It should be noted that the foregoing embodiment is only one possible structure of the display device provided in the embodiment of the present application, and does not constitute a limitation on the display device provided in the embodiment of the present application. Any display device capable of implementing the dual screen display method shown in fig. 10 described below is within the scope of the display device provided by the embodiments of the present application.

The following explains the dual-screen display method provided in the embodiments of the present application in detail.

Fig. 10 is a flowchart illustrating a dual screen display method applied to a display device according to an exemplary embodiment. The present invention may be applied to a controller included in a display device, where the controller may be the first controller 210 in fig. 5 or the second controller 310 in fig. 5, and this is not limited in this embodiment of the present invention. The following embodiments are explained only taking the display device as an execution subject. Referring to fig. 10, the method may include the following steps:

step 1001: the display device plays the media assets in the first display.

Wherein the display device includes a first display and a second display. Illustratively, the first display is a main display of the display device, and the second display is a sub-display of the display device, wherein a display area of the main display is larger than a display area of the sub-display, and the display device preferentially plays the assets through the main display, and when the main display is occupied, the assets can be played through the sub-display. Illustratively, as shown in fig. 9, the first diagram display area 2011 is the first display, and the second diagram display area 2021 is the second display.

In some embodiments, after the user turns on the display device, the display device may display a first interface in the first display, the first interface including a plurality of asset controls, each asset control corresponding to a asset. If the display device detects that the triggering operation of one of the plurality of asset controls indicates that the user selects the asset, the display device may acquire an asset identifier of the asset, and then send a second request to the server, where the second request includes the asset identifier of the asset, and the second request is used to request the server to feed back asset information of the asset corresponding to the asset identifier. After receiving the second request, the server may obtain the asset information corresponding to the asset identifier based on the asset identifier, where the asset information includes a poster, a play address, and the like of the asset.

Wherein, the asset identifier can be used for uniquely indicating one asset. For example, the asset identification may be the name of the corresponding asset.

As an example, referring to fig. 11, the display device may transmit the second request to the server through the first display, and receive the media asset information fed back by the server through the first display.

Illustratively, referring to fig. 12, after the user turns on the display device, the display device may display a first interface comprising a plurality of asset controls in a first display. At this time, the second display has no content to be displayed, and may display default information, which is a clock in fig. 12.

In some embodiments, the server sends the acquired media information to the display device, and after receiving the media information, the display device may switch from the first interface of the first display to the second interface, display the poster, the brief introduction, and the like of the media information on the second interface, and may further display the selection control and the play control. And if the display equipment receives a playing instruction, the playing instruction is generated by detecting the triggering operation executed by the user on the playing control. After receiving the playing instruction, the display device may send a third request for the media asset to the server, where the third request includes the playing address, and after receiving the third request, the server may obtain the media asset based on the playing address in the third request, and send the obtained media asset to the display device, and after receiving the media asset, the display device may play the media asset in the first display.

As an example, referring to fig. 11, the display device may transmit the third request to the server through the first display, receive the asset fed back by the server through the first display, and then play the asset in the first display.

Illustratively, referring to FIG. 13, the display device displays a second interface that includes a poster, a vignette, an album control, and a play control for the asset. At this point, the second display may still display default information.

In order to promote the consumption of the user, popularization information can be pushed to the user in the process of playing the media assets.

Further, the server can determine a reference time point in the stored media assets and promotion information identification needing to be pushed. As an example, for any stored media asset, the server may perform image recognition on a video frame of the any media asset, determine a time point at which promotion information needs to be pushed in the any media asset, and determine a promotion information identifier that needs to be pushed based on the image recognition. The server can also correspondingly store the media assets, the reference time points determined in the media assets and the popularization information identifications, and one reference time point corresponds to one popularization information identification.

Further, the server may set a reference mark at a reference time point, and correspondingly store the media asset, the reference mark set in the media asset, and the promotion information identifier, where one reference mark corresponds to one promotion information identifier.

In this case, after receiving the third request, the server may obtain the media asset, the reference time point and the promotion information identifier stored corresponding to the media asset based on the play address in the third request, or may obtain the media asset, the reference mark and the promotion information identifier stored corresponding to the media asset based on the play address in the third request.

For example, referring to fig. 11, the display device may receive, through the first display, the asset fed back by the server, and the reference time point and the promotion information identifier stored corresponding to the asset, and then play the asset in the first display. Or receiving the media assets fed back by the server, and the reference marks and the promotion information marks which are stored corresponding to the media assets, and then playing the media assets in the first display.

