PROBLEM TO BE SOLVED: To provide different television programmings and different multiple interactive program guides to several different users respectively. SOLUTION: A multiple Interactive Program Guide (IPG) system provides different television programmings and different IPGs to several different users respectively. A single set-top box is capable of providing programmings and scheduling data to several different television sets. Each of the different IPGs share a common database. Therefore, an IPG being viewed by a first user of the system can display data added or modified via a second IPG by a second user. Furthermore, the data added or modified by the second user can influence the viewing rights of the first user. Also, all the competing and conflicting requests for limited sources, such as VCR scheduled recordings, will be brought to user's attention and will be displayed by the system.
