Interactive broadcasting is a type of broadcasting systems through which the viewer can enjoy interacting with TV programs from a broadcasting station using a bi-directional transmission channel. The target of the system is to provide programs where many people can participate at the same time and which have the following characteristics : -Viewers can participate in the program. -The program can change its presentation or the story sequence according to the viewer's command or response. -Viewers can change viewing angles and image contents. It can be thought of as a type of VOD systems through which a program can be viewed by many people at the same time. In addition to the functionality of program selection, a managing mechanism for more diversified response from viewers is needed. Further, aside from video and audio information itseif, ancillary data is useful to control the presentation and progression of the video and audio signals. In this paper we propose a basic command set for interactive broadcasting and useful ancillary data for interactive programs.
