Abstract: A many-to-one transmission and information display method via local area network is implemented in a local area network comprising a first electronic device, at least one second electronic device, and at least one processing device connected to an output device to display information. In this method, a predetermined display information to be transmitted to the processing device is adjusted in advance based on a frame layout by the first electronic device and the second electronic device, respectively; then the adjusted predetermined display information is transmitted to the processing device to be integrated into the display information for the output device to display, thereby reducing the amount of data for transmission and the computation of integration process. A many-to-one transmission and information display system via local area network is also disclosed.

Abstract: A method of transmitting information from one to many terminals via wireless local area network (WLAN) is implemented in a WLAN including a first electronic device, and a plurality of second electronic devices. The method includes steps of: the first electronic device searching for the plurality of second electronic devices; the first electronic device designating one of the plurality of second electronic devices to be a primary receiving end; the first electronic device requesting the rest of the plurality of second electronic devices to change their channels to be the same as the channel of the primary receiving end; and the first electronic device transmitting information to the primary receiving end, and the rest of the second electronic devices intercepting the information and outputting the same. A system of transmitting information from one to many terminals via WLAN is also disclosed.

Abstract: A method for transmitting screen frames from one to many terminals is applied to a network system consisting of a first electronic device, a second electronic device, and a third electronic device. The method includes the following steps: the first electronic device transmitting a full screen frame and at least one rectangle data to the second electronic device via network packets, wherein the rectangle data is information of changed areas in the full screen frame; the second electronic device receiving the full screen frame and the rectangle data, and in accordance with each received network packet transmitting an acknowledgement; and the third electronic device intercepting the full screen frame and the rectangle data to reconstruct an updated screen frame for display. A system and a receiving device for transmitting screen frames from one to many terminals are disclosed simultaneously.

Abstract: A one-to-many transmission method and system to transmit real-time video and audio data on wireless local area network, which includes a first station, a second station, and at least one third station. The first station provides at least one video and audio program and a set-packet, and periodically transmits them to the second station. The second station transmits a command-packet to the first station to determine the content of video and audio program transmitted by the first station, and receives the set-packet to confirm whether the set-packet is correct or not. The third station intercepts and receives the set-packet, and according to the configuration of the set-packet changes its network configuration to receive the video and audio program transmitted by the first station, and selectively play the content.

Abstract: A method for improving transmission efficiency of wireless local area network (WLAN) comprises a WLAN neighbors establishing procedure and a high efficiency transmission mode establishing procedure. The WLAN neighbors establishing procedure establishes neighbors between stations of the WLAN. The high efficiency transmission mode establishing procedure causes the stations to disassociate with the access point in a power save mode and switch from an infrastructure mode to an ad-hoc mode for transmitting data. The present invention also discloses a corresponding system of improving transmission efficiency of WLAN.