Step 1002: in the process of playing the media assets, responding to the fact that the current playing state of the media assets meets the promotion information pushing condition, and sending a first request to a server, wherein the first request is used for requesting to acquire promotion information associated with the media assets.

Wherein, the promotion information can be advertisement. The promotional information may include product links, posters, etc.

And the current playing state of the media assets meets the promotion information pushing condition, so that the promotion information can be pushed to the user currently.

That is to say, if it is determined that the current playing state of the media asset meets the promotion information pushing condition in the process of playing the media asset, it indicates that promotion information pushing can be performed, and a first request can be sent to the server, so that the server can feed back the promotion information associated with the media asset.

In some embodiments, referring to fig. 11, in the process of playing the media asset, if it is determined that the current playing state of the media asset meets the promotion information pushing condition through the first display, the first display may send a promotion information acquisition instruction to the second display. After receiving the promotion information acquisition instruction, the second display may send a first request to the server, where the first request is used to request to acquire promotion information associated with the media assets.

In fig. 11, the first display and the second display each include a chip having an information processing function.

In implementation, in the process of playing the media assets, in response to that the current playing state of the media assets meets the promotion information pushing condition, the sending of the first request to the server includes the following three implementation manners:

the first implementation mode comprises the following steps: in the process of playing the media assets, in response to detecting a reference mark, determining that the current playing state of the media assets meets the promotion information pushing condition, wherein the reference mark is used for showing that promotion information pushing is carried out at the time point marked by the reference mark, and the reference mark is calibrated by the server based on the media assets. And acquiring a promotion information identifier corresponding to the reference mark, and sending a first request to the server, wherein the first request comprises the promotion information identifier.

Wherein, the promotion information identifier can be used for indicating one promotion information. For example, the promotion information identifier may be a name and a brand of a product corresponding to the promotion information.

That is to say, in the process that the display device plays the media assets through the first display, if the reference mark is detected, it is indicated that the promotion information pushing can be performed, that is, the current playing state of the media assets is considered to meet the promotion information pushing condition, then the promotion information identifier corresponding to the reference mark can be acquired, and a first request for acquiring the promotion information is sent to the server, where the first request includes the promotion information identifier.

As an example, in this implementation manner, when acquiring a media asset, the display device acquires a reference mark and a promotion information identifier that are stored corresponding to the media asset at the same time, and there is a one-to-one correspondence between the reference mark and the promotion information identifier. In the process of playing the media assets, the display device can monitor the playing of the media assets in real time, if the fact that the video frames played at a certain moment correspond to the reference marks indicates that promotion information needs to be pushed, and it can be determined that the current playing state of the media assets meets promotion information pushing conditions. And then, according to the corresponding relation between the reference mark and the promotion information mark, determining the promotion information mark corresponding to the reference mark, and then sending a first request for obtaining the promotion information to the server, wherein the first request carries the determined promotion information mark, so that the server can obtain the promotion information based on the promotion information mark.

The second implementation mode comprises the following steps: and in the process of playing the media assets, detecting the playing progress of the media assets. And responding to the situation that the playing progress of the media assets is located at a reference time point, determining that the current playing state of the media assets meets the promotion information pushing condition, wherein the reference time point is a time point for pushing promotion information in the media asset playing process. And acquiring the promotion information identifier corresponding to the reference time point. And sending a first request to the server, wherein the first request comprises the promotion information identification.

That is to say, in the process that the display device plays the media assets through the first display, the display device may detect the play progress of the media assets in real time, and if it is determined that the media assets are played to the reference time point based on the play progress of the media assets, it is indicated that the media assets are played to the time point at which the promotion information is to be promoted, that is, the current play state of the media assets is considered to meet the promotion information promotion condition. Then, a promotion information identifier corresponding to the reference time point may be obtained, and a first request for obtaining the promotion information is sent to the server, where the first request includes the promotion information identifier.

