Abstract
A video decoder system collates program guide information acquired from a variety of local and remote sources. Program guide information is received from a first source and a selectable program guide menu icon is displayed. A category of program guide information items from the first source is collated by a display attribute in response to selection of the menu icon and the collated program guide information items are displayed. The display attribute allocated to the category of program guide information items is common to both the category of items and to the menu icon. Codes identifying program categories may be converted to other codes using equivalence mapping information for classifying programs according to a master set of program categories. Composite program map information may be formed including new data identifiers allocated to program guide information items for use in retrieving the items from a second source.
