  • Figure 6 illustrates a method 600 for wirelessly providing a content stored in a content source, such as the cellular telephone 142, to a content player, such as the car audio system 143.
  • the method 600 is described with respect to Figures 1-5 by way of example and not of limitation. It will thus be apparent to one of ordinary skill in the art that the method 600 may be performed with systems and devices other than those depicted in Figures 1-5.
  • the wireless adaptor 173 (or 573) establishes a wired communication link with a content player, such as the car audio system 143, through an I/O interface on the wireless adaptor 173, such as the I/O interface 450, wire-connected to an I/O interface on the content player.
  • the wireless adaptor 173 detects a presence of a content source nearby or in proximity to the wireless adaptor 173 (or 573).
  • the wireless adaptor 173 also establishes a wireless communication link with a nearby content source, such as the cellular telephone 142, through a wireless proximity network, such as a Bluetooth or Wi-Fi network, to access the content stored in the cellular telephone 142.
  • a nearby content source such as the cellular telephone 142
  • a wireless proximity network such as a Bluetooth or Wi-Fi network
  • the wireless proximity network is facilitated by the application profiles stack 420, in the case of the wireless adaptor 173, or a transceiver such as a Bluetooth or Wi-Fi USB key that is connectible to the wireless adaptor, in the case of the wireless adaptor 573.
  • the wireless adaptor 173 receives content, such as audio content, from the content source via the wireless communication link as established wireless proximity network.
  • the wireless adaptor 173 also receives a request from the content player for a functional control of the content source, such as a selection of a content channel available in the content source.
  • FIGS. 4 and 5 include both hardware and software, hi one embodiment, each of the wireless adaptors 173 and 573 is implemented as a System-on-a-Chip (SoC) solution, with one or more computer chips, each includes one or more processors, such as microprocessors or digital signal processors, and one or more CRMs that include program codes for the implementation of the application profiles stack 420, the network manager 430, the commands translations module 490, the I/O manager 495, the decoder 440, the IR/RF commands module 470, and the speech commands module 470.
