[0034] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0035] In existing technologies, when a terminal device is playing multimedia content, the content can be cast to other devices by triggering a screen mirroring switch. However, the screen mirroring switch is usually not located in the multimedia content playback window, but rather in the control panel. The control panel can be displayed by long-pressing the playback window or by other operations. Every time a user wants to cast multimedia content, they need to first display the control panel and then trigger the screen mirroring switch within it. This process is cumbersome and inconvenient, especially when the user needs to switch the multimedia content to be cast.

[0036] To address the aforementioned technical issues, this disclosure provides a method for casting multimedia content to the target device. When the current device is not casting to the target device, a first panel is displayed in the playback window of the current device, triggering a first casting control within the first panel to cast the currently playing multimedia content in the playback window to the target device for playback, thus initiating the casting mode. After the casting mode is activated, a second casting control is displayed in the playback window for casting control. This allows for convenient and quick casting control, simplifying the casting operation, meeting users' personalized casting needs, and improving the user's casting experience.

[0037] The application scenarios of the multimedia content casting method disclosed herein are as follows: Figure 1a As shown, it includes a current device and a target device. The current device can be a terminal device such as a mobile phone or tablet, while the target device is a device used for screen casting, such as a television. The current device can execute the multimedia content casting method disclosed herein. The interaction diagram is shown below. Figure 1b As shown, the first multimedia content is played in the playback window of the current device. The playback window is the window where the multimedia content is played on the current device. If the multimedia content is played in full-screen mode, the playback window can be a full-screen window; if the multimedia content is played in a non-full-screen mode, the playback window can be the actual window where the multimedia content is played on the current device. The user can perform trigger operations such as long-pressing on the playback window (e.g.,...). Figure 1b (Left illustration) The first panel is displayed in the playback window, and the first projection control (such as...) is displayed on the first panel. Figure 1b (Intermediate diagram); this triggers the first screen mirroring control, projecting the first multimedia content to the target device for playback, and displaying the second screen mirroring control (such as...) in the playback window. Figure 1b (See diagram on the right).

[0038] It should be noted that the user information and data involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation portals are provided for users to choose to authorize or refuse.

[0039] The following will provide a detailed description of the multimedia content projection method disclosed herein, with reference to specific embodiments.

[0040] refer to Figure 2 , Figure 2 This is a schematic flowchart illustrating a method for casting multimedia content according to an embodiment of this disclosure. The method of this embodiment can be applied to a terminal device, and the method for casting multimedia content includes:

[0041] S201. Play the first multimedia content in the playback window of the current device.

[0042] In this embodiment, the playback window of the current device can play any multimedia content, including but not limited to video, audio, images, and feed stream data. Screen mirroring is not currently being performed on the current device. The playback window is the window through which the multimedia content is played. If the multimedia content is played in full-screen mode, the playback window can be a full-screen window; if the multimedia content is played in a non-full-screen mode, the playback window can be the actual window through which the multimedia content is played on the current device.

[0043] S202. In response to the trigger command on the playback window, a first panel is displayed, on which a first projection control is displayed.

[0044] In this embodiment, when the current device (such as a mobile device) is not casting, if the user needs to cast the first multimedia content on the current device to a target device such as a smart TV or monitor, the user can trigger the playback window to display a first panel. This first panel can be the control panel of the playback window. Triggering operations include, but are not limited to, long-press commands, specific trajectory swiping commands, or other commands, or clicking commands on preset function buttons on the playback window. The first panel displays a first casting control, and may also display controls not limited to, playback speed adjustment controls, forwarding controls, etc. Figure 1b (See the middle diagram). During the playback of any multimedia content in the playback window, the first panel is usually not displayed in the playback window and is in a hidden state. The first panel can be displayed in the playback window by triggering the playback window.

[0045] The first panel can be a long-press panel or a share panel, such as the long-press panel corresponding to the first multimedia content. The long-press panel can also display other functional controls, such as auto-play controls and bullet screen controls. The share panel can also display share controls, etc.

[0046] S203. In response to the trigger command of the first screen casting control, the first multimedia content is cast to the target device for playback.

[0047] In this embodiment, after the first panel is displayed in the playback window, the user can trigger the first screen casting control in the first panel to cast the first multimedia content to the target device, thus realizing the activation of the screen casting mode, that is, the switch from no screen casting to screen casting. The specific screen casting process will not be described in detail here.

[0048] S204. Display the second screen mirroring control in the playback window.

