Audio, video and control system implementing virtual machines
The system of the present technology includes an embodiment that provides a host audio, video and control operating system configured to establish or interact with one or more virtual machines, each with a guest operating system.
1. A method comprising:
implementing, by a host audio, video, control (AVC) operating system (OS), a virtual machine with a guest OS different from the host AVC OS;
establishing a virtual hardware connection between the host AVC OS and the guest OS;
receiving an AVC signal at the host AVC OS;
processing the AVC signal at the host AVC OS; and
routing the processed AVC signal through the virtual hardware connection to the guest OS.
2. The method of claim 1 further comprising:
receiving a second AVC signal at the guest OS;
routing the second AVC signal through the virtual hardware connection to the host AVC OS;
processing the second AVC signal at the host AVC OS; and
routing the processed second AVC signal to a destination external to a computing device executing the host AVC OS.
3. The method of claim 1 wherein processing the AVC signal comprises gain and level adjustments, echo reduction, mixing, color or resolution adjustments, cropping, delay control, or any combination thereof.
4. The method of claim 1 wherein the host AVC OS is a real-time OS.
5. The method of claim 1 wherein the host AVC OS is an x86 framework compatible OS.
6. The method of claim 1 wherein the guest OS is a Windows-based OS, a Chrome-based OS, a Mac-based OS, or a Linux-based OS.
7. The method of claim 1 wherein the virtual hardware connection is a virtual USB connection.
8. The method of claim 7 wherein establishing the virtual USB connection comprises generating a virtual USB device board and presenting it to the virtual machine as an available hardware component.
9. The method of claim 7 wherein establishing the virtual hardware connection includes creating an isochronous connection between the host AVC OS and the virtual USB connection, wherein the isochronous connection provides time-dependent data transfer at a steady rate.
10. The method of claim 9 wherein routing the processed AVC signal to the guest OS includes providing the processed AVC signal as input to the isochronous connection.
11. The method of claim 1 wherein implementing the virtual machine comprises creating a virtual machine environment and installing the guest OS into the virtual machine environment.
12. The method of claim 1 wherein implementing the virtual machine comprises loading a virtual machine image previously created with the guest OS already installed.
13. A system comprising:
one or more processors;
a memory; and
a real-time operating system (OS) configured to:
implement a virtual machine with a guest OS;
establish a virtual hardware connection between the real-time OS and the guest OS;
receive and process an AVC signal; and
route the processed AVC signal through the virtual hardware connection to the guest OS.
14. The system of claim 13 further comprising at least two CPUs, wherein at least a first of the at least two CPUs is dedicated to the real-time OS and at least a second of the at least two CPUs is dedicated to the guest OS.
15. The system of claim 13 further comprising at least two network cards, wherein at least a first of the at least two network cards is dedicated to the real-time OS and at least a second of the at least two network cards is dedicated to the guest OS.
16. The system of claim 13 wherein establishing the virtual hardware connection includes creating an isochronous connection between the real-time OS and a virtual USB connection, wherein the isochronous connection provides time-dependent data transfer at a steady rate.
17. A computer-readable storage medium storing instructions that, when executed by a computing system, cause the computing system to perform operations comprising:
implementing, by a host audio, video, control (AVC) operating system (OS), a virtual machine with a guest OS different from the host AVC OS;
establishing a virtual hardware connection between the host AVC OS and the guest OS;
receiving an AVC signal at the host AVC OS;
processing the AVC signal at the host AVC OS; and
routing the processed AVC signal through the virtual hardware connection to the guest OS.
18. The computer-readable storage medium of claim 17 , wherein the operations further comprise:
receiving a second AVC signal at the guest OS;
routing the second AVC signal through the virtual hardware connection to the host AVC OS; and
processing the second AVC signal at the host AVC OS.
19. The computer-readable storage medium of claim 17 wherein the host AVC OS is an x86 framework compatible OS.
20. The computer-readable storage medium of claim 17 wherein the virtual hardware connection is a virtual USB connection.
