Abstract

A switched digital video (SDV) system includes an SDV manager for coordinating a SDV session requested by a subscriber terminal and a storage medium on which resides content to be transmitted during the SDV session. The system also includes a plurality of edge devices for receiving a transport stream that includes content provided by the storage medium and transmitting the transport stream over an access network to the subscriber terminal on one of a plurality of SDV channels. The SDV manager is configured to cause different renditions of an SDV program to be provided by the edge devices to subscriber terminals associated with different target groups. The target groups each include a plurality of subscriber terminals that is less than a number of subscriber terminals serviced by a distinct edge device or devices.

Claims

1. At least one computer-readable medium encoded with instructions which, when executed by a processor, performs a method including:

receiving a request from a first subscriber terminal to receive an SDV program over an access network;

selecting a first multicast stream from among a plurality of multicast streams that each carry a different rendition of the SDV program, wherein the selection is based at least in part on a first target group of subscriber terminals to which the first subscriber terminal belongs;

directing an edge device to issue a join request to receive the first selected multicast stream on which the SDV program is provided, wherein the first target group is a subset of subscriber terminals serviced by the edge device; and

directing the first subscriber terminal to tune to a first channel on which the SDV program is provided over the access network by the edge device.

2. The computer-readable medium of claim 1 further comprising:

receiving a request from a second subscriber terminal to receive the SDV program,

determining that the second subscriber terminal belongs to the first target group of subscribers; and

directing the second subscriber terminal to tune to the first channel.

3. The computer-readable medium of claim 1 further comprising:

receiving a request from a second subscriber terminal to receive the SDV program, said second subscriber belonging to a second target group of subscribers;

selecting a second multicast stream from among the plurality of multiplexed streams, wherein the selection is based at least in part on the second target group of subscriber terminals to which the second subscriber terminal belongs;

directing the edge device to issue a join request to receive the second selected multicast stream on which the SDV program is provided;

directing the second subscriber terminal to tune to a second channel on which the SDV program is provided over the access network by the edge device.

4. The computer-readable medium of claim 1 further comprising associating subscriber terminals with the first target group if the subscriber terminals have a common demographic.

5. The computer-readable medium of claim 1 wherein the access network is an HFC network and the edge device is a QAM modulator.

6. The computer-readable medium of claim 1 wherein the multicast stream is an IP multicast stream and the join request is an IGMP join request.

8. The computer-readable medium of claim 1 wherein the video stream is a unicast stream.

9. The computer-readable medium of claim 8 further comprising associating the first subscriber terminal with a second target group instead of the first target group based on content of an upcoming advertisement to be inserted into a rendition of the SDV program to be provided to the second target group.

10. The computer-readable medium of claim 1 wherein the video stream is a multicast stream.

11. The computer-readable medium of claim 10 further comprising directing the edge device to issue a join request to receive the multicast stream on which the SDV program is provided.

7. At least one computer-readable medium encoded with instructions which, when executed by a processor, performs a method including:

receiving a request from a first subscriber terminal belonging to a first target group to receive an SDV program over an access network;

directing a streaming server to transmit a video stream that carries the requested SDV program to an edge device such that the edge device delivers a first channel on which the SDV program carried by the video stream is provided;

causing at least one advertisement to be inserted into the SDV program before a segment of the video stream where the advertisement is to be inserted is transmitted to the edge device, wherein the advertisement is selected at least in part on the first target group to which the first subscriber belongs;

directing the first subscriber terminal to tune to the first channel on which the SDV program is provided by the edge device;

receiving a request from a second subscriber terminal to receive the SDV program; and

directing the second subscriber terminal to tune to the first channel if the second subscriber terminal also belongs to the first target group.

12. The computer-readable medium of claim 7 wherein, if the second subscriber terminal belongs to a second target group, further comprising:

directing the streaming server to transmit the video stream that carries the requested SDV program to the edge device such that the edge device delivers a second channel on which the SDV program carried by the video stream is provided;

causing at least one other advertisement to be inserted into the SDV program before a segment of the video stream where the advertisement is to be inserted is transmitted to the edge device for delivery on the second channel, wherein the other advertisement is selected at least in part on the second target group to which the second subscriber belongs; and

directing the second subscriber terminal to tune to the second channel on which the SDV program is provided by the edge device.

13. The computer-readable medium of claim 7 wherein the first target group is a subset of subscriber terminals serviced by the edge device.

14. The computer-readable medium of claim 7 wherein subscriber terminals in the first target group all have at least one common demographic.

15. A switched digital video (SDV) system, comprising:

an SDV manager for coordinating a SDV session requested by a subscriber terminal;

a storage medium on which resides content to be transmitted during the SDV session;

a plurality of edge devices for receiving a transport stream that includes content provided by the storage medium and transmitting the transport stream over an access network to the subscriber terminal on one of a plurality of SDV channels; and

wherein the SDV manager is configured to cause different renditions of an SDV program to be provided by the edge devices to subscriber terminals associated with different target groups, wherein the target groups each include a plurality of subscriber terminals that is less than a number of subscriber terminals serviced by a distinct edge device or devices.

16. The switched digital video system of claim 15 wherein the SDV manager is further configured to cause the different renditions of the SDV program to be multicast to the edge devices.

17. The switched digital video system of claim 15 wherein the SDV manager is further configured to cause the different renditions of the SDV program to be unicast to the edge devices.

18. The switched digital video system of claim 15 wherein the SDV manager is further configured to associate a first subscriber terminal with a second target group instead of a first target group based on content of an upcoming advertisement to be inserted into a rendition of the SDV program to be provided to the second target group.

19. The switched digital video system of claim 16 wherein the storage medium includes a streaming server for providing the transport streams to the edge devices.

20. The switched digital video system of claim 17 wherein the storage medium includes a streaming server for providing the transport streams to the edge devices.
