Thereafter, the user may push on the screen shown in fig. 5, the touch screen display 501 sends the touch data to the push and display terminal 601, the display touch acquisition module of the push and display terminal 601 (e.g. analyzes different touch results including touch objects, touch directions, and touch gestures based on the previously implemented association settings), and sends the analysis result to the push command packaging module 6004. The push instruction packing module 6004 determines different push instructions (for example, determines a signal source screen to be pushed according to a touch object, determines a target terminal according to a touch direction, and determines a display mode according to a touch gesture) according to different analysis results, and packs. The pushing instruction may include information of a signal source picture to be pushed selected by a pushing operation based on signal source picture summary information (such as information of the signal source picture to be pushed selected by performing a touch operation on the signal source picture summary information diagram shown in fig. 5), a target terminal 602 to which the signal source picture to be pushed is to be pushed, a display manner of the signal source picture to be pushed on the target terminal 602 may include a full screen picture display, a reduced display, a display at a certain grid position, or when the signal source picture to be pushed includes multiple signal sources (signal sources 701 and 702) at the same time, the signal source pictures are displayed together at different grid positions in a certain distribution manner, such as a left-right distribution or an up-down distribution. The pushing action corresponds to an action corresponding to an input for generating pushing data, and a user can select one or more signal source pictures to be pushed from the signal source picture summary list through the input, namely the pushing action.
When the input device includes a somatosensory pushing device, the pushing and displaying terminal 601 may set a somatosensory pushing direction to be associated with a target terminal in the direction in advance, and associate a somatosensory pushing action mode with a display mode, and associate a somatosensory pushing action object with a signal source screen to be pushed; alternatively, when the input device includes a mouse, the pushing and displaying terminal 601 may associate the moving direction of the mouse with the target terminal (such as the pushing and displaying terminal 602), associate the clicking mode with the displaying mode, and associate the selected object of the mouse with the signal source screen to be pushed.
The push instruction packing module 6004 sends the packed push instruction to the network instruction sending module 6005, and the network instruction sending module 6005 sends the push instruction to the server 900.
The server 900 receives the push instruction, determines a target encoded video stream address corresponding to the information (such as the signal source picture ID) of the signal source picture in the push instruction according to the information (such as the signal source picture ID) of the signal source picture in the push instruction, the information of the signal source picture and the encoded video stream address reported by each push and display terminal before, and sends the target encoded video stream address and the push instruction to the corresponding target terminal according to the target terminal (assumed to be the push and display terminal 602) indicated in the push instruction. In the invention, sending the target coded video stream address and the push command to the corresponding target terminal comprises sending the target coded video stream address and the push command to the target terminal, or sending part of the target coded video stream address and the push command to the target terminal, for example, sending only the information of the display mode and the signal source picture in the target coded video stream address and the push command to the target terminal, or sending only the display mode in the target coded video stream address and the push command to the target terminal. The reported signal source picture information can be richer than the information of the signal source picture in the pushing instruction, so that only a small amount of signal source picture information, such as a signal source ID, is required to be reported in the later pushing process, other signal source picture information which is stored before and corresponds to the ID can be called, or the reported signal source picture information can be the same as the information of the signal source picture in the pushing instruction, or the signal source picture information in the pushing instruction can be richer than the information of the reported signal source picture, so that the flexibility of pushing each time is improved. The signal source picture information in the reported signal source picture information and the push instruction may include, for example, a signal source picture ID, a signal source picture definition, a signal source picture attribute, a signal source control protocol, a control ip and a port, a main and auxiliary code stream, whether a public network is opened, a public network code stream address, a signal source picture authority, or an authority of a push and display terminal where the signal source picture is located, and the like.
In the embodiment of the present invention, the signal source picture is an advertisement picture, the target terminal (push and display terminal 602) may directly receive the target encoded video stream address and the push command, obtain the corresponding encoded video stream according to the target encoded video stream address (for example, from the rtsp stream server of the push and display terminal 601), decode and display the decoded signal source picture according to the display mode indicated in the push command, and may additionally display other information of the signal source picture. If the signal source pictures to be pushed are pictures of two signal sources, the target terminal acquires each signal source picture according to the coded video stream address of each signal source picture to decode, and displays the decoded advertisement pictures according to the display mode indicated in the pushing instruction.
