Abstract

Various embodiments of the invention provide a method, apparatus, system and computer readable medium for implementing a universal media interface and control protocol to control a universal media apparatus. The universal media interface and its control protocol facilitate communication, including issuance of generalized commands between a target device, such as an audio/video (“A/V”) device and a universal music player, thereby enabling the target device to play music from different types of music servers and specialized server processes.

Claims

1. An apparatus for providing music-related requests from a target electronic device to one or more specialized music servers operating with different server protocols, said apparatus comprising:

a request decoder configured to decode a music-related request to communicate with at least one specialized music server using one of a plurality of different server protocols;

a command control protocol module configured to generate a generalized music-related command in response to said music-related request;

a universal music apparatus module configured to access multiple specialized music servers in response to said generalized music-related command; and

a universal media data link configured to convey said generalized music-related command from said command control protocol module to said universal music apparatus module,

wherein said multiple specialized music servers implement incompatible server protocols.

2. The apparatus of claim 1 wherein said command control protocol module is further configured to generate a music-related command for forming a play list of songs for playing,

wherein said play list includes songs composed of music data stored on said multiple specialized music servers.

3. The apparatus of claim 1 wherein said command control protocol module is further configured to generate a synchronous music-related command requiring a response from said universal music apparatus module before said command control protocol module transmits a subsequent music-related command.

4. The apparatus of claim 3 wherein said synchronous music-related command is a single command that causes said universal music apparatus module to identify said multiple specialized music servers using different discovery protocols.

5. The apparatus of claim 1 wherein said command control protocol module is further configured to generate an asynchronous music-related command that forms one or more responses as said universal music apparatus module performs one or more subsequent music-related commands.

6. The apparatus of claim 5 wherein said asynchronous music-related command is a single command that causes said universal music apparatus module to retrieve music-related information from said multiple specialized music servers using different communication protocols.

7. The apparatus of claim 6 wherein said music-related information includes information about artists, titles, composers, genres, albums and play lists.

8. The apparatus of claim 1 wherein said apparatus is formed on substrate including either a printed circuit board (“

PCB”

) or a semiconductor wafer.

9. A computer readable medium including executable instructions to provide music-related requests from a target electronic device to multiple specialized music servers operating with different server protocols via a network, said computer readable medium comprising executable instructions to:

detect a request to access music associated with said multiple specialized music servers; and

decode said request as either a synchronous command or an asynchronous command, either of which is configured to access any of said multiple specialized music servers,

wherein said synchronous command and said asynchronous command are generalized commands.

10. The computer readable medium of claim 9 further comprising executable instructions to transmit either said synchronous command or said asynchronous command to a universal music apparatus module, which generates server-specific commands associated with said generalized commands.

11. The computer readable medium of claim 9 wherein said synchronous command is a single ListServers command for generating a list of one or more of said multiple specialized music servers using multiple discovery protocols.

12. The computer readable medium of claim 9 wherein said synchronous command is a single SetServerFilter command for selecting one or more subsets of multiple specialized music servers, at least one of said subsets including music servers sharing a common communications protocol.

13. The computer readable medium of claim 12 wherein others subsets include one or more of the following:

a portable media device including a flash memory-based device, a list of internet radio stations, and a radio tuner.

14. The computer readable medium of claim 9 wherein said asynchronous command is a single command to generate a list relating to one of the following music-related information from said multiple specialized music servers:

songs, albums, artists, composers, genres, play lists, and play list songs.

15. The computer readable medium of claim 14 wherein said asynchronous command includes a string of alpha-numeric characters as an argument for searching said multiple specialized music servers to retrieve music-related information for a particular song, album, artist composer, genre, play list, or play list songs.

16. The computer readable medium of claim 9 further comprising executable instructions to:

decode said request as a transport command that includes any of the following generalized commands;

play, pause, next, previous, stop, shuffle, and repeat,

wherein said transport command is a generalized command that a universal music apparatus module executes to generate a respective server-specific command.

17. An apparatus for providing requests from a target electronic device as generalized commands for interacting with one or more specialized media servers operating with different server protocols, said apparatus comprising:

a universal media interface including;

a request decoder configured to decode a request to communicate with a specialized media server from a proprietary application program of a target device to form a decoded request; and

a command control protocol module configured to generate a generalized command for invoking a response from any of said one or more specialized media servers independent of said different server protocols, said generalized command being based on said decoded request.

18. The apparatus of claim 17 wherein said universal media interface is further configured to transmit said generalized command via a universal media data link to a universal music apparatus, wherein said universal music apparatus generates a server-specific command for said specialized media server in response to said generalized command.

19. The apparatus of claim 17 wherein said command control protocol module is further configured to generate a generalized command that initiates different discovery protocols to identify multiple specialized media servers.

20. The apparatus of claim 19 wherein said command control protocol module is further configured to generate another generalized command that initiates different communication protocols to interact with said multiple specialized media servers.

21. The apparatus of claim 20 wherein said different discovery protocols include Bonjour™

and Simple Service Discovery Protocol (“

SSDP”

), and said different communications protocols include Universal Plug and Play™

(“

UPnP”

) protocol and Digital Audio Access Protocol (“

DAAP”

).

22. The apparatus of claim 17 further comprising a universal media player application program interface (“

API”

) module for implementing at least said request decoder to decode instructions of said proprietary application program.

23. The apparatus of claim 17 wherein said target device is any consumer electronic device, including an A/V receiver, a television set, a personal digital assistant (“

PDA”

), a radio, a portable media player including a Digital Video Disc (“

DVD”

) player and a wireless phone.
