[0049] The following is a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0051] At present, the application of screen projection technology is becoming more and more extensive. Currently, mobile phones, computers, and TVs basically support wireless screen projection protocols (Miracast, Airplay, DLNA, etc.), and various video applications also support wireless screen projection protocols in the video playback window. It has become a habit for users to project the playback content of video applications on their mobile phones to the TV. The core method of current wireless screen projection is to transmit the information on mobile phones and computers to the TV for display through video streams. Specifically, when the user casts the screen, the screen projection display is usually directly based on the user's screen projection data stream. However, when the screen projection display is based on the user's screen projection data stream, the data transmission depends on the stability and bandwidth of the screen projection data stream. When the screen projection data stream is unstable, it may affect the stability, smoothness and clarity of the screen projection display, which is not conducive to improving the display effect and affecting the user's viewing experience.

[0052] At the same time, based on the needs of digital copyright protection and video content operation, the screen projection of some film and television content has been controlled by video content operators (such as not allowing screen projection display, reducing screen projection resolution, etc.), which may affect the user experience of wireless screen projection.

[0053] In order to solve at least one of the above-mentioned technical problems, in the solution of the present application, in response to a screen projection request sent by a screen projection initiator, screen projection information corresponding to the above-mentioned screen projection request is obtained, wherein the above-mentioned screen projection information includes screen projection application information and screen projection content information; the corresponding target application in the screen projection receiving end is determined according to the above-mentioned screen projection application information; and according to the above-mentioned screen projection content information, the screen is projected and displayed through the above-mentioned target application.

[0054] Compared with the prior art, in the solution corresponding to the screen projection control method provided by the present application, the target application installed locally on the screen projection receiving end is determined according to the screen projection application information, so that the screen projection display is performed based on the screen projection content information through the target application installed locally on the screen projection receiving end. Instead of directly performing screen projection display based on the user's screen projection data stream, the display effect does not need to rely on the stability and bandwidth of the screen projection data stream, which is conducive to improving the display effect.

[0055] like Figure 1 As shown, the embodiment of the present application provides a screen projection control method. Specifically, the method includes the following steps:

[0056] Step S100, in response to the screen projection request sent by the screen projection initiator, obtain the screen projection information corresponding to the above screen projection request, wherein the above screen projection information includes screen projection application information and screen projection content information.

[0057] Among them, the above-mentioned screen projection initiator is a smart terminal that initiates the screen projection request, for example, it can be a mobile phone or tablet computer used by the user. In this embodiment, the screen projection initiator is taken as an example of a mobile phone used by the user, but it is not a specific limitation.

[0058] The above-mentioned screen projection request is a request message sent by the screen projection initiator, which is used to establish a relevant connection with the screen projection receiving end to realize screen projection. In this embodiment, the screen projection initiator loads the wireless screen projection protocol, and the wireless screen projection protocol obtains information related to screen projection (such as screen projection application information and screen projection content information), and generates a corresponding screen projection request based on the above information.

[0059] It should be noted that the above-mentioned screen projection information may also include other information, such as the identity information of the screen projection initiator, screen projection setting information (such as screen display ratio, volume, etc.) or other personalized information to provide users with better display effects and viewing experience, which is not specifically limited here.

[0060] Specifically, in response to the screen projection request sent by the screen projection initiator, obtaining the screen projection information corresponding to the screen projection request includes:

[0061] In response to the screen projection request sent by the screen projection initiator, the screen projection request is parsed to obtain the screen projection information included in the screen projection request.

[0062] In an application scenario, the screen projection initiator sends the screen projection request and the screen projection information to the screen projection receiver respectively. When the screen projection receiver receives the screen projection request, it obtains the screen projection information associated with it.

[0063] In an embodiment of the present application, the screen projection initiator integrates the screen projection information into the screen projection request, and the screen projection receiver parses the screen projection request after receiving it to obtain the corresponding screen projection information, thereby ensuring data integrity and improving screen projection accuracy.

[0064] Step S200, determine the corresponding target application in the screen projection receiving end according to the above-mentioned screen projection application information.

[0065] The target application is an application that matches the projection application information from the applications installed locally on the projection receiving end. In one application scenario, a user uses an application to play a video on the projection initiator, and when casting the screen, the same application installed on the projection receiving end is used as the target application.

