This paper proposes a novel and efficient video delivery mechanism called Active Video Delivery (AVD) for large-scale video archival and retrieval systems. It considers the problems that exist in the current state of IP Multicast networks and addresses issues regarding the efficiency of a multiple video digest delivery over the Internet. Our multiple video digest display system will provide users with an initial multiple video digest preview upon their request, instead of requiring a direct download of large video files. With such a system in place two problems can be solved: (i) the shortening of time required for retrieving of videos from a peta-byte large-scale video archive; and (ii) helping users choose desired content more efficiently. In our analytic model, we observed that with a properly chosen AVD stream regeneration threshold, this digest mechanism allowed for a reduction in the video server bandwidth requirement and in the minimizing of network cost. In addition, in simulations conducted at our research lab using the AVD mechanism, which is based on the concept of Active Networks , the significant reduction of the video server load was achieved.