[0049] In this embodiment, after the first multimedia content is cast to the target device, i.e., after the casting mode is activated, the user may have casting control needs, such as selecting other multimedia content to cast or controlling the playback of the currently cast first multimedia content. To facilitate user operation, a second casting control is displayed in the playback window. The second casting control is used for casting control and can specifically be used for one or more casting control functions, such as selecting to cast the second multimedia content or controlling the playback of the currently cast first multimedia content. This embodiment does not impose any restrictions. When the current device is not casting, the second casting control is not displayed in the playback window, which makes the playback window simpler, reduces obstruction of the playback window, and improves the user's experience of watching multimedia content on the current device. The second casting control is displayed in the playback window only after the casting mode is activated, providing convenience for the user to control casting without having to trigger the display of the first panel or perform casting control in the first panel.

[0050] The multimedia content casting method, device, and storage medium provided in this disclosure involve playing first multimedia content in a playback window of a current device; displaying a first panel with a first casting control on the first panel in response to a trigger command on the playback window; casting the first multimedia content to a target device for playback in response to a trigger command on the first casting control; and displaying a second casting control in the playback window. The first casting control initiates the casting mode, enabling the casting of the first multimedia content, and the second casting control is displayed in the playback window. This allows for convenient and quick casting control, simplifying the casting operation, meeting users' personalized casting needs, and improving the user's casting experience.

[0051] Based on the above embodiments, such as Figure 3 As shown, Figure 3 This is a schematic flowchart illustrating a method for casting multimedia content to a screen according to another embodiment of this disclosure. The method includes:

[0052] S301. Play the first multimedia content in the playback window of the current device;

[0053] S302. In response to the trigger command on the playback window, a first panel is displayed, on which a first projection control is displayed;

[0054] S303. In response to the trigger command of the first screen casting control, the first multimedia content is cast to the target device for playback;

[0055] In this embodiment, S301 to S303 are the same as S201 to S203, while S204, when the second projection control is displayed in the playback window, is specifically as follows:

[0056] S304. In response to a switching command on the current device, play the second multimedia content in the playback window and display the second projection control in the playback window.

[0057] In this embodiment, when the first multimedia content is projected to the target device for playback, the second projection control is not displayed in the playback window of the current device. In order to ensure that the current device can continue to watch other multimedia content or filter the multimedia content to be projected, the multimedia content can be switched on the current device while the target device continues to play the first multimedia content. After the multimedia content is switched on the current device, the second projection control is displayed in the playback window.

[0058] Specifically, users can switch multimedia content on the current device. For example, for feed stream data, users can switch multimedia content by swiping up and down (or left and right). For other types of multimedia content, corresponding switching operations can be used. The current device responds to the switching command by playing the second multimedia content on the current device, while the target device continues to play the first multimedia content. Maintaining the target device's continued playback of the first multimedia content requires controlling the current device to prevent the second multimedia content from being directly projected onto the target device during a multimedia content switch, or to prevent interaction between the current and target devices during a multimedia content switch. By continuing to play the first multimedia content on the target device and playing the second multimedia content on the current device, the multimedia content switching on the current device does not affect the projection status on the target device.

[0059] When switching to the second multimedia content in the current device's playback window, a second casting control can be displayed in the playback window. This second casting control is used to cast the second multimedia content to the target device for playback when triggered, making it easier for users to personalize their casting content selection.

[0060] Furthermore, after the second screen mirroring control is displayed in the playback window, it may also include:

[0061] S305. In response to the trigger command of the second screen casting control, the second multimedia content is cast to the target device for playback.

[0062] In this embodiment, if a user wishes to cast the second multimedia content, the second casting control can be triggered to cast the second multimedia content to the target device for playback, without having to trigger the display of the first panel and then trigger the first casting control in the first panel.

