Abstract

This paper proposes a highly flexible streaming video server that is particularly well suited for video-surveillance content. To achieve the required flexibility, the sequences are encoded with the JPEG 2000 coding scheme. To preserve compression efficiency, the temporal redundancy is exploited by a conditional replenishment technique. The main novelty of this paper consists in a post-compression rate allocation, which enables the server to adapt in real-time the content forwarded to heterogeneous clients using a single pre-compressed version of the sequence. An index is pre-calculated offline to reduce the computational load at the server while scheduling the packets in real-time, according to the needs and resources of the clients.
