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 operating system (OS), a virtual machine with a guest audio, video, control (AVC) OS different from the host OS;
establishing a virtual hardware connection between the host OS and the guest AVC OS;
receiving an AVC signal at the guest AVC OS;
processing the AVC signal at the guest AVC OS; and
routing the processed AVC signal through the virtual hardware connection to the host OS.
2. The method of claim 1 wherein the AVC signal is a first signal, and wherein the method further comprises:
receiving a second AVC signal at the host OS;
routing the second AVC signal through the virtual hardware connection to the guest AVC OS;
processing the second AVC signal at the guest AVC OS; and
routing the processed second AVC signal to a destination external to a computing device executing the host 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 guest AVC OS is a real-time OS.
5. The method of claim 1 wherein the guest OS is an x86 framework compatible OS.
6. The method of claim 1 , further comprising establishing a second virtual hardware connection between the guest AVC OS and a network interface card.
7. The method of claim 1 wherein the virtual hardware connection is a virtual ethernet switch connection.
8. The method of claim 7 wherein establishing the virtual ethernet switch connection comprises generating a virtual ethernet switch 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 guest AVC OS and the virtual ethernet switch 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 host 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 AVC OS already installed.
13. A system comprising:
one or more processors;
a memory; and
a host operating system (OS) configured to:
implement a virtual machine with a guest real-time OS; and
establish a virtual hardware connection between the host OS and the real-time guest OS, wherein the guest real-time OS is configured to:
receive and process an AVC signal; and
route the processed AVC signal through the virtual hardware connection to the host 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 host OS and at least a second of the at least two CPUs is dedicated to the guest real-time 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 host OS and at least a second of the at least two network cards is dedicated to the real-time guest OS.
16. The system of claim 15 wherein implementing the virtual machine with the guest real-time OS includes establishing a virtual hardware connection between the guest real-time OS and the second network card.
17. The system of claim 13 wherein establishing the virtual hardware connection includes creating an isochronous connection between the guest real-time OS and a virtual ethernet switch, wherein the isochronous connection provides time-dependent data transfer at a steady rate.
18. A non-transitory 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 operating system (OS), a virtual machine with a guest audio, video, control (AVC) OS different from the host OS;
establishing a virtual hardware connection between the host OS and the guest AVC OS;
receiving an AVC signal at the guest AVC OS;
processing the AVC signal at the guest AVC OS; and
routing the processed AVC signal through the virtual hardware connection to the host OS.
19. The non-transitory computer-readable storage medium of claim 18 , wherein the operations further comprise:
receiving a second AVC signal at the host OS;
routing the second AVC signal through the virtual hardware connection to the guest AVC OS; and
processing the second AVC signal at the guest AVC OS.
20. The non-transitory computer-readable storage medium of claim 17 wherein the virtual hardware connection is through a virtual ethernet switch.
