—This paper considers the transmission performance of multimedia streams, especially Scalable Video Coding (SVC), over mobile WiMAX networks. SVC supports temporal, spatial, and quality scalabilities at bit-stream level, which enables the easy adaptation of video by selecting the subsets of bit-stream. Thus, SVC streams are more suitable than non-scalable(More)
As the graying workforce increases and the work patterns of our younger workers are more mobile, knowledge retention, attrition, and transfer become key determinants of the longevity of an organization. This is particularly true in edge organizations, which thrive on adaptability and agility to survive. In order for workforce development and succession(More)
—Scalable Video Coding is the latest extension of the famous Advance Video Coding standard. The main advantage of SVC is that it can provide scalability for visual services which are serving customers with heterogeneous network conditions and terminals' capabilities. Nevertheless , the multimedia service research community and industry have not been able to(More)
Joint source-channel decoding of variable length codes (VLC) for image and video streaming transmission over unreliable links, such as wireless networks, is a subject of increasing interest. This paper proposes an optimum maximum likelihood (ML) decoder of VLC sequences which exploits additional inherent redundancy in the source information, namely: (i) the(More)
Video conferencing service requires a multicast tree to distribute its multimedia contents to all participants. Link cost is very important in building such media distribution trees. In this research work, a multi-variable cost function is proposed. This cost function can calculate links' costs based on both network resources and application's requirements.(More)
