As further shown in fig. 5C, the notification of one of the transmission ends can be performed by at least one of a hover gesture control and a voice control by a user of the transmission end of the notification.

FIGS. 6A-6B are flow charts illustrating a method for wireless transmission using the message light display of the receiving device of the receiving end of the wireless audiovisual transmission system according to the present invention. As shown in fig. 6A to 6B, the wireless audio/video transmission system and method may further include that after the receiving device 3 of the receiving end receives the guest setting 140 of the specific transmitting device 2a, the message lamp of the receiving device 3 of the receiving end displays a first indication; and after the receiving device 3 of the receiving end receives the visitors release 150 of the specific transmission device 2a, the message lamp of the receiving device 3 of the receiving end displays a second indication. The states of the first indication and the second indication displayed by the message lamp to indicate the transmitting device 2, 2a of the transmitting end and the receiving device 3 of the receiving end can be illustrated in fig. 6A to 6B.

fig. 6A to 6B illustrate the operation flows of the receiving apparatus 3 on the receiving side and the transmitting apparatuses 2 and 2a on the transmitting side, respectively. In fig. 6A to 6B, the receiving device 3 at the receiving end and the transmitting devices 2 and 2a at the transmitting end respectively have different information lamp display modes to show the respective states, and the user can operate and control the specific transmitting device 2a in at least one of the floating gestures 5 and 6 and the voice control to generate the guest setting 140/guest release 150, and can sense the floating gesture 5 and 6 control and/or the voice control of the user to start/stop (start/stop), pause/resume (pause/resume), menu (menu), end menu (exit menu) and the like for the transmitting devices 2 and 2 a. For example, the video signal of the transmission device 2, 2a at the transmission end is output to the display device 4 in a projection manner.

As shown in fig. 6A, the receiving device 3 at the receiving end first checks that the connection of the transmitting device 2, 2a at the transmitting end is started and waited for by the user in at least one of the way of hover gesture control and voice control. The receiver checks whether the guest setting 140 of a specific transmission device 2a is received to perform the projection of the specific transmission device 2 a. Or prepare to receive the notification from one of the transmission devices 2 at least one transmission end (the user performs the operation projection by at least one of the floating gestures 5, 6 and voice control) to perform the projection of the transmission device 2, 2a at the transmission end of the notification.

As shown in fig. 6B, the transmitting device 2, 2a at the transmitting end first checks the power-on (the user operates in at least one of the ways of hover gesture 5, 6 control and voice control) and the smooth connection with the receiving end. Then, the guest setting 140 of a specific transmission device 2a is checked, and the projection of the specific transmission device 2a is performed. And checking whether there is a guest release 150 of a specific transmission device 2a to perform projection of the transmission device 2 of the other transmission side.

When the wireless video transmission system is used for carrying out the wireless video transmission method, firstly, a starting action is carried out, each transmission device at least one transmission end is confirmed to be connected with a receiving device at a receiving end so as to carry out video signal transmission, wherein the video signals are compressed and encoded package video signals; then, an operation action is carried out, and a user can operate and control each transmission device of the at least one transmission end in at least one mode of suspension gesture control and sound control, so that the operation of the transmission device and/or the setting/releasing of the honored guest can be carried out; then, a display operation is performed, the receiving device at the receiving end can receive the video signal output by each transmission device from the at least one transmission end in a wireless manner, wherein if the receiving device at the receiving end receives the guest setting of a transmission device at a specific transmission end of the at least one transmission end, the video signal output by the transmission device at the specific transmission end is decompressed preferentially, the decompressed video signal is preferentially output to a display device and displayed on the display device until the receiving device at the receiving end receives the release of the guest of the transmission device at the specific transmission end of the at least one transmission end, if any guest setting is not received, the receiving device at the receiving end decompresses the video signal according to the priority of the received video signal from at least one of the at least one transmission end, and the decompressed video and audio signal is outputted to the display device for displaying.

Furthermore, the wireless audio-video transmission method also comprises the step that the receiving end receives the setting of the honored guest of the specific transmission end, and the receiving end message lamp displays a first indication; and the receiving end receives the release of the honoured guest of the specific transmission end, and the receiving end message lamp displays a second indication.

Further, the video signal is audio, picture or video program.

The disclosed technology provides a wireless audio/video transmission system and method, and the technical design includes a VIP anti-robbing mechanism for setting and releasing the VIP to adjust the display sequence and order of the audio/video signals of the transmission device at the transmission end.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention; it is intended that all such equivalent changes and modifications be included within the scope of the present disclosure, which is not to be considered as within the scope of the present disclosure.
