Dynamic bandwidth allocation for addressable content
View Patent ↗Systems and methods for push-based dynamic bandwidth allocation deliver addressable, advertising content in a digital network. Bandwidth is allocated on a push basis in response to receiving a cue tone from a broadcast stream. The cue tone contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the cue tone. The addressable content stream is then streamed to a receiver during the addressable break and the receiver is tuned from the broadcast stream to the addressable content stream for the duration of the addressable break. The additional bandwidth is de-allocated at the end of the addressable break.
1. A method of allocating bandwidth comprising:
receiving a cue tone from a broadcast stream, the cue tone comprising data indicating at least the beginning of an addressable break in the broadcast stream;
allocating a portion of available bandwidth at a first time prior to the start-time of the addressable break to an addressable content stream based on the data of the cue tone;
streaming the addressable content stream to a receiver during the addressable break;
switching the receiver from the broadcast stream to the addressable content stream for the duration of the addressable break; and
de-allocating the portion of bandwidth at a second time after the end-time of the addressable break at the end of the addressable break.
2. A system for dynamically allocating bandwidth comprising:
a server comprising addressable content;
a splicer receiving a broadcast stream and inserting a stream of the addressable content from the storage server into the broadcast stream;
an edge device detecting a cue tone, the cue tone comprising a start-time and an end-time of the addressable break and data indicating at least the start of an addressable break, the edge device allocating a portion of available bandwidth to the stream of the addressable content based on the data of the cue tone for a duration, the edge device de-allocating the portion of bandwidth at the end of the duration of the addressable break,
wherein the edge device allocates the bandwidth at a first time prior to the start-time of the addressable break, and de-allocates the portion of bandwidth at a second time after the end-time of the addressable break.
3. The system of claim 2 further comprising a resource manager managing a pool of available bandwidth and allocating a portion of the available bandwidth to the edge device.
4. The system of claim 3 wherein the resource manager defines a plurality of subnetworks, the resource manager allocating the portion of available bandwidth based on a the targeted subscribers in each subnetwork.
5. The system of claim 4 wherein the resource manager allocates the portion of bandwidth in each subnetwork based on the active targeted subscribers in the subnetwork.
6. The system of claim 2 further comprising a traffic and billing module managing a schedule for addressable breaks.
7. The system of claim 2 further comprising an insertion module inserting non-addressable content into the broadcast stream.
8. A system for dynamically allocating bandwidth comprising:
a splicer receiving and transmitting a broadcast stream, the splicer detecting a cue tone, the cue tone comprising a start-time and an end-time of the addressable break and data indicating an addressable break; and
a server comprising addressable content, the server transmitting an addressable content stream, wherein the server allocates a portion of bandwidth at a first time prior to the start-time of the addressable break for a duration to the addressable content stream based on the data of the cue tone and the server de-allocates the portion of bandwidth de-allocates the portion of bandwidth at a second time after the end-time of the addressable break at the end of the duration of the addressable break.
9. The system of claim 8 further comprising a resource manager managing a pool of available bandwidth and allocating a portion of the available bandwidth to the server.
10. The system of claim 9 wherein the resource manager defines a plurality of subnetworks, the resource manager serving the portion of available bandwidth based on the targeted subscribers in each subnetwork.
11. The system of claim 10 wherein the resource manager allocates the portion of bandwidth based on the active targeted subscribers in each subnetwork.
12. The system of claim 8 further comprising a traffic and billing module managing a schedule for addressable breaks.
13. The system of claim 8 further comprising an insertion module inserting non-addressable content into the broadcast stream.
14. A system for dynamically allocating bandwidth comprising:
means for receiving a cue tone from a broadcast stream, the cue tone comprising data indicating at least the beginning of an addressable break in the broadcast stream;
means for allocating a portion of available at a first time prior to the start-time of the addressable break bandwidth to an addressable content stream based on the data of the cue tone;
means for streaming the addressable content stream to a receiver during the addressable break: and
means for de-allocating the portion of bandwidth at a second time after the end-time of the addressable break at the end of the addressable break.
15. The system of claim 14 further comprising means for splicing an advertisement into the addressable content stream to the receiver.
16. The system of claim 15 further comprising means for targeting the advertisement to a subscriber.
