Apparatus and method of displaying electronic preview guide
First Claim
1. An electronic preview guide (EPG) display apparatus for use in a broadcast receiver, for selectively presenting viewers a broadcast schedule in a grid pattern with one or more rows each showing a TV channel number or a TV station name and an array of slots containing preview guide messages of the broadcast schedule extending in a direction of time axis, by using a preview guide data broadcast by each broadcast station and a present time, comprising a display controller for making an EPG slot at the present time or a viewer designated time wider than other slots of the EPG screen, wherein the display controller calculates a time difference between the present time or the viewer-designated time and the program start time, and then based on the calculated time difference, compresses the size of the slots in the EPG screen in a non-linear manner in the time-axis direction, so as to automatically change the amount of information to be displayed according to the size of the EPG slot in which the non-linear processing is performed.

7. An electronic preview guide (EPG) display apparatus for selectively displaying a program viewing schedule, the program viewing schedule having an axis showing a channel list and a time axis and defining a plurality of EPG slots corresponding to available programs, the electronic preview guide display apparatus having a display controller for displaying a reference EPG slot with a dimension greater than other displayed EPG slots, the dimensions of the slots being based on the proximity in the program viewing schedule of the slots to the reference EPG slot,
wherein the display controller determines the dimensions of the displayed EPG slots in the direction of the time axis based on non-linear, logarithmic processing of the time difference between the time of the reference EPG slot and the program time of the other displayed EPG slots.
