Embodiments of the invention exploit the complementary and correlated information that is available across multiple channels of digital multimedia distribution, in order to ensure more efficient multimedia data access. One embodiment of the invention, directed to a method for generating a response to a specified request for information, is associated with multiple channels that are each adapted to carry and disseminate data content. The method comprises extracting data elements from each of the multiple channels, wherein each extracted data element pertains to one dimension of a plurality of correlation related dimensions. The method further comprises assigning each extracted data element to one of a plurality of correlation sets, wherein all the extracted data elements assigned to a particular set pertain to the same dimension, and each set is assigned data elements extracted from two or more different channels. Two or more of the correlation sets associated with the request are then selected, and the data content thereof is used to generate the response to the specified request.
