Abstract
An interactive cable TV system includes a large number of set-top terminals that are connected to a system headend by way of a low-speed, time division multiplexed, channel. The headend includes the mass storage of multimedia data-assets that each contain a large number of individual data-items that may be of interest to various set-top users. A set-top user initiates an inquiry to the data-asset storage by way of an item-descriptor comprising a word-picture of the item. When this set-top query is received at the headend, a table or list is established whereby the query and its set-top ID are associated with related data assets. As the headend's data-asset storage is changed from time to time, the changes that relate to listed set-top queries result in an update of the query list. This updated data-asset information is sent to the related set-tops immediately, or is sent only when the headend receives a request from the related set-top.
