Abstract

It is provided a method for triggering an action on a second device. It comprises the steps of obtaining audio of a multimedia content presented on a first device; comparing the obtained audio with reference audio data in a database; if finding the obtained audio exists in the database containing reference audio, determining an action corresponding to the matched reference audio; and triggering the action in the second device.

Claims

1. A method comprising:

obtaining, by a first device, audio of multimedia content presented on a second device;

sampling, by the first device, the audio at a sampling frequency;

determining, by the first device, a maximum value, a minimum value and distribution information from the sampled audio based on at least one amplitude value of the sampled audio;

searching, by the first device, a database for a reference audio using the maximum value, the minimum value, the distribution information, and the sampling frequency of the sampled audio as search criteria;

when the reference audio is found in the database, determining, by the first device, an action corresponding to the reference audio, wherein the reference audio is found in the database at least based on a matching of the sampling frequency of the audio and the reference audio; and

performing, by the first device, the action in the first device.

2. The method of claim 1, wherein the action comprises at least one of:

start presenting the multimedia content;

stop presenting the multimedia content; and

carry out a control action on a physical device such as turning on or off said physical device.

3. The method of claim 2, further comprising:

using, by the first device, a voice recognition technique on the obtained audio to determine the multimedia content to be presented on the first device, when the action is to start presenting multimedia content on the first device; and

use a result of the voice recognition technique to determine the multimedia content to present on the device.

4. The method of claim 1, further comprising:

using, by the first device, a user profile to determine the action among two or more candidate actions so as to satisfy a user preference.

5. The method of claim 4, further comprising:

providing, by the first device, a user interface for collecting user feedback after the action is performed so as to update the user profile.

6. The method of claim 1, further comprising:

storing, by the first device, at least one user profile,

using, by the first device, the stored user profile to select the action among two or more candidate actions corresponding to the reference audio.

7. A device comprising:

a memory;

at least one processor coupled to the memory, wherein the at least one processor is configured to;

obtain audio of multimedia content presented on a different device;

sample the audio at a sampling frequency;

determine a maximum value, a minimum value and distribution information from the sampled audio based on at least one amplitude value of the sampled audio;

search a database for a reference audio using the maximum value, the minimum value, the distribution information, and the sampling frequency of the sampled audio as search criteria;

when the reference audio is found in the database, determine an action corresponding to the reference audio, wherein the reference audio is found in the database at least based on a matching of the sampling frequency of the audio and the reference audio; and

perform the determined action.

8. The device of claim 7, wherein the at least one processor is further configured to:

use a voice recognition technique on the obtained audio to determine the multimedia content to be presented by the device, when the action is to start presenting multimedia content on the device; and

use a result of the voice recognition technique to determine the multimedia content to present on the device.

9. The device of claim 7, wherein the at least one processor is further configured to:

store at least one user profile,

use the stored user profile to select the action among two or more candidate actions corresponding to the reference audio.

10. The device of claim 7, wherein the action comprises at least one of:

start presenting the multimedia content;

stop presenting the multimedia content; and

carry out a control action on a physical device such as turning on or off said physical device.

11. The device of claim 7, wherein the at least one processor is further configured to:

use a user profile to determine the action among two or more candidate actions so as to satisfy a user preference.

12. The device of claim 11, wherein the processor is further configured to:

provide a user interface for collecting user feedback after the action is performed so as to update the user profile.
