Performance and Analysis of Video Streaming of Signals in Wireless Network Transmission

Abstract

In this work, we describe an effective video communication for wireless transmission of H.264/AVC medical ultrasound video over mobile WiMAX networks. Medical ultrasound is encoded using error resilient encoding in which, the quantization levels are varied according to the function of the diagnostic significance of image region. We explain how our proposed system allows for the transmission of high-resolution clinical video which is being encoded at the clinical acquisition resolution and then decoded with low delay. We perform this functional concept by using OPNET simulations of the mobile WiMAX medium and also considering some of the physical layer characteristics also such as service prioritization classes, different types of modulation being performed, fading channel’s conditions, coding schemes and their types and mobility. We are encoding the ultrasound videos at 4CIF (704×576) resolution to provide high level of clarity. The video quality assessment is being done based on both of their evaluations in objective and subjective manner.
