Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the inherent logic of the process, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

The technical solution in the embodiment of the present invention is described below with reference to the drawings in the embodiment of the present invention.

As shown in fig. 1, a flow diagram of a screen projection control method according to an embodiment of the present invention is applied to a system including a sending end and a receiving end, and specifically includes the following steps:

step 101: the sending end obtains a first screen projection capability list of the receiving end.

The first screen projection capability list comprises screen projection control capabilities supported by at least one screen projection receiving application installed on the receiving terminal. That is, in one embodiment of the present invention, when a plurality of screen projection receiving applications are installed on the receiving end, screen projection control capabilities supported by the respective screen projection receiving applications are stored in a list. That is, in one embodiment of the present invention, the receiving end provides the delivery end with the delivery control capabilities supported by at least one delivery receiving application installed therein in a list.

It should be noted that the receiving end is an electronic device with a screen projection capability, such as a television, a computer, a projector, and a vehicle-mounted television; the sending end is an electronic device, such as a mobile phone and a tablet computer, which can send screen projection content to the receiving end.

In addition, the screen projection control capability is a large and small screen coordination capability centered on the electronic device. The method can realize the quick, stable and low-delay cooperation of the electronic equipment and the large-screen electronic equipment. For example, the video played by the mobile phone is projected to a television screen to be played, and the capabilities of controlling video fast forward, backward, pause and the like can be realized at the television end.

Step 102: and the sending end determines a first target application supporting screen projection control capacity required by the content to be screen projected according to the first screen projection capacity list.

In this way, when the sending end needs to screen the content to be screened onto the receiving end, the screen-casting control capability required by the content to be screened can be determined, and then a first target application of the screen-casting control capability required by the content to be screened is searched from the first screen-casting capability list.

Step 103: and the sending end indicates the receiving end to call the screen projection control capability of the first target application to control the screen projection of the content to be projected.

After the sending end determines that the screen projection process of the content to be screen projected needs to call the first target application, the sending end can interact with the receiving end to indicate the receiving end to call the screen projection control capability of the first target application installed by the receiving end, and control the screen projection of the content to be screen projected.

As can be seen from steps 101 to 103, in the embodiment of the present invention, the sending end can obtain the first screen-casting capability list of the receiving end, where the first screen-casting capability list includes the screen-casting control capability supported by at least one screen-casting receiving application installed on the receiving end, so as to determine the first target application supporting the screen-casting control capability required by the content to be screen-cast according to the first screen-casting capability list, and further instruct the receiving end to invoke the screen-casting control capability of the first target application to control the screen casting of the content to be screen-cast.

In an optional embodiment of the present invention, the step 101 "the sending end obtains the first screen-casting capability list of the receiving end" includes the following steps a-1 to a-4:

step A-1: the receiving end generates virtual equipment corresponding to a preset screen projection receiving application installed on the receiving end;

step A-2: the method comprises the steps that under the condition that the sending end detects the virtual equipment, the sending end displays first identification information of the virtual equipment;

step A-3: under the condition that the sending end receives a first operation on the first identification information, the sending end responds to the first operation and sends a first capability list request to the receiving end;

step A-4: and the sending end receives the first screen projection capability list sent by the receiving end.

Therefore, in an embodiment of the present invention, when the first identification information (i.e., the identification information of the virtual device corresponding to the preset screen-casting receiving application generated by the receiving end) is displayed on the sending end, if the sending end receives the first operation on the first identification information, the sending end is triggered to send the first capability list request to the receiving end. And after receiving the first capability list request, the receiving end returns the first screen projection capability list to the sending end.

The first operation means that a user subscribes to screen-casting content on a sending end to a receiving end; the first screen projection capability list comprises screen projection control capabilities supported by at least one screen projection receiving application installed on the receiving end. Therefore, in an embodiment of the present invention, a user subscribes to which device to receive content to be screened, and a sending end requests a first screen-casting capability list of the device from which the sending end requests the device.

For example, the sending terminal is a television, the receiving terminal is a mobile phone used by a user, the user uses the mobile phone to connect with the screen-casting television, when first identification information of virtual equipment corresponding to a preset screen-casting receiving application of the screen-casting television is displayed on a screen of the mobile phone, the user can click the first identification information, so that the mobile phone is triggered to send the first capability list request to the screen-casting television, and the screen-casting television sends the first screen-casting capability list to the mobile phone after receiving the first capability list request.

