Abstract

A method and apparatus for distributing multimedia content (such as video, games, music, pictures), where the multimedia content is stored in a plurality of set-top boxes that are connected to a cable network. A controller unit located at a central cable station manages the multimedia content. The multimedia content stored in the set-top boxes is made available to any set-top box on request to the controller in the central cable station. The controller unit also interfaces with a plurality of multimedia owners, many situated on the Internet, to source the multimedia content and to source service properties associated with the multimedia content. The controller unit informs the content owners and appropriate billing systems when a multimedia content has been delivered to a remote set-top box and has been consumed by an end user. The end user accesses the multimedia content through a television, a personal computer, or other multimedia appliance.

Claims

1. A method, comprising:

(a) splitting a video file into a first piece and a second piece, the video file being a digital representation of a video;

(b) moving the first piece through a cable network to a first building and storing the first piece in the first building on a first storage device, wherein the first storage device is disposed in a first set-top box;

(c) moving the second piece through the cable network to a second building and storing the second piece in the second building on a second storage device, wherein the second storage device is disposed in a second set-top box;

(d) moving the first piece from the first storage device through the cable network and into a third building, and storing the first piece in the third building on a third storage device, wherein the third storage device is disposed in a third set-top box;

(e) moving the second piece from the second storage device through the cable network and into the third building, and storing the second piece in the third building on the third storage device; and

(f) retrieving and displaying the first piece from the third storage device and substantially contiguously retrieving and displaying the second piece from the third storage device such that the video is displayed in the third building as a single unit.

2. The method of claim 1, wherein the splitting of (a) occurs in a central cable station.

3. The method of claim 1, wherein the splitting of (a) occurs in a distribution hub.

4. The method of claim 1, wherein the splitting of (a) is performed by a content provider, and wherein after the splitting of (a) the first piece and the second piece are supplied to a central cable station.

5. The method of claim 1, wherein the video file is an MPEG file.

6. The method of claim 1, wherein the cable network includes:

a distribution hub, a first fiber node, a second fiber node, a primary fiber optic network coupled to the distribution hub, a first secondary fiber optic network coupled to the distribution hub and to the first fiber node, a second secondary fiber optic network coupled to the distribution hub and to the second fiber node, a first tertiary network coupled to the first fiber node and extending to the first building and to the second building, and a second tertiary network coupled to the second fiber node and extending to the third building.

7. The method of claim 1, wherein the first storage device is a first hard disk disposed in the first TV set-top box, and wherein the second storage device is a second hard disk disposed in the second TV set-top box, and wherein the third storage device is a third hard disk disposed in the third TV set-top box.

8. The method of claim 1, wherein the first storage device is a first memory disposed in the first TV set-top box, and wherein the second storage device is a second memory disposed in the second TV set-top box, and wherein the third storage device is a third memory disposed in the third TV set-top box.

9. The method of claim 1, wherein the moving of (d) and the moving of (e) occur substantially simultaneously.

10. The method of claim 1, wherein the video is displayed in (f) in the third building on a television screen.

11. The method of claim 1, wherein the first piece moves from the first storage device in (d) with a first data rate DR1, wherein the second piece moves from the second storage device in (e) with a second data rate DR2, wherein the first and second pieces move into the third storage device in (d) and (e) with a combined data rate CDR, and wherein CDR is equal to or greater than the sum of DR1 and DR2.

12. The method of claim 1, further comprising:

(g) determining a downstream available bandwidth into the third storage device; and

(h) determining a first upstream available bandwidth out of the first storage device and determining a second upstream available bandwidth out of the second storage device; and

(i) based at least in part on (g) and (h), determining how the first an second pieces of the video file will move through the cable network to the third storage device.

13. The method of claim 12, wherein the first piece moves from the first storage device in (d) with a first data rate DR1, wherein the second piece moves from the second storage device in (e) with a second data rate DR2, and wherein the sum of DR1 and DR2 is approximately equal to the downstream available bandwidth determined in (g).

14. The method of claim 1, further comprising:

(g) viewing a web page on a television screen in the third building;

(h) selecting a link on the web page, the link being indicative of the video; and

(i) in response to the selecting of the link, initiating the moving of (d) and (e).

15. A method, comprising:

(a) splitting a multimedia file into a first piece and a second piece, the multimedia file being a digital representation of a multimedia content, wherein the multimedia content includes information taken from the group consisting of;

an amount of video, a game, an amount of music, a picture;

(b) moving the first piece through a cable television network to a first building and storing the first piece in the first building on a first set-top box;

(c) moving the second piece through the cable television network to a second building and storing the second piece in the second building on a second set-top box;

(d) selecting a link, wherein the link is indicative of the multimedia content;

(e) in response to the selecting of (d) moving the first piece from the first storage device through the cable television network and into a third building, and storing the first piece in the third building on a third set-top box;

(f) in response to the selecting of (d) moving the second piece from the second storage device through the cable television network and into the third building, and storing the second piece in the third building on the third set-top box; and

(g) retrieving the first and second pieces from the third set-top box and playing back or playing the first and second pieces in the third building as a single amount of multimedia content.

16. The method of claim 15, wherein the cable television network and the first and second and third set-top boxes form a storage area network, and wherein the single amount of multimedia content is played back or played on a wireless device having a screen.

17. The method of claim 15, wherein the first, second and third set-top boxes are coupled together via the cable television network so that the first, second and third set-top boxes form a storage area network, the storage area network further comprising a central controller, the central controller maintaining a map of where the multimedia content is stored in the storage area network.

18. The method of claim 15, wherein the cable television network is a cable IP network.

19. The method of claim 15, further comprising:
