Abstract

This paper presents an advanced video navigation concept based on a picture in picture (PiP) allowing combined rendering of fragments of normal-play video and fast search video simultaneously. Loss of audio during conventional fast search trick-play is eliminated, by adding the sound of the normal play fragment. The normal-play fragments provide detailed information, whereas the fast-search signal presents a course overview. The audio associated to the normal-play fragments enhances the navigation process, allowing the viewer to concentrate on either the normal play or the fast search window. Efficient signal processing in the MPEG-2 domain permits re-use of the standard MPEG-2 decoding path for decoding the normal play audiovisual fragments. Applying a scalable MPEG-2 decoder for decoding the fast search signal enables a low-cost implementation for personal video recording (PVR).
