Abstract
Techniques are disclosed herein for merging EPG data associated with a variety of program sources. In one aspect, EPG data is accessed for different program sources and rules are selected that define how entries in the EPG data are to be merged. The rules may be selected based on whether the EPG data was collected in-band or out-of-band. In addition, the merging rules can be dependent on the program source, which allows the flexibility of applying different rules to different program sources. The EPG data from the different program sources is merged into a single EPG based on the selected rules.
