Metadata enabled push-pull model for efficient low-latency video-content distribution over a network

Method, system, computer program and computer program product for a metadata enabled push-pull model and method for efficient low-latency video-content distribution over a network. Metadata is used as a vehicle and mechanism to enable intelligent decisions to be made on content distribution system operation. Metadata is data that contains information about the actual content, and in some cases, the metadata may also contain portions of the content or a low-resolution preview of the content. Aspects of the invention are directed toward the distribution of metadata throughout the network in a way that facilitates efficient system operation as well as optionally but advantageously providing set of services such as tracking, reporting, personalization, and the like.
