In typical video-to-video transmissions, security and confidentiality is becoming an issue of greater importance, but these features come at a cost. In mobile environments, where CPU time is a valuable resource, such features should be thoroughly thought over as they usually require heavy computational resources. In this paper a short analysis on existing streaming solutions, standardised and otherwise, is performed while taking into consideration the scope of the LiveCity project of developing applications destined to the end-user. An analysis of different transmission protocols and their specifications, as well as encryption protocols designed to work on top of streamed data, is performed as a means to access which specifications better fit LiveCity requirements.
