Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
The terms "first" and "second," etc. in this disclosure are used to distinguish between different objects, rather than to describe a particular order of objects. For example, the first display interface and the second display interface, etc. are used to distinguish different display interfaces, rather than to describe a particular order of display interfaces.
Currently, multi-screen interaction is a common scenario in the display field, for example, content interaction between a device with a small screen (such as a mobile phone, a notebook computer, etc.) and a device with a large screen (such as a television). Cell phones are generally based on two operating systems: the iOS operating system and the Android (Android) operating system. In an iOS operating system, the functions of screen projection and mirror image of the mobile phone can be realized through a defined Airplay protocol (private protocol); in the Android system, the mobile phone can be used for screen projection through a defined Digital Living Network Alliance (DLNA) protocol, and screen images or audio contents on the mobile phone can be mirrored to nearby equipment through WiFi direct connection based on Miracast. The smart television or the television externally connected with the set-top box can interact with the mobile phone through the Airplay protocol and the DLNA protocol, so that a multi-screen interaction (mainly screen projection) function is realized, and a screen projection function can also be realized through other protocols, which is not specifically limited in this embodiment.
The remarking is a method for commenting and annotating the content of a multimedia file, such as a presentation (PPT) or an Excel form, so that a user can more easily master the content of the file. The annotation has a specific application in many scenes, for example, in a meeting scene, the core requirement is to be able to project a user document and to annotate a description at any time during the course of a speech. The embodiment of the disclosure is mainly suitable for the situation that a user cannot annotate the content displayed by the display device directly through touch operation.
It should be noted that: the touch device in this embodiment may be understood as a device having a touch screen, and the display device mainly refers to a non-touch device, that is: and devices without touch screens, such as multimedia devices or televisions. The touch screen may include: a capacitive screen, an electromagnetic screen, an infrared screen, etc., which is not limited in this embodiment.
In some technologies, when the display device cannot annotate the displayed content directly through touch operation, the display content of the display device is sent to a terminal, when a user marks on the terminal, the annotation handwriting is directly drawn in a canvas layer of the terminal, the annotation trajectory is projected to the display device and is displayed for the user to watch, but the problem of lagging of the annotation handwriting easily occurs under the conditions of poor wireless environment and poor hardware resources by the method, so that inconvenience is brought, and the user experience is reduced.
In order to solve the above problem, the present disclosure may first use a screen projection function or a screen recording function to mirror the content of the display device to the touch device, so that the touch device mirrors the display content of the display, and then the controller of the display device receives touch information sent by the touch device, where the touch information includes: the display device comprises a touch operation event and position information corresponding to the touch operation event, annotation content corresponding to the touch information is drawn on display content of the display based on the touch operation event and the position information corresponding to the touch operation event, the display is controlled to display the annotation content, and through interaction between the touch device and the display device, when a user cannot annotate the display device directly through touch operation, the corresponding annotation content is drawn on the display content of the display device and the annotation content is displayed.

In some embodiments, the method may further specifically include:
after the display displays the annotation window, setting characteristic attributes corresponding to the annotation symbols in the annotation window;
and drawing annotation content corresponding to the touch information on the annotation window according to the characteristic attribute.
The annotation symbol may be understood as each symbol for annotation displayed when the annotation function is activated, such as a brush, a pencil, a straight line, a rectangle, a circle, an arrow, and the like. The characteristic attribute can be understood as the characteristics such as color and thickness corresponding to the annotation symbol.
Specifically, after the display displays the annotation window, the controller can also set a characteristic attribute corresponding to the annotation symbol in the annotation window, so that the annotation content corresponding to the touch information is drawn on the annotation window according to the set characteristic attribute.
For example, assuming that the annotation symbol is a brush, the characteristic attribute is red, and the thickness is a numerical value a, when the annotation content corresponding to the touch information is subsequently drawn on the display content of the display, the annotation content with a red line and a numerical value a is drawn by using the brush.
In some embodiments, the characteristic attribute corresponding to the annotation symbol may be a default color and a default thickness set by the controller after starting the annotation window and performing an initialization operation; the characteristic attribute corresponding to the annotation symbol may also be determined by the user by operating the touch device, and the touch device sends the determined characteristic attribute corresponding to the annotation symbol to the display device.
For example, the touch device may send the characteristic attribute corresponding to the determined annotation symbol to the display device in a form of a character string through a TCP command. Wherein, the color in the character string can be as follows: starting with PULLMIRROR _ PAINTBRUSHCOLOR, the coarseness in the string may start with PULLMIRROR _ PAINTBRUSHWIDTH.
In some embodiments, after the display device receives the characteristic attribute corresponding to the annotation symbol sent by the touch device, a comment window can be restarted to be distinguished from the original comment window, and meanwhile, the characteristic attribute of the restarted comment window is set, so that real-time color changing comment can be realized, the comment experience of a user is increased, and the comment scene is enriched.
In some embodiments, the display device may receive the characteristic attribute and the touch information through onTouchEvent.
In some embodiments, the method may further specifically include:
receiving a touch ending command sent by the touch equipment;
and removing the annotation window and annotation contents corresponding to the annotation window according to the touch control ending command.
Specifically, the controller of the display device can also receive a touch ending command sent by the touch device, and remove the annotation window and the annotation content corresponding to the annotation window according to the touch ending command.
In this embodiment, after the annotation is finished, the display content of the display can be restored to the original multimedia content by the above method.
In some embodiments, the process of mirroring the display content of the display device to the touch device and controlling the display device to annotate through the touch device may be applied to the following scenarios:
1. after sale, remote connection can be realized, when a user cannot use a certain function, the user can be remotely annotated to guide the user to operate at the television end, and the effect that the user cannot be helped to solve the problem is achieved;
2. when the television is mirrored to the mobile phone end, the mobile phone end is annotated to realize a picture with highlighted key annotation content.
In some embodiments, when the display device is mirrored to the touch device, the user may store the annotation content displayed in the touch device through a menu bar option of the touch device, for example, by means of screen capture, and may share the stored data, so that other users may also see the annotation content.
In some embodiments, when the touch device is mirrored to the display device, since the touch device can annotate directly through touch operation, a user can first operate a menu bar of the touch device to select an annotation function, and then the touch device starts a window service (WindowService) to set an annotation window having a transparent property and floating on the uppermost layer of display content of the touch device, and according to the real-time touch operation of the user, the display device obtains a real-time motion trajectory and draws corresponding annotation content in the annotation window. At this time, the real-time data stream during drawing the annotation content in the touch device can be transmitted to the display device for display through the local area network or the wide area network. Meanwhile, when the annotating window is started, the touch control equipment needs to capture a focus, so that the operation of an original control device (such as a remote controller) is not influenced, and other operations of the display equipment can be performed while annotating, so that the use scene is wider.
To sum up, the present disclosure executes the annotation method on the display device, and first receives touch information sent by the touch device, where the touch device displays display content of the display in a mirror image manner, and the touch information includes: the display device comprises a touch operation event and position information corresponding to the touch operation event, annotation content corresponding to the touch information is drawn on display content of the display based on the touch operation event and the position information corresponding to the touch operation event, the display is controlled to display the annotation content, and through interaction between the touch device and the display device, when a user cannot annotate the display device directly through touch operation, the corresponding annotation content is drawn on the display content of the display device and the annotation content is displayed.
