Abstract
An accelerated secondary display system comprising a display adapter with a display simulator, a host computer with host software, a client device with a screen and client software. The display simulator is configured to send display characteristics to the host computer. The host computer is configured to receive the display characteristics and render an image into a frame buffer. The host software is configured to cause the host computer to stream image data over a communication channel, the image data based on the image in the frame buffer. The client software is configured to receive the image data over the communication channel and present a copy of the image on the screen based on the image data.
Claims20
An accelerated secondary display system comprising:
- a display adapter with a display simulator configured to transmit display characteristics;
- a host computer with a host computer memory storing host software, the host computer separate from the display adapter and configured to connect with the display adapter, the host computer configured to receive the display characteristics, instantiate a frame buffer in the host computer memory, render an image into the frame buffer, maintain pixels of the image in the frame buffer, and execute the host software, wherein the host software is configured to cause the host computer to stream image data over a communication channel, the image data based on the pixels of the image in the frame buffer, wherein the host software is configured to work with a host computer operating system that is not specially modified to work with the display adapter and host software;
- wherein the display simulator is configured to convince the host computer that a display is connected to the host computer by transmitting the display characteristics to the host computer;
- and
- a client device with a screen and a client device memory storing client software, the client device separate from the display adapter and the host computer, wherein the client software is configured to, when executed, receive the image data over the communication channel and present a copy of the image on the screen based on the image data.
