Abstract

An audio-video storage device includes a storage interface to interface with a storage medium that store a media file including video. The storage device includes a network interface to interface with a local network. The storage device performs replication of the stored media file. The storage device provides access to the media file to a first client device and a second client device over the local network and the wide area network respectively.

Claims

1. A multimedia storage server comprising:

a network interface to simultaneously provide a first client device and a second client device with audio-video network connections for editing on the multimedia storage server at least one of a plurality of components of a multimedia document that includes video and that is stored on the multimedia storage server, wherein structural relationships among the plurality of components form a basis for at least spatial layout and order of presentation of the multimedia document, and wherein editing includes inserting respective first and second sets of annotations in the multimedia document and to simultaneously provide a third client device with access to the video portion of the edited multimedia document and to at least the first and second sets of annotations; and

a storage interface to interface with storage facilities, the storage facilities to store video received from the first client device and the second client device respectively as first and second multimedia documents,

wherein the multimedia storage server is configured to;

receive from at least two of the first, second, and third client devices, requests for access to the edited multimedia document, wherein the request is communicated using IP protocol,

provide simultaneous access to the edited multimedia document including at least the first and second sets of annotations to the client devices requesting access, and

provide simultaneous access to the edited multimedia document to the client devices requesting access by enabling transfer of at least the video portion of the edited multimedia document to the client devices requesting access, and wherein the client devices requesting access to the edited multimedia document include respective decompression modules to decompress the transferred edited multimedia document for playback.

2. The multimedia storage server of claim 1, further comprising:

compression engines to compress video received from the first client device and the second client device over the audio-video network connections and to store the compressed audio-video respectively as first and second multimedia documents.

3. The multimedia storage server of claim 1, is further configured to perform at least one of creating, naming, time-stamping, retrieving, deleting, tagging, content-searching and playing back at least a portion of the multimedia document.

4. The multimedia storage server of claim 1, further comprising:

a decompression module to decompress the multimedia document.

5. The multimedia storage server of claim 1,

wherein enabling simultaneous file transfer of the multimedia document to two of the client devices requesting access of the multimedia document is over a local area network and a wide area network respectively.

6. The multimedia storage server of claim 1, is further configured to:

perform backup of the multimedia document.

7. The multimedia storage server of claim 1, wherein the multimedia document is stored on the storage facilities that comprise a plurality of disks, and wherein the multimedia storage server is further configured to:

perform replication of the multimedia document on at least two of the plurality of disks.

8. The multimedia storage server of claim 1, wherein the multimedia document is stored on the storage facilities that are internal to the audio-video storage device.

9. The multimedia storage server of claim 1, further configured to support go-to operations including at least one of a group consisting of a frame-number based operation and a time-code based operation.

10. A method of providing access to multimedia documents, comprising:

at a multimedia storage server,

storing video as a multimedia document;

defining structural relationships among individual components of the multimedia document;

receiving a first request for audio-video network connections from a first client device for editing at the multimedia storage server at least one of the components of the multimedia document, wherein the structural relationships among the components form a basis for at least spatial layout and order of presentation of the multimedia document, and wherein editing includes inserting a first set of annotations in the multimedia document;

receiving a second request for audio-video network connections from a second client device for editing at the multimedia storage server at least one of the components of the multimedia document, wherein the structural relationships among the components form a basis for at least spatial layout and order of presentation of the multimedia document, and wherein editing includes inserting a second set of annotations in the multimedia document;

receiving a third request for audio-video network connections from a third client device for playback of video associated with the edited multimedia document stored on the multimedia storage server, wherein the third request is communicated using IP protocol over a local network;

receiving a fourth request for audio-video network connections from a fourth client device for playback of video associated with the edited multimedia document stored on the multimedia storage server, wherein the fourth request is communicated using IP protocol over a wide area network;

providing simultaneous access to content of the edited multimedia document to the third client device and the fourth client device over the local network and the wide area network respectively by enabling transfer of at least video of the edited multimedia document to the third and fourth client devices for decompressing at the third and fourth client devices respectively; and

simultaneous to providing access to the video of the edited multimedia document to the third client device and the fourth client device, providing access to the third client device and the fourth client device to at least the first and second sets of annotations.

11. The method of claim 10, further comprising:

storing video received from the first client device and the second client device respectively as components of first and second multimedia documents.

12. The method of claim 11, further comprising:

tagging data associated with the first multimedia document such that the tagged data can be searched later to access a selected portion of the first multimedia document.

13. The method of claim 11, further comprising:

performing at least one of creating, naming, time-stamping, retrieving, deleting, tagging, content-searching and playing back at least a portion of the multimedia document.

14. The method of claim 10, further comprising:

compressing a respective audio-video input received from the first client device and the second client device.

15. The method of claim 10, further comprising:

performing replication of the stored multimedia document on at least two of a plurality of disks of storage facilities that are associated with the multimedia storage server.

16. The method of claim 15, wherein the storage facilities are internal to the multimedia storage server.

17. The method of claim 10, further comprising:

performing backup of the multimedia document.
