Interactive video technology is meant to support user-interaction with video in scene objects associated with navigation in video segments and access to text-based metadata. Interactive TV is one of the most important applications of this area, which has required the development of standards, techniques and tools, such as MPEG-4 and MPEG-7, to create, to describe, to deliver and to present interactive content.
