Problems solved by technology
This presents an interoperability dilemma: what to do if one device uses content protection and the other does not?
Simply not allowing the connection may be too strict and may not be acceptable to users.
However allowing the connection would completely circumvent the content protection.

A method and system that configure communication between devices in a network, where one device may support content protection, and another device may or may not support content protection. The devices may support communication utilizing Bluetooth® technology. A first device may determine whether a second device provides content protection support. If the second device does not support content protection, the first device may utilize a configuration that does not require content protection for communicating data with the second device. If the second device supports content protection, the first device may utilize a configuration that requires content protection for communicating data. If communicating data utilizing content protection fails, the first device may revert to utilizing a configuration that does not require content protection for communicating data with the second device.
Description
RELATED APPLICATIONS [0001] This application makes reference to U.S. patent application Ser. No. 11 / 019,072 (Attorney Docket No. 16063US02) filed Dec. 21, 2004, the complete subject matter of which is hereby incorporated herein by reference, in its entirety.FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] [Not Applicable]MICROFICHE / COPYRIGHT REFERENCE [0003] [Not Applicable]BACKGROUND OF THE INVENTION [0004] Bluetooth® wireless technology is set to revolutionize personal connectivity by providing freedom from wired connections. Bluetooth® is a specification for a small form-factor, low-cost radio solution providing links between mobile computers, mobile phones and other portable and handheld devices. [0005] Bluetooth® wireless technology is an international, open standard for allowing intelligent devices to communicate with each other through wireless, short-range communications. This technology allows any sort of Bluetooth® compliant device—from computers and cell phones to keybo...
