A system provides an intra-program event guide for display. The intra-program event guide enables a User to identify the events (e.g. scenes, episodes, alternative scenes, program portions etc.) occurring within a program and to initiate viewing (or initiate other functions associated with the event) via the guide. A method for processing information concerning intra-program events (e.g. comprising particular MPEG compatible groups of pictures (GOPS)) occurring within a program involves receiving signal data and identifying in the signal data information items describing intra-program events occurring during a program. The information items describing intra-program events are processed to provide processed data representative of intra-program events sequentially ordered by time and the processed data is communicated to a device. Generation of an intra-program event guide of the information items is initiated in response to user command. The guide shows other types of information items describing intra-program events scheduled for occurrence during a program. Such other types of events include, for example, (a) web page display, (b) software download, (c) PIP (Picture-in-Picture) image display, and (d) peripheral operation.
