Abstract

A system and method for the aggregation of multimedia information storage via a broadband access gateway is disclosed. Information about storage resources accessible to a broadband access gateway may be collected and used in selecting storage capacity used for storing multimedia information such as, for example, streaming video, broadcast video, digitized video, digitized audio, text, and digitized images. The gateway may manage storage and retrieval of the multimedia information based upon user defined criteria and characteristics of the available storage resources. Multimedia information may be parsed for storage across multiple storage resources, and the location and nature of the storage resources used for storage of multimedia information items may be unknown to the user. Storage services accessible via a broadband connection may also be used as storage resources.
