Visual messaging system for high speed networks
First Claim
1. A visual messaging device for displaying messages in response to data constituting said messages transmitted by a remote system over a high speed network at a predetermined network data rate constituting a certain bandwidth of the network, said visual messaging device comprising:
- a visual display device having a plurality of individual light emitting diodes adapted to display said messages;
a shared memory having a first and second segments for respectively storing data transmitted by the remote system and messages processed by a processor at network data rate;
a network interface within said visual messaging device receiving said data transmitted by the remote system and storing such received data in packets in the first segment of the shared memory at said network data rate without reducing the bandwidth of the high speed network;
a processor within said visual messaging device, said processor retrieving the data packets from the first segment of the shared memory, processing the retrieved packets according to one or more programs associated with the processor to build bit maps for display on said visual display device, and storing the bit maps in the second segment of the shared memory in order at the network data rate, thereby enabling the visual messaging device to receive, process and display on the visual display device messages transmitted by the remote system in real time; and
a display driver retrieving said bit maps from the second segment of the shared memory in said select order, said display driver in response to said bit maps activating and deactivating said individual light emitting diodes to display said messages on said visual display unit.

Abstract
The present invention provides a visual messaging device for use with a high speed network. The message data is communicated to the network by a remote device, such as a computer or server. The visual messaging device includes a network interface circuit that receives the message data from the network and arranges it in a memory unit in usable form (packets) for use by a processor at the high network speed. The processor includes a central processing unit (CPU) and is a multi-tasking device, which sequences the messages in real time for display by the display device according to programmed instructions stored or provided to the visual messaging device. A display driver activates and deactivates the visual elements, such as individual LEDs, according to the processor'"'"'s instructions. The various elements of the visual messaging device communicate in real time over a common data bus. The network may be a local area network, wide area network or the internet. A first memory stores the available messages from the receiver in a selected format for use by said processor and a second memory stores programs or programmed instructions. A common data bus provides two-way communications means for the processor, memories, network interface and the display driver. The processor provides status reports of the messages to the remote unit at the network speed.
