摘要： A method for acquiring and storing schedule event information in an interactive television system. The schedule event information includes events and a start time and date for each of the events. The method includes creating a window defined by a start time and date and an end time and date and receiving the schedule event information at a receiving station. The schedule event information is stored for events having a start time and date within the window. The method further includes automatically moving the window forward relative to the start time and date at a specified interval such that the end time and date of the window are always after a current time and date. A system for acquiring and storing schedule event information is also disclosed.
