The present invention relates to an interactive digital system enabling
viewers full and active participation in experiencing a live broadcast
event. Particularly, the presentation of the live event is personalized
for the viewer through the provision of various options, including
multiple video streams, associated with different camera angles, for
example, and integrated audio and graphics segments. Further, information
obtained from related Web sites can be integrated into the live program.
Various video and audio streams are collected from a live event and
forwarded to a central control studio. Graphics are created at the
central studio on a personal computer or chyron device. After receiving
the video, audio and graphics signals, the signals are digitized and
compressed in digital compressors. These signals are then combined with
special data codes into a "digital package," and subsequently,
transmitted over a cable distribution system. Once received at a viewer
home, the signals are received and processed in an interactive digital
cable box. Selections of the video, audio, graphics displays and/or Web
pages can be made as a function of immediate viewer entries, or to
interrogatory responses presented at the beginning or during the program,
or based on a prestored viewer profile. Once a decision is made to switch
from one video to another video option, the digital switch is performed
seamlessly. The digital interactive system is based upon seamless
branches which occur in the course of full-motion video.
