Abstract

Limited bandwidth resources lead to a number of challenges especially for eHealth applications which are communicated over IP and wireless networks These multimedia services include highresolution videos and have very large file sizes that require a high level of compression to overcome this limitation Therefore there is an acute demand for the research community to provide an efficient multimedia framework to encode medical videos with high quality specifically under the conditions of an errorprone environment Both an affordable delivery framework and effective coding techniques are extremely desirable for the delivery of highquality eHealth video applications for transmission over heterogeneous networks and devices In this paper we propose and demonstrate a multimedia framework to support eHealth applications which has an improved coding scheme that uses an SVCscalable extension of MPEC4 AVC/H264 Simulation results show that the proposed scheme achieves a significant improvement in terms of the PSNRY gain and reduces the picture quality degradation caused by artifacts and distortions compared to the existing scheme
