A method for acquiring and storing schedule event information from a cyclical broadcast in an interactive television system comprising a Head end (20), transmission media (32) and a client device such as a set top box (28) and display TV (26). An request queue for particular Event Information Table (EIT) schedule sections (42) is created and serviced in optimal fashion by selecting a section from the EIT request with the least acquisition latency based on the current position in the EIT broadcast cycle, the set top box (28) processing speed and the sequence of EIT sections (42) requested. |