[0063] Optionally, after the current device projects the first multimedia content to the target device for playback, and before switching multimedia content, the projection playback control interface of the first multimedia content can be displayed on the current device (e.g., ...). Figure 4a (The rightmost interface diagram) shows that after the current device performs a screen mirroring operation on the first multimedia content, the playback window of the current device switches from playing the first multimedia content to displaying the screen mirroring playback control interface. This interface includes, but is not limited to, target device selection controls, end screen mirroring controls, continuous screen mirroring controls (for continuously mirroring multiple multimedia contents according to the current device's playlist), playback speed adjustment controls, playback progress adjustment controls, and image quality adjustment controls. Optionally, the screen mirroring playback control interface may also include the existing comment, favorite, like, and share controls from the first multimedia content's playback window, allowing users to continue commenting, favorited, liking, and sharing the first multimedia content on the current device. When a user needs to switch multimedia content on the current device, such as... Figure 4b As shown, similar to the usual swiping up and down or left and right to switch multimedia content, in this embodiment, the swiping operation can be performed on the screen projection playback control interface of the first multimedia content (e.g., Figure 4b The leftmost interface diagram shows that the swipe operation can be vertical or horizontal. In response to a swipe operation (such as vertical swipe) in the screen mirroring control interface of the first multimedia content, the current device switches the display of the screen mirroring control interface of the first multimedia content to the playback of the second multimedia content (such as...). Figure 4b(The middle interface diagram) allows switching multimedia content on the current device; simultaneously, a second casting control is displayed in the playback window of the second multimedia content. Optionally, the second casting control can float on the playback window of the second multimedia content and can be collapsed or hidden (e.g., expanded for a preset time, then collapsed or hidden, and can be expanded again by clicking or dragging). When the user triggers the second casting control, the second multimedia content can be cast to the target device for playback. The playback window of the current device can display the casting playback control interface of the second multimedia content (e.g., ...). Figure 4b (Screenshot of the interface on the far right).

[0064] Optionally, in another embodiment, in response to a first sliding operation command in the screen casting playback control interface of the first multimedia content, the current device switches from displaying the screen casting playback control interface of the first multimedia content to playing the second multimedia content in the playback window of the current device; in response to a second sliding operation command in the screen casting playback control interface of the first multimedia content (different from the first sliding operation command, for example, the first sliding operation is a vertical sliding command, and the second sliding operation command is a horizontal sliding command), the current device switches channels in the playback window, for example, switching from the current multimedia content channel to the shopping channel. Optionally, if the switched channel is another multimedia content channel, the second screen casting control continues to be displayed in the playback window; if the switched channel is not a multimedia content channel, the second screen casting control can be hidden, and when switching back to the multimedia content channel, the second screen casting control can be displayed again in the playback window; of course, if the switched channel is not a multimedia content channel, the second screen casting control can also continue to be displayed.

[0065] When the current device is not casting, the playback window may not include casting controls, making the playback window cleaner, reducing obstruction, and improving the user's experience of watching multimedia content on the current device. When the user needs to cast the first multimedia content, they can trigger the first panel by long-pressing the playback window or by other operations, triggering the first casting control within it to cast the first multimedia content, thus initiating casting mode. After casting begins, the second casting control only appears in the playback window after the multimedia content on the current device changes. The change of multimedia content on the current device does not affect the continued playback of the first multimedia content on the target device. When the user needs to cast the switched second multimedia content, they can trigger the second casting control without having to trigger the first panel and then the first casting control, simplifying the casting process. When the user does not need to cast the switched second multimedia content, the second casting control does not need to be triggered, and the user can continue playing the second multimedia content on the current device, or continue to switch multimedia content. The process for the switched third multimedia content is similar and will not be described in detail here. Of course, if the user switches back to the first multimedia content, the screen mirroring control interface of the first multimedia content can continue to be displayed on the playback window.

[0066] In one alternative embodiment, the second projection control includes at least two sub-controls, such as a first sub-control and a second sub-control.

[0067] The first sub-control is used to cast the multimedia content currently playing in the playback window of the current device to the screen, such as... Figure 5a As shown, if the second multimedia content is being played in the playback window of the current device, and the user triggers the first sub-control in the second screen casting control, the current device responds to the trigger command of the first sub-control in the second screen casting control and casts the second multimedia content being played on the current device to the target device for playback. The screen casting playback control interface of the second multimedia content can be displayed in the playback window of the current device.

[0068] The second sub-control is used to switch the playback window of the current device to the casting playback control interface of the multimedia content currently being played on the target device. When the user triggers the second sub-control in the second casting control, in response to the trigger command of the second sub-control, the playback window of the currently playing second multimedia content on the current device switches to the casting playback control interface of the multimedia content currently being played on the target device. Specifically, if the target device is playing the first multimedia content, then after the user triggers the second sub-control, the playback window of the current device switches from playing the second multimedia content to displaying the casting playback control interface of the first multimedia content. Figure 5bAs shown; in continuous screen casting mode, after the target device finishes playing the first multimedia content, it automatically switches to the next multimedia content in the playlist. At the same time, it can also notify the current device when the target device switches to the next multimedia content. If the target device is playing the fourth multimedia content after switching, the current device's playback window will switch from playing the second multimedia content to displaying the screen casting playback control interface of the fourth multimedia content after the user triggers the second sub-control in the second screen casting control.

