“…In such a case, multimedia streaming would be more efficient as it requires less bandwidth. Following this possibility, other approaches intercept X11 drawing commands and encode them in Moving Picture Experts Group Standard ISO/IEC 14496 (MPEG‐4) Binary Format for Scene (BiFS) . In these approaches, a scene creation module detects the graphical primitives generated by the X application, parses them and encodes them in multimedia BiFS.…”

SUMMARYVirtual desktop infrastructure (VDI) solutions seek to provide a satisfactory user experience at the client side when accessing remote desktop applications, even from mobile devices with limited capabilities. This paper presents a new approach, improving on previous work by the authors, in which a combination of Virtual Network Computing (VNC) and streaming protocols allowed efficient remote web access to virtualized applications within a cloud architecture. The new approach simplifies virtual machine templates, from which virtual machine instances are deployed, by centralizing software modules, greatly simplifying their management. Our new contribution consists of an integrated solution with specific WebM video encoding modules in charge of application visual output processing, an Hypertext Transfer Protocol (HTTP) streaming server, and a VNC server. The solution can be installed in the hypervisor of the host machines instead of replicating the servers and modules throughout the guest (virtual) machines that run the virtualized applications. Consequently, their implementations are unique and independent of the operating system of the virtual machines. In short, it is not necessary to provide different implementations for different operating systems, which reduces the complexity of virtual machine templates and greatly simplies platform management. To demonstrate our solution, we have modified the Quick Emulator (QEMU)-Kernel-based Virtual Machine (KVM) hypervisor source code accordingly. We also present qualitative and quantitative analyses that demonstrate that the new approach is advantageous in terms of software management and quality of experience, compared with our previous work and other well-known thin clients, contributing to the enhancement of VDI systems.

Current remote display technologies for mobile thin clients convert practically all types of graphical content into sequences of images rendered by the client. Consequently, important information concerning the content semantics is lost. The present paper goes beyond this bottleneck by developing a semantic multimedia remote display. Index Terms-semantic multimedia remote display, mobile thin client, MPEG-4 multimedia scene (BiFS, LASeR), X Window System, VNC-HEXTILE, RDP.
