The hardware or software architecture in some embodiments may be based on the description in the above embodiments, and in some embodiments may be based on other hardware or software architectures that are similar to the above embodiments, and it is sufficient to implement the technical solution of the present application.
In some embodiments, the display device 200 may be a rotating television, i.e., the display 260 can rotate clockwise or counterclockwise about an axis perpendicular to the plane of the display in a specific plane (a vertical plane or a plane having a predetermined angle (less than 45 °) with respect to a vertical axis), and thus can operate in two rotational states, i.e., a landscape state illustrated in fig. 1, i.e., a state in which the long side of the display is in a horizontal direction, and a portrait state illustrated in fig. 1, i.e., a state in which the short side of the display is in a horizontal direction. The rotating television may be provided with a fixing assembly by which the above-described rotation of the display 260 is achieved. The application mainly solves the technical problem that when the rotary television plays media assets, a user controls the rotary television to rotate, so that the media asset playing effect is poor, and therefore the display device in the following embodiment can be the rotary television.
To describe the solution of the above technical problem in detail, the following respectively describes the display device, some features of the assets displayed on the display device, and the process of the user viewing the assets on the display device.
In some embodiments, the controller 250 rotates the display 260 by a fixed angle, such as 90 degrees, according to the rotation instruction. If the display device is in the landscape screen state, the user may send a rotation instruction to the display device through the smart device 300, the control apparatus 100, or a rotation button on the display device, and the controller 250 rotates the display 260 to the portrait screen state according to the rotation instruction; if the display device is in the vertical screen state, the user may send a rotation instruction to the display device through the smart device 300, the control apparatus 100, or a rotation button on the display device, and the controller 250 rotates the display 260 to the horizontal screen state according to the rotation instruction.
In some embodiments, a rotation status flag of the display 260 is stored in the controller 250 or the memory 260 of the display device, for example, the rotation status flag may have two values, which respectively represent a landscape state and a portrait state, when the rotation status of the display 260 changes, the display direction of the display changes, the controller 250 may monitor the change of the display direction by rewriting an onconfiguration changed method, update the value of the rotation status flag after monitoring the change of the display direction, generate a notification message, and send the notification message to the UI process, so that the UI process updates the display direction of the interface to be consistent with the display direction of the display, where the notification message may include value information of the rotation status flag.
In some embodiments, the marking of the spin state may be made internal to the multimedia application (e.g., a JUUI application), the UI process may be a process within the JUUI application, in some embodiments, the marking of the spin state may be made external to the multimedia application (e.g., a JUUI application), and the UI process may be a process within the JUUI application.
In some embodiments, the value of the rotation status indicator may also change in real time following the rotation angle of the display 260.
In some embodiments, the server of the display device may pull some pieces of asset information of the asset from a server of a platform such as a media provider, for example, a super-cool platform, an arcade platform, and the like, process and store the asset information, so as to realize the storage of the asset, and the display device may display the stored asset, so that a user may view the asset through the display device.
In some embodiments, the asset information may include information such as an asset poster, an asset introduction, an asset tag, an asset type, a play address, and the like of an asset, where the play address is an interface address of a video stream of the asset.
In some embodiments, a screen status identifier may be further set in the play address of the media asset information provided by the server of the media asset provider, where the screen status identifier has two possible values, for example, when the value is lan (horizontal printing format), it indicates that the play address is the play address of the horizontal screen video stream of the media asset, and when the value is por (vertical printing format), it indicates that the play address is the play address of the vertical screen video stream of the media asset. The horizontal screen video stream and the vertical screen stream are video streams with different formats, video frames of the horizontal screen video stream and video frames of the vertical screen video stream have different aspect ratios, the width value of the video frames of the horizontal screen video stream is larger than the height value, and the height value of the video frames of the vertical screen video stream is larger than the width value.
If one media asset has both a horizontal screen video stream suitable for horizontal screen playing and a vertical screen video stream suitable for vertical screen playing, two playing addresses can be provided in the media asset information of the media asset, wherein one playing address is provided with a lan, and the other playing address is provided with a por. If one media asset is only suitable for the horizontal screen video stream and is not suitable for the vertical screen video stream, a playing address can be arranged in the media asset information of the media asset, and a lan is arranged in the playing address, or if no screen state identifier is arranged in the playing address, the playing address is defaulted to be the playing address of the horizontal screen video stream. If one piece of media asset only has a vertical screen video stream and does not have a horizontal screen video stream, a playing address can be arranged in the media asset information of the media asset, and the playing address is provided with a por.
In some embodiments, if one piece of media asset has both a horizontal screen video stream and a vertical screen video stream, there may be only one play address in the media asset information of the media asset, where the play address has a first mapping relationship with the horizontal screen video stream of the media asset and a second mapping relationship with the vertical screen video stream, and a lan may be set in the first mapping relationship and a por may be set in the second mapping relationship.