In addition, the preset screen projection receiving application may be one of the screen projection receiving applications installed thereon, for example, a built-in screen projection receiving application of a receiving end; for example, if the receiving end is a screen projection television, the screen projection television may include a built-in screen projection receiving application when it leaves the factory, which may be a preset screen projection application of the screen projection television.

In the prior art, when a screen projection television is installed with screen projection receiving applications other than a built-in screen projection receiving application, and the screen projection television is used for projecting a screen, a plurality of virtual devices corresponding to the screen projection receiving applications are displayed on a screen of an electronic device of a user, so that the user selects which screen projection receiving application corresponding to which virtual device is used for projecting the screen.

In the embodiment of the invention, the receiving end only generates the virtual equipment corresponding to the preset screen projection receiving application, so that the sending end can detect one virtual equipment, and the first identification information of one virtual equipment is displayed, therefore, when the user selects the screen projection equipment on the sending end, the user does not need to consider which one is selected, and the first operation is directly implemented on the first identification information displayed on the sending end, so that the screen projection operation is simplified, and the screen projection experience of the user is improved.

In an optional embodiment of the present invention, the step 102 "the sending end instructs the receiving end to invoke the screen projecting control capability of the first target application, and controls the screen projecting of the content to be projected", includes the following steps B-1 to B-3:

step B-1: the sending end sends a first calling request, wherein the first calling request comprises second identification information of at least one screen projection control capability supported by the first target application;

step B-2: the receiving end receives the first calling request through a preset screen projection receiving application;

step B-3: and under the condition that the first target application is the preset screen projection receiving application, the receiving end calls the screen projection control capability indicated by the second identification information through the preset screen projection receiving application to control the screen projection of the content to be projected.

After the receiving end calls the screen projection control capability indicated by the second identification information through the preset screen projection receiving application, indication information for indicating whether the first calling request is successfully called can be returned to the receiving end.

As can be seen from the above, in an embodiment of the present invention, for the receiving end, the first call request sent by the sending end may be received by the preset screen projection receiving application, so as to determine whether the first target application to be called indicated in the first call request is the preset screen projection receiving application, and if so, the preset screen projection receiving application directly calls the screen projection control capability indicated by the second identification information included in the first call request.

For example, if the receiving end is a screen-casting television, the sending end is a mobile phone, and the application a is a preset screen-casting receiving application, the mobile phone may send a first call request including second identification information of at least one screen-casting control capability supported by a first target application to be called to the screen-casting television. The screen projection television can receive the first calling request through the application A, directly call the screen projection control capability represented by the second identification information in the first calling request when the first target application is the application A, and send a calling result to the mobile phone.

In an optional embodiment of the present invention, in step B-3", the receiving end invokes, through the preset screen-projection receiving application, a screen-projection control capability indicated by the second identification information, and controls the content to be screen-projected after the screen projection, and the method further includes the following step C-1:

step C-1: when the content to be screen-projected is of a first preset type, the receiving end deletes a first target capability corresponding to the preset screen-projection receiving application in the first screen-projection capability list through the preset screen-projection application to obtain an updated screen-projection capability list;

wherein the first target capability comprises: and among the screen projection control capabilities supported by the preset screen projection application, the screen projection control capability which is not supported by the first preset type of the content to be screen projected.

Therefore, after the receiving end calls the screen projection control capability indicated by the second identification information through the preset screen projection receiving application, the receiving end can also judge whether the content to be screen projected is the content of the first preset type through the preset screen projection application, and delete the first target capability corresponding to the preset screen projection receiving application in the first screen projection capability list when the content to be screen projected is the content of the first preset type.

Here, if the first preset type of content to be screen-projected does not support the first target capability, the first target capability cannot be used in the screen-projecting process of the first preset type of content to be screen-projected, and therefore, if the screen-projecting of the first preset type of content to be screen-projected is realized through the preset screen-projecting receiving application, the first target capability corresponding to the preset screen-projecting receiving application in the first screen-projecting capability list may be deleted, so as to achieve an effect of disabling the first target capability of the preset screen-projecting receiving application in the screen-projecting process of the first preset type of content to be screen-projected.

For example, the receiving end is a screen-casting television, the sending end is a mobile phone, and the application a is a preset screen-casting receiving application, after the application a calls the screen-casting control capability indicated by the second identification information, it can be determined whether the content to be screen-cast is live content, and the skip capability of the application a in the first screen-casting capability list is deleted under the condition that the content to be screen-cast is live content, so that the effect of disabling the skip function of the application a in the screen-casting television screen-casting process of the live content is achieved.

