Paper Abstract

We describe a MPEG-7 Meta-Data enhanced Audio-Visual Encoder system that targets DVD recorders. We extract features in the compressed domain with both video and audio, which allows us to add the meta-data extraction without altering the hardware architecture of the encoder core. Our feature extraction algorithms are simple, and thus implementable through a simple combination of software and hardware on the integrated DVD chip. The primary application of the meta-data is video summarization, which enables rapid browsing of stored video by the end user. The simplicity of our summarization and feature extraction algorithms enables incorporation of the powerful functionality of smart content navigation through content summarization, into the DVD recorder at a low cost.
