Abstract

A system, method, and computer program product are provided for delivering video content over a wide area network (WAN). Included is at least one server for transcoding or transrating the video content for delivery over the WAN.

Claims

1. A system, comprising:

at least one intermediate server for;

receiving a plurality of portions of video content from a source over a predetermined period of time; and

for each of the portions of the video content;

determining a portion of the predetermined period of time during which the portion of the video content was received;

selecting one of a plurality of additional servers according to the portion of the predetermined period of time during which the portion of the video content was received; and

distributing the portion of the video content to the selected one of the additional servers;

wherein each of the additional servers is associated with a different portion of the predetermined period of time, such that;

a first one of the additional servers that is associated with a first portion of the predetermined period of time is selected for distributing thereto portions of the video content received during the first portion of the predetermined period of time, and

a second one of the additional servers that is associated with a second portion of the predetermined period of time is selected for distributing thereto portions of the video content received during the second portion of the predetermined period of time.

2. The system as recited in claim 1, wherein the at least one intermediate server is one of a plurality of distributed servers in the wide area network.

3. The system as recited in claim 2, wherein the distributed servers are positioned at locations different from a location of the source of the video content.

4. The system as recited in claim 2, wherein the distributed servers include at least one first server for transcoding the video content.

5. The system as recited in claim 4, wherein the video content is transcoded into different formats.

6. The system as recited in claim 5, wherein the different formats include different resolutions.

7. The system as recited in claim 4, wherein a plurality of copies of the video content are stored each with a different format.

8. The system as recited in claim 5, wherein the at least one intermediate server delivers the video content in the different formats to the additional servers.

9. The system as recited in claim 8, wherein the least one first server, the at least one intermediate server, and the at least additional servers are hierarchically configured.

10. The system as recited in claim 8, wherein the additional servers deliver the video content to a client.

11. The system as recited in claim 9, wherein the additional servers select from the different formats for delivery of the video content to the client.

12. The system as recited in claim 11, wherein the additional servers transrate the video content for delivery to the client.

13. The system as recited in claim 1, wherein the video content includes video content received via a plurality of broadcast channels and transmitted to the at least one server for delivery over the wide area network.

14. The system as recited in claim 1, wherein the portion of the video content is distributed to the one of the additional servers selected according to the portion of the predetermined period of time during which the portion of the video content was received such that network traffic caused by multiple clients requesting the video content is distributed without causing duplication of storage.

15. The system as recited in claim 1, further comprising at least one server for transcoding or transrating the video content for delivery over a wide area network.

16. The system as recited in claim 15, wherein the at least one server is one of a plurality of distributed servers in the wide area network.

17. The system as recited in claim 16, wherein the at least one server that transcodes or transrates the video content is positioned at a location different from a location of the source of the video content.

18. The system as recited in claim 15, wherein the system operates such that the video content is time-shifted as a function of a time zone in which a client receiving the video content is located;

and wherein the system operates such that at least one aspect of the delivery relates to what advertisement content to deliver based on a particular audience and transmission medium, such that a first advertisement is delivered with the video content for receipt by a regional audience via a broadcast, the first advertisement targeted towards the regional audience reached by a broadcast antenna, and a second advertisement is delivered with the video content instead of the first advertisement for receipt by a worldwide audience via the wide area network, the second advertisement targeted towards the worldwide audience reached by the wide area network.

21. The system as recited in claim 1, wherein the different portions of the video content received over a predetermined period of time from the source are distributed to different additional servers according to a portion of the predetermined period of time in which each of the portions of the video content were received from the source, to distribute network traffic caused by multiple clients requesting the video content without causing duplication of storage, by:

identifying a first portion of the video content received over the first portion of the predetermined period of time from the source;

delivering the identified first portion of the video content to the first one of the additional servers associated with the first portion of the predetermined period of time;

identifying a second portion of the video content of the given source received over the second portion of the predetermined period of time from the source, the second portion of the predetermined period of time different from the first portion of the predetermined period of time; and

delivering the identified second portion of the video content to the second one of the additional servers associated with the second portion of the predetermined period of time.

19. A computer program product embodied on a computer readable medium, comprising:

computer code for receiving a plurality of portions of video content from a source over a predetermined period of time; and

for each of the portions of the video content, computer code for;

determining a portion of the predetermined period of time during which the portion of the video content was received;

selecting one of a plurality of additional servers according to the portion of the predetermined period of time during which the portion of the video content was received; and

distributing the portion of the video content to the selected one of the additional servers;

wherein each of the additional servers is associated with a different portion of the predetermined period of time, such that;

a first one of the additional servers that is associated with a first portion of the predetermined period of time is selected for distributing thereto portions of the video content received during the first portion of the predetermined period of time, and

a second one of the additional servers that is associated with a second portion of the predetermined period of time is selected for distributing thereto portions of the video content received during the second portion of the predetermined period of time.

20. A method, comprising

receiving a plurality of portions of video content from a source over a predetermined period of time;

and

for each of the portions of the video content;

determining a portion of the predetermined period of time during which the portion of the video content was received;

selecting one of a plurality of additional servers according to the portion of the predetermined period of time during which the portion of the video content was received; and

distributing the portion of the video content to the selected one of the additional servers;

wherein each of the additional servers is associated with a different portion of the predetermined period of time, such that;

a first one of the additional servers that is associated with a first portion of the predetermined period of time is selected for distributing thereto portions of the video content received during the first portion of the predetermined period of time, and

a second one of the additional servers that is associated with a second portion of the predetermined period of time is selected for distributing thereto portions of the video content received during the second portion of the predetermined period of time.