[0066] Specifically, the above-mentioned screen projection application information includes the application type and application name of the screen projection application;

[0067] The above-mentioned determining the corresponding target application in the screen projection receiving end according to the above-mentioned screen projection application information includes:

[0068] Determine whether the above-mentioned screen projection application belongs to a digital copyright control application according to the above-mentioned application type;

[0069] If the above-mentioned screen projection application is a digital copyright control application, and there is a local application matching the above-mentioned application name in the application library of the above-mentioned screen projection receiving end, the above-mentioned local application will be used as the target application.

[0070] The above-mentioned digital copyright control applications are predetermined applications that require digital copyright management of digital resources provided by the applications. At present, some applications have digital copyright control requirements, while some applications do not. The specific scope of digital copyright control applications can be set and adjusted according to actual conditions and is not specifically limited here.

[0071] Furthermore, the above-mentioned determining the corresponding target application in the screen projection receiving end according to the above-mentioned screen projection application information also includes:

[0072] If the screen casting application is a digital copyright controlled application, and there is no local application matching the application name of the screen casting application in the application library of the screen casting receiving end, an application installation prompt is output;

[0073] In response to the installation trigger instruction of the target object based on the above-mentioned application installation prompt feedback, the above-mentioned screen projection receiving end is controlled to install the target application matching the above-mentioned application name.

[0074] Specifically, if the screen casting application is a digital copyright control application, and there is a local application in the screen casting receiving end that matches the application name of the above-mentioned screen casting application, the local application can be directly used as the target application, or an application existence prompt can be output to the target object (i.e., the user) to remind the user whether to choose to use the local application as the target application. If the user chooses yes, the local application will be used as the target application. Conversely, if the user chooses no, the target application will not be selected, and it will be deemed that there is no target application in the subsequent processing process, and the screen can be cast based on the established screen casting data link.

[0075] If the screen casting application is a digital copyright control application, and there is no local application matching the application name of the screen casting application in the application library of the above-mentioned screen casting receiving end, an application installation prompt is output to remind the user whether to download and install the corresponding application. If the user selects yes (i.e., feedback installation trigger instruction), the screen casting receiving end installs the target application matching the above-mentioned application name. Otherwise, if the user selects no, the corresponding application is not installed, and it is deemed that the target application does not exist in the subsequent processing process, and the screen can be cast based on the established screen casting data link.

[0076] In another scenario, if the screen projection application does not belong to a digital copyright control application, it can also be regarded as that there is no target application, and the screen projection is directly performed based on the established screen projection data link.

[0077] Step S300: Based on the above-mentioned projection content information, projection and display are performed through the above-mentioned target application.

[0078] Specifically, the above-mentioned screen projection content information includes content name and playback status data;

[0079] The above-mentioned screen projection display is performed through the above-mentioned target application according to the above-mentioned screen projection content information, including:

[0080] Determine the target content in the target application that matches the content name;

[0081] Determine the current playback state corresponding to the target content according to the playback state data;

[0082] The target application is controlled to play the target content based on the current playing state.

[0083] Among them, the above-mentioned content name is used to indicate the content that needs to be cast and played, and the above-mentioned playback status data is used to indicate the specific playback status of the relevant content. For example, the above-mentioned content name can be the specific name of a TV series, and the above-mentioned playback status data can include the current episode number, playback progress, etc., which are not specifically limited here. It should be noted that the above-mentioned playback status data can also include information such as playback volume and display brightness to provide users with better personalized display effects.

[0084] Specifically, the above method also includes:

[0085] If the target application does not exist in the screen projection receiving end, determine whether there is a target media resource matching the screen projection content information in the digital copyright media resource library preset in the screen projection receiving end according to the screen projection content information;

[0086] If the target media resource exists in the digital copyright media resource library, output resource prompt information;

[0087] In response to the resource playback instruction fed back by the target object based on the resource prompt information, the screen projection receiving end is controlled to perform screen projection display based on the target media resource.

