dc.description.abstract |
In this document the Master thesis called “Development of an integrated
interface between SAGE and Ultragrid” is presented.
During this document, new users’ and companies’ necessities, that come from
the knowledge sharing to the productivity improvements, in the scope of the
advanced tools for videoconferencing are set out.
From these new necessities and after the analysis of the state of the art in
videoconference and high definition, a new technological challenge to solve
these necessities appears.
During the master a novel design is set out, a design for a new kind of High
Definition (uncompressed HD-SDI) videoconferencing system fully adaptable
and scalable. By joining different technologies of distributed visualization and
technologies of advanced streaming of high definition audiovisual contents
over IP networks, a new prototype has been deployed, able to solve the new
technological requirements.
The new deployed system is able to visualize several HD-SDI streams
simultaneously in a unique application. Also the new transmission/visualization
module, allows to divide the HD-SDI stream in different self-content substreams,
in order to give to the receptor user the possibility to choose,
according his capabilities, the number of sub-streams that will be able to
receive and process. This procedure will allow the user to always work with the
best quality he is able to.
The result of the thesis has been a high definition multi-videoconference low
latency system, able to work point to multi-point where each user receive
different resolutions, without transcoding.
Finally, the obtained results have been analyzed, opening new research lines,
and possible system improvements has been raised. |
