MPEG video markup language and its applications to robust video transmission

In this research, we develop the MPEG video markup language (MPML) to describe MPEG-4 video contents. As an XML designed specifically for MPEG-4 bitstreams, MPML provides a friendly support for random access, portability, interoperability, flexibility, and extendibility. We propose an efficient compression algorithm to reduce the amount of storage space for MPML documents. Then, as two applications, we show how to use MPML for error-resilient video transmission over wireless channels and video multicast over Internet. It is demonstrated that the MPML-based decoding algorithm can protect image quality effectively against transmission errors over noisy channels by using the random access support of MPML.
