Abstract

Example methods and systems for modifying the playback of content using pre-processed profile information are described. In some example embodiments, the methods and systems may access a stream of content to be delivered to a playback device, identify a piece of content within the stream of content to be delivered to the playback device, determine a profile for the identified piece of content, and deliver the determined profile to the playback device. In some example embodiments, the methods and systems may receive a stream of content at a playback device, access profile information associated with the stream of content, and modify playback of the stream of content based on the accessed profile information.

Claims

1. A method comprising:

accessing, by executing an instruction with a processor, a media stream to be provided to a device via a network, the media stream including a piece of media;

identifying, by executing an instruction with the processor, the piece of media using a comparison of a reference fingerprint of the piece of media to a query fingerprint generated based on the piece of media;

selecting, by executing an instruction with the processor, a profile of equalization parameters from a plurality of profiles, the selected profile corresponding to the identified piece of media and specifying at least one corresponding output frequency parameter to be used when outputting the piece of media at the device, the selecting of the profile being enabled by the identifying of the piece of media; and

providing, in response to the selection of the profile of equalization parameters and by executing an instruction with the processor, the selected profile of equalization parameters and the media stream to the device via the network.

2. The method of claim 1, wherein the selected profile of equalization parameters specifies the at least one corresponding output frequency parameter by specifying a frequency equalization setting for the piece of media.

3. The method of claim 1, wherein:

the selected profile of equalization parameters is included in a selected profile of equalization parameters that corresponds to the identified piece of media and specifies at least one of a virtualization setting for the piece of media or a spatialization setting for the piece of media.

4. The method of claim 1, wherein:

the selected profile of equalization parameters specifies the at least one corresponding output frequency parameter by specifying a video modification parameter selected from a group consisting of;

a color temperature for the piece of media and a color palette for the piece of media.

5. The method of claim 1, wherein:

the selected profile of equalization parameters includes a plurality of sub-profiles of equalization parameters, each of the plurality of sub-profiles corresponding to a different portion of the piece of media, a first sub-profile corresponding to a first portion of the piece of media and specifying a first output frequency parameter for the first portion, a second sub-profile corresponding to a second portion of the piece of media and specifying a second output frequency parameter for the second portion.

6. The method of claim 5, wherein:

the first portion of the piece of media has a first musical tempo, and the first output frequency parameter specified by the first sub-profile corresponds to the first musical tempo; and

the second portion of the piece of media has a second musical tempo, and the second output frequency parameter specified by the second sub-profile corresponds to the second musical tempo.

7. The method of claim 1, wherein:

the profile of equalization parameters corresponds to a genre of the identified piece of media, the genre being selected from a plurality of available genres of media; and

the selecting of the profile of equalization parameters includes selecting the profile based on the genre of the identified piece of media.

8. The method of claim 1, wherein:

the profile of equalization parameters corresponds to a mood of the identified piece of media, the mood being selected from a plurality of available moods of media; and

the selecting of the profile of equalization parameters includes selecting the profile based on the mood of the identified piece of media.

9. A system comprising:

one or more hardware processors; and

a memory storing instructions that, when executed by the one or more hardware processors, cause the system to at least;

access a media stream to be provided to a device via a network, the media stream including a piece of media;

identify the piece of media using a comparison of a reference fingerprint of the piece of media to a query fingerprint generated based on the piece of media;

select a profile of equalization parameters from a plurality of profiles, the selected profile corresponding to the identified piece of media and specifying at least one corresponding output frequency parameter to be used when outputting the piece of media, the selecting of the profile being enabled by the identifying of the piece of media; and

provide, in response to the selection of the profile, the selected profile of equalization parameters and the media stream to the device via the network.

10. A non-transitory machine-readable storage medium comprising instructions that, when executed by one or more hardware processors of a machine, cause the machine to at least:

access a media stream to be provided to a device via a network, the media stream including a piece of media;

identify the piece of media using a comparison of a reference fingerprint of the piece of the media to a query fingerprint generated based on the piece of media;

select a profile of equalization parameters from a plurality of profiles, the selected profile corresponding to the identified piece of media and specifying at least one corresponding output frequency parameter to be used when outputting the piece of media, the selecting of the profile being enabled by the identifying of the piece of media; and

provide, in response to the selection of the profile of equalization parameters, the selected profile of equalization parameters and the media stream to the device via the network.