[0088] Among them, the above-mentioned preset digital copyright media library is a database pre-set in the screen projection receiving end, which stores multiple media resources for which the screen projection receiving end has obtained relevant playback permissions. In the absence of a target application, the screen projection receiving end can play the corresponding resources in the digital copyright media library based on the preset related player (i.e., the playback application). Specifically, the screen projection receiving end outputs resource prompt information to the target object to prompt the user to choose whether to directly play the corresponding resource. If the user chooses yes, the above-mentioned screen projection receiving end is controlled to perform screen projection display based on the above-mentioned target media resource. Otherwise, if the user chooses no, the screen projection can be directly performed based on the established screen projection data link.

[0089] Furthermore, the above method also includes:

[0090] If the target media resource does not exist in the digital copyright media resource library, determine the target data link according to the screen projection request;

[0091] Control the above-mentioned screen projection receiving end to perform screen projection display according to the above-mentioned target data link.

[0092] In one application scenario, a target data link is established between a screen projection initiator and a screen projection receiver according to a screen projection request. The screen projection initiator transmits the content to be displayed to the screen projection receiver based on the target data link, and the screen projection receiver performs screen projection display based on the received data.

[0093] In another application scenario, the screen projection receiving end determines the original address (such as the server that provides cloud resources) of the corresponding content to be played by the screen projection initiating end based on the above-mentioned screen projection request, and establishes a target data link with the original address, thereby directly obtaining the corresponding content based on the original address for display, thereby improving data transmission efficiency and thus improving the screen projection display effect.

[0094] As can be seen from the above, in the screen projection control method provided in the embodiment of the present application, in response to the screen projection request sent by the screen projection initiator, the screen projection information corresponding to the above-mentioned screen projection request is obtained, wherein the above-mentioned screen projection information includes screen projection application information and screen projection content information; the corresponding target application in the screen projection receiving end is determined according to the above-mentioned screen projection application information; and according to the above-mentioned screen projection content information, the screen is projected and displayed through the above-mentioned target application.

[0095] Compared with the prior art, in the solution corresponding to the screen projection control method provided by the present application, the target application installed locally on the screen projection receiving end is determined according to the screen projection application information, so that the screen projection display is performed based on the screen projection content information through the target application installed locally on the screen projection receiving end. Instead of directly performing screen projection display based on the user's screen projection data stream, the display effect does not need to rely on the stability and bandwidth of the screen projection data stream, which is conducive to improving the stability, fluency and clarity of the screen projection display, thereby improving the display effect and thus improving the user's viewing experience.

[0096] In the embodiment of the present application, the above-mentioned screen projection control method is also described in detail based on a specific application scenario. The screen projection control method provided in the embodiment of the present application can realize the digital copyright management of screen projection video based on ecological integration. Specifically, the screen projection protocol of the mobile phone end (i.e., the screen projection initiator) obtains the application information (such as application name, screen projection content information, etc.) involved in the screen projection content, and transmits the information together with the screen projection request to the TV end (i.e., the screen projection receiving end). After the TV end screen projection protocol receives the screen projection request from the mobile phone, it first judges the application information. First, it is judged whether it belongs to the digital copyright protection type. If so, it is judged whether the TV end has installed the application according to the application name. If the TV end has installed the application, it prompts the user that the TV end has installed the application corresponding to the screen projection content, whether to play it through the application on the TV end, and if the user chooses yes, the screen projection content information (such as film and television, TV series name, number of episodes, viewing progress, etc.) is transmitted to the application already installed on the TV end (i.e., the target application), and through the application already installed on the TV end, it jumps to the corresponding screen projection content according to the screen projection content information and displays it. If the application is not installed on the TV, a TV-side content matching query is performed on the media library resources according to the content type (such as film, television, information, office, etc.) of the content projection content information, wherein the resources of the media library include the film, television, music and other content with formal copyrights authorized by the TV manufacturer, and the content types matching the projection content information are film, television, music, etc. If the media library has resources related to the projection content information, the user is reminded that the TV's formal copyright library has corresponding resources and whether to open it through the TV service. If the user chooses yes, the corresponding media (such as film, television, music, etc.) is opened through the TV player according to the projection content information. If there is no projection content information in the TV-side content matching query of the media library resources, the data link of the user's projection request is displayed. It should be noted that in the above judgment process, if the user selects no in any judgment, the data link of the user's projection request is displayed directly according to the projection content operation requirements. For example, if the user selects no when judging whether to open and play the relevant content through the TV application, the data link of the user's projection request is directly displayed according to the projection content operation requirements, and the projection is performed based on the data link.

