Abstract
Optimized scanning for EPG data in the streams is provided by performing interim scans based on user data. The user data is gathered based on services accessed by one or more users of the device. The streams are then ranked according to the data and a scan threshold of a subset of streams to scan is defined. A interim scan occurs on a subset of streams up to the threshold streams after a first time interval after which scanning may end.
