Detailed Description

So that the manner in which the features and elements of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

It should be noted that in the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

Currently, internet companies are crossing operators, developing various video and data service services (OTT) based on The open internet more and more deeply into The daily work and life of users, providing various application services to The users through The internet, and such applications are different from The communication services currently provided by operators, which only utilize The network of The operators, and The services are provided by third parties other than The operators. At present, typical OTT services are OTT video, apple app stores, and the like.

Through careful study, the applicants have found that: the current OTT system can be categorized into the following two types:

the first category, which limits the content to be played, such as video, before playing, mainly shows the following ways: the content presentation is controlled in a user grouping mode, specifically, the users are divided into several groups according to categories such as tourists, members, VIPs (very important persons), gold members and the like, and the content presented to the users is controlled according to the watching authority of the users in each group on the played content.

And in the second category, the content presentation is controlled in a terminal implementation manner, specifically, an original video stream audio played before the terminal is closed, and a specific still picture or video is displayed in an overlaid manner on the original video stream, so as to implement the control on the content presentation.

For the first type of mode, users are only roughly divided into several groups, and the conditions for group division are relatively single, so that the content presentation control is extensive, and each group cannot be flexibly adjusted according to the requirements of the users, so that the content presentation cannot be flexibly controlled.

In addition, for the second type of mode, it can be understood that the terminal controls the playing of the video stream according to the policy, and the terminal needs to be modified once every time a limit is added to the policy, which results in high implementation complexity and high cost of the method; the restriction strategy of the terminal usually appears at a certain time and cannot be immediately effective, so that the real-time performance of the method is poor; in practical application, when the video stream is limited to play, the video stream is actually pulled down to the terminal, so that the display of the video stream cannot be effectively controlled, especially the time-shifted or review video stream cannot be effectively controlled, and the security is poor. It can be seen that the second type of implementation is costly and unsafe.

However, in practical applications, content operators have complex requirements for content presentation, such as restrictions on conditions of playing areas, playing time periods, and the like of the content, and at this time, the content presentation needs to be flexibly, effectively, and accurately controlled according to the complex requirements. Obviously, in the related art, a solution that can realize flexible, effective and accurate control of content presentation to meet the complex requirements of content operators is not provided at present.

Based on this, in various embodiments of the present application, by analyzing the display limited policy related information in the play request URL, generating a first playlist file based on the display limited policy related information, and implementing dynamic display of content at a content play source (e.g., a CDN control system side) through the first playlist file, the play display of output content, such as a media stream, can be flexibly, effectively, and accurately controlled, and the complex requirements of a content operator are met.

The following describes the implementation process of the control method shown in the embodiment of the present application with reference to the accompanying drawings.

Fig. 1 is a schematic view of an implementation flow of a control method for Content presentation at a server side according to an embodiment of the present application, where the control method for Content presentation is applicable to a server, such as a Content Delivery Network (CDN) control server, and as shown in fig. 1, the implementation flow of the control method for Content presentation provided in the embodiment of the present application may include the following steps:

step S101: and receiving a playing request URL sent by the terminal.

Here, the play request URL is used to indicate a data source address of the content of the play request. The terminal may include, but is not limited to, an electronic device with a player, such as a smart phone, a tablet computer, a palmtop computer, and the like.

Step S102: and analyzing the playing request URL to obtain the relevant information of the display restricted strategy carried in the playing request URL.

In practical application, when the server receives the play request URL sent by the terminal and analyzes the play request URL, because the play request URL is configured with a limited condition of the current content display, that is, the play request URL carries the display limited policy related information for the play content, the display limited policy related information of the play content can be conveniently obtained by analyzing the play request URL. The playing content may include a video, a still picture, and the like, and the video may be an OTT video.

Here, the presentation limitation policy-related information of the play content includes at least one of: grouping users; terminal characteristic information; a playing area; playing a channel; play time period, etc.

Wherein the terminal feature information includes at least one of: a terminal IP section; terminal type, etc.

Specifically, the terminal IP segment refers to segment IP geographic information to which the IP address of the terminal belongs, for example, geographic information with segment IP1 of 1.1.1.0 to 1.1.1.255 corresponds to shenzhen city in Guandong province, geographic information with segment IP2 of 1.1.3.0 to 1.1.3.255 corresponds to Dongguan city in Guandong province, and if the IP address of the current terminal is 1.1.1.201, it can be determined that the IP address of the current terminal belongs to segment IP 1. For the terminal type, the terminal may be divided into a terminal supporting an Android (Android) system and a terminal supporting an iOS system according to a difference of operating systems supported by the terminal.

Of course, it is understood that, in practical applications, the terminal type is not limited to the above-mentioned division type, and this is not further limited by the embodiment of the present application.

