Abstract

A method for audio and visual content download and playback includes downloading a clip that includes audio and visual content from a web site. It is contemplated the clip has been segmented into a plurality of smaller clips. The method continues with storing the metadata for the plurality of smaller clips in a local storage and initiating playback of the plurality of smaller clips. The method also includes displaying the content of a first of the plurality of smaller clips while a second of the plurality of smaller clips is being downloaded.

Claims

1. A method for audio and visual content download and playback, comprising:

identifying a downloadable clip at a web site, the downloadable clip being segmented into a plurality of smaller clips;

initiating a download of the plurality of smaller clips;

conveying metadata information of the plurality of smaller clips to local storage in a content download and playback device; and

a playback control engine accessing at least one of the plurality of smaller clips while at least one of the plurality of smaller clips is being downloaded to the content download and playback device.

2. The method of claim 1, wherein the initiating step includes making the metadata information of the plurality of smaller clips available to the content download and playback device.

3. The method of claim 1, wherein the metadata information of plurality of smaller clips includes a single playlist, a play item corresponding to each of the plurality of smaller clips, and a clip information file corresponding to each of the plurality of smaller clips.

4. The method of claim 1, additionally comprising:

the playback control engine receiving a command to playback a second one of the plurality of smaller clips; and

the playback control engine detecting that the content of the second one of the plurality of smaller clips is not accessible.

5. The method of claim 4, further comprising the playback control engine signaling that an error has occurred.

6. The method of claim 5 wherein an application produces an indication to the user that an error condition has been encountered by the playback control engine in response to the signaling step.

7. The method of claim 1, wherein the playback control engine generates audio signals and video images that are presented to the user in the event that the at least one of the plurality of smaller clips has been completely downloaded.

8. A method for audio and visual content download and playback, comprising:

downloading a clip that includes audio and visual content from a web site, the clip being segmented into a plurality of smaller clips;

storing the metadata for the plurality of smaller clips in a local storage,

initiating playback of the plurality of smaller clips;

displaying the content of a first of the plurality of smaller clips while a second of the plurality of smaller clips is being downloaded.

9. The method of claim 8, additionally comprising a playback control engine receiving a command to playback the second of the plurality of smaller clips.

10. The method of claim 9, additionally comprising the playback control engine signaling to an application the second of the plurality of smaller clips is not accessible.

11. The method of claim 10, additionally comprising:

the application requesting the second of the plurality of smaller clips from the web site.

12. A system for simultaneous audio and visual content presentation and download, comprising:

an application that contacts a web site and identifies and downloads a plurality of content clips along with metadata associated with each of the plurality of content clips; and

local storage that stores metadata corresponding to the plurality of content clips, the local storage being accessed by a playback control engine, wherein

the first of the plurality of smaller clips has been downloaded from the web site, and wherein

the second of the plurality of smaller clips has not been downloaded from the web site.

13. The system of claim 12, wherein the application initiates downloading of the second of the plurality of smaller clips upon receiving a signal from the playback control engine indicating that the second of the plurality of smaller clips is not accessible.

14. The system of claim 12, wherein the metadata includes at least one playlist and a plurality of play items wherein each of the play items corresponds to one of the plurality of smaller clips.

15. The system of claim 14, wherein a storage manager presents a virtual view to the playback control engine, wherein the virtual view includes content stored on an optical storage media, as well as stored in a local storage within the system for simultaneous audio and visual content presentation and download.

16. The system of claim 12, wherein the storage manager presents metadata corresponding to all of the plurality of smaller clips to the playback control engine.

17. An entertainment system that presents audio and visual content, comprising:

means for playing audio and visual content from an optical disc;

means for downloading an audio and visual content file from a web site, the audio and visual content file being segmented into at least a first and second audio and visual clip;

means for downloading metadata corresponding to the at least a first and second audio and visual clip;

means for presenting the first audio and visual clip to a user while downloading the second audio and visual clip.

18. The entertainment system of claim 17, wherein the means for playing audio and visual content from the optical disc includes at least one laser operating at approximately 405 nm.

19. The entertainment system of claim 17, additionally comprising means for presenting metadata corresponding to the first and second audio and visual clips to the means for playing audio and visual content from the optical disc.

20. The entertainment system of claim 17, additionally comprising means for downloading the second audio and visual clip even though the first audio and visual clip has not completed downloading.

21. The entertainment system of claim 17, additionally comprising means for indicating to the user that at least one of the first and second audio and visual clips is in the process of being downloaded.

22. In a content download and playback system, a method for simultaneous content download and playback, comprising:

a user inserting an optical disc that includes audio and visual content;

an application initiating a download of an audio and visual clip from a web site, the audio and visual clip being segmented into at least first and second smaller audio and visual clips; and

the content download and playback system playing to the user the first of the smaller audio and visual clips while the second of the smaller audio and visual clips is downloading from the web site.

23. The method of claim 22, additionally comprising storing metadata in a local storage accessible by a playback control engine of the content download and playback system, the metadata corresponding to the first and the second smaller audio and visual clips.

24. The method of claim 22, additionally comprising:

receiving a command from an application to playback the second of the smaller audio and visual clips; and

indicating to the application that the second smaller audio and visual clip has not been downloaded.
