[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] The present invention provides a screen mirroring method, which is applied to a screen mirroring display end, such as Figure 1 As shown, this method includes:

[0052] Step 101: In response to a screen mirroring request sent by the screen mirroring transmitting end through a first application, send the screen mirroring information address to the screen mirroring transmitting end, so that the screen mirroring transmitting end can obtain the screen mirroring display end information pointed to by the screen mirroring information address; wherein, the screen mirroring display end information at least includes information reflecting the applications possessed by the screen mirroring display end.

[0053] When screen mirroring, the screen mirroring transmitting end sends a screen mirroring request, and this screen mirroring request is sent through the first application possessed by the screen mirroring transmitting end. If the screen mirroring display end has this first application, it will respond to this screen mirroring request. If the screen mirroring display end does not have this first application, it will not respond to this screen mirroring request. Optionally, this first application can be an application of the video type. The screen mirroring display end can include but is not limited to a TV, a display screen, a set-top box, and a projector. The screen mirroring transmitting end can include but is not limited to a computer, a tablet computer, and a mobile phone. The screen mirroring display end and the screen mirroring transmitting end can interact based on the DLNA protocol.

[0054] After the screen mirroring display end responds to the screen mirroring request sent by the screen mirroring transmitting end, the screen mirroring display end sends the screen mirroring information address to the screen mirroring transmitting end. The screen mirroring display end information pointed to by this screen mirroring information address has the application information possessed by the screen mirroring display end, and through this application information, it can be reflected whether the screen mirroring display end has the first application.

[0055] Step 102: Receive the application program identifier sent by the screen mirroring transmitting end when it is confirmed that the applications possessed by the screen mirroring display end include the first application, and judge whether the application program identifier is consistent with the program identifier of the first application. If they are consistent, obtain multiple video playback addresses provided by the first application at least based on the video identifier sent by the screen mirroring transmitting end; wherein, the video identifier is the identifier of the video in the first application.

[0056] The screen mirroring transmitting end uses the obtained screen mirroring display end information to confirm whether the screen mirroring display end has a first application. If the screen mirroring transmitting end determines that the screen mirroring display end has the first application, it sends the application identifier corresponding to the first application. The screen mirroring display end verifies the application identifier to verify the identity of the screen mirroring transmitting end, and processes the video identifier of the video in the first application sent by the screen mirroring transmitting end when the verification is passed. Specifically, multiple video playback addresses provided by the first application can be obtained based on the video identifier. Among them, the video content corresponding to the multiple video playback addresses is the same video content with different resolutions. Optionally, the video identifier can be a video ID.

[0057] As an optional implementation manner, obtaining multiple video playback addresses provided by the first application based on the video identifier sent by the screen mirroring transmitting end includes: obtaining the video playback addresses corresponding to the videos with the video identifier and different resolutions based on the video identifier sent by the screen mirroring transmitting end.

[0058] For videos of the same video content, the video identifier can be the same, and the video resolution can be different. Therefore, the video playback addresses corresponding to videos with different resolutions are different. When the first application can provide the same video content with multiple video resolutions, there will be multiple video playback addresses.

[0059] As another optional implementation manner, obtaining multiple video playback addresses provided by the first application based on the video identifier sent by the screen mirroring transmitting end includes: obtaining the video playback addresses corresponding to at least one video with the video identifier and the video playback addresses corresponding to different videos with the same video set identifier based on the video identifier and the video set identifier sent by the screen mirroring transmitting end; where the video set includes videos with the video identifier. Optionally, the video set identifier can be a media asset ID.

[0060] For a video set, the video playback addresses corresponding to multiple videos in the same video set are different, and the video content corresponding to different video playback addresses is also different, but the video set identifiers of multiple videos in the same video set are the same. For example, if the video set is a TV drama series, a TV drama includes dozens of episodes of films, the video playback addresses corresponding to different episodes of films are different, and different episodes of films have the same video set identifier. Since one video identifier can correspond to at least one video playback address, one video set identifier can correspond to multiple different videos, and multiple different videos will have multiple video playback addresses, multiple video playback addresses provided by the first application can be obtained based on the video identifier and the video set identifier sent by the screen mirroring transmitting end.

[0061] As another optional implementation, based on the video identifier sent by the screen mirroring transmitter, obtain multiple video playback addresses provided by the first application, including: based on the video identifier and the clarity list sent by the screen mirroring transmitter, obtain the video playback address corresponding to the video with the video identifier and matching the clarity in the clarity list.

