Abstract

A multimedia control method is provided, which includes the following steps. Communicate a mobile device with at least one audio device. Determine at least one relative location between the mobile device and at least one of the audio device. Control the at least one audio device according to the at least one relative location.

Claims

1. A multimedia control method, comprising:

communicating a mobile device with at least one audio device;

determining at least one relative location between the mobile device and at least one of the audio device;

controlling the at least one audio device according to the at least one relative location.

2. The audio control method according to claim 1, further comprising:

receiving a wireless signal from the at least one audio device;

determining the distance according to signal strength of the wireless signal.

3. The audio control method according to claim 1, further comprising:

determining relative distance of each of the at least one audio device to the mobile device;

controlling volume of each of the at least one audio device according to the relative distance by the mobile device.

4. The audio control method of claim 1, wherein the controlling of the at least one audio device further comprises adjusting amplifying gain of a recording track.

5. The audio control method of claim 1, further comprising:

transmitting an audio track from the mobile device to the at least one audio device.

6. The audio control method of claim 1, wherein the controlling step further comprising:

transmitting a control signal from the mobile device to the at least one audio device.

7. The audio control method of claim 1, wherein the controlling step further comprising:

transmitting a control signal from one of the at least one audio device to the remaining of the at least one audio device.

8. The audio control method of claim 1, wherein the controlling step further comprising:

receiving a control signal at one of the at least one audio device;

transmitting the control signal to the remaining of the at least one audio device.

9. A multimedia control method for use in a mobile device, comprising:

connecting the mobile device to a multimedia device wirelessly;

sending multimedia data to the multimedia device for output;

determining a relative distance to the multimedia device according to a wireless signal received from the multimedia device; and

controlling output of the multimedia data on the multimedia device.

10. The multimedia control method of claim 9, further comprising:

connecting to a second multimedia device wirelessly;

determining a second relative distance to the second multimedia device; and

switching output of the multimedia data to the second multimedia device according to the second relative distance.

11. The multimedia control method of claim 10, wherein the switching further comprising:

terminating output of the multimedia device in response to the relative distance is greater than a predefined threshold.

12. The multimedia control method of claim 9, wherein the relative distance is determined according to a predefined relationship with signal strength.

13. The multimedia control method of claim 9, wherein the relative distance is determined according to a proximity profile of Bluetooth low energy (BLE).

15. The multimedia control method of claim 9, wherein the controlling of the multimedia data comprises at least one of the following:

adjusting volume level of the multimedia device;

adjusting time delay of the multimedia data;

switching output to another multimedia data; and

terminating output of the multimedia data.

14. The multimedia control method of 9, wherein the determining and the controlling are performed dynamically in a predefined basis.

16. A multimedia control system, comprising:

a wireless interface unit, configured to receive a wireless signal;

a processing unit, configured to determine location information according the wireless signal; and

a control unit, configured to determine control operation according to the location information.

17. The multimedia control system of claim 16, wherein the processing unit determines a relative distance to a multimedia device according to signal strength of the wireless signal received.

18. The multimedia control system of claim 17, wherein the control unit control audio output of a multimedia device according to the relative distance.

19. The multimedia system of claim 16, the control unit is further configured to provide a control signal corresponding to the control operation and multimedia data via the wireless interface unit

20. The multimedia system of claim 16, wherein the multimedia system is implemented in a mobile device and the wireless signal is in Bluetooth low energy (BLE) protocol.
