Abstract

A camera capable of transmitting image data to devices on a network is disclosed.

Claims

13. A system comprising:

a camera, said camera comprising a communication adapter adapted for connecting to a data transmission network and logic adapted to receive information from said data communication network addressed according to a network address associated with said camera; and

a media device capable of being adapted for connecting to said data transmission network and comprising logic to associate to discover said camera on said network,

wherein said camera is discoverable by said media device according to said network address in response to at least one of a connection of said camera to said data communication network and/or connection of said media device to said data transmission network.

14. The system of claim 13, wherein said camera further comprises logic to broadcast said network address to one or more devices in response to connection of said camera to said data communication network, and wherein said media device is capable of discovering said camera based, at least in part, on said broadcasted network address.

15. The system of claim 14, wherein said camera further comprises logic to broadcast information descriptive of one or more functional abilities of said camera to one or more device in response to said connection of said camera to said data network, and wherein said media device is capable of discovering said camera based, at least in part, on said broadcasted information descriptive of said one or more functional abilities.

16. The system of claim 13, wherein said camera comprises logic to provide said network address to said media device in response to a poll signal from said media device.

17. The system of claim 13, wherein said camera comprises logic to transit one or messages comprising information descriptive of at least one functional ability of said camera to said media device in response to a poll signal from said media device.

18. The system of claim 13, wherein said media device comprises logic to poll devices on said data transmission network in response to connection of said media device to said network, and wherein said camera further comprises logic to transmit said network address to said media device in response to said poll.

19. The system of claim 13, wherein said media device is capable of rendering images on a display in response to content data, and wherein said media device is capable of rendering a menu on said display including information identifying said camera in response to discovery of said camera by said media device.

20. An article comprising:

a storage medium comprising machine-readable instructions stored thereon to;

obtain a network address associated with a camera in response to connection of said camera to a data transmission network;

enable discovery of said camera by one or more other devices connected to said data transmission network based, at least in part, on said network address; and

stream image data captured at said camera to at least one of said one or more other devices in response to receipt of at least one message addressed according to said network address.

1. A camera comprising:

a communication adapter to transmit information to and/or receive information from a data communication network;

an imager to capture images; and

circuitry to generate content data based, at least in part, on said captured images,

wherein said camera is discoverable on said data communication network according to a network address associated with said camera.

2. The camera of claim 1, wherein said data communication network comprises a local network and wherein said camera is discoverable according to a network discovery protocol.

3. The camera of claim 1, wherein said camera is discoverable according to an SDDP protocol.

4. The camera of claim 1, wherein said network address comprises an Internet Protocol (IP) address.

5. The camera of claim 4, wherein said camera is adapted to obtain said IP address according to a DHCP protocol.

6. The camera of claim 1, wherein said camera is further adapted to transmit said content data to one or more client devices in responses messages addressed according to said discovered network address.

7. The camera of claim 6, wherein said server is capable of transmitting said content data to said one or more client devices in packets addressed to said one or more client devices according to one or more IP addresses associated with said one or more client devices.

8. The camera of claim 1, and further comprising:

readout circuitry to transfer signals representative of said captured images from said imager; and

an encoder to process said transferred signals to provide said stored content data.

9. The camera of claim 8, wherein said encoder is capable of encoding said content data in a substantially MPEG compliant format.

10. The camera of claim 1, wherein said camera is adapted to host a substantially UPnP AV compliant MediaServer associated with said network address.

11. The camera of claim 10, wherein said substantially UPnP AV compliant MediaServer is capable of transmitting said content data to one or more client devices in response to one or more messages from one or more substantially UPnP compliant Control Points.

12. The camera of claim 10, wherein said one or more client devices comprise one or more substantially UPnP AV compliant MediaRenderers.

21. The article of claim 20, wherein said storage medium further comprises machine-readable instructions stored thereon to broadcast said network address to said one or more other devices.

22. The article of claim 21, wherein said storage medium further comprises machine-readable instructions stored thereon to broadcast information descriptive of one or more functional abilities associated with said camera to said one or more other devices.

23. The article of claim 20, wherein said storage medium further comprises machine-readable instructions stored thereon to transmit said network address to at least one of said one or more other devices in response to a poll message from said at least one of said one or more other devices.

24. The article of claim 20, wherein said storage medium further comprises machine-readable instructions stored thereon to control said camera in response to one or more messages addressed according to said network address.

25. The article of claim 24, wherein said storage medium further comprises machine-readable instructions stored thereon to adjustably control one or more of zoom, tilt, focus and/or pan of said camera in response to said one or more messages.

26. The article of claim 24, wherein said storage medium further comprises machine-readable instructions stored thereon to said camera to perform one or more functions in response to said one or messages.

27. The article of claim 26, wherein said one or more functions comprises taking a snapshot.

28. The article of claim 26, wherein said one or more functions comprises forwarding captured still images and/or video recordings to a destination on a network taking a snapshot.

29. The article of claim 26, wherein said one or more functions comprises setting a motion trigger.

30. The article of claim 26, wherein said one or more functions comprises initiating a video recording of captured images.

23-1. The article of claim 22, wherein said storage medium further comprises machine-readable instructions stored thereon to transmit information descriptive of one or more functional abilities of said camera in response to said poll message.