[0062] There can be multiple different clarities in the clarity list. Use the video identifier to find multiple videos with different clarities in the first application, and then filter the clarities of the found multiple videos through the clarity list to obtain the video playback address corresponding to the video that matches the clarity in the clarity list.

[0063] Step 103: Select a video playback address according to the video playback requirement and play the video content pointed to by the selected video playback address.

[0064] As an optional implementation, selecting a video playback address according to the video playback requirement includes: selecting the video playback address corresponding to the video with the highest clarity among multiple video playback addresses. By selecting the video playback address corresponding to the video with the highest clarity, the user experience of watching videos can be improved.

[0065] As another optional implementation, selecting a video playback address according to the video playback requirement includes: selecting the video playback address corresponding to the video other than the current video in the video set; the video identifier of the current video is the video identifier sent by the screen mirroring transmitter.

[0066] By selecting the video playback address corresponding to the video other than the current video, the switching of video episodes can be realized. Instead of being limited to the single video address provided by the video transmitter for video playback, the video playback address is selected and played using the video resources in the first application on the screen mirroring display terminal. Thus, on the screen mirroring display terminal, the video source, episode number, and clarity can be switched, the video presentation form is diversified, and the user experience is improved.

[0067] In an optional embodiment, after determining that the application identifier is consistent with the program identifier of the first application, the screen mirroring method provided by the present invention further includes: sending the public key to the screen mirroring transmitter so that the screen mirroring transmitter encrypts the user permission information based on the public key to obtain the encrypted user permission information; decrypting the encrypted user permission information sent by the screen mirroring transmitter using the private key to obtain the user permission information; screening the video play address corresponding to the video identifier provided by the first application based on the user permission information to obtain the screened video play address, and the screened video play address is the video play address that matches the user permission information. Optionally, the user permission information may include user video play entitlement information, user identifier, etc. Through the user video play entitlement information in the user permission information, it can be determined whether the user is an ordinary user or a VIP user. The clarity of the video provided for VIP users is higher than that of the video provided for ordinary users. Optionally, the user identifier may be the user id.

[0068] Optionally, select a video play address according to the video play requirements and play the video content pointed to by the selected video play address, including: according to the video play requirements, select the video content pointed to by a screened video play address for playing. The video play requirements may be video play requirements related to video clarity, video source, number of video episodes, etc. The video play addresses corresponding to different video play requirements are different. For different user video play entitlement information, the selectable video play addresses are also different.

[0069] As an optional implementation manner, the screen mirroring method of the present invention further includes:

[0070] If the application program on the screen mirroring display end does not include the first application program, or the application identifier sent by the screen mirroring transmitter is inconsistent with the program identifier of the first application program, then play the video content pointed to by the video play address sent by the screen mirroring transmitter.

[0071] When the application program on the screen mirroring display end does not include the first application program, the screen mirroring display end cannot provide a video play address. At this time, it is necessary to receive the video play address sent by the screen mirroring transmitter to play the video content pointed to by the address.

[0072] When the screen mirroring display end fails to verify the application identifier sent by the screen mirroring transmitter, since the program identifiers are inconsistent, it may cause the screen mirroring display end to be unable to find the corresponding video play address through the video identifier sent by the screen mirroring transmitter. At this time, it is also necessary to receive the video play address sent by the screen mirroring transmitter to play the video content pointed to by the address.

[0073] Of course, in addition to playing the video content pointed to by the video playback address sent by the screen mirroring transmitting end for handling the above two situations, it may also be impossible to screen the video playback address corresponding to the video identifier provided by the first application based on the user permission information, or receive the video playback address sent by the screen mirroring display end when the screen mirroring display end does not have a video playback address meeting the clarity requirements, so that the screen mirroring display end can play the video content pointed to by the received video playback address using the received video playback address.

[0074] As an optional implementation manner, the screen mirroring method of the present invention further includes:

[0075] Based on the user video playback history sent by the screen mirroring transmitting end, obtain the video identifier of the video related to the user video playback history in the first application, and display the video information corresponding to the obtained video identifier on the screen mirroring display end and / or the screen mirroring transmitting end.

[0076] The user video playback history can reflect the user's media preference. Through the user video playback history sent by the screen mirroring transmitting end, the screen mirroring display end can find the video identifier of the video related to the user video playback history in the first application, so as to provide the user with video information that meets the user's media preference. In addition, in order to ensure the secure transmission of the user video playback history, the user video playback history can be encrypted using the public key sent by the screen mirroring display end before sending the history.

