Embodiment 1

[0075] see figure 1 , is a schematic diagram of a hardware structure of a terminal device according to an embodiment of the present invention.

[0076] The terminal device 100 in this embodiment of the present invention includes: a detection connection unit 101 , a control unit 102 , and a display unit 103 .

[0077] When the terminal device 100 is used as the projection side (Source end):

[0078] The detection connection unit 101 is used to perform device discovery to search for other adjacent devices available with Wi-Fi display service. When other devices are discovered, the detection connection unit 101 interacts with other devices and negotiates capabilities through the RTSP protocol, so that the device 100 is connected to other devices.

[0079] The control unit 102 controls basic operations within the terminal device 100 . Specifically, the control unit 102 controls so that the content (screen data) displayed by the display unit 103 is sent to other devices through ...

Embodiment 2

[0106] In this embodiment, in addition to displaying the received screen data, the receiving-side device can also control the projection-side device.

[0107] Specifically, the receiving side device further includes: an input device 104, configured to generate an input signal according to a user's operation, and transmit the input signal to the control unit. The input signal includes information such as coordinates and duration of the input point.

[0108] When the receiving side device receives and displays the screen data of the projecting side device, the control unit detects an input signal generated through the input device.

[0109] In one embodiment, in order to enable the projection side device to correctly identify the input operation, the control unit converts the coordinates of the input points contained in the input signal according to the physical parameters of the input device. For example, if the input device is a touch screen with a width of W0 and a height of...

Embodiment 3

[0119] On the basis of the above-mentioned embodiment 1 or 2, in order to enable the receiving device to freely control the device when receiving and displaying the screen data of the projection device, the screen data and the interface of the device are displayed separately in a split-screen manner .

[0120] It should be understood that splitting the screen divides the display screen of the receiving device into a first display area and a second display area, and correspondingly divides the input device into an input area corresponding to the first display area and an input area corresponding to the second display area. area, this is the prior art, and will not be repeated here. In this embodiment of the present invention, on the basis of split screens, any display area in the split screens can be used to display received screen data.

[0121] see Figure 8 , after adopting split-screen display, device B, device C and device D all use any display area to display the screen...

Abstract

The invention discloses a multi-screen projection control method and system and a terminal device. The method comprises the following steps: sending a discovery request from a first device; receiving one or more discovery responses at the first device, wherein the discovery responses are sent from one or more second devices with response to the received discovery request; establishing WFD connection between the first device and the one or more second devices; and transmitting screen data of the first device to the one or more second devices based on the established WFD connection. The beneficial effects are that one-to-many screen projection and sharing can be realized; through the WFD network, dependence on sites can be reduced; and the multi-screen projection control method and system and the terminal device can be applied to scenes of special demands, such as multimedia conference rooms or audio-video function classrooms, realize quick WFD network establishment and realize resource sharing.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a multi-screen projection control method, system and terminal equipment. Background technique [0002] With the rapid popularization of smart devices, making full use of the interaction between smart devices and equipment to realize communication and cooperation between people is a mainstream trend to achieve diversified communication. [0003] The Wi-Fi display network is a network system recommended by the Wi-Fi Alliance to enable Wi-Fi devices to connect to each other in a peer-to-peer manner without participating in a home network, office network, or hotspot network. [0004] The existing P2P-based Wi-Fidisplay (WFD) technology can realize one-to-one screen sharing between devices. [0005] However, screen sharing in the prior art is limited to "one-to-one" sharing, which is a one-way sharing and passive communication. [0006] Therefore, there are d...
