Abstract

A media transfer and control system that includes a handheld device and an audio/visual system. The media transfer and control system provides for: (i) the transfer of media files between the handheld device and the audio/visual system, (ii) the transmission of control commands from the handheld device to the audio/visual system for controlling the function and operation of the audio/visual system through a user interface provided on the handheld device, and (iii) the unsolicited transfer of media descriptive data between the handheld device and the audio/visual system to create a synchronized global view on the handheld electronic device and/or the audio/visual system of all of the media content currently stored on and/or available through both the handheld device and the audio/visual system.

Claims

1. A handheld electronic device configured to communicate wirelessly with a target device, through a logical channel, the handheld electronic device and the target device being configured to store and play media files, the handheld electronic device being configured to display media descriptive data associated with media files, the handheld electronic device comprising:

a processor;

a memory operationally connected to the processor, the memory to store handheld device media files comprised of handheld device media file data; and

a transceiver operationally connected to the processor, the processor being configured to cause the transceiver to transmit, through the logical channel, handheld device media file data to the target device, the processor also being configured to cause the transceiver to transmit, through the logical channel, control data to the target device, the control data to control actions of the target device with respect to the handheld device media data transmitted from the transceiver, the control data and the handheld device media file data being packetized data, when the handheld electronic device plays a selected media file and when the handheld electronic device and the target device become within communication range, at which communication range the handheld electronic device and the target device establish communication, the communication being established at a time when the selected media file has played up to a played portion of the selected media file, the transceiver transmits to the target device handheld electronic device media data associated with the selected media file and the control data causes the target device to start streaming the selected media file starting substantially immediately subsequent the played portion of the selected media file.

2. The handheld electronic device of claim 1 wherein the control data is interspersed with handheld media file data.

3. The handheld electronic device of claim 2 wherein:

packets of control data include header information designating them as control data packets; and

packets of handheld device media file data include header information designating them as handheld device media file data packets.

4. The handheld electronic device of claim 1 wherein the processor is further configured to cause the transceiver to transmit, to the target device, an alert sequence, the alert sequence to alert the target device that a data packet to be transmitted by the transceiver subsequent the alert sequence will be a control data packet.

5. The handheld electronic device of claim 4 wherein the alert sequence is comprised in a handheld device media file data packet.

6. The handheld electronic device of claim 1 wherein to communicate wirelessly includes to communicate using radio frequency signals.

7. The handheld electronic device of claim 1 wherein to communicate wirelessly includes to communicate using infrared signals.

8. The handheld electronic device of claim 1 wherein the actions of the target device include storing the handheld media device data on the target device to obtain a stored handheld device media file.

9. The handheld electronic device of claim 8 wherein the actions of the target device include playing the stored handheld device media file.

10. The handheld electronic device of claim 1 wherein the actions of the target device include causing the target device to play the handheld device media file as the target device receives the handheld device media data from the transceiver.

11. The handheld electronic device of claim 1 wherein:

the target device has stored therein a target device media file having associated thereto target device media descriptive data; and

the processor being configured to cause the transceiver to receive from the target device, through the logical channel, the target device media descriptive data to obtain received target device media descriptive data.

12. The handheld electronic device of claim 11 wherein the processor is further configured to determine, in accordance with the received target device media descriptive data, if the memory has stored therein a copy of the target device media file.

13. The handheld electronic device of claim 11 wherein the processor is further configured to cause the received target device media descriptive data to be displayed on the handheld electronic device to obtain displayed target device media descriptive data.

14. The handheld electronic device of claim 13 further comprising an input system operationally connected to the processor, the control data to cause the target device media file to be played on the target device upon selection, from the input system, of the displayed target device media descriptive data.