[0077] The present invention also provides a screen mirroring system, which is applied to the screen mirroring display end, as Figure 2 shown. The system includes:

[0078] A screen mirroring response module 201, configured to respond to a screen mirroring request sent by the screen mirroring transmitting end through the first application, and send the screen mirroring information address to the screen mirroring transmitting end, so that the screen mirroring transmitting end can obtain the screen mirroring display end information pointed to by the screen mirroring information address; wherein, the screen mirroring display end information at least includes information reflecting the application programs possessed by the screen mirroring display end.

[0079] A video playback address obtaining module 202, configured to receive the application program identifier sent by the screen mirroring transmitting end when it is confirmed that the application programs possessed by the screen mirroring display end include the first application, determine whether the application program identifier is consistent with the program identifier of the first application, and if they are consistent, obtain multiple video playback addresses provided by the first application at least based on the video identifier sent by the screen mirroring transmitting end; wherein, the video identifier is the identifier of the video in the first application.

[0080] A video playback module 203, configured to select a video playback address according to the video playback requirements and play the video content pointed to by the selected video playback address.

[0081] Among them, the video playback address acquisition module 202 is specifically configured to acquire multiple video playback addresses by any one of Method 1 to Method 3:

[0082] Method 1: Based on the video identifier sent by the screen mirroring transmitter, acquire the video playback addresses corresponding to the videos with the video identifier and different resolutions.

[0083] Method 2: Based on the video identifier and the video set identifier sent by the screen mirroring transmitter, acquire the video playback addresses corresponding to at least one video with the video identifier, and the video playback addresses corresponding to different videos with the same video set identifier; wherein, the video set includes videos with the video identifier.

[0084] Method 3: Based on the video identifier and the resolution list sent by the screen mirroring transmitter, acquire the video playback addresses corresponding to the videos with the video identifier and matching the resolutions in the resolution list.

[0085] The video playback module 203 is specifically configured to select the video playback address corresponding to the video with the video identifier and the highest resolution from multiple video playback addresses; or, select the video playback address corresponding to the video other than the current video in the video set from multiple video playback addresses; the video identifier of the current video is the video identifier sent by the screen mirroring transmitter.

[0086] The screen mirroring system of the present invention further includes:

[0087] An address screening module, configured to send the public key to the screen mirroring transmitter so that the screen mirroring transmitter encrypts the user permission information based on the public key to obtain the encrypted user permission information; decrypt the encrypted user permission information sent by the screen mirroring transmitter using the private key to obtain the user permission information; based on the user permission information, screen the video playback addresses corresponding to the video identifier provided by the first application program to obtain the screened video playback addresses, and the screened video playback addresses are the video playback addresses matching the user permission information.

[0088] The video playback module 203 is further configured to select the video content pointed to by one of the screened video playback addresses for playback according to the video playback requirements.

[0089] The screen mirroring system of the present invention further includes:

[0090] An address receiving module, configured to play the video content pointed to by the video playback address sent by the screen mirroring transmitter if the application program on the screen mirroring display end does not include the first application program, or the application program identifier sent by the screen mirroring transmitter is inconsistent with the program identifier of the first application program.

[0091] A video identifier acquisition module, configured to acquire video identifiers of videos related to the user's video playback history in a first application based on the user's video playback history sent by the screen mirroring transmitting end, and display video information corresponding to the acquired video identifiers on the screen mirroring display end and / or the screen mirroring transmitting end.

[0092] The present invention also provides a screen mirroring method, which is applied to the screen mirroring transmitting end. As Figure 3 shown, the screen mirroring method includes:

[0093] Step 301: Send a screen mirroring request through the first application, receive the screen mirroring information address sent by the screen mirroring display end in response to the screen mirroring request, and acquire the screen mirroring display end information pointed to by the screen mirroring information address; wherein, the screen mirroring display end information at least includes information reflecting the applications available on the screen mirroring display end.

[0094] If the screen mirroring transmitting end has the first application, it can send a screen mirroring request through the first application. If the screen mirroring display end also has the first application, it will respond to the screen mirroring request, and the screen mirroring display end will send the screen mirroring information address. After receiving the screen mirroring information address, the screen mirroring transmitting end confirms that the screen mirroring display end has the first application, so as to execute step 302.

[0095] Step 302: Determine whether the screen mirroring display end has the first application based on the screen mirroring display information. If the screen mirroring display end has the first application, send the video identifier and the application identifier of the first application, so that the screen mirroring display end, when confirming that the application identifier is consistent with the program identifier of the first application, selects the video content pointed to by the video playback address that meets the video playback requirements from the multiple video playback addresses provided by the first application for playback; wherein, the video identifier is the identifier of the video in the first application.