In some embodiments, if the screen status identifier is not included in the asset information of one asset provided by the server of the asset provider, the server may process and store the asset information when performing asset warehousing on the asset, and the processing of the asset information includes adding the screen status identifier to the asset information alone. In order to determine whether the value of the screen state identifier to be added needs to be set as lan or por, the server can acquire a first frame image frame of the video stream of the media asset from the playing address of the media asset information, and determine whether the video stream of the media asset is a horizontal screen video stream or a vertical screen video stream according to the size ratio, namely the aspect ratio, of the first frame image frame. For example, if the size ratio is 16:9, the video stream of the medium asset is determined to be a horizontal screen video stream, and if the size ratio is 9:16, the video stream of the medium asset is determined to be a vertical screen video stream. And if the video stream is a horizontal screen video stream, setting the value of the screen state identifier to be added as lan, and if the video stream is a vertical screen video stream, setting the value of the screen state identifier to be added as por.

In some embodiments, if the display device only supports one play mode, the play mode interface may not be generated, and the play interface of the target media asset may be directly entered, which may be referred to as a second interface.
In some embodiments, the display device plays the target asset based on MediaPlayer, and if the user clicks the normal mode in fig. 8, a start-up instruction to generate the target asset. The display device responds to the play starting instruction, can determine the target media asset as a MediaPlayer object, and obtains the current rotation state of the display according to the value of the current rotation state identifier. And if the current rotation state is the landscape screen state, acquiring a playing address of the landscape screen video stream from the media asset information corresponding to the recommended bit control, namely, the screen state identifier takes the value of the playing address of lan, then accessing the playing address to acquire the landscape screen video stream, and after the landscape screen video stream is acquired, decoding the landscape screen video stream to play the landscape screen video stream on a display. And if the current rotation state is the vertical screen state, acquiring a playing address of the vertical screen video stream from the media asset information corresponding to the recommended bit control, namely acquiring the playing address with the screen state identifier value of por, then accessing the playing address to acquire the vertical screen video stream, and after the vertical screen video stream is acquired, decoding the vertical screen video stream to play the vertical screen video stream on a display.
In some embodiments, only one play address is in the media asset information of the target media asset selected by the user, the display device may temporarily ignore the current rotation state of the display device, acquire the video stream from the play address first, if the play direction of the video stream is consistent with the current rotation state, the video stream may be directly played, and if the play direction of the video stream is not consistent with the current rotation state, the display may be rotated to be consistent with the play direction of the video stream, and then the video stream is played. The playing direction comprises a horizontal screen direction or a vertical screen direction, the horizontal screen direction can correspond to the horizontal screen state, and the vertical screen direction can correspond to the vertical screen state.
Taking the current rotation state of the display device as the landscape screen state as an example, the interface of the display device for playing the landscape screen video stream can be shown in fig. 9, the video frame of the landscape screen video stream can be displayed in a full screen manner, the landscape screen video stream can be referred to as a first video stream, and the playing address of the first video stream can be referred to as a first playing address.
In some embodiments, when the user views the target asset, the user may want to adjust the rotation state of the display device, for example, the user wants to switch the display device from the landscape screen state to the portrait screen state, at this time, the user may input a rotation instruction to the display, the controller of the display device rotates the display by 90 degrees according to the rotation instruction, and after the rotation is completed, the value of the rotation state identifier may be updated.
It should be noted that the player playing the video stream of the target asset before and after the rotation of the display is the same player, and in some embodiments, the player may be a MediaPlayer.
In some embodiments, after a user inputs a rotation instruction, the display device may receive a notification message that a display direction of the display changes, determine, according to the notification message, whether a media type of a currently playing media belongs to a type suitable for vertical screen playing, such as a fitness type, when a target media is a fitness video, the target media belongs to the fitness type, the display device may call a pause () method of a MediaPlayer object to pause a currently playing first video stream according to the target media being the fitness type, obtain and record a current playing progress by a getCurrentPosition () method of the MediaPlayer object, and continue playing the target media from a time corresponding to the playing progress after the display rotates, thereby avoiding a problem that a picture of the target media is in an inclined state to cause poor viewing experience in a rotation process. If the rotation state identifier has only two values, the display device can update according to the values of the rotation state identifier and judge that the rotation of the display is finished; if the rotation state identifier is updated in real time along with the rotation angle of the display, the rotation of the display can be judged to be finished according to the value within the preset time, such as 1 second.
In some embodiments, after the user inputs the rotation instruction, the display device may also suspend playing the first video stream directly according to the notification message that the display direction of the display changes, without determining whether the type of the currently playing media asset is a type suitable for vertical screen playing.
