Method and apparatus for content metadata search

摘要

A virtual dictionary contains keywords extracted from metadata describing multimedia content. A virtual keyboard of alphanumeric characters is configured for display on a display device such that as a character is selected from the virtual keyboard using navigation and selection controls associated with a set-top appliance only those alphanumeric characters which appear in sequence in one or more of the keywords contained in the virtual dictionary are displayed on the display device for a next selection.