As an example, in this implementation manner, when acquiring a media asset, the display device acquires a reference time point and a promotion information identifier that are stored in correspondence with the media asset, and there is a one-to-one correspondence between the reference time point and the promotion information identifier. In the process of playing the media assets, the display device can detect the playing progress of the media assets in real time, and if the playing progress of the media assets is detected to be at the reference time point, namely the media assets are played to the time point needing to push the promotion information, the current playing state of the media assets can be considered to meet the promotion information pushing condition. And then, according to the corresponding relation between the reference time point and the promotion information identifier, determining the promotion information identifier corresponding to the reference time point, and then sending a first request for obtaining the promotion information to the server, wherein the first request carries the determined promotion information identifier, so that the server can obtain the promotion information based on the promotion information identifier.

The third implementation mode comprises the following steps: and in the process of playing the media assets, responding to the screenshot operation, and determining that the current playing state of the media assets meets the promotion information pushing condition. And acquiring the intercepted reference image, wherein the reference image comprises an image of a product corresponding to the promotion information. A first request is sent to a server, the first request including a reference image.

That is to say, in the process that the display device plays the media assets through the first display, if the screenshot operation is detected, it is indicated that the user may want to know a certain product, the promotion information corresponding to the product may be pushed to the user, that is, the current playing state of the media assets may be considered to meet the promotion information pushing condition. And then, a reference image intercepted by the screenshot operation can be acquired, a first request comprising the reference image is sent to the server, and the server can acquire the promotion information based on the reference image because the reference image comprises the image of the product corresponding to the promotion information.

In this implementation, the server does not mark the reference time point, which may be because promotion information pushing is too frequent, and it is desired to reduce promotion information pushing, but the user is interested in the product, so the user may control the display device to perform screenshot operation through the control device or the gesture. If the display device detects the screenshot operation, it indicates that the user may want to know about the product, and therefore the current playing state of the media assets can be considered to meet the promotion information pushing condition. The intercepted reference image can be acquired, and a first request can be sent to the server, and the reference image is included in the first request because the reference image includes an image of a product which the user wants to know, so that the server can acquire popularization information based on the reference image.

Step 1003: and receiving the promotion information sent by the server based on the first request.

In implementation, the server may obtain the promotion information based on the first request, and then send the obtained promotion information to the display device, and the display device may receive the promotion information sent by the server.

For example, referring to fig. 11, after receiving the first request, the server may feed back the promotion information to the second display based on the first request.

In implementation, the server may store a plurality of pieces of promotion information and a plurality of sets of correspondences, where each set of correspondence is a correspondence between each piece of promotion information and a corresponding promotion information identifier. Or, a plurality of promotion information may be stored in the server, and each promotion information is stored in correspondence with a corresponding promotion information identifier.

As an example, if the first request includes a promotion information identifier, the server may determine promotion information corresponding to the promotion information identifier from multiple sets of corresponding relationships stored in the server directly based on the promotion information identifier, and obtain the promotion information. Or, the promotion information stored corresponding to the promotion information identifier may be directly determined as promotion information to be acquired, and the promotion information may be acquired.

As another example, if the first request includes a reference image, the server may perform image recognition on the reference image, determine a name and a brand of a product in the reference image, determine the name and the brand of the product as a promotion information identifier, and then obtain the promotion information in the manner described in the previous example based on the promotion information identifier.

Step 1004: the display device plays the promotional information in the second display.

In implementation, referring to fig. 11, after the second display receives the promotion information sent by the server, the promotion information may be played in the second display.

Illustratively, referring to fig. 14, the media asset is played in the first display and the promotional information is played in the second display.

It should be noted that, in the process of playing the promotion information in the second display, the first display is still playing the media asset. That is, the broadcast of the promotion information and the broadcast of the media assets are not influenced with each other, so that the promotion information can be pushed to the user, the media assets watched by the user can not be influenced, and the use experience of the user is improved.

Further, if the user is interested in the promotion information played by the second display and wants to know or purchase the product promoted by the promotion information in detail, the promotion information can be played in the first display due to the fact that the area of the first display is larger than that of the second display, and the promotion information is convenient to use for operation.

In implementation, in response to detecting the switching playing instruction, the media assets are played in the second display, and the promotion information is played in the first display.

As an example, the switch play instruction may be generated based on a detected switching operation. The switching operation may be performed by a user through the control device.

That is, if the switching playing instruction is detected, it indicates that the promotion information needs to be played in the display with a larger area, that is, the promotion information can be played in the first display, and the media asset can be played in the second display.

In one possible implementation manner, in response to a purchase operation process of a product corresponding to the promotion information, if the current playing state of the media asset meets the promotion information pushing condition, the next promotion information associated with the media asset is obtained. And controlling the first display to play the next promotion information in the reference area.

