The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0028] The screen projection method and device of cabin KTV multi-screen interaction of the embodiments of the present application are described below with reference to the accompanying drawings. In view of the problems mentioned in the above background art, the present application provides a screen projection method of cabin KTV multi-screen interaction, in which the screen projection mode of a target vehicle is started to newly create and display an activity interface in the rear row of the target vehicle. Every other preset time, the current video frame bitmap is obtained from the playing TextureView of the KTV main interface of the front row driver screen of the target vehicle, and the bitmap object corresponding to the current video frame bitmap is drawn into the canvas of the play control of the rear row interface, and the canvas is drawn into the TextureView of the rear row for rendering to obtain corresponding rendering data. Based on the rendering data and the activity interface, the rear row interface and the KTV main interface of the front row driver screen are synchronized for video source playing. The present application can realize the display of video content on other screens by projecting only the video content onto other screens, realize the special customization and differentiation of the menu interface according to the position of the screen, and greatly enrich the user interaction content of multi-screen hardware. Thus, the problem that the vehicle-mounted KTV multi-screen interaction in the prior art can only project but cannot perform independent menu operation is solved.

[0029] Specifically, Figure 1 A flowchart of the screen projection method of cabin KTV multi-screen interaction provided by the embodiments of the present application is shown in FIG. 1.

[0030] As Figure 1 shown, the screen projection method of cabin KTV multi-screen interaction includes the following steps:

[0031] In step S101, the screen projection mode of a target vehicle is started to newly create and display an activity interface in the rear row of the target vehicle.

[0032] In step S102, every preset time, a current video frame picture bitmap is acquired from a playing TextureView of a KTV main interface of a front-row main driver screen of a target vehicle, a bitmap object corresponding to the current video frame picture bitmap is drawn into a canvas of a playing control of a rear-row interface, and the canvas is drawn into a TextureView of the rear row for rendering to obtain corresponding rendering data.

[0033] In the embodiment of the present application, the main interface of the KTV on the front-row main driver screen is combined with TextureView and an android mediaplayer in the activity, and a menu operation interface is arranged on the playing layout.

[0034] Firstly, the embodiment of the present application can click a screen projection button to newly create an activity interface in the rear row and display in the rear row. Figure 2 As shown in the figure, the embodiment of the present application can acquire a playing frame picture from a playing TextureView of the front row by a per-second timing operation (such as a timing task operation more than 30 times per second), copy a bitmap, draw the bitmap into a canvas of a playing control of a current rear-row interface, draw the canvas into a TextureView of the rear row for rendering, and thus obtain video data of the rear row.

[0035] Optionally, in an embodiment of the present application, before acquiring a current video frame picture bitmap from a playing TextureView of a KTV main interface of a front-row main driver screen of a target vehicle every preset time, the method further comprises: acquiring a SurfaceTexture object from a TextureView of a rear-row interface based on a preset getSurfaceTexture() calling strategy; locking a canvas of the TextureView by a preset lockCanvas() strategy and the SurfaceTexture object, and acquiring a canvas object; determining a width and a height of the TextureView, and constructing a blank bitmap object according to the width and the height.

[0036] It should be noted that the embodiment of the present application can acquire a SurfaceTexture object from a rear-row TextureView by calling a getSurfaceTexture() method; secondly, the embodiment of the present application can lock a canvas of the TextureView by using a lockCanvas() method, and acquire a canvas object for subsequent drawing operation.

[0037] Afterwards, the embodiment of the present application can create a blank Bitmap object according to the width and height of the TextureView, for storing the copied content.

[0038] Thus, the embodiment of the present application provides reliable data support and basis for obtaining the rear video data by constructing a blank bitmap object.

[0039] Optionally, in an embodiment of the present application, every preset time, the current video frame bitmap is obtained from the playing TextureView of the KTV main interface of the front row main driver screen of the target vehicle, the bitmap object corresponding to the current video frame bitmap is drawn into the canvas of the playback control of the rear row interface, and the canvas is drawn into the rear row TextureView for rendering to obtain corresponding rendering data, including: using the canvas object, the content of the playing TextureView of the KTV main interface of the front row main driver screen is drawn into the bitmap object; based on the preset unlockCanvasAndPost(canvas) strategy, the canvas of the TextureView is unlocked to render in the rear row TextureView through the canvas of the TextureView to obtain the rendering data.

