Video Signal Analysis And Video Quality Enhancement
Subject area: Science,Engineering and Technology · Area of research: Electonics and telecommunication engineering
Abstract
An apparatus for detecting scene changes in audio/video signals is disclosed, together with video recording and logging apparatus employing such detection. The means for detecting scene changes comprises a filtering arrangement which receives and filters the audio soundtrack accompanying the video signal to periodically determine a background audio signal level. By comparison of current and previously determined background levels, a scene change is flagged when the current background audio level differs from a previous background level by more than a predetermined amount. A table of scene change locations may then be built up and stored with the video and audio data.