The reference area is any one of the top, bottom, left side or right side of the first display, and usually occupies a small part of the first display.

That is, in this implementation, if the next promotion information needs to be pushed in the process of executing the purchase operation in the first display, the next promotion information associated with the media asset may be acquired, and then the next promotion information is played in the reference area of the first display.

As an example, the first display may be controlled by the controller to play the next promotion information within the reference area.

So, the in-process of the product that the purchase popularization information corresponds can not influence the propelling movement of next popularization information, can reach better propelling movement effect.

It should be noted that, the process of acquiring the next promotion information associated with the media asset when the current playing state of the media asset meets the promotion information pushing condition is the same as the process of acquiring the promotion information when the current playing state of the media asset meets the promotion information pushing condition in the foregoing embodiment, which may be specifically referred to the related description of the foregoing embodiment, and this embodiment is not described again here.

In another possible implementation manner, in response to a purchase operation process of a product corresponding to the promotion information, if the current playing state of the media asset meets the promotion information pushing condition, the next promotion information associated with the media asset is obtained. And in response to the end of the purchase operation and the non-playing end of the media assets, stopping playing the promotion information in the first display, and stopping playing the media assets in the second display. And playing the media assets in the first display, and playing the next promotion information in the second display.

That is to say, in this implementation, if the next promotion information needs to be pushed in the process of executing the purchase operation in the first display, the next promotion information associated with the media asset may be acquired, but at this time, the next promotion information is not played, but the next promotion information is stored first. And under the condition that the purchase is finished and the media asset is not played, executing a play switching instruction, stopping playing the promotion information in the first display, stopping playing the media asset in the second display, and exchanging the contents played by the first display and the second display, namely continuously playing the media asset in the first display and playing the next promotion information in the second display.

As an example, the controller may control the first display to stop playing the promotion information to continue playing the media asset, and control the second display to stop playing the media asset to play the next promotion information.

Therefore, in the process of purchasing a product corresponding to the promotion information by the user, the next promotion information is not played temporarily, any influence on the purchasing operation is avoided, and the use experience of the user can be improved. And after the purchase is finished, the next promotion information is played, so that the user can better browse the experience of the next promotion information.

In another possible implementation manner, in response to the purchase operation process of the product corresponding to the promotion information, the second display is controlled to stop playing the media assets. And in response to the end of the purchase operation and the non-playing end of the media assets, stopping playing the promotion information in the first display, and playing the media assets in the first display.

That is to say, in this implementation manner, in the process of executing the purchasing operation in the first display, the playing of the media assets in the first display may be stopped, and after the purchasing is finished and the playing of the media assets is not finished, the contents played by the first display and the second display are exchanged, that is, the playing of the promotion information is stopped in the first display, and the playing of the media assets is continued in the first display.

Further, the media assets can be stopped playing in the second display, and the promotion information or the default information can be played in the first display.

As an example, the controller may control the first display to stop playing the promotion information to continue playing the media asset, and control the second display to stop playing the media asset to continue playing the promotion information or the default information.

Therefore, the media assets are paused in the process of purchasing products by the user, the user can enjoy better shopping experience, the user can not be influenced to watch the media assets, the user can not miss the next promotion information, and better use experience can be brought to the user.

Further, the playing progress of the media assets is detected. And in response to the fact that the playing of the media assets is finished based on the playing progress of the media assets, stopping playing the promotion information in the second display.

As an example, in the process of playing the media assets, the playing progress of the media assets may also be detected, if the playing progress of the media assets is the end time point, it may be determined that the playing of the media assets is ended, that is, the playing of the media assets is considered to be ended, and then the controller may control the second display to stop playing the promotion information.

In the embodiment of the application, the display device includes a first display and a second display, the media asset can be played in the first display, and in the process of playing the media asset, if the display device determines that the current playing state of the media asset meets the promotion information pushing condition, it is indicated that the promotion information can be pushed, and then the first request can be sent to the server. And receiving promotion information related to the media assets, which is acquired by the server based on the first request, and then playing the promotion information in the second display. Therefore, when promotion information pushing is needed, the promotion information can be played in the second display, the first display cannot be occupied, the media assets can still be played normally by the first display, the media assets do not need to be played continuously after the promotion information is played, the playing efficiency of the media assets is improved, a user does not need to wait, and the use experience of the user is improved.