Step S103: and generating a first playlist file according to the display limited strategy related information.

Step S104: and sending the first playlist file to the terminal.

Here, the first playlist file is used to control a content playback presentation of the terminal. In other words, the server sends the generated first playlist file to the terminal, so that the terminal performs playback display based on the received first playlist file request.

In some embodiments, the first playlist file may be represented by a file in an M3U8 format, but is not limited to a file in an M3U8 format, and may also be represented by a file in another format, which is not limited herein.

In practical application, when the first playlist file is represented in M3U8 format, the entity file that the terminal requests to select from the first playlist file for playing, that is, the content of the file that is actually played, may be stored in the server in the form of fragments.

In practical application, the server, such as the CDN control server, needs to obtain a display limited policy for the played content that is synchronized by the limited policy management server, so that the CDN control server generates the first playlist file according to a matching result of the display limited policy related information and the display limited policy, thereby controlling content playing and displaying of the terminal.

Based on this, in some embodiments, as shown in fig. 2, fig. 2 is a schematic implementation flow diagram of another content presentation control method on the server side provided in the embodiment of the present application, and the method may further include:

step S105: and acquiring the configured display limited strategy aiming at the played content.

Here, the display restricted policy is pre-configured by the restricted policy management server according to the requirement of the content operator, and is synchronized to the CDN control server in real time after configuration is completed. That is to say, the step of obtaining the exhibition limited policy by the CDN control server actually obtains the exhibition limited policy preconfigured by the limited policy management server for the CDN control server.

Here, the presentation limitation policy may include a first limitation condition and a second limitation condition.

The first limited condition is used for representing a limited condition set based on characteristic information corresponding to a user, for example, the limited condition is set based on an audience range of content, or is set based on a terminal held by the user, and the first limited condition may include user group limitation; the terminal characteristic information is limited; limited playing area, etc.; the second limited condition is used to indicate a limited condition set based on user requirements, for example, set based on a requirement of a user wishing to view content in which time period, or set based on a requirement of a user wanting to view content of which channel, and the like, and may include a play channel limitation and a play time period limitation.

Here, the terminal characteristic information limitation includes a terminal IP section limitation and a terminal type limitation.

In practical application, the display limitation strategy can be a flexible combination of multiple limitation conditions so as to meet the complex requirements of content operators and expand the application range.

It should be noted that, in the embodiment of the present application, the execution sequence of step S101 and step S105 is not limited, for example, step S105 may be executed first, and then step S101 is executed, that is, the server acquires the display restricted policy first, then receives the play request URL sent by the terminal, and analyzes the play request URL to obtain the information related to the display restricted policy (as shown in fig. 2); for another example, step S101 may be executed first, and then step S105 may be executed, that is, the server receives the play request URL sent by the terminal first, analyzes the play request URL, obtains the relevant information of the display restricted policy, and then obtains the display restricted policy.

In some embodiments, the specific implementation process of generating the first playlist file according to the information related to the display restricted policy in step S103 may include:

and generating a first playlist file according to the matching result.

In practical application, in the process of generating the first playlist file according to the matching result, when the matching result meets different limited conditions, the process of generating the first playlist file by the server is also different. Accordingly, there is also a difference in the contents of the first playlist file generated by the server.

Based on this, in some embodiments, the generating a first playlist file according to the matching result includes:

That is to say, when a server, such as a CDN control server, matches the information related to the exhibition-restricted policy with the exhibition-restricted policy, if it is determined that the matching result meets a first restricted condition, that is, the matching result is at least one of user grouping restriction/terminal feature information restriction/play area restriction, in other words, the content operator restricts at least one condition of a play-oriented object, a play terminal, and a play area of the content, at this time, the CDN control server generates a first playlist file corresponding to the first specific content, and returns the first playlist file corresponding to the first specific content to the terminal.

Here, the first specific content is used to indicate a limited user group, terminal characteristic information, and content allowed to be played in the playing area, that is, replacing the playing content corresponding to the limited user group, terminal characteristic information, and playing area. For example, if it is determined that a certain video content a is not allowed to be played in the area a, a first specific content, such as a video content B, generated by the CDN control server can be played in the area a, and the video content a is replaced with the video content B; that is, the video content B is a content permitted to be played in the area a.

The first specific content may be a default content of the system, or may be a content determined by the server according to needs, for example, a content corresponding to the display restricted policy configuration, which is not further limited in the embodiment of the present application.

In practical application, the CDN control server may flexibly modify the first specific content as needed.

