METHOD AND APPARATUS FOR RATING DATABASE OBJECTS

摘要

The invention relates to a method of rating database objects, such as broadcast programs in an EPG database. The objects are categorized in accordance with a multi-level category scheme with a first level of categories and a second level of categories subordinate to a respective category of the first level. The rating of a category of the first level is computed as a function, for example the average, of ratings of subordinate categories of the second level. Ratings are visually represented as different colors or different degrees of saturation of the same color.
