- W52765836 abstract "In this work proposed here is framed in the project of research V3 (Video, Videoconference, and Visualization) of the Foundation i2CAT, that has for final goal to design and development of a platform of video, videoconference and independent visualization of resolution in high and super though inside new generation IP networks. i2CAT Foundation uses free software for achieving its goals. UltraGrid for the transmission of HD video is used and SAGE is used for distributed visualization among multiple monitors. The equipment used for management (capturing, sending, visualization, etc) of the high definition stream of work environment it has to be optimized so that all the disposable resources can be used, in order to improve the quality and stability of the platform. We are speaking about the treatment of datum flows of more of 1 Gbps with raw formats, so that the optimization of the use of the disposable resources of a system is given back a need. In this project it is evaluated the requirements for the high definition streams without compressing and a study of the current platform is carried out, in order to extract the functional requirements that an optimum system has to have to work in the best conditions. From this extracted information, a series of systems tests are carried out in order to improve the performance, from level of network until level of application. Different distributions of the Linux operating system have been proved in order to evaluate their performance. These are Debian 4 and openSUSE 10.3. The creation of a system from sources of software has also been proved in order to optimize its code in the compilation. It has been carried out with the help of Linux From Scratch project. It has also been tried to use systems Real Time (RT) with the distributions used. It offers more stability in the stream frame rate. Once operating systems has been test, it has proved different compilers in order to evaluate their efficiency. The GCC and the Intel C++ Compilers have proved, this second with more satisfactory results. Finally a Live CD has been carried out in order to include all the possible improvements in a system of easy distribution." @default.
