Method and apparatus for secure transfer and playback of multimedia content
A method and apparatus for secure transfer and playback of multimedia content enables the secure transfer of multimedia content from a digital video recorder (DVR) to a personal computer (PC) and further to a handheld device. A DVR determines which devices on a Local Area Network (LAN) are authorized to share and/or retrieve content from the DVR. The DVR receives a connection request from a PC on the LAN, authorizes the connection request and establishes a secure connection between the DVR and the PC. Once the secure connection is established, the DVR receives a request for multimedia content from the PC, prepares the multimedia content for transfer and transfers the multimedia content to the PC.
1. A method comprising:
transmitting, from a first device to a second device, over a network, a first request to view an item of multimedia content;
receiving, at the first device from the second device, a message instructing the first device to request the item of multimedia content from a third device;
in response to receiving the message, transmitting, from the first device to the third device, over the network, a second request for the item of multimedia content; and
receiving, at the first device from the third device, the item of multimedia content in response to the second request.
2. The method of claim 1 , wherein the third device is a digital video recorder.
3. The method of claim 1 , wherein the item of multimedia content is content recorded or downloaded by the third device.
4. The method of claim 1 , wherein the first device is a portable device configured to receive the item over a local area network and/or wireless interface.
5. The method of claim 1 , further comprising, prior to the second device receiving the first request, receiving, by the first device, from the second device, a listing of content accessible at the third device.
6. The method of claim 1 , further comprising:
receiving, by the second device, key information from the first device;
using, by the second device, the key information to establish a connection with the third device.
7. The method of claim 1 , wherein the second device is a personal computing device.
8. The method of claim 1 , further comprising transcoding, at the third device, the item of multimedia content into a format suitable for playback on the first device.
9. One or more non-transitory computer-readable media storing instructions that, when executed by one or more computing devices, cause performance of:
transmitting, from a first device to a second device, over a network, a first request to view an item of multimedia content;
receiving, at the first device from the second device, a message instructing the first device to request the item of multimedia content from a third device;
in response to receiving the message, transmitting, from the first device to the third device, over the network, a second request for the item of multimedia content; and
receiving, at the first device from the third device, the item of multimedia content in response to the second request.
10. The one or more non-transitory computer-readable media of claim 9 , wherein the third device is a digital video recorder.
11. The one or more non-transitory computer-readable media of claim 9 , wherein the item of multimedia content is content recorded or downloaded by the third device.
12. The one or more non-transitory computer-readable media of claim 9 , wherein the first device is a portable device configured to receive the item over a local area network and/or wireless interface.
13. The one or more non-transitory computer-readable media of claim 9 , wherein the instructions, when executed by the one or more computing devices, further cause performance of, prior to the first device receiving the message, receiving, by the first device, from the second device, a listing of content accessible at the third device.
14. The one or more non-transitory computer-readable media of claim 9 , wherein the instructions, when executed by the one or more computing devices, further cause performance of:
receiving, by the second device, key information from the first device;
using, by the second device, the key information to establish a connection with the third device.
15. The one or more non-transitory computer-readable media of claim 9 , wherein the second device is a personal computing device.
16. The one or more non-transitory computer-readable media of claim 9 , wherein the instructions, when executed by the one or more computing device, further cause performance of transcoding, at the third device, the item of multimedia content into a format suitable for playback on the first device.
