Scalable object-based video multicasting over the Internet

This paper presents a bitstream classification, prioritization, and transmission scheme specifically designed for MPEG4 video consisting of multiple video objects (MVO). Different types of data in the compressed bitstream such as shape, motion, and texture are re-assembled and assigned to different priority classes. We then propose a heterogeneous multicasting scheme for efficient packet delivery in a multi-party environment. Our proposed multicasting method is a single-layer solution with the advantage of multi-layer multicasting without the need of separate network sessions. Performance evaluation and test results indicate the advantages of the proposed scalable video transmission and multicasting scheme.
