Patent ID: 8911291

Claim:
A display system for a video wall, comprising: at least one server, wherein each said server renders an image, encrypts the image, and transmits the image to a network; and a plurality of player devices coupled to the at least one server through the network, wherein each said player device receives the image or a part of the image rendered by one of the at least one server from the network, decrypts the image or the part of the image, and determines a synchronization time together with at least one of the other player devices, and each said player device respectively uses a display of the video wall to simultaneously display the image or the part of the image at the synchronization time, wherein each said server comprises: a memory; a graphics processing unit coupled to the memory, rendering the image and storing the image into the memory; a central processing unit coupled to the memory, encrypting the image rendered by the graphics processing unit; and a first network unit coupled between the central processing unit and the network, and transmitting the encrypted image to the network; and each said player device comprises: a second network unit coupled to the at least one server through the network, and receiving the image or the part of the image from the network; a synchronization unit coupled to the second network unit, and determining the synchronization time together with a synchronization unit of the at least one of the other player devices through the second network unit; a decoding unit coupled to the second network unit, decrypting the image or the part of the image received by the second network unit; and a display unit coupled to the decoding unit and the synchronization unit, and using the display of the video wall to display the decrypted image or the decrypted part of the image at the synchronization time.