[0040] In actual execution process, the embodiment of the present application can use the obtained canvas object to draw the content of the front row TextureView into the created Bitmap object; after the drawing is completed, the embodiment of the present application can call the unlockCanvasAndPost(canvas) method to unlock the canvas of the TextureView, and submit the drawing operation to the rear row TextureView to render in the rear row TextureView through the canvas of the TextureView, so as to obtain the rendering data.

[0041] In step S103, based on the rendering data and the activity interface, the rear row interface is synchronized with the KTV main interface of the front row main driver screen for video source playback.

[0042] Afterwards, the embodiment of the present application can superimpose the rear row operation menu interface on the basis of the video playback space of the rear row, so as to customize the independent operation interface of the rear row.

[0043] Thus, under the premise of single host hardware, the embodiment of the present application does not excessively rely on the host hardware resources, realizes the front row and rear row video stream sharing synchronization and menu operation interface independence, and meets the scene of video stream synchronization watching and independent use of users.

[0044] Optionally, in an embodiment of the present application, based on the rendering data and the activity interface, the rear interface is synchronized with the KTV main interface of the front row driver screen for video source playing, including: superimposing the activity interface and the rendering data to construct an independent rear interface, so that the rear interface is synchronized with the video in the KTV main interface of the front row driver screen for playing.

[0045] It should be noted that, as Figure 3 shown, in an embodiment of the present application, the front row video playing activity interface, the video stream playing carrier is a textureview control, the decoding and loading of the video playing is an android native mediaplaer, and the decoded video stream is played on the textureview control; a playing control component is superimposed on the textureview control, including a play / pause, a first / previous control, a playlist, a screen projection and other operation menu control interfaces, for the front row user to operate and control.

[0046] As Figure 4 shown, the layout of the playing interface of the rear screen is similar to the above layout, that is, the textureview control in an activty is superimposed with the operation layout interface of the rear row last time, and the layout interface is different from the front row, and the rear interface does not have a mediaplaer to load and decode the video source.

[0047] Therefore, during the playing of the front row video, the screen projection button of the front row is clicked, and the rear interface and the front interface can be synchronized and displayed through the above process; the picture is synchronized and displayed, the menu can be independently operated, and various multi-screen interaction scenes can be realized, such as the front row ordering songs and singing, the rear row can continue to order songs and operate the atmosphere of the singing room, and the menus of multiple screens are independent and do not interfere with each other.

[0048] In summary, in the embodiments of the present application, only the video content is projected onto other screens, such as the front row being projected onto the rear row and the rear row being projected onto the front row, which greatly enriches the user interaction content of the multi-screen hardware, so that the video content can be displayed on other screens, and the menu interface is specially customized and differentiated according to the position of the screen; the screen projection behavior initiated by the front row screen of the vehicle-mounted KTV in the embodiments of the present application can project the song MV picture to the rear row, and the lyrics and the picture are synchronized, the user of the front row operates the song ordering menu, at the same time, the passengers of the rear row are not affected, and can continue to see the playing picture and the lyrics to sing normally, and the passengers of the rear row can order songs / cut songs according to their own needs, and even increase the atmosphere operation for the front row user to sing.

[0049] According to the screen projection method for multi-screen interaction in a cabin KTV proposed in this application, the screen projection mode of the target vehicle is activated to create and display an activity interface in the rear row of the target vehicle. At preset intervals, the current video frame bitmap is obtained from the playback TextureView of the KTV main interface on the front driver's screen of the target vehicle, and the bitmap object corresponding to the current video frame bitmap is drawn onto the canvas of the playback control on the rear interface. The canvas is then drawn onto the TextureView in the rear for rendering to obtain the corresponding rendering data. Based on the rendering data and the activity interface, the rear interface and the KTV main interface on the front driver's screen are synchronized for video source playback. This application, by projecting only the video content onto other screens, enables the video content to be displayed on other screens, allowing the menu interface to be customized and differentiated according to its location on the screen, greatly enriching the user interaction content of the multi-screen hardware.

[0050] Secondly, the screen projection device for multi-screen interaction in a cabin KTV according to an embodiment of this application is described with reference to the accompanying drawings.

[0055] The playback module 300 is used to synchronize the video source playback between the rear-seat interface and the KTV main interface on the driver's screen in the front row, based on rendering data and the activity interface.

[0056] Optionally, in one embodiment of this application, the playback module 300 includes: an overlay unit for overlaying the activity interface and rendering data to construct an independent rear-seat interface so that the rear-seat interface can be played synchronously with the video in the KTV main interface on the driver's screen in the front row.
