Abstract

It is determined that a substantial portion of set-top terminals connected to a video content network require a software upgrade. In-band video bandwidth (e.g., video-on-demand or switched digital video) is allocated for the software upgrade. The software upgrade is broadcast to the set-top terminals from a carousel in a first remote node of the video content network, via the allocated in-band video bandwidth, until a predetermined number of the set-top terminals have received the software upgrade. Subsequent to the predetermined number of set-top terminals receiving the software upgrade, the in-band video bandwidth is de-allocated and the software upgrade is made available out-of-band to the remaining portion of the set-top terminals, via individual sessions with an application server in a second remote node of the video content network. An exemplary system, which can implement the method, includes a controller, a dynamic bandwidth allocation device, the carousel, and the application server.

7. The method of claim 1, wherein:

said allocating of said in-band video bandwidth comprises a controller;

requesting said in-band video bandwidth, for said first remote node, from a dynamic bandwidth allocation device; and

indicating, in a transport field of an extended application information table broadcast to said consumer premises equipment, that said software upgrade is available on said allocated in-band video bandwidth; and

said de-allocating of said in-band video bandwidth comprises said controller;

advising said dynamic bandwidth allocation device to de-allocate said bandwidth from said first remote node; and

indicating in said transport field of said extended application information table broadcast to said consumer premises equipment that said software upgrade is available via said individual sessions with said second remote node.

8. A system for interacting with a plurality of consumer premises equipment over a video content network, said system comprising:

a controller configured to facilitate determining a software upgrade for said plurality of consumer premises equipment connected to a video content network;

a dynamic bandwidth allocation device, coupled to said controller, configured to allocate in-band video bandwidth on the video content network for said software upgrade;

a first remote node, coupled to said controller and said dynamic bandwidth allocation device, configured to broadcast said software upgrade to said plurality of consumer premises equipment, via said allocated in-band video bandwidth, until a predetermined number of said consumer premises equipment have received said software upgrade; and

a second remote node coupled to said dynamic bandwidth allocation device and said controller;

wherein said controller and said dynamic bandwidth allocation device are cooperatively configured such that, subsequent to said predetermined number of said consumer premises equipment receiving said software upgrade and a number of said consumer premises equipment downloading said software upgrade from said first remote node per unit time falling below a threshold capacity of a certain number of downloads per unit time of said second remote node, said in-band video bandwidth is de-allocated and said software upgrade is provided, out-of-band, to at least one remaining consumer premises equipment of the plurality of consumer premises equipment, via individual sessions with said second remote node over the video content network.

9. The system of claim 8, wherein said predetermined number comprises a predetermined fraction of said consumer premises equipment.

10. The system of claim 8, wherein said predetermined number comprises a predetermined absolute number of said consumer premises equipment.

11. The system of claim 8, wherein said second remote node comprises a hypertext transfer protocol server and said first remote node comprises a digital storage media command and control object carousel.

12. The system of claim 8, wherein said second remote node comprises a trivial file transfer protocol server and said first remote node comprises a common download carousel.

13. The system of claim 8, wherein said controller, said dynamic bandwidth allocation device, said first remote node, and said second remote node are located in a head end of the video content network.

14. The system of claim 8, wherein:

said controller allocates said in-band video bandwidth by;

requesting said in-band video bandwidth, for said first remote node, from said dynamic bandwidth allocation device; and

indicating, in a transport field of an extended application information table broadcast to said consumer premises equipment, that said software upgrade is available on said allocated in-band video bandwidth; and

said controller de-allocates said in-band video bandwidth by;
