Implementation of MPEG4/Markov Video Coder on M.E.R.I.T.E Platform

This paper describes the development and the implementation of an MPEG4/Markov encoder on embedded ALTERA RISC processor Nios 32. The MPEG4/Markov is an original encoder developed in our laboratory allowing to reach better performances than those realized with a classical MPEG4 video encoder. The purpose of this implementation is to validate the platform MERITE. It is architecture of a versatile platform for wireless sensor networks. This platform acquires environmental data and detects important variations in order to trigger some alarm. When some alarm is triggered on, data of the environment are compressed and sent on a wireless network
