Abstract

Systems and methods for executing multiple video games, or other sources of video, include a game execution environment in which each game application is executed on the same operating system but within a virtual I/O shell. The virtual I/O shell includes virtual video, audio and input channels that allow each game application to operate as if it had dedicated drivers. In some embodiments, the systems and methods of the invention are used to provide video streams to a plurality of clients over the internet.

Claims

1. A game delivery system comprising:

plurality of virtual I/O shells each configured to receive and redirect sound and video from a separate video game application;

a local manager configured to execute the separate video game applications on a shared operating system that is not virtualized, each of the separate video game applications being in one of the virtual I/O shells and accessing the shared operating system for non-I/O operations; and

a streaming server configured to stream video and audio from the separate video game applications, video and audio from each of the video game applications being streamed to a different client.

2. The game delivery system of claim 1, wherein the local manager is configured to simulate a virtual console using key mapping and inputs from a plurality of different clients, each having different IP addresses.

3. The game delivery system of claim 1, wherein the streaming server is configured to encode to a High Profile H.264 codec lacking B-frames.

4. The game delivery system of claim 1, wherein the streaming server is configured to switch between video codecs mid-stream while streaming the video.

5. The game delivery system of claim 4, wherein the switch between video codecs is responsive to a lag between the streaming server and one of the different clients.

6. The game delivery system of claim 1, wherein the streaming server is configured to switch to a lower quality codec in order to reduce lag between the streaming server and one of the different clients, when the lag reaches a threshold value.

7. The game delivery system of claim 1, wherein the streaming server is configured to deliver the video to multiple IP addresses.

8. The game delivery system of claim 7, wherein the presentation of the video at one of the IP addresses includes a link configured to allow a user to play the video game application.

9. The game delivery system of claim 7, wherein the presentation of the video at one of the IP addresses includes a link configured to allow a user to join another player in the video game application.

10. The game delivery system of claim 7, wherein the presentation of the video at one of the IP addresses includes a link configured to allow a user to interact in the video game application with another player.

11. The game delivery system of claim 1, wherein the local manager is configured to automatically spawn an additional video game application within a virtual I/O shell responsive to a request to play the video game application.

12. The game delivery system of claim 1, wherein each of the plurality of virtual I/O shells include a virtual sound channel driver configured to redirect sound received from the respective video game application and a virtual video channel driver configured to redirect video data received from the respective video game application.

13. The game delivery system of claim 12, further comprising memory configured to store the virtual sound channel driver and the virtual video channel driver;

and a microprocessor configured to execute the virtual sound channel driver and the virtual video channel driver.

14. The game delivery system of claim 1, wherein each of the virtual I/O shells does not prevent the respective video game application from directly accessing functions of the shared operating system.

15. The game delivery system of claim 1, wherein the plurality of virtual I/O shells is configured such that the shared operating system supports several separate video game applications, each of the separate video game applications operating within a different I/O shell.
