Abstract: Techniques to create, generate, and deliver customized interactive program guide (custom-IPG). In one embodiment, selections indicative of a set of channels to be included in the custom-IPG are received. In response, one or more custom-IPG screens including the set of selected channels are rendered at a headend. Custom-IPG screens can be formed as subsets of the regular IPG screens, or as new screens. The rendered custom-IPG screens are provided from the head end to a set top terminal upon receiving a viewer request for the custom-IPG. Commands indicative of a particular location at which to overlay the custom-IPG screens may also be received, and the custom-IPG screens are re-rendered at the indicated location. Custom-IPG screens can be overlaid on a video sequence provided on a particular channel being viewed, used to carry regular program guide, or a channel independent of the channel used to carry regular programming and program guide.