It should be noted that the live content does not support the skip capability, and the skip capability includes controlling the progress of the screen-cast content to fast forward and backward.

In an optional embodiment of the present invention, the method further comprises the following step C-2:

step C-2: under the condition that the content to be screen-projected is of a second preset type, the receiving end adds a second target capability corresponding to the preset screen-projection receiving application to the first screen-projection capability list through the preset screen-projection application to obtain an updated screen-projection capability list;

wherein the second target capability comprises: the screen projection control capability supported by the preset screen projection application is not included, and the screen projection control capability supported by the second preset type of the content to be screen projected.

Therefore, after the receiving end calls the screen projection control capability indicated by the second identification information through the preset screen projection receiving application, the receiving end can also judge whether the content to be screen projected is the content of the first preset type through the preset screen projection application, and when the content to be screen projected is the content of the second preset type, the second target capability corresponding to the preset screen projection receiving application is added to the first screen projection capability list.

Here, the second preset type of content to be screen-projected supports the second target capability, but the first screen-projecting capability list does not include the second target capability corresponding to the preset screen-projecting receiving application, and the second target capability needs to be used in the screen-projecting process of the second preset type of content to be screen-projected.

For example, if the receiving end is a screen-casting television, the sending end is a mobile phone, and the application a is a preset screen-casting receiving application, the application a calls the screen-casting control capability indicated by the second identification information, and then can judge whether the content to be screen-cast is on-demand content, and when the content to be screen-cast is on-demand content, add the jump capability corresponding to the application a in the first screen-casting capability list, so as to achieve the effect that the jump capability can be used in the screen-casting process of the screen-casting television on-demand content.

It should be noted that the on-demand content supports the skip capability.

In one embodiment of the present invention, the screen-casting capabilities that need to be changed and correspond to at least one type of screen-casting content can be preset, so that when the screen-casting of the corresponding type of screen-casting content is performed through a preset screen-casting receiving application, the screen-casting control capability supported by the preset screen-casting receiving application in the first screen-casting capability list can be updated to the capability suitable for the corresponding type of screen-casting content, thereby ensuring smooth screen casting, enabling the screen-casting content to achieve an optimal screen-casting effect, and improving the screen-casting experience of a user.

In an optional embodiment of the present invention, in the step 102, "the sending end instructs the receiving end to invoke the screen projecting control capability of the first target application, and controls the screen projecting of the content to be projected", further includes the following steps B-4:

step B-4: and under the condition that the first target application is not the preset screen projection receiving application, the receiving end forwards the first calling request to the first target application through the preset screen projection receiving application so as to call the screen projection control capability represented by the second identification information through the first target application and control the screen projection of the content to be projected.

After the receiving end calls the screen projection control capability indicated by the second identification information through the first target application, indication information for indicating whether the first call request is successfully called can be returned to the sending end.

As can be seen from the above, in an embodiment of the present invention, for the receiving end, the first call request sent by the sending end may be received by the preset screen projection receiving application, so as to determine whether the first target application to be called indicated in the first call request is the preset screen projection receiving application, and if not, the preset screen projection receiving application forwards the first call request to the first target application, so that the first target application calls the screen projection control capability indicated by the second identification information included in the first call request.

For example, if the receiving end is a screen-casting television, the sending end is a mobile phone, and the application a is a preset screen-casting receiving application, the mobile phone may send a first call request including second identification information of at least one screen-casting control capability supported by a first target application to be called to the screen-casting television. The screen projection television can receive the first calling request through the application A, and when the first target application is not the application A, the application A forwards the first calling request to the first target application, so that the first target application calls the screen projection control capability indicated by the second identification information included in the first calling request, and sends a calling result to the mobile phone.

In an optional embodiment of the present invention, after the step B-4 "invoking the screen projecting control capability indicated by the second identification information through the first target application", the method further includes the following steps D-1 to D-2:

step D-1: when the content to be screen-projected is of a first preset type, the receiving end deletes a third target capability in screen-projecting control capabilities supported by the first target application through the first target application, and sends a first capability update indication to the preset screen-projecting receiving application, where the first capability update indication is used to indicate to delete a third target capability corresponding to the first target application, and the third target capability includes: among screen projection control capabilities supported by the first target application, the screen projection control capability which is not supported by the first preset type of the content to be screen projected;

step D-2: and the receiving end receives an application through the preset screen projection, and deletes the first target capability corresponding to the first target application in the first screen projection capability list according to the first capability updating indication to obtain an updated screen projection capability list.

