty of the issued advertisement materials are improved, and the two connection channels all need authentication, authentication and encryption and decryption operations, so that the safety of data is ensured. The configuration server processes the push task by adopting the Actor object, and the state attribute of the Actor object is increased, so that the stability under high concurrency can be ensured, and the Actor in the multiplexing state saves the memory overhead of the object. The terminal reasonably manages the advertisement materials through the SDK, and cleans the expired advertisement materials under the condition of ensuring that the running of the program is not influenced.

In order to better implement the above method, the embodiment of the application also provides a multimedia content delivery device, which can be specifically integrated in an electronic device, and the electronic device can be a terminal, a server or other devices. The terminal can be a mobile phone, a tablet personal computer, an intelligent Bluetooth device, a notebook computer, a personal computer and other devices; the server may be a single server or a server cluster composed of a plurality of servers.

For example, in the present embodiment, a method of the embodiment of the present application will be described in detail by taking a specific integration of the multimedia content delivery device in a server as an example.

(IV) transmitting unit 340

The method can be used for sending the file to be released to the terminal to be released so that the application program running on the terminal to be released can display the multimedia content in the releasing time.

In some implementations, the sending unit 340 may also be configured to:
