Abstract

An approach is provided for faceted browsing of video assets. A metadata file is parsed to categorize and rank attributes corresponding to a video asset, wherein the ranked attributes are based on a criterion. A set-top box provides attribute browsing to determine selection of the video asset.

Claims

1. A method comprising:

categorizing, by a processor, a first set of attributes associated with a first list of objects, wherein each of the objects represents a video asset that is associated with one or more of the attributes of the first set;

ranking, by the processor, the first set of attributes according to a criterion associated with one or more characteristics of the attributes, wherein the criterion specifies a frequency of occurrence of an attribute of the first set of attributes;

presenting the first list of objects and associated attributes;

receiving a first input indicating selection of at least one of the attributes of the first set;

collapsing the first list of objects into a second list of objects consisting of a subset of the first list of objects, wherein the subset consists of the objects associated with the selected attributes;

generating, by the processor, a second set of attributes based on the second list of objects, the second set of attributes comprising a non-selected attribute of the first set of attributes, wherein each of the attributes of the second set of attributes is associated with at least one object of the second list of objects;

ranking, by the processor, the second set of attributes according to the criterion, wherein the criterion specifies a frequency of occurrence of an attribute of the second set of attributes;

presenting the second list of objects and associated attributes in response to the first input;

receiving a second input indicating selection of one of the objects in the second list; and

retrieving the video asset corresponding to the one selected object,

wherein the selection of the at least one of the attributes of the first set of attributes specifies a maximum and/or minimum value.

2. A method according to claim 1, further comprising:

receiving a metadata file including the first set of attributes, wherein the categorizing of the first set of attributes includes parsing the metadata.

3. A method according to claim 2, wherein the file has an extensible markup language (XML) format.

4. A method according to claim 2, wherein the file is retrieved on a periodic basis.

5. A method according to claim 1, wherein the video asset includes a video file, a broadcast program, a video game, or a combination thereof.

6. A method according to claim 1, wherein the first input is provided by a user via a remote control device.

7. An apparatus comprising:

a processor configured to categorize and rank a first set of attributes based on a criterion associated with one or more characteristics of the attributes, the first set of attributes being associated with a first list of objects, and to present the first list of objects and associated attributes, wherein each of the objects represents a video asset that is associated with one or more of the attributes of the first set and the criterion specifies a frequency of occurrence of an attribute of the first set of attributes; and

an input interface configured to receive a first input indicating selection of at least one of the attributes of the first set;

wherein the processor is further configured to,

collapse the first list of objects into a second list of objects consisting of a subset of the first list of objects, wherein the subset consists of the objects associated with the selected attributes,

generate a second set of attributes based on the second list of objects, the second set of attributes comprising a non-selected attribute of the first set of attributes, wherein each of the attributes of the second set of attributes is associated with at least one object of the second list of objects,

rank the second set of attributes according to the criterion, wherein the criterion specifies a frequency of occurrence of an attribute of the second set of attributes, and

present the second list of objects and associated attributes in response to the first input; and

wherein the input interface is further configured to receive a second input indicating selection of one of the objects in the second list, in response to which the processor retrieves the video asset corresponding to the one selected object,

wherein the selection of the at least one of the attributes of the first set of attributes specifies a maximum and/or minimum value.

8. An apparatus according to claim 7, wherein the processor is further configured to communicate with a server to obtain a metadata file that includes the first set of attributes, and the categorizing of the first set of attributes includes parsing the metadata.

9. An apparatus according to claim 8, wherein the file has an extensible markup language (XML) format.

10. An apparatus according to claim 8, wherein the file is retrieved on a periodic basis.

11. An apparatus according to claim 7, wherein the video asset includes a video file, a broadcast program, a video game, or a combination thereof.

12. An apparatus according to claim 7, wherein the input interface is configured to receive a signal representing the first input from a remote control device.

13. A system comprising:

an asset parser configured to parse a metadata file to categorize and rank a first set of attributes based on a criterion associated with one or more characteristics of the attributes, the first set of attributes being associated with a first list of objects, wherein each of the objects represents a video asset that is associated with one or more of the attributes of the first set and the criterion specifies a frequency of occurrence of an attribute of the first set of attributes;

an asset server configured to communicate with the asset parser and to transmit the first list of objects and the associated ranked attributes; and

a set-top box, wherein the set-top box is configured to present the first list of objects and associated ranked attributes;

wherein, responsive to a first input indicating a selection of at least one of the attributes of the first set, the asset parser is further configured to,

collapse the first list of objects into a second list of objects consisting of a subset of the first list of objects, wherein the subset consists of the objects associated with the selected attributes,

generate a second set of attributes based on the second list of objects, the second set of attributes comprising a non-selected attribute of the first set of attributes, wherein each of the attributes of the second set of attributes is associated with at least one object of the second list of objects, and

rank the second set of attributes according to the criterion, wherein the criterion specifies a frequency of occurrence of an attribute of the second set of attributes;

wherein the asset server is further configured to transmit the second list of objects and associated ranked attributes to the set-top box; and

wherein the set-top box is further configured to present the second list of objects and associated ranked attributes, and, responsive to a second input indicating a selection of one of the objects in the second list, to retrieve the video asset corresponding to the one selected object,

wherein the selection of the at least one of the attributes of the first set of attributes specifies a maximum and/or minimum value.

14. A system according to claim 13, wherein the metadata file has an extensible markup language (XML) format.

15. A system according to claim 13, wherein the video asset includes a video file, a broadcast program, a video game, or a combination thereof.

16. A system according to claim 13, wherein the asset parser receives the metadata file from a content provider system that maintains the video asset.

17. A system according to claim 13, further comprising:

a rules database configured to store a plurality of rules for ranking the attributes.
