Personalized MPEG2 Video-Data Transmission System

Abstract

A novel video system for providing personalized MPEG2 video content to each user is being developed. In this system, video servers multicast multi-angle video streams with meta-data (which describe the contents of the videos). The meta-data are created in relation to a "group of pictures" (GOP), which is capable of decoding itself without other video data. The gateway in the network produces a personalized video stream from multi-angle video streams according to the meta-data and a viewer's preference sent by the viewer. The gateway selects a video stream according to the GOP border from multi-angle video streams to satisfy the viewer's preference. It then sends the video stream to the viewer as one stream, even if it was created from multiple streams. The viewer can then watch a personalized video, which is created by connecting each scene without generating block-noise errors.
