A Strategy of Multimedia Reflectors to Encryption and Codification in Real Time

Abstract

The constant need of sharing data in information systems leads to the development of more complex and creative solutions to the physical or cost limitations of the nowadays technology. The main problems of a distributed system include: the huge information volume by time interval carried over the network infrastructure, and the confidentiality of the ongoing data. Going into the media transmission sub area, there are even more restrictions to be considered. Error or delay, for example, can drastically impact the user experience in real-time transmission. In this context, this paper proposes a tool for performing efficient and secure distribution and encryption of video streams. This tool was implemented and applied in several contexts. In order to validate the tool in a set of possible situations, tests of the video reflector were made using several sets of parameters evolving variations of video codecs and presence or absence of cryptography.
