Abstract [en]

Nowadays, accessing broadcasted media can be essentially done either by terrestrial meansor through satellites. This broadcasting technologies have the advantage of a cost being mostlyindependent of the number of clients. In the mean time, television over Internet Protocol (IP)is spreading, especially because it allows for multi-screen playback, that is to say, one entry pointin the house, but multiple screens connected to it to enjoy broadcasted content. Furthermore,playback can be done on wireless devices, such as tablets. But for Internet Protocol TeleVision(IPTV) providers, the more clients that are connected, the higher the costs are.

Trying to combine advantages of both technologies, different actors chose to propose standardsto enable multi-screen offers on local area network when signal comes from a single satellitedish. This is achieved by carrying satellite signal on Internet network.

This report compares two major technologies, one relying on an old but time-tested protocol:Transmission Control Protocol (TCP); the other one, more recent, but dedicated: Real Time Protocol (RTP). While both behave perfectly on a perfect network, losses and degradationsin the video signal may occur on a real-world network. This behaviour can be quantifiedto help choosing between both solutions.

Results of this thesis show that, though TCP has the ability to ensure perfect delivery ofdata under normal circumstances, it behaves very badly under bad network conditions wheninput is a live content. RTP has always better performances, except with very low levels of networkimpairment. However, TCP is an old and stable solution that cost much less to implementthan a RTP solution and thus, some companies may opt for this less effective solution.