[0069] Optionally, the first and second sub-controls in the second screen mirroring control of the current device can be in the form of buttons. Optionally, the second sub-control displays an identifier of the multimedia content currently being played on the target device, such as the publisher image of the multimedia content, the homepage image of the multimedia content, etc., so that users can determine which multimedia content is currently being played on the target device by observing the identifier in the second sub-control.

[0070] In another optional embodiment, the second screen casting control of the current device can be a control with the same function as the first sub-control described above. When the user triggers the second screen casting control, the current device responds to the trigger command of the second screen casting control and casts the second multimedia content that the current device is playing to the target device for playback.

[0071] In another optional embodiment, the second screen casting control of the current device can be a single control with the same function as the second sub-control described above. When the user triggers the second screen casting control, the current device responds to the trigger command by switching the playback window of the current device from the currently playing second multimedia content to the screen casting playback control interface displaying the multimedia content currently playing on the target device. If the user needs to cast the second multimedia content, they can trigger the display of the first panel through long-press or other operations, and trigger the first screen casting control on the first panel to achieve the screen casting of the second multimedia content.

[0072] In another alternative embodiment, such as Figure 6 As shown, S305, responding to a trigger command on the second projection control, and projecting the second multimedia content onto the target device for playback, may include:

[0073] S501. In response to the trigger command of the second projection control, the playback window is switched from playing the second multimedia content to displaying the projection playback control interface of the multimedia content currently being played by the target device, and the second multimedia content is played in a floating window above the playback window.

[0074] S502. In response to the trigger command for the floating window, the second multimedia content is projected onto the target device for playback.

[0075] In this embodiment, after the user triggers the second screen casting control, the playback window returns to the screen casting playback control interface of the multimedia content currently being played on the target device. That is, the playback window switches from displaying the second multimedia content to displaying the screen casting playback control interface of the multimedia content currently being played on the target device. Figure 7 Assuming the target device is currently playing the first multimedia content, after triggering the second casting control in the playback window of the second multimedia content, the playback window switches from playing the second multimedia content to displaying the casting playback control interface of the first multimedia content. However, the casting playback control interface of the first multimedia content cannot display the second multimedia content, making it inconvenient for the user to continue watching the second multimedia content on the current device. Therefore, in this embodiment, the second multimedia content is played in a floating window (such as a small window) above the casting playback control interface of the first multimedia content. Figure 6 (See the middle interface diagram). This floating window is above the playback window.

[0076] When playing secondary multimedia content through a floating window, if the user needs to cast the secondary multimedia content to a target device, the user can trigger the floating window. The current device responds to the trigger command by casting the secondary multimedia content to the target device for playback. The current device can then display the casting playback control interface for the secondary multimedia content. In other words, the floating window not only has playback functionality but also functions as a secondary casting control. Alternatively, a separate control can be set to trigger casting.

[0077] To inform users that screen casting can be triggered by opening a floating window, a specific animation effect can be used to transform the second screen casting control into a floating window when responding to the trigger command of the second screen casting control and playing the second multimedia content in the floating window. While the second multimedia content is playing in the floating window, a prompt message can also be displayed in the floating window to inform the user that screen casting can be achieved by triggering the floating window. For example, the prompt message could be "Click to cast" or "Click to cast the current multimedia content".

[0078] Furthermore, after the user triggers the floating window to cast the second multimedia content to the target device for playback, the floating window can be closed; of course, the floating window can also remain open, meaning that the second multimedia content will play simultaneously in the floating windows of both the target device and the current device, facilitating user control of the casting playback. Optionally, the playback progress of the second multimedia content in the floating window can be ensured to be the same as that of the second multimedia content played on the target device, so that the user can control the casting playback on the target device based on the second multimedia content in the floating window above the casting playback control interface.

[0079] Based on any of the above embodiments, such as Figure 8As shown, S202, responding to a trigger command on the second projection control, projects the second multimedia content onto the target device for playback, including:

[0080] S701. In response to the trigger command of the second screen projection control, identify the type of the second multimedia content;

[0081] S702. If the type of the second multimedia content is a multimedia content type that supports screen casting, then the second multimedia content is cast to the target device for playback.

[0082] In this embodiment, not all multimedia content can be cast. Certain preset types of multimedia content cannot be cast. Therefore, after triggering the second casting control, the type of the second multimedia content is identified. If the type of the second multimedia content belongs to the type of multimedia content that supports casting, the second multimedia content will be cast to the target device for playback. Otherwise, if the type of the second multimedia content does not belong to the type of multimedia content that does not support casting, the casting of the second multimedia content to the target device will be stopped, and a prompt message indicating that the second multimedia content does not support casting will be displayed on the current device.