In some embodiments, the generating a first playlist file according to the matching result includes:

That is to say, when the CDN control server matches the information related to the display restricted policy with the display restricted policy, if it is determined that the matching result meets a second restricted condition, for example, the matching result is that the playing time period is restricted, in other words, the content operator does not allow the content to be played in a specific time period, at this time, the CDN control server generates a first playlist file according to a relationship between a playing time point of a fragment included in the currently-played playing content and the second restricted condition, and a relationship between a current time point of sending the play request URL and the second restricted condition, and returns the generated first playlist file to the terminal.

The following describes the above process of generating the first playlist file in detail for some cases where the second limited condition is that the playing time period is limited.

Case 1:

in some embodiments, the generating the first playlist file according to a relationship between a playing time point of a clip included in the currently playing content and the second limited condition, and a relationship between a current time point of sending the play request URL and the second limited condition includes:

and when the current time point for sending the play request URL is not matched with the limited play time period and the play time point of the fragment contained in the play content which is played currently is not matched with the limited play time period, generating a first play list file corresponding to fourth specific content.

Here, the fourth specific content is used to indicate content allowed to be played for a limited period of time. The fourth specific content may be a default content of the system, or may be a content determined by the server according to needs, which is not further limited in the embodiment of the present application.

For example, the limited playing time period is 9:00 to 10:00 of the morning, it is assumed that the current time point of sending the playing request URL is 8:56 of the morning, the playing time point of the segment included in the currently playing content is 10:05 of the morning, obviously, the time point 8:56 of sending the playing request URL is not within the limited playing time period 9:00 to 10:00, and the time point 10:05 of the playing segment is not within the limited playing time period 9:00 to 10:00, at this time, the CDN control server directly returns the generated first playlist file corresponding to the fourth specific content to the terminal.

Case 2:

Here, the second specific content is used to represent content that is allowed to be played for a limited period of time. The second specific content may be a default content of the system, or may be a content determined by the server according to needs, which is not further limited in the embodiment of the present application.

For example, the limited playing time period is 9:00 to 10:00 of the morning, it is assumed that the current time point of sending the playing request URL is 8:56 of the morning, and the playing time point of the partial segment included in the currently playing content is between 8:59 to 9:10 of the morning, and it is obvious that the time point 8:56 of sending the playing request URL is not within the range of the limited playing time period 9:00 to 10:00, but there is an intersection between the time point of the played partial segment and the limited playing time period 9:00 to 10:00, at this time, the CDN control server replaces the segment corresponding to the intersection, that is, 9:00 to 9:10, with the segment corresponding to the second specific content, to generate the first playlist file.

Case 3:

wherein the third specific content is used for representing the content allowed to be played within the second limited condition, that is, for representing the content allowed to be played for a limited period of time.

Here, the third specific content may be a content default to the system, or may be a content determined by the server according to needs, which is not further limited in this embodiment of the application.

For example, the limited playing time period is 9:00 to 10:00 of the morning, it is assumed that the current time point of sending the playing request URL is 8:56 of the morning, and the playing time point of a part of the segments included in the currently playing content is between 9:00 to 10:30 of the morning, it is obvious that the time point 8:56 of sending the playing request URL is not within the range of the limited playing time period 9:00 to 10:00, but there is an overlapping portion between the time point of the played part of the segments and the limited playing time period 9:00 to 10:00, at this time, the CDN control server replaces the segments corresponding to the overlapping portion, i.e., 9:00 to 10:00, with the segments corresponding to the third specific content, and retains the segments of the original content for the non-overlapping portion, i.e., the segments corresponding to 10:01 to 10:30, so as to generate the first playlist file.

Case 4:

and when the current time point of the URL sending the playing request is matched with the limited playing time period and the playing time point of the segment contained in the playing content currently being played is not matched with the limited playing time period, replacing the segment not matched with the limited playing time period with the segment corresponding to the original playing content to generate the first playlist file.

For example, the limited playing time period is 9:00 to 10:00 of the morning, it is assumed that the current time point of sending the playing request URL is 9:02 of the morning, and the playing time point of the segment included in the playing content being currently played is 10:05 of the morning, and obviously, the time point 9:02 of sending the playing request URL is within the range of the limited playing time period 9:00 to 10:00, but the time point 10:05 of the playing segment is not within the range of the limited playing time period 9:00 to 10:00, at this time, the CDN control server replaces the segment that does not match the limited playing time period with the segment corresponding to the original playing content, and generates the first playlist file.

Case 5:

and when the current time point of the URL sending the playing request is matched with the limited playing time period and the playing time point of the sub-piece contained in the playing content which is currently played is matched with the limited playing time period, generating a first playlist file corresponding to fifth specific content.

Here, the fifth specific content may be a content default to the system, or may be a content determined by the server according to needs, which is not further limited in this embodiment of the application.

