Abstract

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for creating and using media asset proxies. The media asset proxies represent a digital media asset and are created by filtering and modifying elements from the digital media asset. The media asset proxies can be queried in the same manner as their corresponding digital media asset.

First claim

We claim:

1. A computer-implemented method, comprising:
parsing a digital media asset having media data to identify a plurality of elements;
removing a portion of the plurality of elements according to a removal criteria to yield a reduced plurality of elements, wherein the removal criteria specifies removal of any identified element that includes either media data or metadata that is unneeded for responding to a set of queries supported by the digital media asset;
modifying one or more elements of the reduced plurality of elements according to a predetermined algorithm; and
creating a media asset proxy to represent the digital media asset, the media asset proxy excluding the elements identified by the removal criteria and supporting the set of queries supported by the digital media asset, wherein the media asset proxy is created using the reduced plurality of elements that includes the one or more elements modified according to the predetermined algorithm.

2. The computer-implemented method of claim 1 , wherein the removal criteria comprises a list of element types that are to be excluded from the media asset proxy.

3. The computer-implemented method of claim 1 , wherein the predetermined algorithm comprises:
truncating at least one element from the reduced plurality of elements, the at least one element having no effect on the media asset proxy supporting the set of queries.

4. The computer-implemented method of claim 1 , wherein the predetermined algorithm comprises:
encoding at least one element from the reduced plurality of elements into a smaller size, the at least one element having no effect on the media asset proxy supporting the set of queries.

5. The computer-implemented method of claim 1 , further comprising:
creating a second media asset proxy to represent a second digital media asset, the media asset proxy and the second media asset proxy having substantially equivalent file sizes.

6. The computer-implemented method of claim 1 , wherein the digital media asset is a digital movie file.

7. A computer-implemented method, comprising:
parsing a digital media asset having media data to identify a plurality of elements;
removing a portion of the plurality of elements according to a removal criteria to yield a reduced plurality of elements;
modifying one or more elements of the reduced plurality of elements based, at least in part, on encoding at least one element from the reduced plurality of elements, wherein the at least one element comprises a data structure indicative of time and data indexing pairs for the digital media asset, and wherein the encoding comprises creating a new data structure summarizing the data structure that is indicative of time and data indexing pairs for the digital media asset; and
creating a media asset proxy to represent the digital media asset, the media asset proxy excluding the media data and supporting a set of queries supported by the digital media asset, wherein the media asset proxy is created using the reduced plurality of elements that includes the one or more elements modified according to the predetermined algorithm.

8. A non-transitory computer-readable storage medium having stored thereon instructions which, when executed by a processor, cause the processor to perform operations comprising:
parsing a digital media asset having media data to identify a plurality of elements;
removing a portion of the plurality of elements according to an omission filter to yield a reduced plurality of elements, wherein the omission filter specifies removal of any identified element that includes either media data or metadata that is unneeded for responding to a set of queries supported by the digital media asset;
modifying one or more elements of the reduced plurality of elements according to a predetermined algorithm; and
creating a media asset proxy to represent the digital media asset, the media asset proxy excluding the elements identified by the removal criteria and supporting the set of queries supported by the digital media asset, wherein the media asset proxy is created using the reduced plurality of elements that includes the one or more elements modified according to the predetermined algorithm.

9. The computer-readable storage medium of claim 8 , wherein the parsing further identifies a hierarchy among the plurality of elements, wherein at least one element from the plurality of elements is a container for at least another element from the plurality of elements.

10. The computer-readable storage medium of claim 8 , wherein the omission filter removes one or more element types that are not required to support the set of queries.

11. The computer-readable storage medium of claim 8 , wherein the predetermined algorithm comprises:
truncating at least one element from the reduced plurality of elements, the at least one element having no effect on the media asset proxy supporting the set of queries.

12. The computer-readable storage medium of claim 8 , wherein the predetermined algorithm comprises:
encoding at least one element from the reduced plurality of elements into a smaller size, the at least one element having no effect on the media asset proxy supporting the set of queries.

13. The computer-readable storage medium of claim 8 , the operations further comprising:
creating a second media asset proxy to represent a second digital media asset, the media asset proxy and the second media asset proxy having substantially equivalent file sizes.

14. A non-transitory computer-readable storage medium having stored thereon instructions which, when executed by a processor, cause the processor to perform operations comprising:
parsing a digital media asset having media data to identify a plurality of elements;
removing a portion of the plurality of elements according to an omission filter to yield a reduced plurality of elements;
modifying one or more elements of the reduced plurality of elements based, at least in part, on truncating at least one element from the reduced plurality of elements, wherein the at least one element comprises a data structure indicative of time and data indexing pairs for the digital media asset, and wherein the truncating comprises creating a new data structure summarizing the data structure that is indicative of time and data indexing pairs for the digital media asset; and
creating a media asset proxy to represent the digital media asset, the media asset proxy excluding the media data and supporting a set of queries supported by the digital media asset, wherein the media asset proxy is created using the reduced plurality of elements that includes the one or more elements modified according to the predetermined algorithm.

15. A client device comprising:
a processor; and
a computer readable medium, having stored thereon a plurality of instructions for causing the processor to perform operations comprising:
parsing a digital media asset having media data to identify a plurality of elements;
removing a portion of the plurality of elements according to a removal criteria to yield a reduced plurality of elements, wherein the removal criteria specifies removal of any identified element that includes either media data or metadata that is unneeded for responding to a set of queries supported by the digital media asset;
modifying one or more elements of the reduced plurality of elements according to a predetermined algorithm; and
creating a media asset proxy to represent the digital media asset, the media asset proxy excluding the elements identified by the removal criteria and supporting the set of queries supported by the digital media