Therefore, after the receiving end calls the screen projection control capability indicated by the second identification information through the first target application, the receiving end can also judge whether the content to be screen projected is the content of the first preset type through the first target application, and when the content to be screen projected is the content of the first preset type, delete the third target capability in the screen projection control capability supported by the first target application, and instruct the preset screen projection application to delete the third target capability corresponding to the first target application in the first screen projection capability list by the first target application.

Here, if the first preset type of content to be projected does not support the third target capability, the third target capability cannot be used in the screen projecting process of the first preset type of content to be projected, so that if the screen projecting of the first preset type of content to be projected is implemented by the first target application, the third target capability in the screen projecting control capabilities supported by the first target application may be deleted (that is, the third target capability in the screen projecting control capabilities supported by the first target application stored inside the first target application is deleted), and the third target capability corresponding to the first target application in the first screen projecting capability list is deleted, so as to achieve an effect of disabling the third target capability of the first target application in the screen projecting process of the first preset type of content to be projected.

For example, the receiving end is a screen-casting television, the transmitting end is a mobile phone, the application a is a preset screen-casting receiving application, and the application B is a first target application, after the application B calls the screen-casting control capability indicated by the second identification information, it can be determined whether the content to be screen-cast is live content, and in the case that the content to be screen-cast is live content, the application B can delete the jump capability in the screen-casting control capability supported by the application B stored inside the application B, and notify the application a to delete the jump capability of the application B in the first screen-casting capability list, so as to achieve the effect of disabling the jump function of the application B in the screen-casting television screen-casting process of the live content.

In an optional embodiment of the present invention, the method further comprises the following steps D-3 to D-4:

step D-3: when the content to be screen-projected is of a second preset type, the receiving end adds a fourth target capability to the screen-projecting control capability supported by the first target application through the first target application, and sends a second capability update instruction to the preset screen-projecting receiving application, where the second capability update instruction is used to instruct to add a fourth target capability corresponding to the first target application, and the fourth target capability includes: the screen-casting control capability supported by the first target application is not included, and the screen-casting control capability not supported by the second preset type of the content to be screen-cast is not included;

step D-4: and the receiving end receives an application through the preset screen projection, and adds the fourth target capability corresponding to the first target application in the first screen projection capability list according to the second capability updating indication to obtain an updated screen projection capability list.

Therefore, after the receiving end calls the screen projection control capability indicated by the second identification information through the first target application, the receiving end can also judge whether the content to be screen projected is the content of the second preset type through the first target application, and when the content to be screen projected is the content of the second preset type, add a fourth target capability in the screen projection control capability supported by the first target application, and instruct the preset screen projection application to add the fourth target capability corresponding to the first target application in the first screen projection capability list by the first target application.

Here, the second preset type of content to be projected supports the fourth target capability, and the fourth target capability may be used in the screen projecting process of the second preset type of content to be projected, so that if the first preset type of content to be projected is projected through the first target application, the fourth target capability may be added to the screen projecting control capability supported by the first target application (that is, the fourth target capability is added to the screen projecting control capability supported by the first target application stored inside the first target application), and the fourth target capability corresponding to the first target application may be added to the first screen projecting capability list, so as to achieve an effect that the fourth target capability of the first target application may be used in the screen projecting process of the second preset type of content to be projected.

For example, the receiving end is a screen-casting television, the sending end is a mobile phone, the application a is a preset screen-casting receiving application, and the application B is a first target application, after the application B calls the screen-casting control capability indicated by the second identification information, it can be determined whether the content to be screen-cast is on-demand content, and in the case that the content to be screen-cast is on-demand content, the application B can increase the jump capability in the screen-casting control capability supported by the application B stored inside, and notify the application a to increase the jump capability of the application B in the first screen-casting capability list, so that the effect of using the jump function of the application B in the screen-casting process of the screen-casting television on-demand content is achieved.

As can be seen from the above steps D-1 to D-4, when the first target application to be called by the receiving end is not the preset screen projection receiving application, the first screen projection capability list may also be updated correspondingly according to the type of the content to be screen projected. The preset screen projection receiving application can communicate with the sending end, so that a first screen projection capability list is provided for the sending end, namely the first screen projection capability list can be managed by the preset screen projection receiving application, and therefore the first screen projection capability list can be correspondingly updated by the preset screen projection receiving application according to the type of the content to be projected, and the latest first screen projection capability list can be provided for the sending end more timely.

