ABSTRACT:
A program identification system is provided to inform a user of an interactive viewing system of the identity of a program being viewed. The system may be implemented in an interactive television system in which a head end in two-way communication with multiple viewer stations provides a variety of programs over different channels to each viewer station. The programs may be video-based programs, computer executed applications, or other types of programs. Each viewer station can query the head end to learn the identity of a program, regardless of type, being viewed. The identity is then displayed to the user. Additional program specific information can also be obtained and displayed.
