Abstract

Media fingerprints, which are each derived from and uniquely correspond to a portion of media content, are stored over a distributed database. An instance of one or more information containers of the distributed database are each disposed over two or more computing devices, which are communicatively linked over a data network. The media fingerprints are distributed among the information containers based on a criterion that relates individually to each of the media fingerprints. Upon a query directed to one of the media fingerprints, at least one of the two or more computing devices is selected based on the criterion. The query is executed over the distributed database instance of the selected computing device.

Claims

1. A method for redistributing media fingerprints over a plurality of distributed fingerprint database information container instances of a distributed fingerprint database, the method comprising the steps of:

redistributing a plurality of media fingerprints, which are each derived from and uniquely correspond to a portion of media content, over the distributed fingerprint database upon a change of at least a first criterion that relates individually to each of the media fingerprints;

wherein a distributed fingerprint database information container instance of one or more distributed fingerprint database information containers of the distributed fingerprint database are each disposed over two or more computing devices, which are communicatively coupled over a data network; and

wherein the redistributing step comprises the steps of;

storing each of the plurality of media fingerprints among those distributed fingerprint database information container instances that are selected based on at least the first criterion;

deleting each of the plurality of media fingerprints from those distributed fingerprint database information container instances that are no longer selected based on at least the first criterion;

wherein the first criterion relates to one or more of a timeliness, a value, or statistical information, which are associated with one or more of the media content or the media fingerprint derived therefrom and uniquely corresponding thereto;

upon a query generated or submitted in relation to one of the media fingerprints, selecting at least one of the two or more computing devices based on one or more of at least the first criterion, or the first criterion and a second criterion; and

executing the query over the distributed fingerprint database information container instance of the selected at least one computing device.

2. The method as recited in claim 1 wherein the first criterion relates to one or more of a timeliness, a value, or statistical information, which are is associated with one or more of the media content or the media fingerprint derived therefrom and uniquely corresponding thereto.

3. The method as recited in claim 1 wherein the selecting step is also performed based on the second criterion;

wherein the second criterion relates to a characteristic of the at least one of the computing devices; and

wherein the characteristic relates to one or more of;

one or more of a location of the at least one computing device;

one or more of a computational attribute or a networking attribute of the at least one computing device at query time;

one or more of statistical information relating to, a latency associated with, or an availability of the computing device over the data network at query time;

or

a condition of the data network at query time.

wherein the query relates to the media content instance;

wherein the method further comprising the steps of;

computing the query;

returning a result based on the computing step; and

acting in relation to the streaming of the media content instance based on the returned result of the query.

5. The method as recited in claim 4 wherein the acting step comprises the step of:

controlling the streaming of the media content instance;

wherein the controlling step comprises one or more of the steps of;

deterring the streaming of the media content instance;

or

providing information that is associated with the media content instance in at least near real time in relation to the streaming of the media content instance;

wherein the media content instance streams to an entity that is communicatively coupled with the data network upon a request from the entity to access the media content; and

wherein the deterring step comprises the step of;

deterring the streaming of the media content instance to the entity; and

allowing the media content instance to stream over a portion of the data network apart from the entity.

6. The method as recited in claim 2 wherein the statistical information relates to a likelihood that the media content will be requested for access

wherein the method further comprises the step of:

determining the likelihood that the media content will be requested for access; and

wherein the step of redistributing the media fingerprints comprises the step of dynamically changing a storage location of one or more of the media content or the media fingerprint based on the determined likelihood.

7. The method as recited in claim 2 wherein the statistical information relates to a usage statistics of the media fingerprint that will be requested for access;

and

wherein each distributed fingerprint database information container instance assigned to a class represents the usage statistics of its stored media fingerprints;

wherein the method further comprises the step of;

determining the usage statistics of the media fingerprint that will be requested for access; and

wherein, upon the usage statistics rising, the step of dynamically changing a storage location of one or more of the media content or the media fingerprint based on the changing statistical information comprises moving the one or more of the media content or the media fingerprint to a distributed fingerprint database information container instance of a higher class; and

wherein, upon the usage statistics falling, the step of dynamically changing a storage location of one or more of the media content or the media fingerprint based on the changing statistical information comprises moving the one or more of the media content or the media fingerprint to a distributed fingerprint database information container instance of a lower class.

8. The method as recited in claim 1, prior to the redistributing step further comprising the step of:

distributing a plurality of media fingerprints, which are each derived from and uniquely correspond to a portion of media content, over the distributed fingerprint database;

wherein the distributing step comprises the step of;

storing each of the plurality of media fingerprints among the one or more distributed fingerprint database information container instances that are selected based on at least the first criterion.

9. The method as recited in claim 1 wherein the redistributing step comprises the step of:

dynamically reassigning a storage location for at least one of the media fingerprints from one or more first distributed fingerprint database information container instances to at least one distributed fingerprint database information container instance of at least one of the computing devices, which is apart from the first of the distributed fingerprint database information container instances.