[0096] If the screen mirroring display end has the first application, the screen mirroring transmitting end will send the video identifier of the video to be screen mirrored, and at the same time send the first program identifier for the screen mirroring display end to verify. When the screen mirroring display end verifies that the program identifiers are consistent, it can obtain the multiple video playback addresses provided by the first application using the video identifier sent by the screen mirroring transmitting end. The screen mirroring display end selects a video playback address according to the video playback requirements and plays the video content pointed to by the selected video playback address.

[0097] The screen mirroring display end can obtain the multiple video playback addresses provided by the first application based on the video identifier sent by the screen mirroring transmitting end. Specifically, there are three ways to obtain the multiple video playback addresses as follows:

[0098] Way 1: Based on the video identifier sent by the screen mirroring transmitting end, obtain the video playback addresses corresponding to the videos with the video identifier and different resolutions.

[0099] Method 2: Based on the video identifier and video set identifier sent by the screen mirroring transmitter, obtain the video playback addresses corresponding to at least one video with the video identifier, and the video playback addresses corresponding to different videos with the same video set identifier; wherein, the video set includes videos with video identifiers.

[0100] Method 3: Based on the video identifier and the clarity list sent by the screen mirroring transmitter, obtain the video playback address corresponding to the video with the video identifier and matching the clarity in the clarity list.

[0101] When the screen mirroring display end selects a video playback address that meets the video playback requirements, it can select the video playback address corresponding to the video with the highest clarity among multiple video playback addresses; or, select the video playback address corresponding to the video other than the current video in the video set from multiple video playback addresses; the video identifier of the current video is the video identifier sent by the screen mirroring transmitter.

[0102] As an optional implementation manner, the screen mirroring method of the present invention further includes at least one of the following manners:

[0103] Method 1: Receive the public key sent by the screen mirroring display end, encrypt the user permission information based on the public key to obtain the encrypted user permission information, and send the encrypted user permission information to the screen mirroring display end, so that after the screen mirroring display end decrypts the encrypted user permission information with the private key to obtain the user permission information, it filters the multiple video playback addresses corresponding to the video identifier provided by the first application program based on the user permission information, and plays the video content pointed to by the filtered video playback address that meets the video playback requirements.

[0104] After the screen mirroring display end determines that the application program identifier sent by the screen mirroring transmitter is the same as the first application program identifier, the screen mirroring display end sends the public key to the screen mirroring transmitter, and the screen mirroring transmitter can encrypt the user permission information based on the public key. The user permission information may include, but is not limited to, user video playback right information, user identifier, etc. The screen mirroring display end can obtain the filtered video playback address through the user permission information to play the video content pointed to by the address.

[0105] Method 2: Send the video playback address to the screen mirroring display end, so that when the screen mirroring display end does not have the first application program or the application program identifier is inconsistent with the program identifier of the first application program, the screen mirroring display end plays the video content pointed to by the received video playback address.

[0106] The screen mirroring transmitting end can send a video playback address to the screen mirroring display end. When the screen mirroring display end cannot obtain the video playback address through the first application or cannot obtain the video playback address through the video identifier, the video content is played using the video playback address sent by the screen mirroring transmitting end.

[0107] Method 3: Send the user's video playback history to the screen mirroring display end, so that the screen mirroring display end can obtain the video identifier of the video related to the user's video playback history in the first application, and display the video information corresponding to the obtained video identifier on the screen mirroring display end.

[0108] The screen mirroring transmitting end can send the user's video playback history to the screen mirroring display end. The screen mirroring display end can obtain the video identifier of the video related to the video playback history. The video information corresponding to the video identifier can be displayed on the screen mirroring transmitting end and the screen mirroring display end, providing users with diverse video content and enhancing the user experience.

[0109] The present invention also provides a screen mirroring system, which is applied to the screen mirroring transmitting end, as Figure 4 shown. The screen mirroring system includes:

[0110] A screen mirroring request sending module 401, configured to send a screen mirroring request through the first application, receive the screen mirroring information address sent by the screen mirroring display end in response to the screen mirroring request, and obtain the screen mirroring display end information pointed to by the screen mirroring information address; wherein, the screen mirroring display end information at least includes information reflecting the applications possessed by the screen mirroring display end.

[0111] An identifier sending module 402, configured to determine whether the screen mirroring display end has the first application based on the screen mirroring display information.
