Abstract: A display method and a display system for a video wall are proposed. The method is applicable to a display system having a server and multiple player devices. Each of the player devices is connected to the server and a video wall having multiple displays, and each of the player devices corresponds to a different one of the displays and a different one of regions in a video stream. The method includes to receive the video stream from the server by each of the player devices, to send a broadcast command by a master player device among the player devices to other player devices, and to start displaying the corresponding region in a first frame of the video stream on the corresponding display of the video wall by each of the player devices after a preset delay time interval according to the broadcast command.

Abstract: The present invention provides a video conference system. The video conference system includes a plurality of terminal equipment and a server. Each of the terminal equipment estimates and transmits real-time bandwidth and conference requirements to the server. A multipoint control unit of the server includes a multipoint controller and a multipoint processor. The multipoint controller determines, according to the real-time bandwidth and the conference requirements, a transfer rule and an allocation scheme corresponding to each of the terminal equipment. The multipoint processor receives the transfer rule and voice data stream or video data stream from the terminal equipment. The server transmits each of the allocation schemes to the corresponding terminal equipment. When any of the terminal equipment transmits new real-time bandwidth or new conference requirements to the server, the multipoint controller determines the transfer rule and the allocation schemes once again.

Abstract: A display system and a display method for video walls are provided. The display system includes at least one server and a plurality of player devices. Each server renders an image and transmits the image to a network. The player devices are coupled to the at least one server through the network. Each player device receives the image or a part of the image rendered by one of the at least one server, and determines a synchronization time together with at least one of the other player devices. Each player device uses a display of a video wall to simultaneously display the image or the part of the image at the synchronization time.
