Recently, there has been an increasing demand for high data rate communications for wireless technologies. With the integration of these technologies and multimedia services, transmitting high quality image and video has become one of the main objectives for the present and next generations of multimedia wireless network systems. In this paper, it is proposed to apply prioritized Trellis Coded Modulation (TCM) scheme employing Alamouti codes to H.264/AVC video bit streams for increased robust transmissions over MIMO channels. The channel data rate is kept constant at 1MBps whilst the source rate is varied according to the TCM Alamouti code rates.