[0097] Figure 2 is a schematic diagram of a specific process of screen projection display provided by an embodiment of the present application, specifically, Figure 2As shown, the screen projection initiator device (such as a mobile phone) has a built-in wireless screen projection protocol, which has the ability to obtain screen projection content information. After the screen projection protocol stack of the screen projection initiator is started, the screen projection content information analysis module of the screen projection protocol stack is automatically loaded. When the user clicks on the screen projection, the screen projection content information analysis module obtains the screen projection information loaded by the screen projection protocol. The screen projection information may include screen projection application information and screen projection content information. Specifically, the screen projection application information may include application type (digital copyright control type) and application name. The application type and application name can be obtained from the application details of the screen projection initiator. The types of applications include film and television entertainment, information, tools, social, etc. In an application scenario, the application type is the type of application listed on the mall or the application type obtained through the installation information of the application. The list of commonly used application types and their corresponding application names can be maintained through the projection content information analysis module of the projection protocol stack. The information can be updated online from the cloud through the configuration file. The configuration file only needs to configure the application types and application names related to digital copyright protection (digital copyright control type) (such as film and television: Tencent, iQiyi, Youku, Mango TV, etc.; music: QQ Music, NetEase Cloud Music, etc.). Applications not on the list are considered non-controlled types (such as WPS, etc.).

[0098] The information involved in the screen projection content (i.e., screen projection information) also includes screen projection content information, which may include content classification, content name, content data, status data, etc. Specifically, in an application scenario, the above-mentioned screen projection content may specifically include: which application (such as Tencent Video, iQiyi, WPS, etc.) the screen projection data of the screen projection protocol comes from; what is the application name of the application (such as Tencent Video, iQiyi, WPS, etc.); what is the current status of the application, screen projection content information, such as the name of the film or TV series, the number of episodes, viewing progress, etc. For example, the content status of the screen projection is film and television content, Journey to the West, the fifth episode, 35:00 minutes; the complete status of the information is: application type (application type_film and television entertainment, application name_Tencent Video), screen projection content information (content classification_film and television, content name_Journey to the West, content data_fifth episode, status data_current progress 35:00 minutes, etc.).

[0099] In one application scenario, if the screen projection protocol stack belongs to a screen projection request triggered by an internal program of the application (i.e., the screen projection function is built into the application), when the user clicks on the screen projection, the application actively sends the application information related to the screen projection content (such as the application name, screen projection content information, etc.) to the screen projection protocol stack built into the application. In another application scenario, the corresponding information can be actively obtained from the application through the built-in screen projection protocol stack, which is not specifically limited here.

[0100] The user opens an application (such as Tencent Video) on the screen projection initiator (such as a mobile phone) and selects a screen projection receiving device for projection (such as a TV). The screen projection protocol on the screen projection initiator obtains the projection application information and projection content information according to the above steps. The screen projection protocol on the screen projection initiator packages the projection information into a projection request and sends it to the projection receiving end.

[0101] The screen projection receiving end (such as TV) starts, loads the screen projection protocol stack, broadcasts the status information of the screen projection receiving end (such as device name: TV, device ID: TV00001XXY), etc., and receives the screen projection request sent by the screen projection initiator.

[0102] The screen projection receiving end parses the screen projection request, first establishes a screen projection connection with the screen projection initiator according to the screen projection request, and then processes the screen projection information. It should be noted that the screen projection protocol can support two steps at the same time or first process the screen projection information and then establish a screen projection connection based on the digital copyright verification result. That is, when receiving a screen projection request, you can first execute a process based on the screen projection information to determine whether there is digital copyright control content on the screen projection receiving end, and then determine whether to establish a screen projection data link, parse the screen projection data content, and display the screen projection content on the screen projection receiving end based on the result of the process.