For example, the limited playing time period is 9:00 to 10:00 of the morning, it is assumed that the current time point of sending the playing request URL is 9:02 of the morning, and the playing time point of the segment included in the playing content being currently played is between 9:05 to 9:20 of the morning, and obviously, the time point 9:02 of sending the playing request URL is within the range of the limited playing time period 9:00 to 10:00, and any one of the time points 9:05 to 9:20 of the playing segment is also within the range of the limited playing time period 9:00 to 10:00, at this time, the CDN control server generates the first playlist file corresponding to the fifth specific content, and returns the generated first playlist file corresponding to the fifth specific content to the terminal.

It should be specifically noted that the second specific content, the third specific content, the fourth specific content and the fifth specific content in the embodiments of the present application may be the same (including all the same and part of the same), or may be different, and are not further limited herein.

The content display control method provided by the embodiment of the application is based on the display limited strategy related information carried in the play request URL to generate the first play list file, dynamic display of the content at the content play source end is realized through the first play list file, and the output content such as media stream can be flexibly, effectively and accurately controlled to be played and displayed, so that the content presentation mode is enriched while the safety, the real-time performance and the accuracy are ensured, the complex requirements of content operators are met, and the user experience is improved.

Fig. 3 is a schematic view of an implementation flow of a control method for content presentation according to an embodiment of the present application, and as shown in fig. 3, the implementation flow of the control method for content presentation according to the embodiment of the present application may include the following steps:

step S301: the terminal sends a play request URL to the server.

Here, when a user using a terminal wants to view a play content such as a video, a play request URL is transmitted to a server through the terminal, wherein the play request URL can be carried in a play request message.

Step S302: and the server receives a playing request URL sent by the terminal.

Step S303: and the server analyzes the playing request URL to obtain the relevant information of the display limited strategy carried in the playing request URL.

In practical application, the related information of the display limited strategy can be set by the limited strategy management server based on the characteristic information corresponding to the user or the user requirement, and after the setting of the limited strategy management server is completed, the related information of the display limited strategy is sent to the terminal, so that when the terminal sends a play request URL to the server, the related information of the display limited strategy can be carried in the play request URL and sent together.

Here, the presentation restricted policy related information includes at least one of: grouping users; terminal characteristic information; a playing area; playing a channel; play time period, etc. Wherein the terminal feature information includes at least one of: a terminal IP section; terminal type, etc.

In some embodiments, before obtaining the information related to the restricted policy for presentation carried in the play request URL, the method may further include: and acquiring the configured display limited strategy aiming at the playing content.

Here, the display restricted policy is pre-configured by the restricted policy management server according to the requirement of the content operator, and is synchronized to the CDN control server in real time after configuration is completed. That is to say, the step of obtaining the exhibition limited policy by the CDN control server may actually obtain, for the CDN control server, the exhibition limited policy preconfigured by the limited policy management server.

Step S304: and the server generates a first playlist file according to the relevant information of the display limited strategy.

In some embodiments, when the server obtains the exhibition-restricted policy, the specific implementation process of step S304 may include:

matching the relevant information of the display limited strategy with the display limited strategy to obtain a matching result; and generating a first playlist file according to the matching result.

Step S305: and the server sends the generated first playlist file to a terminal.

Here, the first playlist file is used to control a content playback presentation of the terminal.

In practical applications, the first playlist file may be represented by a file in the M3U8 format, but is not limited to the file in the M3U8 format, and may also be represented by a file in another format, which is not limited herein.

Step S306: and after receiving the first playlist file, the terminal performs playing display based on the first playlist file request.

In practical application, when the first playlist file is represented in M3U8 format, the entity file that the terminal requests to select from the first playlist file for playing, that is, the file that is actually played, may be stored in the server in the form of fragments.

Here, the step of requesting, by the terminal, to play and present based on the first playlist file may actually request, in sequence, to play and present at least two segment files included in the first playlist file based on the at least two segment files.

Here, the time lengths of the at least two fragmented files may be the same or different, and this is not further limited in this embodiment of the application.

In some embodiments, when the terminal requests a play presentation based on the first playlist file, the method may further include:

monitoring the playing progress of the at least two fragment files;

when the fact that the playing progress of the at least two fragment files reaches a set threshold value is monitored, a playing request URL is sent to the server again; wherein the re-sent play request URL is used to request acquisition of a second playlist file.

That is, when the terminal requests a new playlist file, i.e., a second playlist file, from the server again, steps S301 to S306 may be repeatedly performed to meet the requirement of periodically requesting a new playlist file. Here, the set threshold may be preset as needed, and is not further limited herein.

It should be noted that the specific processing procedure of the server has been described in detail above, and is not described herein again.