In some embodiments, after the user inputs the rotation instruction, the display device may also not pause the playing of the first video stream, and after the rotation of the display is completed, pause the playing of the first video stream, record the playing progress, and continue playing the target asset according to the playing progress, thereby avoiding the problem that the rotation time may need to be long, and the user needs to wait for a long time because the playing asset is paused in the rotation process.
In some embodiments, after the user inputs the rotation instruction, the display device needs to obtain the video stream corresponding to the other display state according to the second playing address.
In some embodiments, to ensure that the display device can continue playing the target media asset in time after the display device is rotated, the display device may determine, after receiving the rotation instruction, a target state of the rotation instruction, that is, a rotation state that the user wants to present on the display device, according to the current rotation state. If the current rotation state is a horizontal screen state, determining that the target state is a vertical screen state according to the fact that the angle of rotation of the display is 90 degrees; and if the current rotation state is the vertical screen state, determining that the target state is the horizontal screen state according to the fact that the angle of rotation of the display is 90 degrees every time.
In some embodiments, after determining the target state, the display device may obtain a play address corresponding to the target state from the asset information of the target asset. Taking the target state as the vertical screen state as an example, the vertical screen video stream of the target medium resource may be referred to as a second video stream, the playing address of the second video stream may be referred to as a second playing address, and if the second playing address can be obtained, the second video stream is obtained from the second playing address, in order to ensure the continuous playing effect, after the vertical screen video stream is acquired, the play progress before rotation can be quickly positioned by the seekTo () method of the MediaPlayer object, then, the play () method of the MediaPlayer object is called, the second video stream is played from the play time corresponding to the play progress, therefore, the user can see that the target media asset continues to be played from the playing progress before the display device rotates, the playing effect can be seen in fig. 10, and as can be seen from fig. 9 to 10, if the user inputs a rotation instruction when the playing reaches 03:43, the user continues to play from 03:43 after the display device rotates.
In some embodiments, if the second play address is not acquired, the long connection of the first video stream is maintained, and the acquisition and play of the first video stream is continued after the rotation into place.

In some embodiments, if the target state is the vertical screen state, but the display device cannot detect the second play address in the media information of the target media asset, the first video stream is continuously loaded from the original play address, i.e., the first play address. After a video stream is requested and a video frame is analyzed, the video stream is played in a small window form, at the moment, the width of the small window can be the same as that of a display in a vertical screen state, the small window is displayed in the middle of the display, and black edges exist on the upper side and the lower side of the small window.
In some embodiments, if there is no second play address, when the landscape state is converted into the portrait state, a scaling factor of the video frame is determined according to a width of the media asset in the horizontal direction and a resolution of the display in the short side direction, and the video frame of the first video stream is scaled according to the scaling factor.
In some embodiments, if there is no second play address, when the portrait screen state is converted into the landscape screen state, a scaling factor of the video frame is determined according to a height of the media asset in the vertical direction and a resolution of the display in the short side direction, and the video frame of the first video stream is scaled according to the scaling factor.
In some embodiments, during the horizontal-vertical screen conversion process, the display coordinate parameters of the display screen need to be exchanged in horizontal and vertical coordinates.
In some embodiments, if the target state is the vertical screen state, but the display device cannot detect the second play address in the media information of the target media asset, the playing of the first video stream may also be exited, and then the preset interface is displayed. In some embodiments, the preset interface may be provided with a prompt for prompting the user to view the target asset in the landscape state.
The above embodiment shows a resume method when a server issues media asset information containing at least one play address in advance, in other embodiments, the server may establish a mapping relationship between the media asset and at least one play address when the media asset is stored in the storage, when the media asset information is sent to the display equipment, the mapping relation is not sent, or only a default playing address is sent, if in the process of playing the target media asset by the display equipment, the user inputs a rotation instruction, the display device can send a media resource address request to the server according to the mismatching of the target state and the video stream corresponding to the current playing address, the media asset address request can comprise a target state and a media asset identifier of the target media asset, the server can issue a second playing address matched with the target state to the display equipment according to the mapping relation, and the display equipment loads a second video stream by going to the second playing address.
In some embodiments, the display device may request the server for the second play address during the rotation of the display to contend for time for loading of the second video stream, so that the second video stream can be played immediately after the rotation of the display is completed, and the second video stream can be played only after a long time is required after the rotation of the display is completed.
In some embodiments, one play address of the target media asset has two mapping relationships, which respectively correspond to a resource of the first video stream and a resource of the second video stream, and the display device may also select the corresponding mapping relationship to load the second video stream according to the target state being a vertical screen state.
As can be seen from the above embodiments, when a first video stream of a target asset is played, if the rotation state of the display changes, a second video stream of the target asset can be continuously played from the current playing progress, where the second video stream is a video stream matched with the rotated rotation state, so as to improve the playing effect of the target asset.
