Content used in creating an electronic program guide and/or channels for a television reception system is delivered to a local receiving device, such as a direct to home satellite receiver, as individual digital objects. Rules (i.e., conditional expressions) may be embedded in the digital objects to allow different actions in different situations. These rules can be used to determine whether an object should be stored, which objects should be included in an electronic program guide, and/or what content should be used to create a particular channel.
