Date Sep. 18, 1997A television system has a television viewing mode (50) and a guide mode (56, 58). The guide mode includes an electronic program guide (EPG), which provides the viewer program information for tuned programs, and a tape index guide (TIG), which provides information for programs recorded on a video cassette (16). In both guides, real time images of a program are displayed in a PIP window (50) on the television screen and guide information (56, 58) is displayed in the background. In both guides, the viewer may switch between a currently telecast program or a recorded program. The viewer may access either guide from the television mode and vice versa. In the guide mode, the viewer may independently switch the guide information and the type of program, i.e., tuned or recorded, in the PIP window.
