SYSTEM AND METHOD FOR FORWARDING A GRAPHICS COMMAND STREAM
A system and method for forwarding a graphics command stream. A graphics renderer may receive a graphics command stream where the graphic command stream contains graphical information renderable as a graphical image. The graphics renderer may process the received graphics command stream to generate a processed graphics stream where the processed graphics stream contains equivalent graphical information to the graphical information contained in the graphics command stream. A source redirector may encode the processed graphics stream to generate a formatted graphics stream. A source protocol stack may send the formatted graphics stream to a target graphics component. A target redirector may receive and decode the formatted graphics stream. The target redirector may process the decoded formatted graphics stream to generate a target graphics command stream where the target command stream contains equivalent graphical information contained in the formatted graphics stream.
1 . A method for forwarding a graphics command stream comprising:
receiving a source graphics command stream, encoded for rendering by a source graphics component using a source graphics semantic, where the source graphic command stream contains graphical information renderable as a graphical image;
processing the received source graphics command stream to generate a processed graphics stream where the processed graphics stream contains equivalent graphical information to the graphical information contained in the source graphics command stream;
encoding the processed graphics stream to generate a source formatted graphics stream; and
sending the source formatted graphics stream to a target graphics component where the source formatted graphics stream is convertible to a target graphics semantic renderable as a graphical image by the target graphics component.
2 . The method for forwarding a graphics command stream of claim 1 , where each of the source graphics semantic and the target graphics semantic is based on any of: OPENGL, OPENGL ES, OPENCL, and OPENVG.
3 . The method for forwarding a graphics command stream of claim 1 , where the source graphics semantic and the target graphics semantic are different.
4 . The method for forwarding a graphics command stream of claim 1 , where the graphical information may include any of: a command, a response and data.
5 . The method for forwarding a graphics command stream of claim 1 , where the graphical information is cached.
6 . The method for forwarding a graphics command stream of claim 1 , where the act of processing the received source graphics command stream to generate a processed graphics stream reduces the amount of the graphical information.
7 . The method for forwarding a graphics command stream of claim 6 , where the act of processing that reduces the amount of graphical information may include any one or more of: applying data compression to the graphical information, returning a cached response and transmitting a code associated with cached graphical information in place of the graphical information.
8 . The method for forwarding a graphics command stream of claim 1 , where the source formatted graphics stream includes graphical information and metadata.
9 . The method for forwarding a graphics command stream of claim 8 , where the metadata includes any one or more of: initialization instructions, synchronization information, timing information, error correction codes and retransmission requests.
10 . The method for forwarding a graphics command stream of claim 1 , where the source formatted graphics stream is sent to the target graphics component using a wired or a wireless network.
11 . The method for forwarding a graphics command stream of claim 1 , where the source formatted graphics stream is sent to the target graphics component using a transmission control protocol or a user datagram protocol.
12 . The method for forwarding a graphics command stream of claim 1 , where the source formatted graphics stream is sent to one or more target graphics components.
13 . A system for forwarding a graphics command stream comprising:
a source graphics renderer to:
receive a source graphics command stream, encoded for rendering by a source graphics component using a source graphics semantic, where the source graphic command stream contains graphical information renderable as a graphical image; and
process the received source graphics command stream to generate a processed graphics stream where the processed graphics stream contains equivalent graphical information to the graphical information contained in the source graphics command stream;
a source redirector to encode the processed graphics stream to generate a source formatted graphics stream; and
a source protocol stack to send the source formatted graphics stream to a target graphics component where the source formatted graphics stream is convertible to a target graphics semantic renderable as a graphical image by the target graphics component.
14 . The system for forwarding a graphics command stream of claim 13 , where each of the source graphics semantic and the target graphics semantic is based on any of: OPENGL, OPENGL ES, OPENCL, and OPENVG.
15 . The system for forwarding a graphics command stream of claim 13 , where the source graphics semantic and the target graphics semantic are different.
16 . The system for forwarding a graphics command stream of claim 13 , where the graphical information may include any of: a command, a response and data.
17 . The system for forwarding a graphics command stream of claim 13 , where the graphical information is cached.
18 . The system for forwarding a graphics command stream of claim 13 , where processing the received source graphics command stream to generate a processed graphics stream reduces the amount of the graphical information.
19 . The system for forwarding a graphics command stream of claim 18 , where the processing that reduces the amount of graphical information may include any one or more of: applying data compression to the graphical information, returning a cached response and transmitting a code associated with cached graphical information in place of the graphical information.
20 . The system for forwarding a graphics command stream of claim 13 , where the source formatted graphics stream includes graphical information and metadata.
21 . The system for forwarding a graphics command stream of claim 20 , where the metadata includes any one or more of: initialization instructions, synchronization information, timing information, error correction codes and retransmission requests.
22 . The system for forwarding a graphics command stream of claim 13 , where the source formatted graphics stream is sent to the target graphics component using a wired or a wireless network.
23 . The system for forwarding a graphics command stream of claim 13 , where the source formatted graphics stream is sent to the target graphics component using a transmission control protocol or a user datagram protocol.
24 . The system for forwarding a graphics command stream of claim 13 , where the source formatted graphics stream is sent to one or more target graphics components.
