Abstract

Data such as image, sound or other media content is delivered between peer devices over a dedicated peer-to-peer communications medium. According to an example embodiment, data is communicated between peer devices respectively belonging to one of a plurality of device classes respectively identified by a device-class identification (ID). Data is stored to identify communications that are to be carried out between devices having respective IDs, such that each pair of IDs has predefined execution steps based upon operational status of the devices. Based upon the device-class ID pair of two peer devices and an operating status of one or both devices, the devices automatically select and execute a communications approach to communicate data therebetween. This communication can be effected in response to a simple user input (e.g., which is specific to neither data nor transfer direction).

Claims

1. A method for communicating data between peer devices over a dedicated peer-to-peer communications medium, each of the peer devices belonging to one of a plurality of device classes respectively identified by a device-class identification (ID), the method comprising:

at each of the devices,

storing data identifying a device-class ID for the device,

storing different sets of control data for respectively controlling peer-to-peer communications between the device and other devices according to the respective device-class IDs of the devices;

at a first one of the devices,

receiving, from a second one of the devices over the peer-to-peer communications medium, a communication that includes information for identifying a device-class ID for the second device, and

in response to a single user input, communicating data between the first and second devices over the communications medium according to

a current operating status of at least one of the devices, and

one of the stored sets of control data for controlling communications between devices respectively having the device-class ID of the first device and the device-class ID of the second device.

2. The method of claim 1, wherein

the first device is a mobile hand-held device,

the second device is a video display device, and

communicating data between the first and second devices according to a current operating status of one of the devices includes wirelessly communicating a currently-displayed image from a television broadcast signal displayed at the video display device to the mobile hand-held device.

3. The method of claim 1, wherein

the first device is a mobile hand-held device,

the second device is a computer having a display, and

communicating data between the first and second devices according to a current operating status of one of the devices includes wirelessly communicating currently-used data from an application running on the computer to the mobile hand-held device.

4. The method of claim 1,

further comprising,

at the first device, sending an initiation transmission over a wireless communications medium in response to the single user input, and

at the second device, monitoring the wireless communications medium to detect the initiation transmission and, in response to the detected transmission, transmitting a wireless communication that includes information for identifying a device-class ID for the second device,

wherein communicating data between the first and second devices in response to a single user input includes

at the first device, sending a communication request to the second device over the wireless communications medium, and

at the second device, communicating data to the first device over the wireless communications medium.

5. The method of claim 1, wherein communicating data between the first and second devices includes communicating over a local wireless communication link having an operable distance of less than about 10 meters.

6. The method of claim 1, wherein communicating data between the first and second devices includes using a directed antenna to communicate over a wireless link exhibiting attenuation that is proportional to a square of the wavelength.

7. The method of claim 1, wherein

the first device also communicates its device-class ID to the second device, and

the second device uses the device-class ID of the first device to identify control data for communicating with the first device.

8. The method of claim 1, wherein communicating data between the first and second devices includes forbidding a communication in response to neither device operating on data amenable for transfer.

9. The method of claim 1, wherein communicating data between the first and second devices includes communicating data according to control data specifying a data type to communicate in accordance with media rights standard data.

10. The method of claim 1, further comprising, after communicating data between the first and second devices, operating one of the devices to provide data for use at the device in response to the control data specifying the operation.

11. A software-programmed computer circuit to store and execute an algorithm to carry out the steps of claim 1.

12. A device for communicating data with other devices over a dedicated, local peer-to-peer wireless communications medium, each of the devices belonging to one of a plurality of device classes respectively identified by a device-class identification (ID), the device comprising:

a storage circuit to store data identifying a local device-class ID for the device, and different sets of control data for respectively controlling peer-to-peer communications between the device and other devices according to the respective device-class IDs of the devices;

a transceiver to wirelessly communicate with peer devices on the wireless communications medium; and

a computer processor circuit connected to the transceiver and programmed to, in response to a single user input,

send the local device-class ID and data identifying a current operating status of the device over the wireless communications medium via the transceiver,

receive, from a remote one of the peer devices and via the transceiver, a device-class ID and a current operating status for the remote device,

retrieve a set of control data for controlling communications between devices respectively having the local and remote device-class IDs, and

facilitate the communication of data between the devices over the wireless communications medium, via the transceiver, according to the retrieved set of control data and the current operating status of at least one of the devices.

13. The device of claim 12, wherein

the device is a television device having a display,

the computer processor circuit is programmed to, in response to a single user input that includes an initiation communication sent to the television device over the wireless communications medium from a mobile hand-held device, the initiation communication specifying a device-class ID and current operating status of the mobile hand-held device,

send file data for a currently-displayed image at the television device to the mobile hand-held device in response to the operating status of the mobile hand-held device indicating that the hand-held device is not displaying an image, and

receive and display image data for an image currently displayed at the mobile hand-held device, in response to the operating status of the mobile hand-held device indicating that the hand-held device is displaying an image.

14. The device of claim 12, wherein

the device is a personal computer (PC) having a display,

the computer processor circuit is programmed to, in response to a single user input that includes an initiation communication sent to the PC over the wireless communications medium from a mobile hand-held device, the initiation communication specifying a device-class ID and current operating status of the mobile hand-held device,
