We developed a technique for watermarking an MPEG-2 video stream. Our method keeps the bit rate strictly within that of the input stream. Although the need for keeping the rate of a watermarked stream under control has been recognized for many years,

We present a video browsing system that dynamically extracts features and other content-description (meta-data) from compressed video. We devise a description scheme for a video browsing system that combines color and motion descriptors extracted in

A modern home could contain a large variety of devices and all of them should be able to work together so as to bring a rich experience to the users. Quality of service (QoS) is a critical factor for measuring user satisfaction. It represents the abi

In this paper, we propose a video coding scheme supporting direct 4:4:4 source format, which is designed as a straight-forward extension of MPEG-4 AVC/H.264 high profile coding. In the proposed scheme, each color component is encoded with independent

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 arch