[0103] After receiving the screen projection request sent by the screen projection initiator, the screen projection protocol at the screen projection receiving end parses the screen projection information (including screen projection application information and screen projection content information), calls the digital copyright control module of the screen projection protocol stack, and determines whether the screen projection application belongs to the digital copyright control type through the digital copyright control module. If the screen projection application does not belong to the digital copyright control type, it directly parses the data packet of the screen projection link and displays the screen projection request content at the screen projection receiving end. It should be noted that the above-mentioned digital copyright control module can be built into the digital rights management (DRM) module of the screen projection receiving end or the screen projection initiator. If the system has a built-in DRM module, the screen projection protocol only needs to pass the information to the DRM module, and query the digital copyright authorization status based on the DRM module, without the need for the screen projection protocol stack to process.

[0104] If the screen projection application belongs to the digital copyright control type, then check whether the current screen projection receiving end system has installed an authorized application of the digital copyright control type corresponding to the screen projection application (such as movies and TV shows of copyright holders such as Tencent Video, iQiyi, and Youku, which can only be played on this platform). If it has been installed, the screen projection content information is directly passed to the authorized application to play the corresponding content through the authorized application. Specifically, the above-mentioned authorized application can be downloaded in advance from the application store of the screen projection receiving end. If the application store does not have the application, it is downloaded from the digital copyright control platform. Among them, the above-mentioned digital copyright control platform includes the media information and media library authorized by the manufacturer, and the media platform (such as iQiyi's A TV PP software) and media content authorized by the content operator (such as iQiyi's authorized TV player and corresponding film and television content). If the TV end does not have the corresponding authorized application installed, the user is asked whether to download and install it. If the user chooses yes, the corresponding application is downloaded and installed. After installation, the screen projection content information is passed to the authorized application (i.e., the target application), and the corresponding content is played through the authorized application.

[0105] If the projection content corresponding to the current projection application does not have a suitable authorized application of the operator's digital copyright control type to play on the projection receiving end (that is, the operator-authorized broadcast and controllable media platform does not have authorization), then query whether there is authorized content in the manufacturer's digital copyright media library in the digital copyright control platform of the projection receiving end. If the query result is "yes", obtain the projection application content playback address corresponding to the digital copyright media library of the projection receiving end (manufacturer digital copyright media library); the projection protocol stack calls the video player of the projection receiving end and opens the content playback address of the digital copyright media library of the receiving end; the projection content information of the projection initiator is passed to the local player of the projection receiving end, and the corresponding content is played according to the above content playback address and the projection content information of the projection initiator.

[0106] Furthermore, if the digital copyright control platform cannot find the digital copyright of the screen projection application content, it is deemed that the content cannot be directly displayed through the existing resources of the screen projection receiving end, and the screen projection content can be processed and displayed based on the preset copyright protection rules. Among them, the above copyright protection rules can be set and adjusted according to actual needs. For example, it can be set to prohibit screen projection for non-copyrighted content, or reduce the screen projection resolution, etc., which are not specifically limited here.

[0107] When the user switches the projection application and content on the projection protocol request end, the projection protocol stack checks the digital copyright of the projection application content in real time and adjusts the corresponding projection strategy based on the digital copyright verification results.

[0108] The digital copyright management and control platform is dynamically updated based on the digital copyrights obtained by the manufacturer and the digital copyrights authorized by the operator. The manufacturer can adjust the priority of content selection by the projection application on the digital copyright management and control platform (such as giving priority to the manufacturer's digital copyright content for playback, giving priority to content from operators for which membership has been purchased, etc.).

[0109] Thus, in an embodiment of the present application, the screen projection initiator (such as a mobile phone) obtains the corresponding screen projection information (such as application name, screen projection content information, etc.) of the screen projection content, and transmits it to the screen projection receiving end (such as a TV) through the screen projection protocol. If the current screen projection application is a film and television application, the screen projection receiving end queries the copyright information of the TV based on the application information. For example, query whether the current TV has an application for screen projection request, whether the application supports the broadcast control of the screen projection content information, and whether there are resources corresponding to the screen projection content information. Then, by matching the screen projection receiving end with the copyright content of the media resource library, open the content with formal copyright on the TV end to replace the content requested by the user for screen projection. It can protect the rights and interests of large-screen digital copyright operation, and improve the user experience in the screen projection scenario, providing a feasible solution for the operation and protection of digital copyrights of smart TVs.
