Fig. 1 schematically shows a schematic diagram of an application scenario of a control method according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, in a multi-user scenario, there are multiple personal devices, e.g., personal device 121, personal device 122. Each personal device has access to a control means, such as control means 111 and control means 112, for example, control means 111 is connected to personal device 121 and control means 112 is connected to personal device 122. Wherein the personal device and/or a control device connected to the personal device may be communicatively connected to the presentation device 130 to implement the screen projection function.
The control device is provided with at least one input unit, such as at least one key, and when a user presses the key, the content displayed on the personal device is put on the display device to be shared with other users. A plurality of input units may be provided on the control device to implement different control instructions, or one input unit on the control device may generate different control instructions in response to different control operations.
The control method and the display method of the embodiment of the present disclosure are described below with reference to fig. 2 and 3.
Fig. 2 schematically shows a flow chart of a control method according to an embodiment of the disclosure.
As shown in fig. 2, the method includes operations S210 and S220.
In operation S210, a user operation is obtained.
In operation S220, a screen-casting request is transmitted to the presentation apparatus or transmitted to the presentation apparatus through the personal apparatus based on the user operation, such that content presented in a presentation area of the presentation apparatus is changed from first content to second content, the second content including screen-casting content of the personal apparatus.
Fig. 3 schematically shows a flow chart of a presentation method according to an embodiment of the present disclosure.
As shown in fig. 3, the method includes operations S310 to S330.
In operation S310, first content is presented in a presentation area of the presentation apparatus.
In operation S320, in a case where the control apparatus detects a specific user operation, a screen-casting request transmitted by the control apparatus or a personal device connected to the control apparatus is received.
In operation S330, in response to the screen-casting request, the display area is controlled to display second content including screen-casting content of a personal device connected to the control apparatus.
For example, the user may press a key on the control device, and after the control device obtains the user operation, the control device performs operation S220 to send a screen-casting request to the display device or send a screen-casting request to the display device through the personal device. When the display device receives the screen projection request, the first content is being displayed in the display area, and according to the embodiment of the disclosure, the first content may include screen projection content of other personal devices, or may be content transmitted to the display device through another signal line, for example, content obtained from an HDMI interface. And the display equipment responds to the received screen projection request and controls the display area to display the screen projection content of the personal equipment connected with the control device.
The method can realize the technical effect that a plurality of users conveniently cast screens on the same display equipment through simple user operation.
The method of the embodiment of the present invention can also solve the conflict problem of simultaneous screen projection by multiple people, and the method of the embodiment of the present disclosure is described below with reference to fig. 4A and 4B.
Figure 4A schematically illustrates a schematic view of a display device according to an embodiment of the disclosure.
As shown in fig. 4A, the display area 40 of the display device has a first area 41 and a second area 42. In a general case, the first area 41 and the second area 42 may be used together to present one presentation. In other scenarios, the first area 41 and the second area 42 may respectively display different contents, forming a split screen mode. According to the embodiment of the present disclosure, the display area 40 may not be limited to two split-screen areas during the display process, and for example, may be divided into 3, 4, 6 or even more split-screen areas.
Fig. 4B schematically illustrates a schematic diagram of a control and presentation method according to another embodiment of the present disclosure.
As shown in fig. 4B, the method includes operations S410 to S460.
In operation S410, the control device or the personal device transmits a screen-casting request to the presentation device, and the presentation device obtains the screen-casting request.
In operation S420, the presentation apparatus determines whether the screen-casting request is a first-type screen-casting request or a second-type screen-casting request. For example, when the user operation is a first type of user operation, the control device or the personal device sends a first type of screen projection request to the display device, and when the user operation is a second type of user operation, the control device or the personal device sends a second type of screen projection request to the display device. According to the embodiment of the present disclosure, the first type of user operation may be, for example, a long press operation in which the pressing time is longer than a threshold, and the second type of user operation may be, for example, a short press operation in which the pressing time is shorter than the threshold. In the case that the screen-casting request is the first-type screen-casting request, performing operation S430; in the case where the screen-casting request is the second type of screen-casting request, operation S440 is performed.
In operation S430, the presentation device stops presenting the first content in the presentation area to present the screen-shot content of the personal device. For example, when a user presses a button of the control device for a long time to send a first type screen projection request, all contents being displayed are cleared no matter whether the display in the display area of the display device is in a split screen state, so that the screen projection contents of the personal device are displayed by using the whole display area.
In operation S440, the presentation apparatus determines whether the presentation area is in a split screen state, and presents the second content based on the current state. Specifically, in case that the presentation area presents the first content from one signal source in the non-screen mode, operation S450 is performed; in a case where the presentation area presents the first content from the plurality of signal sources in the screen-division mode, operation S460 is performed.
In operation S450, the display device switches the display area to a split-screen mode including at least two split-screen areas to display the second content, where the second content includes the first content from the signal source and the screen-shot content of the personal device, and the at least two split-screen areas are respectively used for displaying the first content from the signal source and the screen-shot content of the personal device. For example, upon obtaining the screen-cast request, the presentation device is presenting content from the HDMI signal in a non-screen mode, in response to obtaining the screen-cast request, the presentation area is switched to a split-screen mode, the content from the HDMI signal is presented using the first area, and the screen-cast content of the personal device is presented using the second area.
In operation S460, the screen-shot content of the personal device is presented in at least one of a plurality of screen-divided areas.
According to the embodiment of the disclosure, in the case that at least one idle split screen area exists in the plurality of split screen areas, the screen-casting content of the personal device is displayed in the idle split screen area.
According to another embodiment of the disclosure, in a case that no idle split screen area exists in a plurality of split screen areas, displaying content displayed in one split screen area is stopped to display screen-cast content of the personal device.
For example, in a case where there is no free split screen area in the plurality of split screen areas, one split screen area may be determined as a target area based on the priority and/or time sequence of the content displayed in the plurality of split screen areas, and the content displayed in the target area may be stopped from being displayed to display the screen-shot content of the personal device.
For example, different priorities may be set for personal devices of different users, allowing for overlay of the projected content of the device with the lower priority among the currently presented projected content. Or, when the display device has an input of one path of HDMI signal, the screen projection content of other personal devices is always covered, but the content of the HDMI signal is not covered. Alternatively, in the case where a plurality of screen-cast contents are presented in a plurality of split screen areas, the screen-cast contents that are first started to be presented may always be overlaid. Of course, suitable rules may be set, such as determining which display content to overlay by way of weighting, using the above priority and chronological factors in combination.
Based on the same inventive concept, the present disclosure also provides a control system and a display system, and the control system and the display system of the embodiments of the present disclosure are described below with reference to fig. 5 and 6, respectively.
