ABSTRACT:
Program data for use in electronic program guides is selected for storage at a low resource client according to a preference for current program data over program data for a future time. In the described implementation, a memory representative of the client memory is disproportionately allocated for different time units (e.g., 24-hour days) to be represented in an electronic program guide. Analysis is conducted as to whether program data for the different time units can fit in the portions of memory and adjustments to the amount of program data for respective time units are made. Different-size sets of program data are eventually selected such that more program data will be stored in the portion of memory corresponding to the current time unit and progressively less program data will be stored in other portions of memory corresponding to future time units.