In an alternative embodiment of the invention, the method further comprises the following step E-1 and/or step E-2:

step E-1: under the condition that the number of screen projection receiving applications installed on the receiving end is increased, the receiving end updates the first screen projection capability list according to the newly installed screen projection receiving applications to obtain an updated screen projection capability list;

step E-2: and under the condition that the number of screen projection receiving applications installed on the receiving terminal is reduced, deleting the screen projection control capability supported by the unloaded screen projection receiving applications in the first screen projection capability list by the receiving terminal to obtain an updated screen projection capability list.

The receiving terminal can monitor the system information of the receiving terminal through the preset screen projection receiving application and judge whether the number of the screen projection receiving applications installed on the receiving terminal changes or not according to the system information; it should be noted that the system message may include an install or uninstall message of the screen projection receiving application.

In addition, when the preset screen-casting receiving application monitors that the system message is a message that the screen-casting receiving application is installed, the number of screen-casting receiving applications installed on the receiving end is increased; and in the case that the monitored system message is a message that the screen-casting receiving application is uninstalled, the screen-casting receiving application installed on the receiving terminal is reduced.

Therefore, when the number of the screen projection receiving applications installed on the receiving terminal changes, the fact that a new screen projection receiving application is installed is indicated, or the installed screen projection receiving applications are uninstalled is indicated, the screen projection control capacity corresponding to each screen projection receiving application included in the first screen projection capacity list can be increased or reduced, the situation that the number of the installed screen projection receiving applications changes is monitored in real time, the screen projection control capacity included in the first screen projection capacity list can be updated in time, and therefore the first screen projection capacity list is matched with the situation of the screen projection receiving applications actually installed on the receiving terminal.

In an optional embodiment of the present invention, in the step E-1, "the receiving end updates the first screen projection capability list according to the newly installed screen projection receiving application to obtain an updated screen projection capability list", includes the following steps F-1 to F-3:

step F-1: the receiving end sends a second capability list request to the newly installed screen projection receiving application through a preset screen projection receiving application;

step F-2: the receiving end receives a second screen projection capability list sent by the newly installed screen projection receiving application through the preset screen projection receiving application, wherein the second screen projection capability list comprises screen projection control capability supported by the newly installed screen projection receiving application;

step F-3: and the receiving terminal adds the screen projection control capability included in the second screen projection capability list to the first screen projection capability list to obtain an updated screen projection capability list.

Therefore, when a new screen projection receiving application is installed on the receiving end, the screen projection control capability supported by the newly installed screen projection receiving application can be added into the first screen projection capability list, so that the first screen projection capability list is matched with the condition of the screen projection receiving application actually installed on the receiving end, and the screen projection process can be smoothly carried out.

For example, a screen projection receiving application is preset as application a; the newly installed screen projection receiving application is application B, and the screen projection control capability supported by application B comprises a capability a and a capability B, so that the receiving end can send a second capability list request to application B through application A to trigger application B to send the capability a and the capability B to application A, and thus the receiving end can add the capability a and the capability B to the first screen projection capability list through application A to obtain an updated screen projection capability list.

In an optional embodiment of the present invention, after obtaining the updated list of screen projection capabilities (i.e. the aforementioned steps C-1, C-2, D-4, E-1, E-2, F-3), the method further comprises the following steps G-1 to G-3:

step G-1: the receiving terminal sends first prompt information to the sending terminal, wherein the first prompt information is used for prompting that a screen throwing capability list of the receiving terminal is updated;

step G-2: the sending end sends a third capability list request to the receiving end;

step G-3: and the sending end receives the updated screen throwing capability list sent by the receiving end.

The first prompt message can be a short message prompt message; for example, if the receiving end is a screen-casting television, the sending end is a mobile phone, and the preset screen-casting receiving application is application A, after the screen-casting television updates the first screen-casting capability list through application A, a short message prompt can be sent to the mobile phone to prompt that the screen-casting capability list in the television is updated; and triggering the mobile phone to send a third capability list request to the screen projection television, so that the screen projection television sends the updated screen projection capability list to the mobile phone.

Therefore, after the receiving end updates the first screen projection capability list, the prompt message can be sent to the sending end in real time, so that the receiving end synchronously updates the first screen projection capability list, and when a user projects a screen, the problem that subsequent screen projection fails due to the fact that the first screen projection capability list stored in the sending end is inconsistent with the first screen projection capability list stored in the receiving end is avoided.
