Analyzing internet protocol television data to support peer-assisted video-on-demand content delivery

摘要

A video-on-demand (VOD) server in an Internet protocol television (IPTV) network with a network of set-top boxes includes IPTV operational data and an analysis module that selects a content item. The VOD server divides the content item into sequential chunks, divides the chunks into stripes, pre-populates set-top boxes in a peering network with at least one stripe from each chunk, receives a request for the content item, and directs each set-top box to sequentially stream its stripes. A method includes selecting a content item based upon IPTV operational data, dividing the content item into sequential chunks, dividing the chunks into stripes, pre-populating set-top boxes in a peering network with at least one stripe from each chunk, receiving a request for the content item, and directing each set-top box to sequentially stream its stripes.

主权项

1. A device, comprising:
a processing system including a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations comprising: selecting a content item; determining a number of copies of the content item to reside on a peering network based on network operational data, the network operational data including power state data for a plurality of media processors forming the peering network, wherein the power state data indicates a number of the plurality of media processors expected to be powered off and accordingly unavailable to provide the content item; dividing copies of the content item into a plurality of sequential portions; dividing the plurality of sequential portions into a plurality of subportions; populating the plurality of media processors with a subportion from each of the plurality of sequential portions; and directing the plurality of media processors to sequentially stream subportions associated with successive sequential portions of the plurality of sequential portions to a media processor requesting the content item.