The push manner between the server and the target terminal is also intended to cover the following cases: the server sends a push command to the target terminal, the target terminal determines whether to receive the signal source picture according to the signal source picture information (such as the signal source ID) in the push command, after determining to receive the signal source picture, the server sends a confirmation command to the server, and the server sends the target coded video stream address to the target terminal.
According to some embodiments of the present invention, when the target terminal receives a request that the server prepares to send the target encoded video stream address and the push command to the target terminal, the target terminal may also jump out of a pop window first to prompt the user whether to receive the push, if the user selects the push command, the target terminal enters a display mode to receive the target encoded video stream address and the push command, obtain a corresponding encoded video stream according to the target encoded video stream address (e.g. from the rtsp stream server of the push and display terminal 601), decode the encoded video stream, and display the decoded signal source picture according to the display mode indicated in the push command.
According to some embodiments of the present invention, the target terminal may also determine whether to obtain a corresponding encoded video stream according to the target encoded video stream address (e.g. from an rtsp stream server of the push and display terminal 601) according to the signal source picture permission information in the information of the signal source picture pushed in the push instruction or the permission of the push and display terminal where the signal source picture is located (i.e. the push and display terminal pushing out the picture), and decode and display the decoded signal source picture according to the display mode indicated in the push instruction. Therefore, the push efficiency and the permission can be further and rapidly considered. The above case also covers that the target terminal compares the received rights with the rights of itself to determine whether to obtain the corresponding encoded video stream according to the target encoded video stream address (e.g. from the rtsp stream server of the push and display terminal 601), and decodes and displays the decoded signal source picture according to the display mode indicated in the push command.
The above scheme is also applicable to the case where the target terminal is the push and display terminal 601 itself. According to other embodiments of the present invention, the pushing and displaying terminal 601 may set a specific gesture for the pushing scenario, and when the pushing and displaying terminal 601 acquires the touch information corresponding to the specific gesture, the touch information is collected and analyzed, so that the gesture result of the specific gesture may be analyzed. The pushing and displaying terminal 601 sends the gesture result to the pushing instruction packaging module. The pushing instruction packaging module matches and collects pushing instructions, if the target terminal is determined to be the pushing and displaying terminal 601 according to the matched and collected pushing instructions, the pushing and displaying terminal 601 obtains a signal source picture according to the coded video stream address of the pushed signal source picture indicated in the pushing instructions, decodes the signal source picture and displays the signal source picture according to the display mode indicated in the pushing instructions. By the method, the push and display terminal can quickly display related signals when being used as a push end and a display end.
In the present invention, the status peer of the push and display terminal 601 and the push and display terminal 602 may have a function and a response manner of each other, and the description of the push and display terminal 601 is also applicable to the push and display terminal 602.
Through the embodiment of the invention, the display and the display mode of each signal source picture on each other terminal can be rapidly realized at each pushing and display terminal without an image centralized controller. In addition, the server only needs to transmit a small amount of pushing instructions in the whole pushing process, and signal source video streams at various places do not need to be forwarded or stored, so that the server load is low, and the problems of signal delay, large consumption of server resources and the like caused by the fact that the server participates in forwarding of a large amount of video streams are avoided. In addition, in the invention, because each signal source can be respectively positioned at a plurality of different terminals, unlike the control display technology of the image centralized controller in the prior art, the control display technology of the image centralized controller is different from the control display technology of the image centralized controller, all signal sources are required to be connected to the image centralized controller in a unified way, and then the pushing and the display of each signal source can be realized by controlling the image centralized controller, so that the problems of difficult connection and the like caused by the distance between the signal sources and the image centralized controller are also solved, and the invention does not have the problems. As will be further understood from the following description, the signal acquisition and encoding video streaming step and the step of reporting the server of the present invention occur prior to the push process independently of the subsequent push process, and when the actual push action occurs, the signal acquisition and encoding action does not need to be temporarily initiated, so that the problems of delayed push response and the like caused by performing encoding in response to push in the push process can be avoided.

According to some embodiments of the present invention, the rtsp video stream may also be sent to the push and display terminal by other signal sources through a network, and the latter stores the rtsp video stream on the rtsp stream server of the push and display terminal itself.
