Data flow manager for device mobility
View Patent ↗A system and method for transferring data flows, such as streaming video or audio signals, between end devices that are members of the same end device group is provided. A network examining module identifies end devices having an active data flow. A data session populating module populates a data store for an end device group identifying end devices having active data flows. A managing module determines which end devices are compatible for a data flow to be transferred. The data flow transferring module transfers the active data flow from one group member end device to another group member end device.
1. One or more tangible computer-readable media having computer-useable instructions embodied thereon for performing a method for transferring a streaming video signal being viewed via a second end device from the second end device to a first end device, the method comprising:
receiving at a data flow manager operating at a computing device, a request from a first end device to transfer a streaming video signal being viewed via a second end device such that the streaming video signal is viewed via the first end device, wherein the first and second end devices are part of a user-designated end device group, and wherein the computing device is separate and distinct from the first end device and the second end device;
determining whether the first end device and second end device are compatible;
transferring the steaming video signal from being viewed via the second end device to being viewed via the first end device if the first and second end devices are compatible, and
terminating the streaming of the video signal to the second end device such that the video signal is no longer viewable via the second end device; or
continuing the streaming of the video signal to the second end device such that the video signal streams to both the first end device and the second end device substantially simultaneously.
2. The computer-readable media of claim 1 , wherein the first and second end devices are one of a cellular phone, a telephone, a home computer, a set-top box, personal data assistant and a digital video recorder.
3. The computer-readable media of claim 1 , wherein the streaming video signal is a codec signal.
4. The computer-readable media of claim 1 , wherein the first and second end devices are compatible if the first end device can support the streaming video signal of the second end device.
5. One or more tangible computer-readable media having computer-useable instructions embodied thereon for performing a method for transferring a streaming video signal being viewed via a first end device from the first end device to a second end device, the method comprising:
receiving at a data flow manager operating at a computing device, a request from a first end device to transfer a streaming video signal being viewed via the first end device such that the streaming video signal is viewed via a second end device, wherein the first and second end devices are part of a user-designated end device group, and wherein the computing device is separate and distinct from the first end device and the second end device;
determining whether the first end device and second end device are compatible; and
when the first and second end devices are compatible, transferring the steaming video signal from being viewed via the first end device to being viewed via the second end device; or
continuing the streaming of the video signal to the first end device such that the video signal streams to both the first end device and the second end device substantially simultaneously.
6. The computer-readable media of claim 5 , wherein the first and second end devices are one of a cellular phone, a telephone, a home computer, a set-top box, personal data assistant and a digital video recorder.
7. The computer-readable media of claim 5 , wherein the streaming video signal is a codec signal.
8. The computer-readable media of claim 5 , wherein the first and second end devices are compatible if the second end device can support the streaming video signal of the first end device.
9. One or more tangible computer-readable media having computer-useable instructions embodied thereon for performing a method for transferring a streaming video signal being viewed via a second end device from the second end device to a first end device, the method comprising:
a data flow manager operating at a computing device monitoring a network for one or more active data flows;
the data flow manager identifying an active data flow from a second end device and determining one or more attributes of the active data flow, wherein the active data flow is a streaming video signal;
determining that the second end device is a member of a user-designated end device group;
receiving at the data flow manager, a request from a first end device to transfer the streaming video signal being viewed via the second end device such that the streaming video signal is viewed via the first end device, wherein the first and second end devices are one or more of a cellular phone, a telephone, a home computer, a set-top box, personal data assistant and a digital video recorder, and wherein the first end device is part of the user-designated end device group;
determining whether the first end device and second end device are compatible, wherein the first and second end devices are compatible if the first end device can support the streaming video signal being viewed via the second end device; and
transferring the steaming video signal from being viewed via the second end device to being viewed via the first end device if the first and second end devices are compatible, and
a) terminating the streaming of the video signal to the second end device such that the streaming video signal is no longer viewable via the second end device, or
b) continuing to stream the video signal to the second end device while the streaming video signal is also being sent to the first end device such that the video signal is being viewed via both the first and second end devices,
wherein the computing device at which the data flow manager operates is separate and distinct from the first end device and the second end device.
10. The computer-readable media of claim 9 , wherein the streaming video signal is a codec signal.
11. The computer-readable media of claim 1 , wherein the streaming video signal includes both content packets and signal packets, and wherein a signal packet includes data attributes for the streaming video signal.
12. The computer-readable media of claim 5 , wherein the streaming video signal includes both content packets and signal packets, and wherein a signal packet includes data attributes for the streaming video signal.
13. The computer-readable media of claim 9 , wherein the streaming video signal includes both content packets and signal packets, and wherein a signal packet includes data attributes for the streaming video signal.
14. The computer-readable media of claim 4 , wherein the streaming video signal is transcoded to allow the first end device to support the streaming video signal.
15. The computer-readable media of claim 8 , wherein the streaming video signal is transcoded to allow the second end device to support the streaming video signal.
16. The computer-readable media of claim 9 , wherein the streaming video signal is transcoded to allow the first end device to support the streaming video signal.
17. The computer-readable media of claim 9 , wherein the streaming of the video signal to the second end device is terminated when the request is a “pull” request, and the streaming of the video signal to the second end device is continued when the request is a “join” request.
