Abstract

A method for generating a unified list of media services available from a plurality of content aggregators having different data formats. A first list of media services from a first content aggregator is transmitted to a playback device. A second list of media services from a second content aggregator is also transmitted to the playback device, which combines both lists into a unified list of media services. The method optionally details the playback of a media service from said plurality of content aggregators via a selection made on the unified list to a playback device.

Claims

1. A method of processing media services, as performed by a playback device with a processor, from a plurality of content aggregators through a communications network comprising the steps of:

said playback device receiving a first media service list from a first content aggregator from a plurality of content aggregators,

said playback device receiving a second media service list from a second content aggregator from said plurality of content aggregators, wherein said second media service list has a data structure incompatible with a data structure said first media service list;

said playback device translating said first media service list and said second service list into a unified media service list comprising media services wherein said unified media service list is the same data structure of at least one of;

said first media service list, and said second media service list; and

said playback device downloads a first codec to play a first media service present on said unified media service, in response to a user selection of said first media service, when said first media service is in a format that requires said first codec for playback.

2. The method of claim 1 further comprising an additional step of displaying said unified media service list.

3. The method of claim 2 further comprising additional steps of:

requesting a media service displayed on said unified media service list, wherein a location of said media service is identified by a corresponding uniform resource locator from said plurality of uniform resource locators;

receiving said media service; and

outputting said media service.

4. The method of claim 3, wherein

said media service is output from a device comprising at least one of:

a portable audio device, a stereo, an Internet radio, a computer, a telephone, an Internet enabled device and a memory device.

5. The method of claim 3, wherein

said output comprises a function selected from at least one of:

playing, copying, and transmitting said media service to a playback device.

6. The method of claim 3, wherein

said media service is in a format comprising at least one type of media extension from the group of:

.ram, .rm, .rpm, .mov, .qif, .wma, .cmr, .avi, .swf, .swl, .mpg, .mpa, .mp1, .mp2, .mp3, .m3a, and .m3u.

7. The method of claim 1, wherein

the data structure of said first content aggregator is defined by a document type definition (DTD).

8. The method of claim 1, wherein

said plurality of content aggregator comprises at least one of a website, a server, a web-enabled device, a radio, a data storage device, an on-demand subscription service, tuning service, peer to peer media service, and a broadcast service.

9. The method of claim 1, wherein a third media service list is translated and merged in said unified media service list.

10. The method of claim 2 wherein

said unified media service list is organized by at least one of:

a genre of said media service, a media service author, a copyright data, a media service date of transmission, a performer, a title, a subject, a parental rating, a user rating, a director, a producer, a running length of said media service, and a language.

11. The method of claim 3, wherein

said media service is from a content aggregator from said plurality of content aggregators.

12. The method of claim 3, wherein

said media service is received from a location associated with a content aggregator from said plurality of content aggregators.

13. The method of claim 2, wherein

said first media service list is associated with an first XML data format and said second media service list is associated with a different XML data format, such that the unified media service list will convert both the first XML data format and said different XML data format into an XML format compatible with said unified media service list.

14. The method of claim 2, wherein

said unified media service list is formatted by using metadata from said unified media service list and checking such metadata by use of an external database and

said first and second content aggregators are accessed via the same external communication network using a same interface.

15. The method of claim 10 where an external database is queried to provide metadata supporting said grouping operation where metadata from said media services are matched to said metadata from said external database.
