Method and system for communicating between a host device and a user device through an intermediate device using a composite graphics signal

摘要

A system and method includes a host device, an intermediate device and a user device. A network is in communication with the host device, the intermediate device and the user device. The host device communicates a first graphics command and a second graphics command to the intermediate device. The intermediate device composites the first graphics command and the second graphics command to form a composite graphics command and communicating the composite graphics command to the user device. The user device generates a screen display in response to the composite graphics command.

1. A system comprising:
a host device that is directly connected to a network; an intermediate device, separate from the host device, having a first buffer, a second buffer and a third buffer and being indirectly connected to the network via the host device; and a user device, separate from the intermediate device and the host device, indirectly connected to the network via the intermediate device; said host device communicating a first graphics command and a second graphics command to the intermediate device; said intermediate device storing the first graphics command in a first buffer and the second graphics command in a second buffer, said intermediate device compositing the first graphics command from the first buffer and the second graphics command of the second buffer by blending the first graphics command and the second graphics command to form a composite graphics command in a third buffer, and communicating the composite graphics command from the third buffer to the user device; said user device generating a screen display in response to the composite graphics command, generating a first response signal in response to the composite graphics command and communicating the first response signal to the intermediate device; said intermediate device mapping the first response signal with the first graphics command and the second graphics command, generating a second response signal in response thereto and communicating the second response signal to the host device.
