Abstract
Systems and methods are provided for controlling which of multiple data interfaces in an electronic device is used for communication with another electronic device so as to minimize disruption of the user experience. In one embodiment, a switch may be provided that is configured to maintain the data stream through a presently used data interface even when other data interfaces become physically connected or available for data transfer. Benefits of unused, but nevertheless connected data interfaces may be received by the electronic device without initiating a transfer of the communication duties between interfaces.
Claims24
An electronic device configured to communicate with a second device, the electronic device comprising:
- an element for handling a data stream;
- a plurality of data interfaces, each capable of individually carrying the data stream between the electronic device and the second device;
- a switch for controlling which of the plurality of data interfaces is presently used to carry the data stream between the electronic device and the second device, wherein the switch is configured to maintain the data stream through a presently used data interface when a plug-and-play data interface becomes physically connected to the second device or becomes available to carry the data stream between the electronic device and the second device.
A camera configured to communicate with a second device, the camera comprising:
- a signal source generating an image data stream;
- a wireless data interface for carrying the data stream to the second device;
- a wired data interface for carrying the data stream to the second device;
- wherein each interface is capable of individually carrying the data stream;
- a switch for controlling which of the interfaces is used to carry the data stream to the second device, wherein the switch is configured to maintain the data stream through the wireless data interface when the wireless data interface is in use and a plug associated with the wired data interface becomes physically connected to the second device.
A method of controlling an electronic device in communication with a second device, the method comprising:
- generating a data stream;
- controlling which of a plurality of data interfaces is presently used to carry the data stream between the electronic device and the second device;
- maintaining the data stream through a presently used data interface when a plug-and-play data interface becomes physically connected to the second device or becomes available to carry the data stream to the second device.
An electronic device configured to communicate with a second device, the electronic device comprising:
- a wireless interface;
- a USB wired interface;
- and
- a switch for selectively disabling the data lines of said USB wired interface so that said wired interface can be used for data transfer or for only providing power to said electronic device.
